Some of the angle aluminum. I used some standard 2mm copper wire scavenged from some old house wiring, and soldered on some cut (using a hacksaw) and flattened (hammer or vice) scrap of copper pipe. I used the 'threaded rod and nut' technique. Pull the fiberglass cover off the back of the lathe and check the oil level in the pump for the vari drive. Turning this baby on is one of those exciting moments where things should work nicely.By using the variable resistor you should be able to vary the light from completely off all the way through to full brightness. Then I began to clean it up.. DO NOT CONNECT THE MOTOR TO MAINS VOLTAGE without any load attached. hi, great instructable! It was quite some time before I cam across some scrap perspex - despite keeping my eyes open and a number of visits to our council skip/recycle centre. Working out which connections do what on the motor, is one of the first steps (see the photo below in which one of the brushes has been unbolted for clarity). This is important - say there is a power outage, you do not want your lathe bursting into life unexpectedly (when your not around or leaning against it) when the lights come back on. The premier source of parts and accessories for mini lathes and mini mills. It took slow speeds, cutting fluid, and lots of patience. One might be salvaged from some other device that has speed control: many modern vacuum cleaners have one, discarded power tools would be another possible source. Now we need to decide where and how we will fix the front and back faces. There are various ways to build a controller - probably the minimum and most basic is to vary the voltage with a variable transformer. I need to order some parts but I have no idea what brand it is. Grinding your own cutters is not that difficult and it's WAY cheaper than using carbide. The photos and descriptions tell it better than words up here. This didn't look quite strong enough, so I also used one of the 'proper' motor mounts, bolted to some aluminium channelling, which in turn bolted to the back panel.Using a tailors tape measure or a piece of string the belt length can be calculated. Once the steel is cleaned up the aluminium can bolt on top to create a smoother surface for the sliding tail stock. It cuts power to the NVRSS3 = Another relay that, when energized, completes a short circuit between the motor brushes.NVRS = The main on/off "no volt release switch".R1 = A resistor of about 10ohms (the larger the value the more gentle the braking effect)T1 = Step down transformer 240V to about 9VD1 = A diode that ensures the field coil is maintained in one direction. Start a stopwatch when the nut passes point A, stop the stopwatch when it passes point B. I have been told its an old Sieg. But, can anyone help my identify the make and model of my lathe? Possible sources: metal bed frames, surplus construction site materials, old gates, old trailer or other large machinery framework. Which I have finished repainting. First time I’ve seen ribbons while turning wood. The triac is going to need a way to cool off during continuous use. It is simply more fun to be able to control things. The plastic knob for the variable speed control was broken upon arrival. It came out of some offices and as far as I could tell must have been part of a table or something. To do this we will need the optional components mentioned earlier - a transformer (100VA should suffice - but see what you can find) and bridge rectifiers (these get quite hot, high current ones are a good idea). Did you use a triangular carbide insert or the round carbide insert for the acrylic? Keeping the speed at 50% or above will usually prevent overheating. How would I go about mounting/using it? There will likely be 3 stator coil connections,2 brush contacts,2 tachometer contacts,and an earth connection on the motor frame. my motor only has 4 wires, 2 brushes 2 coil. You can download tables with the correct corresponding sizes and print it out. Bolt your lathe down to the floor, and definitely wear a face shield to protect yourself. I dunno of a good table to look at this because the convective heat transfer should depend intimately on the shape of the sink. now this is were I'm getting a little confused. It also presents a safety hazard as attention is focused on the next task, while the lathe remains spinning and dangerous. Here is what I came up with, how I did it, the parts used, and the results. Because wood turning creates a decent amount of dust and wood debris, the motor will need encasing and protecting. e.g. All of the 7x lathes share some common mechanical quirks so there many modifications published to address the various issues; there … The current passing through the resistance wire should be enough to limit the speed of the motor. A variable speed grinder works in much the same way as a single-speed model does. Hopefully someone more knowledgeable will chime in, but if you are talking about single phase induction motors there are very limited options, the easiest and best usually being a mechanical solution using reduction pulleys or gears. Railroad Rail Lantern / Sign Stand Split With Axe. I wanted the ability to make food plates, which can come from stock that is quite thin (therefore not overly heavy) but has a reasonably large diameter. The friction caused the acrylic to get too hot. S1 = On button (push to make)S2 = Stop button (push to break) - if you make it this way S2 must be a very robust button as it will carry all the power going to the lathe. Make absolutely sure the workspace is clear and safe and your not going to have it accidentally knock over or into something conductive. Meaning that a lot of stopping and starting with full braking being applied can overheat the motor. 3) It was relativity pointless complication, which introduced more bits that might go wrong. Can you give details on it so I can find one that will work in it's place? (Dave Gingery) PS  to see more of what I have been up to with this you may want to check out my blog: www.floweringelbow.org Or if you want even more recent stuff, half finished projects and that sort of thing, like the Flowering Elbow page on facebook (also good if you want a quick response to a question). This last weekend I turned a large oak log that was out of balance. So what is the shaft speed if: it took 60 seconds to travel between A and B? You can buy a 1/4" HSS blank for less than $1.00 and it will last you a lifetime. Check out Youtube Clough42 channel. Right, so we need a rest which will support the chisel during cutting. Inline parallel shaft gearMolon, Toggle Switches,Switches,Electrical,SPST New. It may not display this or other websites correctly. However, there are significant advantages to having a braked motor, most importantly, you don't have to wait ages for it to spin down. Just connected the head piece right to the motor shaft. Same applies to main bearings and drive belt. This is because only the relatively flat poly-v belts can handle the sharp radius of the small motor drive shaft. I am starting to think this might be my first aluminium casting experience... Now to build a small furnace that will double as a bbq ;). The lathe is equipped with a 2A motor and variable speed controls so you can slow it down or speed it up as you need. 7 years ago It is essentially very simple and can be made using some strip board and a few cheap electronic components. When it comes to actually making the circuit, there is loads of good advice on soldering here on instructables, so I will not talk much about that. Chuck guard that comes with a micro switch for enhanced safety. Using sharp drill bits helps a lot! Someone asked for a drawing of the motor mounting plate. Grinding your own cutters .... Mal as Danny said you can get a much sharper edge with HSS. Basically you are looking for something long, straight, and strong enough to support a spinning log without undue flexing. ON/OFF slide switch. Literally the same day as I read it, my parents washing machine broke down. Snaps. I got a bit carried away and decided to attach a leadscrew to my tailstock base - this just allows you to move the base along the lathe bed by turning a screw (or peace of threaded rod in this case. Having the step pulleys between the motor and load will allow you to run the lathe very slow and still be variable in speed within the slow pulley/belt position without slowing the motor to less than 50%. 2. It isn't a "put this gear here". In other words when you start turning your wood and you push the cutting tool into it, the speed will fluctuate wildly. If not you can skip this step. WEN 3424T Mini-Wood Lathe. If i want to tap a 6mm thread (because I want to use a 6mm bolt) and if the thread pitch is 1mm, then the drill bit size would be 6mm - 1mm = 5mm drill bit. The picture shows an old washing machine motor salvaged from a machine my parents were throwing out. The tailstock is from a bike. And, some more testing with a piece of Bethlehem Olive wood. almost the same as this lathe machine of yours but the wiring is too complicating! Definitely one I’m gonna have to copy. There are true electronic variable-speed lathes with DC motors these days and others that offer lever-controlled, clutch-type variable speed changing. If you really want to do it, though, it is most likely that you will find that it does not really cost very much and it is not nearly as technical and dangerous as established experts would have you believe." In part 1 he discussed his experiences with grinding bits, why he uses a belt sander instead of a bench grinder and introduced some terminology about tool bit shapes and angles. You need to know the pitch of the thread (i used some 1mm pitch stuff) Mark two places on the rod (A and B), a given distance apart (say 60cm).Now set the lathe running at a slowish speed and record the multimeter reading. please need help! Check each track, to ensure it is not accidentally connected to any other. I hope you got something out of this instructable and look forward to any comments you might have. S2 = A relay that gets power and therefore energizes, when S1 is pressed. Although, convection is more relevant here, so that point is kind of moot. The electronics is the only thing which differs from your design. You can now work out the rpm (revs per minuet).. The aluminum was turned with a Korloy 9mm round carbide insert designed for aluminum. Anyway with a bit of polishing up it would be clear and do the job perfectly. Definitely one I’m gonna have to copy. The triac itself can often be salvaged from the washing machines along with the motor. For this application a poly-v belt is best. to provide needed support for chisels and tools during operation and a 3.2 Amp motor to keep things turning. As headstock consists of parts from an axle from a big trailer. You could buy a standard heatsink from Maplin or similar or make your own. The calculation to get a maximum ballpark speed for your bowl blank on a wood lathe is as follows. This way you can accommodate different sizes of wood between the centres. I like making stuff, and learning about how things work.

(1959 P90 Lathe - Reeves Drive w/VFD), Index/Menu of all IAP Tutorials (Last Update 1/2/2021), Wood Lathe Will be For Sale if there is an Interest. Simply attach the multimeter to the tacho output, set to read voltage (20V scale). That's an amazingly nice cut on the Ebonite, Danny !! I used a #20 drill bit to drill the lathe bed. The speed control display is in percent of the motor speed. This uncontrolled speed is bad because: a) it is going to make a lot of noise, annoying you and your neighbours; b) to turn wood on a lathe we will need a much lower rpm - from about 400 - 2000. If you go with a variable frequency drive (expensive), it means that you will also need to get a three-phase motor and it will need to be larger than the one that you currently have to make … Ideally you would like the rpm to remain predictably constant, rather than speeding up and slowing down as you make your master-works on the lathe. This would have been easier with a drill press (that will have to be a future project though), but you can make do with a decent hand drill - and get quite skilled at using it in the process.. Use plenty of light oil on the drill bits, and go at a slow speed. Great job Danny! This on its own looked to be a bit flimsy, so I also rescued a long peace of angle iron that was rusting away at my parents farmhouse. I already had two stainless bits which would add a tough outer shell and little bit of rigidity. You can use it to make beautiful birthday and Christmas pressies for family and friends and to craft all manner of things to help in other projects. Drill your holes, then, clean and polish all joining surfaces. When you have completed the basic circuit, look it over a lot' - check for boo boos and out of place solder. Not just that, the Reversing and Forward system ensures superior finish. I was lucky in that Boeing, Bombardier, Cessna, Lockheed etc were very fussy about that sort of thing so when we as a subcontractor got the paperwork there were few errors. Slightly overkill, but it works brilliantly and can definitely stands the forces. It incorporates parts from the washing machine electronics. The variable speed controller comes with the potentiometer and an on off switch wired in. His explanation of threading is the best I've ever seen. For the wood lathe - which is what we are making here - people have used various materials to form the bed of the lathe. It's just the bearing, no cap or housing or anything. It has to be this old type - new compact fluorescent ones will not like the chopped current. These motors can be run off both DC and AC making them quite versatile little beasties. He really shows the math and why it works. CSA and UL Listed. Comes with easy-to-read digital readout to quickly … Basically this switch will start from a push button but if there is a power cut for any reason, it will not automatically restart when the power is restored. The spindle is rather simple: everything needs to be screwed into place. In the picture I am testing the motor with a DC bench supply, made from an old computer PSU (power supply unit - check out Sitnalta's instructable). It is essentially the same stuff that is in a light dimmer switch, all be it beefed up a bit so it can handle higher current. Sir since I live in the pacific islands there's lots of coconuts and I want to make a coconut meat grater using a discarded washing machine motor! Twist the knob of the dimmer slowly to the right to increase the voltage, thereby increasing the speed of the lathe. Test it briefly then disconnect from the mains (well ok, you can play with it a little bit, but remember those connections are live, and the crock clips don't exactly meet domestic wiring regulations). Take the diameter (D) of the bowl divided by 9,000 9000 / D = Maximum RPMs For Example: 10 Inch Bowl = 9,000 / 10 = 900 RPMs Maximum Remember the further the drive shaft is from the bed the more leverage it has and the more likely it is to do cheeky twisting, wobbling and other dangerous things. Be greatly blessed Sir and invent on! The only difference is you get to choose which speed is the best for you and the project you are working on. If you want to make something like this yourself, and you plan, as I did, to spend very little and to recycle other peoples landfill material, you certainly will have to think 'outside the box' as you put materials and things to new and unintended uses. It has zero-phase detection for proper speed control. I chose to make my own (to better understand it and to and add some mods). It can reverse, break, and dynamically adjusts the power. To make yourself a load of wooden kitchen bowls, plates, utensils, etc. It is important to cover away the drive belt anyway - exposed it presents an intolerable safety risk. I got ideas from lots of places on the internet (including other instructables - do a search for 'lathe') and formulated my design as I collected materials. What a gift you have Sir and Im awed at your brilliance and good heart for sharing!! It eliminates all the change gears. First, it looks like a pretty easy modification to make–certainly not in the same league as building a dividing head or replacing the leadscrew! Be blessed and stay blessed!! Bring forth a scrap bike frame, an angle grinder, and I was on my way (see pics)... Something reasonably rigid that swivels and can be moved towards and away from the wood and be locked in place, and that has something that the gouge can slide along, side to side. I don't use the variable speed at all. More Galleries of Variable Speed Wood Lathe :. What I needed was a banjo. A variable speed lathe is used when more cutting control and variation is needed to complete a project. This is the lathe, a Rockwell 46-111, circa 1974. Lathe Modification: Variable Speed Treadmill DC Motor. The speed change can be orchestrated through a pedal, like a sewing machine. Now I wish I hadn't bought the Sears lathe. Automatic feed. The pulse-width-modulation circuit that we want can be made in a number of ways. Record the time it took. were do i wire the different motor wires too. Find the symptoms your lathe exhibits, and … My solution, is to have a push button (S1), normally open, that, when pushed (and held down), makes a separate circuit that both powers the field coil and energizes a solenoid relay (S3), which shorts the brushes through resistor R1.Key to diagram:S1 = Push switch - the main switch that the user pushes, and holds, to cause braking. Very cool Danny. Also check out the diagram that shows what bits of the motor are what. (see for more info on taper bearings: http://www.arceurotrade.co.uk/projects/C3_BC/pages/index.html). I tried to mount the components that might get warm, like the rectifiers and the braking resistor, to the metal panels to help dissipate the heat. 8K™ Lathe Dating back to 1931, the first South Bend 8" Bench Lathe made it much easier for machinists around the world to own a professional-duty lathe of exacting precision that was built to provide a lifetime of dependable service. I like the ingenuity in this build!Being in the US,I have different voltage obviously.Do you know if the circuits you built would work for 110AC motors? You, my friend, are a fine and awesome artist! I do have a taper bearing I found laying around in my toolbox. i get were the two brushes go to but the coil wires i don't. Troubleshooting the Mini Lathe Variable Speed Drive There are several common types of failure that occur on the mini lathe's variable speed drive. DELTA 46-745, 46-746, 46-765X 16" Variable Speed Wood 22" X 42" Variable-Speed Wood Lathe Wood Lathe Jet 1220 Mid-'60's Rockwell Lathe Variable Speed Help The Wood Knack: Rockwell Delta 46-111 Lathe, Part 1: Overview Wood Turning Lathe. Series wound motors have no theoretical limit to their speed and the centrifugal forces can fling the motor armature apart! So, I set out to slow down the feed rate. Save your money for a new bigger and better lathe. It also lends itself to grinding custom shapes like cutting little coves, beads, round over shapes grooves etc. Also you get to learn some cool electronics jazz! 7 years ago Grizzly H8259 Pen Turning Wood Lathe for Pen Turning. I would love to hear what you guys use to make your designs.A more complete and up to date set of instructions for this project and videos of the lathe, and other bits and bobs can be found on our blog at: http://www.floweringelbow.co.uk. Can you point me in the right direction for a speed control solution for a capacitor start ac motor? To achieve this without some sort of electronic control would mean an elaborate (read even more noisy) and large pulley system, and,c) if connected straight to the mains the speed regulation will be poor when load is applied to the motor. That’s an amazing finish right off the turning tool. To do this we rectify the speed controller output and supply the motor with DC (direct current). Not ignoring that sign I started building my own, inspired by yours. Replace the knob and turn the dimmer to the off position. JavaScript is disabled. Variable speed is nice but the lowest speed settings should be slower as it is too fast when trueing up a large piece of wood and the lathe wants to jump around a little bit too much at that speed. Overall, the electronically variable speed is very helpful in many situations but especially while learning to use a 7x lathe. Mine is a VERY snug fit and was nearly impossible to push up and down the rails by hand - which is partly why I wanted the lead screw. The JET 1221 Electronic Variable Speed Midi Wood Lathe was designed to provide you with the ultimate control while turning and provides a wide range of features that make your turning experience more enjoyable. It can't be too strong, but consider the weight and size ;) Mine ended up being much heavier than expected and I need help to move it about. on Introduction. Electronic speed control is highly desirable for washing machine, and other series wound, commutator motors. And here is a picture of the mounting plate off the lathe. This creates a braking force and the energy is dissipated as heat in the armature. Grinding your own cutters is not that difficult and it's WAY cheaper than using carbide. As shown in the diagram, we still keep the 240V DC running through the field coil as well, this gives the benefit of reducing starting current surges. [edit; for some reason Blogger deleted the photos so I have edited this blog with updated info and pics.] If you do get a washing machine motor try and grab the whole machine - then in the comfort of your own home you can take your time to work out how the wiring went. So it pumps more juice into the motor when it gets slower due to high loads, which makes it a smooth experience to work with and almost impossible to make it go slower when working intensely. can you help me with this project!?? You need to make sure all the wires are kept firmly in place, away from the moving parts. Super subjective I know, so it is a good idea to design some adjustment into the motor mount. As you can see the steel is well rusty and actually quite pitted but is hopefully still thick enough to add the rigidity we're after. one of the most impressive instructable on net. You can buy them ready to fit off e-bay or make your own if you have a good high current contact relay and a push to make and push to break buttons in your scrap box. You are using an out of date browser. As my triac is rated at 26amps I am not too worried about it- but something to lick the heat away is needed. If all is well you can test it with a 60W incandescent light bulb. 89 A variable speed motor in a wood lathe gives the tool the ability to change speeds as needed. Thanks to Westfw for the Eagle schematic 'able (https://www.instructables.com/id/Draw-Electronic-Schematics-with-CadSoft-EAGLE/). VR1 Variable resistor or POT 220kR1 Min Resistor 4k7 (if you plan on making electronics project get a resistor pack like this)R2 Min Resistor 22k R3 Min Resistor 100R D1 Diac DB3T1 Triac BTA26-600B (the 16A version would suffice - I was in an overkill mood) Some strip board to put it all on.Optional components (more on this later):2X Rectifier J04 (BH46A) ~ �3 each (but I got very similar ones on e-bay for 99p each) 50VA Step down transformer 240V to 9V - (search out old power supplies, audio amps, hi fi's, etc.) For a better experience, please enable JavaScript in your browser before proceeding. That's right, a BANJO, a piece that fits onto the bed and supports the actual rest. In unusual circumstances, It might also endanger your work piece to have a dramatic change of speed. Answer: 600rpm because it revolved 600 times in one min...If we make a little table or rpm with corresponding voltage readings we only need a few reading and can draw a graph (which should be a straight line) to give us the rpm, at any given voltage. Check out Youtube Clough42 channel. 6 years ago Make sure everything will fit before you start cutting or drilling - cardboard mock ups are useful! If it's 3 phase you can use a variable frequency drive, which gives a great solution. The materials I found for this were: Coming from an old piece of machinery, one surprisingly heavy and large sheet of metal, about 6mm thick (strong stuff!). Simply the best, most detailed and well written instructable I've read so far. I used some more scrap alu angle to make fixing runners. Thanks for sharing. To me though, it seems completely sensible. Using the change gears in a mini lathe, the finest feed you can get is 256 threads per inch. This motor mounts with #10 32 tpi screws. The H8259 wood lathe from Grizzly is a top … It has a swing capacity of 12-1/2-Inch, which makes it the best wood lathe available in the market. It also has an MT1 spindle and tailstock taper to tightly grip workpieces with a lever-clamping system to make adjustments easy. That's a hard one. The premium for variable speed appears to be outrageous from the manufacturers and in this case one gets the bonus of a spare motor after plus the parts are non propriety but also the removable control would be ideal for lathe work to put it where you want it or even make … I needed to make a hole in the front panel for the bed angles to fit through, I did this with small angle grinder and some filing. on Step 22. Check out his youtube channel: www.youtube.com/floweringelbow, https://www.instructables.com/id/Draw-Electronic-Schematics-with-CadSoft-EAGLE/, http://www.arceurotrade.co.uk/projects/C3_BC/pages/index.html, https://www.instructables.com/id/Sharpen-Your-Drill-Bits/, How to Make Charcuterie Boards Using Clear Acrylic Templates. It works great for what I want. Eventually I hit the jackpot when I found some scrapped 15mm thick translucent perspex. This is a problem because in general we want braking to coincide with a cut in the power to the unit. Again no sanding. Old motor shaft, bearings and bearing housings. There are a number of different ways to do this. I had recently replaced my variable speed 2 hp motor with a 5 hp motor. should I follow your rewiring of the motor you did!?? If you go fast you will harden the steel your trying to drill and dull the drill bit, making it really difficult. Making a lathe is fun! Awesome job!P.S.I didn't know you can buy stuff from recycling points in UK... 5 years ago As rails I decided to go for pipes, since they were free. The tailstock will slide along the rails of the lathe bed. Hold a nut stationary on the rotating rod - it will travel lengthways along the rod, because the rod is spinning. It's sorta' like putting lipstick on a pig. I'm planning to make my own lathe like Mark has and like the one that Richie Dotson shows on his web site. See circuit diagram. I still wanted to keep an eye on what was going on inside while the lathe was running though, so the plan was to find some thickish perspex to cover the top. 45 RPM 24 Volt DC Molon Gearmotor, DC Gearmotors, 45 RPM 24 VDC MOLON GEARMOTOR, 45 RPM, 24 DC • New MOLON take-offs.
