Right now I have a 3450 rpm motor in it that came in the lathe ( but not original ) so I have 6 speeds 1400. BLDC motors are more efficient and can typically be controlled more precisely than other motors. Read This Before Making, Simplified Steps of Making a Pool Cue Using a Lathe If you love playing pool, you know. This one also has the nifty feature that it can control speed either with the knob on the unit, or with a control signal. 700 , 545, back gear 250 , 145 , 55 . You are using an out of date browser. by LX Kid Tue Apr 28, 2015 8:47 am, Post Most of these lathes get down close to 1:1 (usually 1:1.2) on their pulley arrangements. Okay, who has been running my lathe backwards! Note that while my motor is rated at 2.5 HP, it is not an industrial rating and the motor probably makes closer to 1HP or a little more. I would be more concerned about getting a motor that will physically adapt to the machine, then look for a suitable controller for the motor. JavaScript is disabled. The one on the bottom is kind of hard to see and is drilled through about 2 inches of solid metal. Thanks, I will keep my eye open for one. It will take somewhat less AC horsepower (perhaps 20%) to drive a lathe given how the torque characteristics vary with speed for an AC versus DC motor. One warning about variable speed. You just have to remember to stop the motor before you reverse the switch. Spindle bearings - $96. Read This to Find Out Whether Natural Gas Generators Are Loud. You can see what it looks like (partially at least) down below. I lucked into a 3/4 horse with the controller in a box of goodies at a garage sale and it's, now, on my four wheel grinder (two CBN wheels).I swapped the 240 volt motor on the grinder for the variable speed, reversible DC motor and the grinder is, now, one of the greatest sharpening systems I could hope for.Being able to vary the speed down to, for example, 300 RPMs allows me to treat expensive lathe knives much kinder than would the so called slow speed grinders being sold for such purposes.ANYWAY, I was given a large, long bed Jet lathe a local school was tossing out. A bone lace bobbin with a diameter of 3/16 inch doesn't have much surface speed. For clarity's sake that is not a drum switch, it is a double throw toggle switch. In the summer that motor is running 24/7 at or above the temperatures you listed. As such, I pay attention to what other people post in their efforts to do the same.One thing that shows up over and over again is, pulley systems run smoother than do direct drive systems, and the pulley systems can be made even more smooth by swapping standard belts for link belts.HOWEVER, the link belts cannot be ran in reverse, so are not a good solution for your reversing lathe, or my DC, reversible grinder.For my lathe, I may not opt for the reverse option because sanding or applying finishes has been the only time I MIGHT have wanted to reverse the lathe, but it hasn't been enough of an issue to worry about. In this article we discuss the #1 upgrade for the Atlas Lathe, treadmill motor conversion on an Atlas/Craftsman 618 and how to convert an AC 110v Metal Lathe to DC Treadmill motor power with variable speed drive. today was the day. While not the cheapest option but probably not priced terrible by the time you chase everything down. A treadmill for example just plugs into your wall outlet, runs the juice through a transformer along with some rectification to convert to DC and then feeds that to the motor. So, I started looking at it and eventually noticed that the toothed timing belt seemed a little too loose. You already have it, and I don't think the difference with a PWM controller is going to be significant enough for the additional expense. Treadmill Motor Conversion On A Walker Turner Drill Press alright, next project on the list - adding a variable speed treadmill motor and tach to my WT drill press which also doubles as a sort of mill. Tip Carefully remove the motor, ensuring not to damage any wires. I also appears to be 2-3X bigger in size/volume of any treadmill motor. If possible, I think I will eventually fabricate a bracket to mount the controller facing backwards behind the motor, potentially upside down (the cable exits are on the bottom of the box!). JavaScript is disabled. Treadmill motor with KBIC drive, not vfd, but you must leave the pulleys and belts to allow the motor to run at enough speed to provide the horsepower needed for slow speed deep cuts and drilling operations. I have cleaned,repainted, and checked it mechanically. A site dedicated to enthusiasts of all skill levels and disciplines of the metalworking hobby. Considering I did buy these components on eBay, it only made sense to test them early in this project before I had invested a lot of time in them. Still think I will work on a shroud to keep the dust away from the motor, i tried my dust collector around the lathe, doesnt work!! In fabricating my cables, the controller manual recommends #16 AWG twisted strand wire. Fast & Free shipping on many . by LX Kid Tue Apr 28, 2015 8:54 pm, Post Lathe Modification: Tumbler Reverse & Hi-Low Gears, Better Servo Motor Tuning [ Mach3 and CNC applications ], Lathe Tailstock Camlock for a Mini-Lathe [Easy Time Saver], Get Goldilocks Feeds and Speeds for Best Speed and Longest. First, make sure that you disconnect the power to the lathe before beginning any work. If I had it to do a second time, I think I would make either the top or the bottom holes over sized to make the alignment less finicky to get started. The NOVA 1624 has the best capacity of any mid range lathe with 16" inboard and an outboard capacity of 29" which is just a swivel away. You are using an out of date browser. Not a bad thing necessarily for full size lathes turning large pieces from a safety standpoint but a real pain in the butt if your tuning pens at 3000 rpm and need to stop and inspect the wood frequently. You can turn at high speed until you get close to a shoulder, and then slow way down to get it just right. Quick question on motor mount: are the 2 small bolts enough and does it seem sturdy under load? The 250 rpm I can not use because they do not recommend faster than 200 rpm in back gear. It is an SCR controller, and you have a working one of those already. Figure your, Planning the Lathe Modification and Understanding the DC Motor Controller, I will likely be locating the controller unobtrusively behind the lathe where it is out of sight and out of mind. 1) Find a used 3Ph motor and run it on a VFD. Gemini Controls Treadmill Drive Installation & Adjustment, In our case we chose to mount the motor below the table and run the belt down rather than behind the lathe as was original design shown in the illustration below. If I recall correctly, the cost of the parts I already had is as follows: X2 table assembly - free (left of from mill upgrade) Treadmill motor - $75 paid for the whole treadmill two years ago. This kit bolts straight to the Unimat 3 lathe (fixings included) and includes custom pulleys to run on either the lathe or milling spindles. #1. I have an Optimum TU2506V, (V: read VFD) which has this setup and find it excellent. $125.62. Just my 2. He is great. Can a Portable Generator Get Wet? That turned out to be a non issue. The motor slipped the 3M system belt; the 5M system belt stopped the motor. (I googled it.) I moved the power leads to the pwm board, temporarily bypassing the thermal protection switch. It's also very fast at 4900rpm your old motor was 1440, other that it should work OK. Black is not a colour ! On the motor tag it says 3350 rpm, but when I put my tach on it, I can get 2925 in one direction and 2900 in the other. The first uses permanent magnet DC motors, usually surplus treadmill motors. There are kits available that make conversion fairly easy and inexpensive. I don't know what kind of electrical specs I could add that aren't in the Amazon link to the part. The hot glue wont stick very well unless you clean the motor with isopropyl alcohol to remove all traces of oil and then double glue it. Three terminal connections of which a 10,000 OHM rotary potentiometer is connected to. I have a Delta-Rockwell 46-12 wood lathe purchased on Craig List for $400. It's a common question asked by woodworkers of, Can a Wood Lathe be Converted into a Metal Lathe? So I need to keep that V spacing in mind. You can see what it looks like down below. Well done, and cleverly executed. Motor speed control - $56 off ebay in 2013. The second Running straight out of the box. In case I ever need to put the AC Motor back, here are the connections. 2. by LX Kid Tue Apr 28, 2015 9:29 pm, Post This belt is "delicate" and gets damaged easily and is very difficult to source locally. This forum is dedicated to those hobbyists with the 3-in-1 metalworking machines. The answer is yes! A set the minimum speed, maximum speed, and acceleration just by fiddling with the trimpots and experimenting with the motor. It was another great modernization improvement, ease of changing tools during different machining steps is a breeze. Here is the assembly as removed from the treadmill, Leeson 1.62hp motor, plenty of power. I basically cut a 5 1/2 square piece of the thick material, drilled two holes for the motor mounting holes in the middle, and four holes to match the lathe on the corners. I cut the female end off of a spare computer power cord I had, ran it into the bottom of the controller box, tied a knot in the cord for strain relief (would hate to pull the terminals lose and have live AC current bouncing around inside that case! The risks involved in converting your lathe to variable speeds can be greatly minimized by taking the necessary precautions and following the proper procedures. Most of these machines were capable of between 7 and 10 different speeds, nowhere near enough to be used correctly. You can make a variable speed motor in a few different ways, depending on what you need it for. The second one was the finished product.that you saw in the movie. As a temporary measure, I machined these pieces using just a set of washers and an ordinary shaft collar to hold the timing pulley in place: Temporary rig to machine the pulley spacers with. Second, there is a lot of bang for the buck. Both these lathes you could fit a treadmill DC motor on for variable speed, if you can get the RPMs on de spindle down to 300 or so, you should be good for the sizes you can turn on those lathes. @jimil. Look around for an old treadmill. You can also see the mounting plates. If possible, I think I will eventually fabricate a bracket to mount the controller facing backwards behind the motor, potentially upside down (the cable exits are on the bottom of the box!).

Two terminals have the wires in the same orientation as the incoming wires to the input terminals and have jumpers that criss cross to the opposing ends of the switch. The bearing housing at the brush end runs very hot. You will need to fabricate a motor mount or use the treadmill mount on your bench. Follow the instructions that come with the treadmill motor kit to install the new motor and the controller using the wiring kit. Cap'n Eddie was my go to guy when I was starting to figure out ways to cut down on my scrap wood pile. You must log in or register to reply here. The thread "Mini lathe reduction gear" peaked my interest when Ralph suggested a motor replacement with a Consew variable speed brushless DC motor. ), A 3hp motor should be 2237.1 Watts. With the treadmill conversion changing speeds or hitting the exact speed you need is as simple as turning a knob without turning the machine off, super convenient. In the words of Cap'n Eddie Castilin (Check out his YouTube channel).It's time to start "Makin' Shavin's". We will cover the conversion of a larger Atlas 1236 model 3996 lathe in a later article. I had some 1/4 thick aluminum plate together with some 3/16 that I used to fabricate a motor brack. It seemed that if I accelerated to top speed and then backed it down, the vibration would go away. Once the belt is removed, you can begin working on the conversion. DC Permanent Magnet with PWM controller (Great for torque at all speeds).2 wires to the motor (Usually). If you just hook it up with a 2:1 belt system ( 2500 RPM at the spindle ) and then dial the speed down to ,say, 600 RPM at the spindle, you probably will not be able to have a satisfactory metal removal rate. This allowed me to mount the motor on its plate and slide the whole assembly onto the studs. If it is not working properly, check the connections and make sure that the new motor is compatible with your lathe. Thanks Torch! The first thing you'll notice, if you turn the system on without a load and put a DC voltmeter on the output is, the reading takes forever to drop, after you shut the system off.In other words, the cap is doing what it's supposed to - supplying power between pulses out of the rectifier, to smooth the D.C. output.Again, thanks for the Ible. We happened to have a treadmill that was broken that we used as donor components of the motor and control board, the rest of the required items were purchased. Tips, techniques, modification and use of these machines is topical. Now get the best out of your 1624 by adding our renowned Striatech DVR Intelligent Variable Speed Drive. Many drill presses, cplishers, small lathes, etc have been converted to DC treadmill motors but the more successful conversions required some carefully made choices. Cost approx. I have done the same thing on my 12 X 36 and am very happy with the results. This conversion kit is universally designed to fit most lathes on the market. Second, there is a lot of bang for the buck. Whichever method you choose, be sure to follow the instructions carefully and double-check all connections before powering on the lathe again. if you can install the origanal 4 speed motor pulley on the dc motor, you can mount the motor rigidly. Read This to Find Out Whether You Can Run a Portable Generator in a Shed. Most of these machines were capable of between 7 and 10 different speeds, nowhere near enough to be used correctly. Regards Ian spro Posts: 8016 ;)I fell in love with variable speed motors long ago. Fabricate a custom control panel to fit the lathe. Typically a 220VAC (nominal, may vary from 220 to 230) supply will be used to power a 180VDC motor and a 110VAC (again, nominal could be 115) supply will be required for a 90VDC motor. I'm not familiar with either the treadmill controller or the the e-bike but speed/load regulation is a concern - if you set the lathe for a speed and then apply a cutting load, how does it handle that? You will need to fabricate a bracket for your application and mount the sensor and magnet. 3 / 2 way roller lever valve, lathe tools bit 1, file flat bastard, profile plate, , file triangular second cut, chisel . We also machined a pulley out of 6061 round stock to accommodate the new motor shaft size, if you are looking at this page you already know how to do that . ix. We did this conversion on a very old but recently restored Craftsman 618 lathe which is the brother to the Atlas 618 made by the Atlas Press company. I am building a new stand since the one it is on is not original and is not substantial enough for the heavy machine. Because no matter who you are, you deserve to experience the very best. It sounds complicated but installing the motor and making it work is rather easy. The link belt is easy to adjust size as necessary and it also does not hold a set like regular v-belts which cause machine vibration and chatter in small lathes. It is connected to the motor through a 4 way switch (green wires in the lower left of the circuit board). If you google images of 9" South Bend, you'll see what I mean. I also bought a bridge rectifier to change the AC from the motor controller to DC. The only other tool youll need is a drill and tap set. (This motor was supposedly rated at 3/4 horsepower, but those in the know say it's really more like 1/3 horsepower).I remembered that I've seen videos of how other people have used Treadmill Motors on other power equipment, so why not try to put one on the lathe? That price seems a little steep for my wallet. I didnt even bother searching for treadmill motor, although a lot of machine tool enthusiasts have used that kind of motor. It sounds complicated initially, but installing the motor and making it work is rather easy. Consider a 3 phase motor an a variable frequency drive. Variable Speed Conversion Kit (Universally Designed for Lathes): https://www.youtube.com/watch?v=FSMGOP01ulw, https://www.youtube.com/watch?v=ZFVuJ0hwNnw&t=194s. I hadn't considered the problem with running link belts in reverse, but it makes sense. If you're looking at South Bend countershafts, keep in mind that the lathe's headstock needs a place to attach the linkage that allows for adjustment of belt tension. There have been some really bad motor controllers that couldn't handle that situation (hopefully all in the past). Have fun and take care Leo Van Der Loo Comment PostCancel Thread Continues Below. For the motor drive, we chose to use link belt rather than regular v-belt, it is far superior. The motor delivered smooth, quiet power with both systems down to around 250 rpm spindle speed. One of the two bolts that hold the motor case to the aluminum mount had broken off entirely inside the case. You can find a treadmill motor kit at your local hardware store. Next, remove the belt from the lathe. 37129558 supply of ventilation fan motor ( foot mounted induction . I dialed it up to 30 or 40 rpm at the minimum. 31358 NEW 2 HP LEESON MOTOR $49.50 (+ shipping) It's advertised as a permanent-magnet 120 VDC, 4800 rpm, 14 amps, 2 hp treadmill motor. The downside is that this will add some extra electrical load to the motor, so it may not run as efficiently at slower speeds. After digging around a bit, I see a lot of people more knowledgeable on matters of electronics point out we can get better performance of our rectifier-controller circuits by adding a D.C. capacitor across the positive and negative D.C. output terminals of the bridge rectifier.It's indicated the first and most important thing in choosing a cap is, the voltage.
