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. 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. You might not always want it to rush to a halt - doing so puts extra strain on the belt, bearings and other components. That's right, a BANJO, a piece that fits onto the bed and supports the actual rest. i get were the two brushes go to but the coil wires i don't. This last weekend I turned a large oak log that was out of balance. “With a variable speed metal lathe like the LeBlond RKL, you get the RPM to match up to your cutting feed rate and the surface finish you want on a piece,” Cook says. almost the same as this lathe machine of yours but the wiring is too complicating! Delta’s wood lathe provides you with three-pulley ranges to choose from as per your need. 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. Basically you are looking for something long, straight, and strong enough to support a spinning log without undue flexing. Super subjective I know, so it is a good idea to design some adjustment into the motor mount. He really shows the math and why it works. In this same tradition, we are proud to offer the SB1001 8K Variable-Speed Bench Lathe. Also, no transformer, so 230V all the way. Glad you took it as intended Danny. Using sharp drill bits helps a lot! Definitely one I’m gonna have to copy. Making a lathe is fun! 2. It is a good safety feature to have a so called 'no volt release switch' on your lathe. It is essentially very simple and can be made using some strip board and a few cheap electronic components. It also has an MT1 spindle and tailstock taper to tightly grip workpieces with a lever-clamping system to make adjustments easy. This spin down time can be quite substantial if your turning something hefty. 7 years ago Slightly overkill, but it works brilliantly and can definitely stands the forces. 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. Be blessed and stay blessed!! ON/OFF slide switch. Reading over the various potential modifications, I decided the DC motor needed to come fairly early in the process for several reasons. 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). 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. He loves to learn about, share, invent, and make things, particularly from waste materials. It works great for what I want. This is the lathe, a Rockwell 46-111, circa 1974. I decided not to have speed control or any belts/gears. Almost all electronic braking (on series motors) works by shorting the brushes together with a resistor - effectively turning the motor into a generator. Grinding your own cutters is not that difficult and it's WAY cheaper than using carbide. It needs to take drive from a motor, transfer it, through a belt to a shaft that you will attach the wood you're working on. The speed change can be orchestrated through a pedal, like a sewing machine.

Again no sanding. Dan, thanks for posting this, it is very interesting. Once the steel is cleaned up the aluminium can bolt on top to create a smoother surface for the sliding tail stock. 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). One problem here is that the old motor bearings are not taper bearings - they are not designed for anything other than small loads in a sideways direction. How would I go about mounting/using it? It's just the bearing, no cap or housing or anything. on Step 22. very very brilliant gentleman thou art!! 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. As my triac is rated at 26amps I am not too worried about it- but something to lick the heat away is needed.
