This might be considered fringe woodworking but never the less the end product is wood. Wood pulleys are difficult to make because they are hard to hang onto. This device makes it very easy to make an accurate pulley with a good margin of safety. That is, if you have a metal lathe.

Here’s a video: https://youtu.be/mgs21_DBxFU

PS These pulleys are for a Wimshurst Machine, a static electricity generator. If this sparks and interest I have two machines posted in my projects.

Never tried it on my metal lathe, but I do make a lot of rotors, wheels, gear blanks and pulleys on the wood lathe in a similar fashion. I have several different sized mandrels I made, depending on the axle size needed. Just a simple threaded wood faceplate that screws directly onto the spindle. Through-bolt sized depending on axle bore needed. Here is a rotor I made on one to replace a broken rotor on an old Delta scroll saw:

Didn’t cost anything, and does the job fine – but yours looks WAY more impressive :)

Cheers,
Brad

Hello Brad. I’ve done the same on my wood lathe but occasionally had problems with the wood slipping plus I wanted a smaller hole. I even rigged up a router to shape the pulley. It worked well although not a smooth as i though it would be. I was going to put holes in these pulleys anyway so I thought, why not use them to drive the disk? The metal lathe is great for accuracy and repeatably. Also smooth as silk. I ground the tool with a huge rake angle so is shears instead of scrapes.

Very handy tool. My grandfather use to make pullies on a drill press, I’ll bet that was a trick.
