![]() I also don’t have any end mills to make the slots or recesses in the mounting brackets so I sketched up the brackets and emailed them to a machinist friend of mine to make them for me. The back of this lathe is different than Bill’s so I plan on mounting a bracket on the bottom similar to the top one. I think I'll order a belt so I'll have it on hand before I put on the mounting brackets. I taped up some speaker wire the approximate size of a belt to see how it would fit. I can’t move it by hand so I might just leave it without epoxying it.Īfter checking the sizes of belts available at McMaster-Carr, I decided it was a good idea to see what might work. I must of lucked out sizing the pulley to my hand-wheel, as it was a pressed fit. The MXL pulley was solid plastic and cut nicely. So I decided to position the pulley on the wheel. I think the new model lathe has a slightly different hand-wheel than Bill’s has, as it didn’t seem like I would be able to thread it on enough with the addition of the pulley. I drilled out the aluminum insert on the 130 tooth one and mounted it in a chuck to make it fit my lathe. The source that had the larger pulley didn’t have 20 tooth one with a ¼†hole and I didn’t want to buy from two places and pay shipping twice. The small MXL pulley needed to be drilled out slightly to fit the shaft. I had a small plastic electrical box and a piece of plastic (HDPE?) to mount and protect the control module. Here are both plugs completed and connected to controller per instructions provided by Bill Ooms website. ![]() I think next time it will help if I will drink less coffee before hand. The alligator clips sure helped to solder the pins on the wires. I used some plastic tubing that I had to protect the wire I think it was medical oxygen tubing. The leads from the stepper motor were long enough that I cut them in half and soldered the pins for the Molex connector on the motor leads and then six for the controller. Here are some pictures of what I done so far. Rummaging through parts I have, I found a 5v 1a power supply and a cover. The controller and MXL pulleys are from the sources Bill Ooms lists on his website. I got a couple of Molex connectors from Ebay also. As previously mentioned I bought a stepper motor on Ebay. This gave me another reason to get a midi lathe, so I took advantage of the recent Jet sale and bought a 1221vs. I’ve made some progress on this project. You can't run software that you buy from someone else.Īnyone who is actively building some hardware can email me directly for additional thoughts and comments. Furthermore, on Apple tablets and phones you can only run software that you buy through Apple's store. The Bluetooth/Arduino idea is probably beyond the average woodturner's ability to get working. There are only a few newer tablets that have that capability. Yes, there is a USB charger connection, but you generally can't connect some external device (like a printer or a USB thumb drive) to that port. You need some kind of output from the tablet to drive the electronics. I've considered running the software from a tablet (or smart phone), however the main issue is that on most tablets there is no USB output. I recently "upgraded" my shop computer to a used (but newer) Mac Mini that I bought on eBay for around $350. Our local Habitat for Humanity ReStore sells old refurbished computers for around $50 (including a flat screen monitor). There is no good reason to avoid putting a computer in your shop.
