The Real Lathe Pt. 3: Make a Countershaft
Added 2018-10-26 23:30:51 +0000 UTCFriends:
This week has been a blur. Working out all the technical details for a full-size lathe is a big challenge and there are SO many details to keep track of.
Still, the work goes on and I'm delighted to bring you Part 3 in the Real Lathe project. In this video, I'll show you how to get 8 or more speeds out of a single AC motor. By building a countershaft, you can take control of both speed and torque and get the speeds you need from the motor you have.
Best of all, this project is VERY low cost. I pretty much built it out of shop scraps. It takes some time and ingenuity, but it's a very doable project for the DIY craftsperson.
I hope you enjoy this installment. Next time, it's off to the tool rest.
Enjoy your weekend!

Fascinating! I had no idea big, brushed motors were so common in Europe. The only brushed motors I have are in smaller, older tools. Glad you liked the video!

2018-10-27 19:59:58 +0000 UTCexcellent video! actually, in Europe, most common AC motors (that you salvage from home appliances like dishwashers and washing machines) are Universal, brushed motors. they are very common and easily speed-controlled (any triac-based dimmer will do). the downside is that they aren't sealed (usually), very noisy and use brushes. The best option is to salvage a motor from an old power tool, but these aren't as common in dumpsters as washing machines.. :)
