1925 McDougall Lathe refurbish

[Duncan K]

Got the VFD and switch mounted, ran new power from the panel and got everything wired up. It sure is nice to have the speed control with the turn of a knob! The alligator clip connector for the belt makes a ton of noise coming over the top pulley. I think I might increase the diameter of that top pulley to make it a little easier on that clip to get around it. Still have to deal with that crossed screw. I'll have another go at straightening it in the press

How about replacing the belt with an endless flat belt? Transmission Supplies here in Calgary sells them (not affiliated). It would make your lathe run much smoother.

An old farmers fix (Again LOL) for baler belts with that joint that run "bouncy" over the rollers was to take two flat bars long enough & wide enough to cover the joint and then squeeze them in a big C-clamp just enough to smooth the wire bends.

My dad used to flatten the alligator clip connectors on the flat belts we had on the farm. He used a hammer and a bucking bar.

Ordered some 5/8 insert tool holders. Had to take .150 off the tool post to get them on centreline.



Made a few test cuts, so far so good. I have a new endless belt ordered from Norwesco that should quiet things down.

Almost a part of the nostalgia that clack sound. It makes the mood, Benefits of modern belt aside I would have a rivet or even paper clip in/on the thing for that rhythm but that’s me. Restomod lol

Hi Duncan! Thats cool! My first lathe was a Flather made in NH some time in the 20's or 30's it had bee converted to a giant 1hp electric motor with a fibre gear that ran on the high gear. It was quite hurt when I got it, we took it apart to get it out of the fish box plant where it was. the bed was eight feet long but after the head stock and tailstock were mounted it was 36" between centers. After a year of fixing it was a really good machine capable of excellent accuracy. High sppe was a blistering 300RPM : ) Keep on it you'll have an excellent lathe.
