i have to braze up a that little bracket for the back gear, and maybe take the spindle apart, it seems to lock up the whole thing when i engage the back gear
Lots of potential there nice find!
Don't forget about the pin on the bull gear

haha yea i just found that.....works fine now! lol
i was running it by hand anyhow, its still sitting on the trailer out on the front street while i do other less enjoyable things
Looks good, AXA tool post will work well for your machine.That's an interesting pulley setup.
Yea I've gotta sort that pulley mess out at some time, I haven't quite decided what the solution is going to be there
? I see a motor with pulley in his first image?
So what's wrong with that?
The countershaft and motor pulleys are sized so that when you change from one set of pulleys to the other set the belt tension stays the same. If the pulleys aren't matched you would need a different size belt, or re-tension the belt, every time you changed pulleys. So a two step pulley on the countershaft and a four step pulley on the motor will probably need to have the belt changed or re-tensioned every time you do a pulley change.
It looks like the motor is on a piano hinge. If there is enough weight/travel, the tension may be constant, just the motor position will be different. Maybe there is a spring to assist with the tension? - can’t tell from the picture. It does look like the belt runs at an angle, depending what pulley position it is in. Could cause excessive belt wear or the belt to jump out of the pulley. But may all be OK for this low power application.
There is more to it than just the motor pulleys being wrong, unfortunately the driven pulleys on the countershaft have been changed to standard v belt pulleys for some unknown reason
my options are to make or have made the proper drive and driven pulleys, find some on ebay, or make a simple/quick belt tension system so that i can change from the large to the small driven pulleys, as with it on the same drive pulley changing between the two driven pulleys yeilds close to the proper rpm on the counter shaft (300/600, it gives me 342/600)

correct, it is on a piano hinge....its been bodged pretty good, but what can a guy expect for something that has been used for 80 years, someone with less than stellar skills was bound to get on a repair at some point
