Hello, I hope I have selected the correct category for this post!
I will apologize in advance if I use incorrect terminology the last time I used a lathe would be at school and we were never allowed to take those apart to understand.
I have a small old metalworking lathe that was gifted to me. It is quite old and in need of a lot of TLC of which I have started, the motor is a lovely old Hoover reversible 1HP AC motor which I have rewired with some modern cabling (adding it's reverse switch at a later date). I am in the process of cleaning up the layers of grime and re-lubricating, however I have run into a problem identifying what belts to use on it. It arrived to me without any belts or manuals so I was hoping for some help identifying what I need. It seems to be a twin belt system with one being used to bring power from the motor to the pulleys for speed changes.
I have taken measurements on the pulleys
the pulley on the motor measures as it's depth 10.6mm the gap at the top is 9.2m and the bottom is 4mm running a loop of string around them comes out at 580mm
the pulley on the main unit measures as it's depth 6mm the gap at the top is 8m and the bottom is 4mm running a loop of string around them comes out at 470mm
the pulleys on the orange arms lever forward on a pivot just behind the main unit (not visible in photographs), from that I assume I would be looking at having the belt between the machine and first pulleys actually shorter than the measured amount and the belt to the motor longer allowing the pulleys to float on the pivot rather than resting on the motor.
Although i have given the measurements in metric the machine itself is definitely imperial in construction as I have had to order up some imperial allen keys!
I also had a question about fastening the machine down to the base it is on, currently i have some loose bolts just so it doesn't slide around to much when i am cleaning parts. However the holes measure at about 7~ mm should I just get some M7 threaded bolts and nuts (with washers) to fasten it down with or should i get something in a imperial size that matches the holes exactly to minimize shifting of the machine?
Thank you in advance for any advice on this!
