hi, thought id share with you this little project. this lathe belonged to my stepdads uncle, he doesn't know a huge about about it and most of the info i could find is here...
http://www.lathes.co.uk/zyto/
although it is probably getting on for 60/70 years old its a solid piece of kit, and produced surprisingly good results when i had it running (considering the issues below) so i think its worth putting a bit of effort into getting it up together.
it came with a collet chuck + a LOAD of different collets, a standard 3 jaw chuck, a 4 jaw and a 3 jaw independent, plus a box full of tail stock chucks/centres etc...
i did have this bad boy running briefly at one point, but the motor i had eventually gave up the ghost and i put it to the back of my mind as it was not a priority.
anyway me and my step dad have for the last couple of years gone to the model engineering exhibition at Alexandra palace, which has inspired me to get it going (for the least financial input possible)
i do have all of the gears/parts for thread cutting but to be honest id like to keep it simple for the minute so they will stay nestled in their boxes for now.
i may have just acquired a treadmill with a 2HP motor (plus speed control) for a the princely sum of 10 pounds sterling.
the old bearings and spindle are a tad f@#!ed to say the least (see photos).
The lowest point on the spindle is 25.19mm in the lowest groove, so i thought if i have the spindle turned/ground down to bang on 25.0mm and get a pair of oilite bearings machined to fit that should do the trick, or am i being naive in thinking its that easy?
i'm going to do away with the 3 step pulley system in favor of a toothed belt system between the spindle + counter shaft.
The original bearings are 28.65mm OD, the left is 34.77 long and the right (nearest chuck) is 37.86.
the plan was to get a pair of plain oilite bearings 30.0mm OD, 40.0mm long with a 25.0 or smaller ID and have them turned down to the correct OD, parted off to the correct length and bored to fit the spindle.
would they need boring/aligning once installed into the headstock?
i will do my best to keep this up to date as the project progresses, and will get some better pics next time i get out to my workshop.
cheers,
josh.
