That's using the lowest an highest of the 3 belt driven gears.Īlso, I have lubricated and got the broken gear sliding and selecting correctly and got the powerfeed and lead screw turning. With a 1400RPM motor and allowing the VFD to do 25% to 115% of rated motor speed, that should give me a range of around 80-1300 RPM at the chuck. He's going to come and have a look on Wednesday. I have a mate who is a genius with electrics, and I'll probably replace the motor with a VFD. But there isn't any shaft etc at all present.

There will be a lot of cleaning involved in this one.Įw, I figure the same re: the back gears. I have Thing1 (13 years old) and Thing2 (7 years old) giving me a hand.īack of apron (Small).jpg top of apron (Small).jpg ways (Small).jpg I'm looking forward to working out more of the puzzle and cleaning pieces up tomorrow. Have yet to measure or work out if there is any way to adjust any of it. I may get a reduction using swappable/reduction pulleys from the electric motor when I get one.Ĥ) There is a second gear on the outside end of the gearbox (lowest gears at the geartrain end of the lathe in the photo) that doesn't seem to be used for anything.Īny ideas what this is for? I'm not sure it's supposed to be there.ĥ) A fair amount of backlash exists in most places to my completely untrained eye. Gearbox (Small).jpg spot weld (Small).jpg drive shaft (Small).jpgģ) Back gears are missing completely, hence I will only have the 3 speeds at the moment. If anyone with a similar machine (I know there aren't many around) could give me an idea or a photo of what should be there, I would greatly appreciate it. The gears attached to the end of the leadscrew and drive shaft are not spaced/shimmed correctly at all and the castellated nuts are at the end of the available thread. Then it won't need to be tak welded, and would engaged both of the gears driving the powerfeed and lead screw. It looks to me like the gear needs to be longer to take up the rest of the length of the shaft. I have yet to sit down and work out if that gear is long enough, original, needs to be welded there, and how that drives the powerfeed shaft and/or the leadscrew. I can see a final gear in the gearbox with a missing tooth and some mig tack welds. So I don't know what is missing, or if he has assembled it correctly.Ģ) I was told the powerfeed didn't work. My difficulty is that the previous owners received the lathe in bits and put it together (loosely). I've started to look at the condition of it, but haven't had too much time to digest or figure out exactly what will be required to get it running to a reasonable standard. Hopefully it will provide some reference material to others wanting to know how these go together once I've sorted it out. I will take a heap of photos during the process. As promised from my welcome thread, some pics of the MARS lathe.
