Yeah I looked at the motor and the only part that was left was one piece of plastic held by the washer and nut :lol: Then I was like... where the heck did it all go... I find pieces scattered all over my garage, and I saw the one piece embedded way in the wall and that's when I realized how bad it could have been. Thought about it all day.

So what are you going to replace the chuck with? Something made of metal I hope :wink:

If I were you, I'd see if someone on the forum could machine one for you out of aluminium.

I was trying not to spend too much on this but if it boils down to me needing a custom part I'll be more than willing to getting one. I'm a little freaked out about it now. I need a dial switch so I can keep the power low.

You could add weight to the chuck, might slow it down sufficiently. I think if you want this to work reasonably well, a machined chuck is a good place to start. If you make one yourself that is slightly off-centre, the lathe might not work at all.

What are you going to use for the lathe tools? Is the carriage tool thingy (don't know my lathes very well) going to slide along the bed manually or you going to add some wheel thingy or something?

Just curious, sounds like a cool project :)

The bed (don't know the term either :D ) if controlled precisely by a threaded rod and a wheel turned by hand. You can see it kinda in this picture.
Image
The sled bed thing is centered and stabilized by the two other threaded rods.

Adding weight slows down the acceleration, but once it gets up to speed it would have way more energy, am I correct? This is an insanely strong motor.

For tools, I was going to use homemade tools and wood chisels (sharpened screw drivers :D ). The bed sled thing will have attachments to hold some types of tools and there will also be a tool rest to use chisels by hand.

BTW I haven't made the sled yet but I know how it will be made. Wood body most likely, aluminum tubes to slide on the outer threaded rods and nuts or nut couplers in the middle to grip the length control rod (I don't know any specific terms lolol :lol: ).

I'm going to go out on a limb here and say that wood is not NEARLY ridged enough for a lathe bed.

I will concur with Ramses, just buy a Sherline. But if you insist I would just use angle iron welded appropriately.

And get a copy of Dave Gingery's books on building a lathe at home, I don't know if you'd be happy to cast the lathe bed and other parts, considering what just happened.

Good thinking with the chuck though. But don't use plastic for big spinny thingies anymore, we may dig at you, but we don't need you full of PVC shrapnel.

Off off topic, I think I've just perfected the diaphram valve, so far I've taken it to 240PSI, and once I get my compressor fixed up, I'll take it past 300PSI.

It has the flow of a piston valve, and is so simple to maintain. And a little suprise for JSR. Expect a topic in a week or so, need more research.

I've seen a whole bunch of homemade lathes with wood beds.

Zeus... If I had 2 grand for a Sherline don't you think I'd have one already :wink:

Unless I've misread, you'd trade your bollocks for a Sherline lathe? My my, the foolishness of youth.

And a little link for you all, once you figure it out don't give away the answer please. I want to know I'm keeping people awake at night.

The motor is 120V? Could try a router speed control...harbour freight may have a less expensive one.

Don't be put off...keep after it. Doesn't take much to turn wood or plastics.

Having electricity, you're miles ahead of this fellow...and look what he does.. :)
