Missouri Meerscaum Freehand?

I mentioned before that I chopped an inch off mine and sealed it with elmers. It has become one of favorite pipes to smoke.

Yes. It is tall. Mine had a leak at the stem. Good otherwise.
 
Rube Goldberg lathe is a failure. Cones on the ends of the shafts do not provide enough bite, plus these heater motors came out of my buses because they were not quite up to snuff anymore. I figured they would run fine for 5 minutes or so. Not so, they are really weak. I am running them in series right now. I might try them in parallel later but I still need to get them to bite onto the workpiece.

Rewired in parallel and the speeds almost match. Added a collar on one side to add some surface area. No luck. I think the thrust load is just wearing the bronze bushings out of the motors, which opens enough of a gap for it to start slipping almost immediately.

I followed up to "added a collar" I have no idea of what your are saying, but I know you do.

Could you dumb it down for a mechanical moron.. Pics, even cartoons would be swell. :mug:
 
Having a beer and going through threads on here. Making me really want a pipe of carter hall. Think I'll pick some up tomorrow.

These motors are designed to spin a squirrel cage fan. The only real load on them is the weight of the fan, which acts perpendicular to the shaft of the motor. In either end of these motors are bronze bushings instead of bearings to center the shaft and armature inside the motor case. They are cheap but not so strong. The collar is just an aluminum handle I had and put on to hopefully add enough friction to keep in spinning.

Thanks, the picture of the collar makes that part totally clear now.

The motors look fairly heavy duty. Are they not powerful enough maintain a good RPM on the dowel(?) the part you want to spin fast so you can lathe it? <-probably the wrong word.. work with me here. :)
 
Dan said:
So the dowel is still slipping?

Very. The next step is to add some sort of studs to that collar to bite into the end. A real lathe would have a 3 or 4 jaw chuck that clamps on the outside of the workpiece.
 
Maybe add some black electrical friction tape to the collar(s). It has a very light adhesive but should stick well enough to the collar(s) and provide better friction to the dowel. Just a thought.

Sorry, I just need to go back a second...when you say "squirrel cage", what you mean is...? Pics?

It's like the type of fan found on a furnace or an evap cooler. I don't know for sure why they call them "squirrel cage". I've always thought their shape resembles a snail shell. Sorry I'm heading off to work, so no time to find a photo for you...

Oh, so disappointed. I thought you kept squirrels, and was very excited. Please, carry on.
 
Will you be using the whole length of the dowel? Conceivably, could you make a groove on either end to be sawed off later so that the lathe can "bite"?
 
I may have to smoke up a bowl of GL Pease Union Station tonight with a nice stout outside if the weather holds in the 40's or so.

Harbor freight and places have cheapish lathes... I know you get what you pay for but if all you're turning is a mouthpiece it should be fine. May be cheaper in the long run unless you have an abundance of parts around.

Ask and thou shall receive.

I will probably lose the better part of an inch on either end. I'm working on something of the sort.

Yeah, I have a HF just a few miles from the house. I'd like a real lathe but don't have the money that it takes. I haven't spent anything yet on this one. I'm gonna try to keep it that way.

Understand the cash thing! Best of luck on that project. Do you have anything available that is bigger that you could gear-down?

I have two 120VAC motors. One is a tool motor with mounting base and all. 3250 RPMs? It's what I would use if I was making something serious. I would still have to come up with a head stock with chuck and a tail stock.
 
would a rubber lined piston ring compressor work? like if you make a wooden circle, quartered it then cut a small piece out of each corner? maybe a larger chunk to fit around the shaft of the motor or am I thinking crazy? :)
 
Sounds crazy to me. Current plan is 4 (because the placement is easier than 3) pins in that aluminum collar and maybe a second aluminum collar if I can find one. It was originally an airbrake knob on an older vehicle. Of course everything now is yellow plastic.

I'm also giving thought to pulling the magnets and armature off of the tailpiece motor shaft instead of trying to drive both ends.

do you have chisels?

Depends if you mean $$$ from Klingspor or normal stuff. I do have some light and medium weight carving chisels. I think the light ones are gonna burn up on a lathe. I gotta dig the others out.
