We're gaining on the nuclear fusion. It was 50 years in the future 40 years ago.

How securely do the soft jaws need to be fastened to the hard jaws? It looks like they would just stay in place with very little help...like a hole bored into them with a neodymium magnet pressed or glued into place.

How much brass would you really need? Can you make the bushing from aluminum, then put in a wear surface on the bottom of the bushing where all the pressure is? I'd be thinking of lining it with brass shim stock.

The incoming power is always connected to the run windings. The start windings are momentarily connected to control the direction and to give the motor the initial spin up, then disconnected automatically by a governed switch internally. I think you need a double pole, double throw switch so...

That motor seems to be a "split phase" motor with a start winding and a run winding. To reverse one you would reverse the wiring to the start winding. The cover plate for the wires should have the wiring shown on it so you know which is the start winding. Here is an article about how it is...

If you cannot use the Nyloc nut a really cheap way to emulate one is to use a bit of monofilament fishing line. Just push it through the threaded hole before screwing the bolt in. Different line diameters will adjust how hard the bolt is to turn or you can use more than one line. It may need...

But, but, new calipers are so expensive. https://www.ebay.com/itm/Mitutoyo-Absolute-Digamatic-8-Digital-Caliper-500-196/253570510270?hash=item3b09faedbe:g:iz4AAOSwdIBa1~DH

WOW! What a way to disparage an entire country with only one bad example. I once bought a vehicle made in USA that turned out to be a piece of junk. Should I quit buying anything built in USA that has moving parts?

Nice mod! I did similar to my mini mill "Y" as it had no bearing and the metal to metal contact would gall.

V-belts are specified by their width, length, and the amount of power they can transmit. Measure the width of the pulleys as the belt should be just slightly proud of them when seated. Then measure the distance around the path the belt takes. Now check the rating of the motor to find the...

Chatter happens when the bit cannot make a clean cut, bends enough to relieve the stress, then springs back into the cut. You need one or more of the following. 1. Less depth of cut 2. Stouter tool 3. Less distance from the toolpost 4. Slower feed 5. Sharper tool 6. Different tool geometry I'd...

Do you ever go to a casino or buy lottery tickets? This lathe is much less risk than that. Even I would risk that amount of money for this lathe.

A good rust remover would make that lathe look much better. However, looks aren't the most important part of a lathe. Take another look at it, turn the chuck by hand and see that it turns easily and smoothly (you may have to remove belts in the headstock for this). Take along a dial indicator...

That threading shaft should turn easily. Check the bearing on the tailstock end, probably by removing it. (part 907) That part should slide off the shaft easily. Now try turning the threading shaft. If it still turns hard, keep looking for a bearing that is binding or something in the...

For some lathe work on a barrel you will want to keep the end of the barrel close to the headstock for some operations which means that the rest of it has to fit through the spindle. I think you will eventually want a lathe with a larger spindle ID. JMHO

And besides being quite expensive, except in some very specific conditions the small increments are not necessary as the strength of the thread can be nearly the same with less engagement. That is, a hole drilled a small amount bigger than optimal may yield nearly the same strength but will be...

If the thread is symmetrical it should work fine. Some may not be symmetrical.

I need one of those as I center drill a part, then pull the center drill from the chuck and put in the drill for the through hole. Then I chuck the next part, change out to a center drill, then back to the drill for the through hole. It would be nice to just pop out the MT and slip in the...

On the cover of the headstock of my mini lathe is a table showing what combination of gears it will take to make a certain thread pitch. Look for it on your lathe. If the thread pitches are listed there and are imperial (threads per inch) just use the gear combination that it shows. 5/16-18...

I think I might be in the wrong forum as I made a part for my 40HP tractor on my mini lathe.:o :rolleyes: Actually I joined because the same ideas and techniques that a model engine builder uses scale up to bigger machines too. They are also safer to learn on and you can learn with smaller...
