That's what I figured more or less, but how will I slit the mandrel. I have no milling cpabilities. Any other "caveman type" way?

trimming length of brass bushing

What is the best trick to hold it while I face it off to the correct length? It has a flange on it to compound the matter. Couldn't get one stock in the right length.

big hunk of cutting steel

I acquired a large hunk of cutting steel. It's an old paper cutter knife. The grinding service had claimed these were made of hss. I think they were incorrect. I cut a small piece off with a chopsaw and it is just barely cuttable with a hacksaw. I then took it and heated/quenched it in oil and it be...

this is why I posted the question. I had the feeling that brass was a different animal. After all, it's used for bearings in combination with steel shafts, so it must have some "tough " properties. I will use the old sawsall and patience.

:D Harold, why didn't you tell him about using a ball as from ball bearings to engage the center? That allows rotation without distortion. Whoa....I still get mildly "willied" when the piece starts rotating with points. I can see myself doing something wrong and the bearing coming off while the dog...

turning between centers, tapers

How deep should I be center drilling the stock when turning between centers? What kind of results should I expect when turning tapers by offsetting the tailstock center? Also is there a limit on speed when turning between centers? Oh,... and can one remove a threading job from the lathe when using l...

Air hardening tool steel

I just turned some of this on my little 6". Is this stuff alway this nice to work with? I have turned 4140 dead soft,stainless, mild steel,drill rods,etc, but this stuff had the best finish I've ever managed. I don't have much experience so maybe it was just luck. Seems hard to get ahold of in round...

I agree that there is a right tool for the job. One thing my saw has set up on it is a crosscut sled with zero clearance. Since making that jig I don't even use the factory throat plate unless there is no other option. It is far safer for small pieces of wood too, and much more accurate. Bad things ...

I figured that is was "different" than aluminum. That's why I posted. Even the aluminum I tried gave me the willies with the metal chips all over and such. I'll just use a sawsall on it. Not really that much cutting anyway. Some things do cut what they're not really made for. I have had to cut hundr...

cutting brass/ table saw?

I have some old hunks of brass. They are about 1x3x20. I'd like to turn some stuff out of them. I have cut aluminum on my table saw and it worked fine. Will the brass also cut OK? I want to make the dimensions more square, so the I don't wast so much of it.

If you have no thread dial (or if like I was yesterday, your cutting a metric thread on a imperial machine so the thread dial doesn't read true), *AND* you have no reverse, you can always wind the chuck backwards by hand after each cut manually leaving everything engaged. Its hard going physical ef...

Just keep in mind that no matter what you do to the bearings/chuck/arbor, etc, if the whole unit flexes badly under cutting pressure, if won't change a thing.
