Re: How to center in the 4 jaw

Unless I'm missing something here, this is a simple, straight-forward set-up. You state the top rails are 2.000 inches to the center of a 3.150 inch diameter bored hole and 1.936 to the center from the side rails. The difference between the top rails and side rails is .064. Divide by 2 and the diffe...

Re: American Model Engineering Shutting Down

Cole's closed!!! :( This is sad. I never knew Charles, But I did know Betty. Dealt with her personally when buying all the "goodies" for my Gene Allen ten wheeler back in 1981. I always pulled up in the alley behind her home in Ventura, CA and she would open up the garage door and we would make our ...

Re: Interesting things to see for folks interested in machining

If you ever get to Southern California, this museum is definitely worthy of a visit.

Re: How to clamp work....?

There is something about confession and posting a pic. This was help at some cost. Tony is not an individual you walk past thousands of. New to this, makes honest mistakes yet more to this. He probably doesn't want to take a dusty book to bed. I found that doesn't go well. When we get into complica...

Re: How to clamp work....?

Tech Tony, I'll try very hard to not sound insulting.........BUT your photo you posted yesterday told me all I needed to know about your machine "skills" or more precisely, your lack thereof. That setup you have shown shows so much. Not using the clamps in the proper way. The nut fastened down right...

Re: How to clamp work....?

I just started reading this thread this morning and some of the things that Tech Tony is doing are well.......a little dangerous in the setup. He has been lucky thus far to not have injured himself OR damaged the machine. I agree with Reggie that Tony should stop doing anything or buying anything un...

Re: Boring Head Recommendation

Think this shank will work with the criterion boring head too? That is a face mill holder and won't work with the boring head. The arbor for the boring head is an MT3 shank and a threaded shank on the other end. Steve http://1stclass.mylargescale.com/garyarmitstead/Home%20Machine%20Shop/Criterian%2...

Re: Die grinder versus pencil grinder??

I used Dumore brand electric die grinders in my trade. More powerful than air grinders and about the same rpm (~22,000). It takes two hands to control these like Pete said. At home I have a Craftsman electric die grinder (very similar to a Dumore in shape and size) and it has lasted over 30+ years w...

Re: Die grinder versus pencil grinder??

Thanks all for your replies. I didn't consider the exhaust and flying chips issue that Gary talked about. Gary, what do these exhaust hoses work? Are they like a shop vac hose connected to a blower or have some kind of external draft??? Thanks Glenn Glenn, The hose is made of very light material, b...

Re: Die grinder versus pencil grinder??

As an old timer with experience in benching and polishing forging die cavities, I would second Pete's recommendation to use a 1/4 carbide burr and a die air grinder (easy to hold in your hand and manuever in tight places). I would also highly recommend a burr with the cross hatched cutting edges and...
