Re: Live chat room for home metal working??? Marty

I set up an IRC server at work for internal tech use and set up a java-based irc client to work with it. Works very well and get nothing but compliments on it. The java client can be downloaded at http://pjirc.com. It'd have to be run on a web server obviously, but is a heck of a lot better than mos...

Re: Gas axe soot

I was under the impression that turning off the acetylene first could conceivably cause a burn-back ( or whatever the term is ) although I've never experienced it myself. I usually just have the acetylene on enough so that when it lights, there's almost no soot.

Re: That's no Atlas lathe!

How about http://www.machineryvalues.com/details. ... eNo=127385

Poreba made a huge lathe as well. Didn't have a normal lathe bed per se, and you stacked hube plates under the head and tail stocks depending on how big the part was you wanted to turn. It was huge.

Re: Threading Between Centers

A dog should have no trouble holding the piece while you thread it. A dog can hold a part while you turn 1/2" off of it at a time if it's bolted down correctly. They have plenty of holding power.

Re: Need gasket removal hints

For cleaning up ferrous (steel/iron) gasket surfaces, not much can beat 3M Roloc disks. Put one in a high speed drill or die grinder and the job is done in no time. I haven't used 'em on aluminum though. The one's I use are pretty aggressive and would probably remove the base metal pretty quick.

Re: Audi 20/Valve head

The Yamaha Genesis motorcycle engine was renowned for the power it made with a four cylinder configuration and five valves per cylinder. Honda made the limited edition NR750 motorcycle that ran four oval piston cylinders and eight valves per cylinder. Cylinder block with pistons: http://www.netoubli...

Re: pixels

"Resolution" when relating to computer monitors can mean different things to different people. Most folks see a resolution like 1024X768 as being the viewable area on a screen. The old standard for scanning photo's and posting them to the web was 72dpi. Most PC's these days will display at 96dpi. So...

Re: Tig cooler pump

I'd imagine you could use a small inline pump as used on small fountains. Not very high pressure, but plenty of volume. Possibly set it up with a large aluminum auto-tranny cooler and some sort of small water tank. Would probably work well. You'd want some sort of additive in the water as well. I've...

Re: Info and ?? on the Lincoln MIG welders

After thinking about it more, I think I confused a small Hobart MIG machine with the Lincoln unit. The small 135A Hobart machine had a plastic drive system. I don't think I looked at the Lincoln unit after all.

Re: Input about new forum

I guess I'm just the opposite from you guys. I found the previous format difficult to read because everything was just mashed together. I think the current format has far too many categories, but it's much easier to use in that I can go to the category I'm interested in and just ignore the others.

Re: Atlas Shapers

Have a look at Atlas shaper

A shaper removes metal one stroke at a time. If you look at the picture it's pretty self explanatory. The shaper functions like a knife, peeling off the metal as it goes.

Shapers come up for sale on ebay pretty frequently.
