Can anyone identify what thread type this is? ACME I assume? It's from a piece of denture equipment, it is brass. It is stuck tight. Questions: 1. Is there a properly priced thread-pitch-gauge out there for ACME threads (non-china)? 2. Is there a source of fairly priced taps/dies for cutting...

As an alternative to the traditional metal/pvc culverts, what about large plastic drum/barrels connected end-to-end? Question(s) would be: Would they be able withstand the pressures (depth considered)? Is there a good way to connect them to prevent leakage (maybe some kind of adhesive...

These: I have a 20" "Disston & Sons" straight-back saw I got at a yard-sale and the local antique shop has large miter contraption similar to the picture above with a large, low-TPI saw to go with it (I think it is a Stanley). I'm thinking of buying it. Are these things pretty accurate...

Anyone have a good source for non-china wire brushes (Nylon, SS, Steal, Brass), hand and wheel types?

Hi, I am looking for high-quality, but not ridiculously priced, precision tools. Preferably certified. For starters I'm thinking: Grade-A Granite Surface Plate (18x24) Straight-edge (12") Straight-edge (24") Thread rules: No Starrett or Snap-On please.

First, found this on CR for $500. Onan, 15WK. Watcha' think? Second, can anyone tell me about propane generators? Here's a thread for it. Thanks.

When is a socket too large, or too small, for a drive size? Where are the official tables/charts and math for deciding when to move up or down on a size? Ex: I have a 28mm socket that is for a 1/2"dr. That seems a little too small a drive size to me. Idk. Thanks.

I can't remove the spindle, it is caught on something. Like this: http://www.chaski.org/homemachinist/viewtopic.php?t=93679 Anyone have any ideas on how to disassemble one of these? (It's not a ratchet-type) Thx.

What sizes do these metal storage trays come in? I've seen 18" but do they come in larger (say 20")? (BTW, what exactly are these called?) Any reason a setup like this wouldn't work for tool storage, as an alternative to a tool chest? Thanks.

My OCD requires me to get a -SK- 7mm 1/4"dr Deep Socket - 6pt that I am missing. The new ones are about 50% overpriced IMO. I'm looking for a used one. Just throwing this out there, S&H may not even make it possible. Thanks.

I saw Mattblast's thread on Sticker Reproduction (very cool), and I have been wanting to try etching (think: Maker's marks, nameplates). So here is a thread for it. Examples (metal): Logos for blades, tools, PCB boards, nameplates, jewelry, printmaking, etc.. There are other material...

Hi. I have a couple questions I have to ask: 1. Are Japanese (perhaps older) sockets and ratchets any good? I heard rumor that they aren't very strong. 2. There is a Proto Breaker Bar - 1/2" (used) nearby for $15. Good deal? How do Proto Breaker Bars hold up? Thank you!

Just what the title says. I have a 14lb sledge head that does not have a handle. Can you recommend a length/brand/source? Thanks you.

Kennedy Boxes (Machinist Boxes) Thread Has there been a thread about machinist tool boxes, such as Kennedy boxes? I got a Kennedy box in gorgeous condition at a yard-sale for $5 (pic), and have decided it will probably be used for parts.. (click for larger) But it brings up the question of...

I need a large Crescent Wrench. I may be able to get one of these for $10. In comparison to modern "Crescent" wrenches, what are the pro/cons? This old beast with thicker jaws looks like it could work a nut very well.. unless the steel is too soft, it won't fit right, or they were known to break...
