Not to highjack Cadlights cool idea and post. Just thought a new one would load up a little quicker. You know how it goes with these kerosene computers. A total of three tools will be illustrated so hang in there a bit.
the first is to find top dead center The second is to scribe a line parallel to the edge on sheetmetal
[ QUOTE ] Vibration dampener installer. [/ QUOTE ] Not too bad a guess. Little small though. It's sitting on a louvered hood with typical 3" hot rod louvers that are 3/4" apart. The black color doesn't seem to blow the photo out too bad either.
1 looks like it could be a collet stop, but being that small it would fit a R8 and that would render a R8 useless. Chris
1st one A piston stop,used in m/cycles to hold the piston from moving whilst tightening the crank nuts????? 2nd one is pointing to the 3rd one and i don't know what that one is either. john just had a thought is #1 for locking the piston to set the timing????
You're right....I'm not under 25. Pic number three is a vibrating reed tachometer ("Vibra-Tak") used to measure rpm in small engines and motors. They were also used to measure rpm in ********y concrete ********s. I used to buy 'em for $5 each way back in the 70's. Still have one. You place the nose of the "pen" against the engine block, then slide the little collar up and down (moves the spring steel needle in and out). You watch for the needle to waver back and forth to its widest arc (looks like a smooth fan, it's moving so fast). Then you read the rpm's at the little sliding collar.
Number 2 is also known as a "fishtail gage".Before carbide inserts became common,it was used when grinding toolbits for cutting 60 degree threads,like UNC and UNF.Still used on the lathe for aligning tools bits for thread cutting.Number 3 looks painful.
Manyolcars hit #1 on the nose. LuckyPabst got #2 - with added info by UnklIan FortyFordGuy hit #3. Here's one more ... then the really weird stuff comes out....
[ QUOTE ] acme thread gage - used to grind acme thread cutting tools [/ QUOTE ] Luckypabst got this one as well. You guys are too smart. Or too experienced. Or something....
The wife walked in when I was looking at the first picture and wanted to know why someone was posting pictures of bolts. I explained to her that it wasn't a "bolt" it was a specialized tool that was posted to see who could identify it. She says, "I don't know about the bolt-thing but I recognize what it's sitting on. It's a broiler pan out of a kitchen stove!" ....
