A great conversation piece to have on the wall among your other charts, but Tracy Tools Ltd. can't take credit for that one, its been around since the early 1990's. My friend had one framed in his gun shop, and would show the occasional DIY customer a potential fix for their miscalculations, lol.

I have seen an actual display of bolts made like this.  Advertising for a hardware distributor.

   


This has been around for many years.  Dad gave me a hand drawn copy back when I was in high school, so sometime in the mid 1970's.
Full of ideas, but slow to produce parts

Thanks Roger. Now I have another project on the list. :)
I've seen many variations of the poster, but never the real thing.

The HAYES board would be a cool item for any shop, I like it.

I first saw the "chart" in the Mississippi State University engineering dept machining & fab lab.  Tried W/O success to find one for quite some time then ran across it yesterday purely by happenstance.
