What is a "1-2-3 block"?

It's the hardened steel block shown in the pic in the first post. Precision ground square and parallel. Laid flat is 1.000" high, on edge is 2.000" high, and on end 3.000" high. The holes allow them to be bolted to fixtures, or each other to make custom setups.

You can probably guess about 2-4-6 blocks....

It is a block of extremely hard steel that is exactly 1 inch thick, 2 inches wide and 3 inches long. The faces are machined to be exactly 90 degrees from each other. Most, like mine in the picture, have holes (some threaded, some not) so you can bolt them together to make simple setup jigs on the fly. Metal workers have used them for hundreds of years for setting up their toolings. Using them the way I am, in the wood shop is less common, but you get your machines absolutely dead-nuts square. They cannot be beat for speed and accuracy.

It’s always good to have good neighbors.

We must have been typing at about the same time...

Great minds think alike!
