Help with V-Block identification (huge blocks)

[Farrell]

Hi everyone,

Today I stumbled upon the largest v-block set that I have ever seen. I honestly thought they were much smaller buying them without knowing the dimensions.

The vblocks are
14” wide
10” tall
4” deep

I honestly will never work with anything requiring blocks of this size.

The reason for my post is that I would like to learn more about them. I do not see any brand markings on them.

Any advice as far as brand, material they are made of or application would interest me.

I am located in metro Detroit if anyone is interested in them.

Thank you

-Between these two statements it sounds like you're just wanting info to put in the "For Sale" ad.

Could be shop made or a Chi-Wan import, hard to tell from the photos. I've worked in a few shops that had the capability to make them and have seen a few that were shop made. Biggest factors affecting price would be:

1) The material used,
2) Whether they're hardened or soft,
3) Whether the surfaces are ground or milled,
4) Whether they're truly a matched pair,
5) The accuracy of the "V".

There's a few things that could determine/answer the above listed factors but you'd have to know more than the average merchandise flipper. Overall design is not very well thought out for machine shop tooling IMO.

V-Blocks are often an apprentice-made project for machinists in training. They're also often made for specific purposes/jobs. I'm not saying that's what these are for sure, but if there are no brand markings/stamping anywhere, it's likely they're shop made.

Some automotive cylinder boring machines use similar V-block cradles.
