Can a small granite surface plate be used as a square?

A square what?

I believe you can buy such a thing...

 

[daxliniere]

Granite squares are available.

Yes, but over £100 for something I'm going to use only a few times, it's a bit rich. For an engineering shop producing parts to other people's specs; yep, absolutely. Worth spending even more, I'd say.

I was hoping I could pick up a small used surface plate (<300mm) for cheap, but that's good to know about sides not being lapped square. Thanks for the heads-up, Brad.

Cylinder square might be a more cost effective option. I don't know how true that may be (no pun intended) but it occurs to me they might be easier to produce.

@daxliniere It won't help your cause in relation to a sqaure but I do have a small granite surface plate going cheapish round in Ilford as part of project clear out

Don’t assume it’s square!
It’s a surface plate not a square so edges are not going to be very square, or co plainer

Buy a granite tile from wickes... it'll be as square as half the squares that are for sale these day.
Or buy a square....

Thank you, everyone!

Thanks for the heads-up, Milkybars, but I'm good for now.

Old piston pins are great for many applications ,I found myself using them(35mm diameter x 100mm long) for setting up things on machines .
They are precision ground on the flat surfaces too + they are hard as hell but they still not brittle since we use on the hydraulic press too

Sounds like a great idea. You'd really want a great big one though!

If you have the imagination it can be anything you would like it to be…..
