Holding vice to table advice

I've never needed gauge blocks and they're expensive beasts. Unlikely ever to need them with CNC

Just looked them up... yes they are expensive!

It's 22 hours since mekanik posted the right solution, you should have had them made several times over by now

You don't use the stepped blocks like that, you would just use the one on the end set to the appropriate step height.

Hi Guys
me again
Just thought i would add before i get corrected, re stepped packing blocks.
they are actually designed to be used as a pair leaving you with a parallel surface to clamp off and so they are usually used on tall jobbies so are not really suitable for your application, was not being pedantic.

Another option would be original MiteeBite clamps, and they can be used for other work holding aswell.
They're not cheap, but they are a very versatile low profile clamping system!
50642 is the kit you'd most likely need, or you could buy a pack of just the cam clamps 50206 (come in a pack of 10) and make the other bits yourself. But having just checked the catalogue, I've just realised you can get packs of 2 t-slot clamps, which for 8mm slot is 50422.
WDS is the only online UK stockist I'm aware off, and you'll need to add '590-' in front of the mitee bite part no.s.
If you're interested and willing to wait, I'm on the process of designing a jig that'll use some of the 50206 clamps, but I won't be needing the full pack, so would be willing to sell you a couple.
.
Sticking with what you've got, you could grind/machine down the top side of the end of the clamp fingers so they fit in the vice groove. The grinding/machining doesn't have to be pretty, as long as the underside is still flat.
As a temp fix, get some longer bolts and use the clamp set to clamp on the top of the vice, be that either on top of the jaw(s) and/or on the top of the main body provided there is enough room behind the moving jaw.

Yes I know, I wouldn't use them like that either, I'd have just made some new dogs out of 10mm plate. I was trying to second guess what arc had suggested to the OP!

Well if I was you I'd remove that non-suggestion before someone tries it and get a vice in the stomach.
