I know that you don't need to clamp with epoxy.
But my question is will it hurt?

For what i'm doing it will be helpful if I can use some spring clamps to secure the wood in place so it doesn't move while the epoxy is setting.

Here's the style of clamp i'm talking about.

Would this put too much pressure on the epoxy joint?


Edit*
Oh well, I can't seem to get the pic to post.

I could have made 16 sanding blocks by the time you thought about it. Yes you can use spring clamps if the jaws will open enough. And, no, there won't be too much pressure on the joint. If you properly mix your epoxy, you may not have enough time to clamp it, so be fast and be accurate.

The spring clamps were just bit too small.
So I just epoxied it, and wrapped it with blue masking tape.

I wish I had drilled the small holes so I could have snugged it up with wood screws though.
This thing was wanting to swim around, so I had to baby sit it for nearly two hours.

I used 60 minute Loctite epoxy, and applied it to both surfaces per instructions.
But i've got a good ounce and a half of epoxy in there, so i'm going to let it sit for a good week to harden.

The main problem I think, is that the rough side of the granite is so porous, that it just drank up the epoxy.
I was lucky I went with two kits, or I wouldn't have had enough.
