Spring Clamps for Board Repair

I’m putting back together a partially detached nose on your standard PU board (hanging on by the deck glassing). I’m planning on using the gorilla glue trick. I don’t have any clamps to hold the board together while it dries. I went to the hardware store to pick up a couple spring clamps (based on what I’ve read here). I was checking out their strength and it really felt like the clamp would crush a standard PU board and cause damage. Am I looking at the right thing?

 

The ones I was checking out looks like these:

Alternatives? Will it not crush? 

Thanks.

OceanKyle, if you look at the original photo, you'll see he has two strips of wood that the clamps are bearing on. Never clamp directly on the work surface. Always use a sacrificial block in between. The pressure it takes to clamp tight will damage the material so a piece of wood or something else is required.

Adjustable.

Thanks. Little more expensive than I was hoping but better than crushing the board haha

Try this then,

 Cut some plywood scraps with a slot just a little bigger then you need and then use beveled wood shims to close the gap.

Savvy? 

That’s why I keep coming back haha

Use the wooden board builders trick…a section of 4" PVC pipe with a saw kerf cut into it.
