Default RE: Clamping help


ORIGINAL: jmurphy18

Folks
I did my 1st clamping of the Horz stab parts last night. I am using some small bessy clamps but they are leaving marks in the wood! I tried popsicle sticks same result. Any suggestions.
I will attach a photo, marks at the bottom are from plastic closepins. I am using titebond II. What do you folks do to avoid this???

I cannot seem to upload a photo, jpg file@375K
I placed the shot on my homepage

Thanks

I had a look at the pic of your bits and the clamp. I have a number of those clamps and wouldn't dream of using them on balsa, they are far too strong. If you are laminating bits you might try pinning them (short pins) over a polystyrene ceiling tile and weighing them down with books.

Another clamp I have used is a plastics molded clamp with a rubber band to provide the pressure, this is of course adjustable.

You can try ply pads under any clamp with the edge of the ply sanded to a small radius.

You may be able to steam out the dents with a LOCAL application of steam.
