I'm Gumby, Dam(mit)!

Posted by Chris J. on Jul 16, 2007

Sorry...my first thought at reading David�s playdoh thread.

What worked for me is to cut the dam slightly oversized and completely seal the inner side cardboard in packing tape. Hot glue a stir stick to the top edge of the dam to act as a handle for removal once the pour is cured. Wedge the dam in place then mix a stiff fillet mix and apply a good fillet around the inner edges of the dam to seal it (the long handle of a wooden spoon is a good tool for this). I know it�s tight to work around the sheerclamps but neatness doesn�t count. Give the fillet an hour to stiffen up then start the pour a few ounces at a time to avoid overheating and boil-over. Let the pour cure overnight then give the stir stick a pull and the dam will come away cleanly.
