Crack attacker

I had a look at my friend's Ohana which had gotten a crack in its'
spruce top. It was below the bridge and my longest tiny clamp could
just reach the little caul's closest end. So I made a hinged strut
with a long handle and attached it to the caul. Mending patch was
stuck to the caul by winding tape with the sticky side out around the
caul, and the clamp was superglued to it. After getting the clamp
fastened I could push the handle to raise the strut, making it push
the patch up against the top.

The mock-up in the pic is an attempt to show it, I don't have a uke
split on the bandsaw yet.
