Hi Bob,

I like your way of bending the sides. I started a Polly Wog a while back, and the sides didn't bend evenly, so I have to start over, and this time I'll use your brick trick.

I don't think my brick method will work just by itself.  I have built three Poly Wog hulls and I started by getting the wooden sides wet with boiling water then using the bricks the leave it for a couple of days and did the same again but the hull has a very tight hull and the only way I managed to bend it was over a sauce pan of water and slowly bring the ends together using a strong cord.  This is best done when the domestic authorities are elsewhere. On the commercially produced Boucher Polly Wog the side were cut as curves and the was no centre frame, it was the Popular Mechanics version that had one.  I did a thread on making one of mine at:

Take care.
