On Monday, things weren't looking good for my little Isle of Man test track. The boards had warped and I'd dunked them in the bath to try and fix this.
After 36 hours drying, I checked the board on a flat surface. Resut: still warped. Maybe things had improved slightly but not enough to be any use.
So, as a last attempt at fixing the problem, a length of softwood was cut to length and glued in diagonally between the corners. Plenty of weight to make the board flat again and lashings of Resin W wood glue to fix the wood were my last hope. The whole lot was left overnight.
Result: Still warped.
Would you like to guess who has been down the wood shop again ?
