twisted outrigger hull

[morewattsnow]

I built an outrigger hull for use with some JAE sponsons I have. The 1/8"plywood I used had a pretty good warp to it but I figured what the heck, I'll try it. With just the sides, transom and bulkheads glued together (I use a jig made from a melamine shelf and some angle iron) it's twisted- left front and right rear are raised about 1/4" when sitting on a flat surface. No top deck yet. Anyone have any ideas on how to correct this? I kind of figured this might happen, but I already owned the wood so I figured I'd give it a try. Any help appreciated- Thanks,

When you build a rigger you must need a good jig that is very simple to make: a hard piece of wood and two aluminium angles.Place sides and bulkheads on it and start gluying parts ensuring everything is right angled.After that glue the bottom and wait it final set before remove it from the jig...this way you always will have good tubs that are a must to have a rigger runs well.Gill

If you have a jig like pictured:

Soak the wood in hot water for 1/2 hr, change the water as needed to keep it hot. Take boat out and quickly get it into the jig and clamp her down. Let it sit for a few days.

I flatened out some plywood with this method. Granted its not a glued together tub, but same concept should work.

Another way is to steam it. Clamp it too a nice flat peice & either use a hand steam cleaner like a steam mop attachment or use an electric kettle/jug with a spout & hold the tub upside down over the steam moving from front to back over the entire area. Super heated steam will help mould / relax the ply tothe shape you want. This is how we used to make the curved up nose when we made water skiis. Wear some good gloves or keep you hands away from the syeam as you will get burnt. A steam burn is a third degree burn & extremely painfull .
