Hi folks.

I was laying out the bottom and side lumber components that fit against my transom and noticed some twist on the frame bottom. The lumber twisted.. so if I clamp one side the other lifts up about 1/2". With some clamps, I can pull it back down against the transom plywood, but I am not sure thats a good idea... I don't want the transom shape got get distorted when I take off the clamps after the epoxy cures.

I can re-cut another piece, I just hate wasting the lumber. I inspected the twisted piece and the grain (quartersawn) is not quite as vertical as other pieces I have... so maybe it was just a 'bad' grain?

Its making me worry a about my other frames.. they are already epoxied together, I sure hope they don't twist either. I've not noticed anything significant so far.. but I am far from being done.

Some of you might remember, I was (and still am) very concerned about how dry it gets in my location. Plus, I am using a big forced-air heater in my garage workshop so it makes it worse. I have to heat it to let the epoxy cure.. but with this last piece of lumber twisting up (it was not when I cut it a few weeks ago, I made sure of that).. I am not sure what to do in terms of prevention.

I have about $400 in lumber still sitting uncut on wood blocks in the garage, under a tarp (so I don't drop epoxy/dirt/dust on it).. I sure hope it does not start twisting on me

Iggy,how about leaving containers of water around or a humidifier to help with humidity(or lack there of)(I'll let someone else answer about the twist....pics would be a big help)

your building form should hold things in place as you work. make sure that your boat frames are secure to your building form also. add temporary bracing where needed to any of your frames to keep things in shape. the sheer, keel and chine should help carry your frames. once the plywood skin is on, nothing will move from that point.
the lumber you have sitting should be stickered so air can circulate around it. would not cover it if indoors.

I ended up recutting a new piece.

So far the lineal lumber and completed frames still look ok.

I will be setting up my building form this weekend and will have a better look once I get everything level and plumb.

Iggy,

Also, pieces that are not so straight can be straightened out as you go. For example, my frame 2 had a good twist in it. I just worked the twist out with clamps when attaching the chine and sheer. The more stuff you add on the more ridgid it will become.
