View Full Version : Replace Intermediate frames on cold molded bottom?

Hey guys. I previously posted about the restoration of my 1950 Chris Craft. Im in the process now of removing the bottom planking to get at the frames, keel and other structure that need repair. (pics at the end). I am replacing the planked bottom with a cold molded plywood bottom. I am wondering if I need to replace/return the intermediate frames. I think the old ones were just there for a place to fasten plank ends between the major frames and I suppose some added stength to the planks. They do not attach to the keel or keelson. Since the plywood is much more stable than the planking, are the intermediate frames needed? My guess is no. An added note--this is going to take a whole lot longer than I thought and be more expensive. Almost everywhere I look in the bilge there is something that need to be repaired or replaced. Its going to be a combination of replacing, scarfing, sistering and a lot of cleaning up and painting.

Yes, I know many think I should replank but this is how I want to do it--I'm familiar with the points of the debate.

The exposed frames look worse than they are but there are some that will need replacing or sistering, a lot of cleaning, sanding and repainting. http://i571.photobucket.com/albums/ss151/cmeke0870/work%20begins/100_0128.jpg

Well, I think I have reversed course. I can't see what it would hurt--except the extra time--to return/repair/replace the intermediate frames. Unless you had a lot of experience, or were an NA, you probably couldn't say it is okay to leave them out. Still, I am guessing they are largely superfluous on a cold-molded bottom.
