I picked up a new frame from a member last year. I am now getting it ready to be galvanized.
The frame is relatively clean and is rot free. However, I know the crossmembers on these things are known to rot. What should I do to test a crossmember that looks solid? Should I cut a hole in the top and look inside? I can then reweld the plate back on.
Should I add drainage holes?
I am curious to hear your thoughts. I want to do this once, and right.

Re: Frame Crossmember
The front cross member should already have a drain hole in it. It really depends on what conditions the vehicle has been driven in before it's a concern. The water and debris can only enter from the side frame rails. If the rest of the frame looks solid, it's up to you what your approach should be.
Beyond any hope for intervention
