I need to do some frame repairs, a want to construct an inexpensive surface plate. It only needs to be frame sized, so I was thinking of using a 4x8 sheet of Melamine, shimmed with floor tiles. But I'm not sure if this material is straight enough for my needs. I could also us 1/8" or 1/4" steel plate. Thoughts & suggestions ?
Related question: what are the odds of replacing much of the bottom frame rails on an RF80 without it ending up like a pretzel ? The chassis tube are built up from these lower rails, so it doesn't look I can just un-braze and replace them, because you can't access the underlying joints.
Thanks,
Steve
