It's been a while, but I'm slowly getting this bed repair done. Picture below is of a section that I put in to replace a rusted part of the original sill, where the carriage bolt comes through. I used a decent piece from the original bed for the repair. I still wonder if simply butt welding the section in will be strong enough. Can anybody provide an informed opinion as to how I should finish this type of repair? Should I reinforce somehow (how?), or will it be strong enough as is? Thanks for any help. - mark
