Topic: question regarding spreader plates over uneven floor
In order to make sure our cage builder produces a lemons-approved cage, we have a question about how to handle a deep wiring channel that runs directly under where our A pillar downtubes will terminate. Many have recommended pounding the floor board up to be flat with the rest of the floor, however we have fuel lines on the bottom of the passenger side which secure to the bottom of the channel. I suppose we could rig something up to keep them supported. We are interested, however in perhaps another option. The rules say that the spreader plates cannot have air gaps under them (or breaks in the welds across these gaps is inferred). However, what if we take a much larger plate, say 10"x12", and bend 2" of the short side 90% to weld to the door sill, then have 2" cross the channel, and have the remaining 10"x8" welded (on the three sides on the long side of the gap) to the floor. This gives 80 square inches of spreader plate on firm floorboard, but those 80" would only be welded on 3 sides. The fourth side weld would actually be 2"x10" welded on three sides of the 90% vertical on the sill. Does that make sense? Additionally, if necessary, we could build gussets shaped like the channel in order to keep a continues weld all the way around the 10"x12", but we would technically still have the air gap underneath. Our welder is capable of doing either of these, but we just want to see if it would pass. Perhaps it's just best to mash the channel up to meet the rest of the floor board? But, if allowed, this seemed like a much cleaner setup. URL to pic attached to show the channel size and depth and location. (I still don't understand how to do images) Thanks so much, we are getting very excited and making very good progress!
