70 O'lander Frame measurement and Ripple Question

[fullahotair]

All,

Question 1: I am doing a body off resto on my 1970 Overlander. I am welding up some new parts and pieces and noticed a peculiar dimension I am hoping someone might be able to provide some insight. The outrigger dimensions are all a consistent 14.75" from the frame rail. The top channel that is over the step is 15.25" from the frame rail. I have pictures that show the plywood floor extending to the edges of the outriggers and the edge of that channel. I just don't seem to recall a 0.5" bump out in the plywood for the step...

I have the plywood still, so i'll likely just put that back on the floor to see what it looks like... The only thing I can think of is maybe the plywood floor extended past the edge of the outriggers a small amount and i didn't notice it...

Question #2: Anyone else notice these ripples in the frame near the axles? They are consistent on both sides. If the trailer took a huge hit, i would expect them to be behind the axles and not uniform on each side.

Any thoughts would be appreciated.

In case anyone wants to see all the pics...they can be seen here:

I'll go about this question another way. The following are my measurements front to back. Edge to edge of the outriggers from side to side. (See attached pic).

83 3/8" (these are the shorter triangular riggers)
91"
91 1/2" (step)
91 1/2" (step)
90 7/8"
91 7/16" (accounts for extra plate around axles)
91 3/8" (accounts for extra plate around axles)
91 3/8" (accounts for extra plate around axles)
90 15/16
90 15/16"

Curious why you wouldn't have them all be consistent front to back...exception being where the radius for the corners start.

Opinions welcome.

I haven't done a frame off on anything as 'new' as your trailer but based on the few I've seen, nothing was precise. It seems the frame shop measured with a micrometer, marked with chalk and cut with a torch. I'd probably make them all 91.

Thanks for the reply. I have also noticed the lack of "precision" through out the deconstruction of the trailer. I think would have to work to put it back together so haphazardly.

I am going to measure the old plywood tonight to see if that dimension was consistent or not.
