It does have cuts on the outside on the left and right, version II will have them front to back too.I use 1/4 amsteel ropes instead of the strap on my primal steps just splice loop one side drops weight a lot and I seem to get it tighter easier than with the straps. I like your base I'd need some grip cuts on outside edges or might be slippy on the boots when damp. I have some 3/8 plate think that's thick enough for platform?
Ha ha, at this point pretty low, it’s too time consuming to be cost efficient. but I’ll try post a drawing if anyone needs a bit of help.What's the odds of you shipping a platform to me?
