Thanks for the comments!
Marine grade 3/4 plywood is 52# per 4x8 sheet, and I would need 4 sheets with some cut off, this is around 208#. 2x6 lumber is 2# per foot, and I have 426# of lumber, so yeah the lumber is twice heavier. I like the idea using the 2x6 lumber, so I can just replace a board if it gets damaged.
I have 1,247# total weight just the trailer. Add in another 1,000# for (2) sleds and I am at 2,247#.
I think I will use (1) 3500# torsion axle, or I could use (2) 2200# axles, that should handle the weight.
It looks like the torsion axles come in different "start angles" 22 degrees, 30 degrees, 45 degrees and 0 degrees? Any ideas on these start angles? Is the start angle how high the trailer will be with no load? Just wondering and concerned if I use a 22 degree start angle, and the wheel hits the trailer when I load the sleds?
