Just some progress on the low boy.
Used my miter saw for all the angled cuts [22 1/2°] but when I got to this point used the drum sander on the Shopsmith to sand where the front assembly and back meet up so everything comes out just right.
Marked for center to be sure and not miss and then free hand drilled for dowels for a little extra support.
O!!! I should mention I’m making mine an 8 wheel trailer and all so shortening it from a 17” deck to a 14”er so my excavator will fit just right and so will my Dull Dozer if need be..
-- There's a hundred ways to do anything, alot depends on the tools at hand.
