Below is the list of parts and costs associated with the trailer upgrade.
Hobie 20 Trailer Redesign: Pink lines represent the two new Aluminum Crossbars |
The original Calkins Trailer had 2x3 inch steel rectangular cross bars with welded steel tabs. The tabs had holes to accept 2" U-Bolts. They are 8 ft long.
Original Trailer front cross bar. Welded tabs which accept 2 inch U-Bolts. |
The new 50mm M8 "Square" U-bolts are Stainless and ordered from Amazon. As with most things Amazon, they originate from China, but are decent quality and include the M8 Hex nuts and a straight piece.
Procedure:
(1) I ordered the 2 eight foot crossbars and 24" of aluminum angle online.
(2) I fabricated the brackets to connect the crossbars from 2x2x 0.125 inch 6061 T6 Aluminum Angle.
(3) The Angle was cut to length on my Mitre Saw running a Carbide Tipped 10" Blade from Hitachi. I drilled the holes for M6 Socket Head Cap Screws to attach to the cross bars and M8 U-bolts to attach to the trailer 2x3 inch frame.
(4) I have yet to assemble everything due to the weather this weekend. More to follow and photos during assembly.
