Here’s a car rack that’s easy on the eyes and the budget. All you need is 48 x pre-finished shelf and two 48 x dowels. Cut the dowels in lengths and paint them to match the shelf. Use a spade but to drill holes for the dowels.
Homemade PVC kayak rack , can store 4 kayaks,paddles ,kayak car rack .made from 1.5" schedule 40 PVC 40"wide X 5' long (cost around $250 in 2015 prices) has 4 swiveling casters with two being lock kind ( otherwise rack will roll away when loading) . To make the wheel mounts I used 1 1/4" metal conduit cut to 2.5' long and weld a pre-drilled plate for the wheel . I bolted thru the PVC and conduit pipe to lock them together. The conduit helps reinforces the PVC when pushing the cart around .
