Thought I'd share what I've come up with. 2 twenties, 4 coors OG and some old snowboard binding parts and hardware and this is where I'm at. Only letting me upload 1 photo a post. I'll keep them coming.
The base is a 10" keel roller bracket I picked up from cabelas for $20. The wheels are harbor freight, $8 a wheel. The other stuff I had laying around. 2 bolts to hold the wheels on, 2, 6" long 2x4s, and leftover piece of ramp plastic.
All 3 keels on the ski make contact with the dolly.
