Looking to build a rolling cradle for my Top Gun. Wanted to get the boat off the trailer and in the shop, Has anybody built one of these or have any measurements, dimentions or pictures? Thanks Farmer..

Harbor freight is having a sale on their heavy duty wheel dollies. This is a cheaper way to get you your casters.

Yardarm.com pretty reasonable .

Pot o Gold- that's funny you mention that. I just picked up 4 of the moving dolly's and made a boat dolly for my sweet 16. Then my friend came over and surprised me with a real set of boat dollies...But my set worked just as good!...and they only cost around 100 bucks for both.. 4 dollies, and a couple 2x10's...Did the job!
