Hey everyone this is my first post here. Anyway I do all my own welding and fabrication and I want to build my own velke. I was planning on using a trailer gate hinge for the up and down hinge, but I cant seem to find a good product that would work for the left and right hinge. The best idea I can come up with is getting an old bike and cutting the downtube off of the frame were the fork goes through and using that piece. I was just wondering if anyone else has done this and what they used for that part. I saw the one Flex-Deck made and that is a real good idea using a ball hitch. I made some of the pieces and bought a trailer gate hinge so I would like to try and finish with the standard velke design, but If that doesnt work out I am going to start over again with Flex-Decks plan.
