I am in a welding class at my highschool and we have to do a final project of our choice. I would really like to make a unicycle frame for my project. Are there any known tutorials or guides to frame building online anywhere. I would like the frame to be relatively simple (if possible) and it will only be the frame/seatpost holder/bearing holders. I wont need to make a seat post or hub or cranks or anything.
If there is a known source to help me out please leave it below, or if your extremely bored and wish to make one it would be most appreciate, but not expected.
I forgot…If you do not have any resources to help me in the building process, do you have any idea the raw cost of just the metal materials needed. Not labor or machining or anything, just raw materials.
I didn’t do the building. The lead thumbnail image found in the main gallery that leads to the teachndad gallery shows three different and crude drawings for the crown, but I can’t find the image. Maybe you can, if you want to search through the entire gallery.
Be prepared for possible movement from the high temperatures from welding.
the thread below, discusses three different types of crown designs. The first link in the thread is old and goes to Harper’s NAUC pix., but the crowns are described and then there are some other links in the responses
Steve Howard’s gallery also has some welded frames with step by step photos through the build process. The one I’m thinking of used stainless, purely because he had some.
From a web scan a while back getting steel tubing, in small lengths (1’), seems pretty easy in the US. Not too expensive. In the UK they are normally available by the ~5metre, which makes it pricey if you need a small bit.
You could just shoot George an e-mail, or make a copy of his frame. For a really simple frame; one of George’s first frames he built for himself was just a short peice of square tubing for the crown and round tubing for the legs and seat tube. Plus, you could just buy some stamped bearing caps from unicycle.com to use for the bearing holders.
if I remember correctly, they;re cheaper without the bolts. so you could buy one with and one without, or just two without and find some 1/4-20’s or something laying around. or sometimes Unicycle.com messes up and ships you the bolts even though you didnt order them.
