I've seen many different home built trailers for bikes, but I wanted to go at least 90% or so Aluminum so it would be lite weight, here are some pics of what I got done this afternoon, as you can see it wont be anything real fancy but it will serve me well for what I need a trailer to do. I used pop rivets and ALUMIWELD for all the joints so far, the round tubing that the wheel will be mounted on is 3/4" Conduit, didnt have any Aluminum tubing but had a 10' joint of this in the shop. I'm using a 16 x 1.75 bike wheel & tire, I wiil be putting a 3/16" thin lite plywood floor in it and I may build my sides out of it too, unsure about that right now will depend on how the bike pulls it before I add the sides. But anyway here are the pics of what I have at this point so far. Three Cheers for ALUMIWELD....! I really like this stuff...!
