    Finished, except I have no brakes. The cable in the kit is too short so I will pick one up today and it will be complete. I rode it around some last night - what fun!! My wife and I made the seat. It's big enough for two to ride. All scratch built from scrap in the shop. I had to buy the tube...

    tig & mig

    As a new welder, you will want to use C25 MIG gas (argon/CO2). That will cover everything you will need for a long time. Buy the largest bottle you can because the small ones cost almost the same as the largest, due to fees, etc. For example, 125 cf bottle is a good size for most hobbiest. Where...

    Update: I have my Predator 212 engine, and my Azusa 8" kit arrived last night. So far I think everything is coming together pretty well. Still a lot of work to do. I cut off the forks to right length and almost finished fabricating the front fork tabs. Still got to cut out the slots for my...

    OK, I have welded up the two sides of the frame. Inside dimension is 17.5". I am planning to put gussets in the back lower corners with a 5/8" hole for the axle. Just wondering, if the two frames are spread at an angle, does that create a problem with the axle holes? Will I have to round them...

    OK, you are helping me think this through. So if I want the frame a little larger, so my "knees are not in my ears", as long as I measure the engine, allow enough room for it and the gas tank, and give it a little to be sure there is clearance I should be OK. Maybe someone who has used the HF...

    Hi, Fabroman. Thank you for your reply. So if I buy the Predator engine, I still need to know how much clearance I need from the top of the engine to the top frame. Say the engine is 11" tall (I'm just guessing), should there be 2", 4" or more clearance so total inside the frame needs to be 13"...

    I want to build a simple mini bike like I had in 1960. I'm saying it's for the grandkids, but I just want to try to build it and expect I'll be the main one to ride it. I know I can buy a used one cheaper, or even buy the frame cheaper and easier than I can build it, but I'm a fair hand at...
