Well first i never build anything on aluminum and second i appreciate your concern as far as being a novice when it comes to welding but what alot of people on different forums ive been reading say tig is the way to go for a bike frame welding. Although im a novice to welding i have my dad for one he knows how to use all the welding equipment and for 2 you can learn pretty much just about anything nowadays with youtube and thirdly im a very quick learner plus i had a different ideal for my bike build.
So with my new ideal what im thinking is extending the bike by 6 inches to allow room for the 125cc engine
So i plan on cutting top and bottom tube 3 inchs forward of the seat tube.
Take a 10 inch long steel tubing with the O/D just small enough to fit 2 inches on each side of where it slip fits inside the frame.
Next i will drill 2 small holes 1 inch in from slip fit on top going down and side going throug the frame through the slip fit tubing and once again through the frame on other side i will do this to all 4 connections. The point of this is to use the tig welder to put a tack on the inside part of the extension slip fit tubing.
Next once i have one side done with the extension slip fit tubing i will also use a tubing thats the same diameter as the frame to cover the extension which would be cut at 5 7/8 inch so when i slide the 2 peices of the bike frame back together it would leave 1/8 inch exposed for to weld all 3 together.
Once the frame is done i will take a 1/2 thick steel plate that would have a c < cut out on both sides so it will wrap the frame tubing which would then get welded to the frame as well
I was also considering welding a steel tube under the motor plate from the seat tube to the bottom tube
So with something like this i think i would want the precision that a tig welder gives you over a mig from what ive been reading.
Or can this project be done with a mig i plan on taking extra care and want it to look as professional as possible.
