Help anyone know a way to fuse aluminum and steel

can also be done using couple hundred pounds of high explosive under quite a few tons of sand

normaly used to make things like armor plate tho....
 
If your not a world class welder don't try it. It can be done tho. For on road use only there is nothing wrong with a GOOD alumium frame. My Point Beach I built three years ago is still going strong. Ride it every single day. My DX-Al Mongoose with a rear mount 4 Stroke Is going strong also. I ride on smooth roads, check my bikes every day!

you motor and a HT style frame shaker are 2 WAY different motors
also rear mounting a motor takes the vibrations that the motor gives and moves them AWAY from the main tubes of the frame
 
I build Mb's. I'm saying the frame will hold up if it's a frame mounted 2 stroke, or a rear mounted 4 stroke. Aluminum is stronger in some ways than steel. Steel is stronger than Alumium in some ways. I was giving an example. Your milage may be diffrent :)
 
Saddle tramp

seen to many pics of alloy frames on here that have broken in less than 3 months of being used with a china HT motor
aluminum work hardens then cracks and your frame breaks from the vibrations

if allow was stronger you could use alloy forks with a hub motor... without a trip to the er and false teeth after you try it

HT motor... like a 20 pound concrete vibrator
 
question of fatigue life

The problem with aluminum is that you can only stress it a certain number of times before it fails. Steel on the other hand under certain conditions as a unlimited fatigue life. If you take a steel tube and stress it a certain amount it it will always come back to the original shape. Aluminum does not share this quality. I was looking at a website called Wheels through Time and on that site was a 1912 Indian. Somehow a steel framed motorcycle seems to have lasted 100 years without failing. This looks like a pretty good testimonial for steel.
