About the JB Weld:
It's great for small stuff, and in this application it should work out really great. But IT IS NOT a substitute for welding.
I had a friend of mine cracked his skull and knocked out two teeth when he tried to JB weld the frame of his bike back to the fork retainer. He thought that JB was a substitute for welding. I've seen stupidity and his name is James. James was in the hospital for almost three weeks. Nasty concussion.
JB weld doesn't actually weld things, it's just an extremely strong glue.
About your problem:
If one of your friends has a welder, see if he can do it. Most friends are willing to help see something cool become a reality.
Be sure it's squared up to reduce any wobbling. Vibrations at high speed can tear even the most well designed stuff into pieces.
Check and see how other people have solved the problem you are having, pull from those ideas. There are alot of people on here who have built rigs out of old chainsaws. I'm sure you can find some ideas from their projects.
The whole DIY thing is supposed to be challenging. But have fun with it too.
