I fixed a disc front wheel and caliper onto an old YZ drum fork front end.
I loaded Aluminium wire into the mig and tacked a bracket into place with the caliper squeezing the disc and my fabricated bracket bolted to the caliper. Next I removed the fork and disassembled the tube to access the lower which I filled with water to help with the distortion while I ran full welds.
This worked a treat, I was very proud that my limited engineering and welding knowledge at age 14 had achieved such great results. I rode that bike for years without incident.
Would I recommend doing this again - Nooooo Way!!!!!!
A bolt fell out of the front caliper of my KTM whilst trail riding, locked on the front brake, and damn near killed me!
I thought back to my modified disc set up and counted my blessings that lady luck was on my side for those years, things could have gone soooo Wrong!!
Read danger danger!!!
