So with the steering planned out, the frame needs to come next.
Really have not planned the frame at all...
I really want to nail that "worked hard and left in the paddock for years" look, so I started looking at what the rustiest steel and donor frames I had were and found my answer:
Most of you may not know what that is, but a few of the older members might, that is the bones of my first attempt at a super heavyweight cruiser bike, super wide bottom bracket, single sided hubs, motorcycle tires, tank for an airhorn...
It started out as a proof of concept for using 3 piece bottom brackets for single sided hubs, but, once I proved that would work:
I kind of lost interest.
Then RRB#08 came along and I had a plan to do the heavy weight cruiser idea bigger and better, and so BigJim was born:
After BigJim was done, and worked so successfully, it seemed silly to go back to the old build which had some mistakes and design flaws.
It wasn't a total waste though, as you may be able to tell there were a lot of parts recycled into later builds, plus the single sided hub idea (which was the original intent of the build) has been used a number of times since. (Including the rear wheels on this trike!)
Time to allow some of that frame to live on!
Unfortunately some of that hard won patina on the steel will be lost through cutting and changing, but I am sure it will rust up nice pretty quickly after it is done.
On to the bench for surgery:
Angle grinder makes rapid work of thin wall box section:
Started mocking up ideas of how to reassemble the parts when I finally did this:
There is potential, I will need to spread those forks (?) a little to match the diff supports, and chop out that super wide bottom bracket, but the basic design is there...
Do it!!!
