Axle Woes!

Axle broke again last week. The case hardened bolt I used was sheared off. Picked up another and only lasted one ride. Decided to go with something bigger but that was going to work since I had destroyed the coupler ( sawed off end of 3pc crank). Cut off the last remaining 3pc crank arm I had to set it back up but realized I still was having a problem keeping it together.
After several days of helping dad with the porch. Well we poured the sidewalk today then went to work on the bike this afternoon. We first were going to try and sleeve the coupler and try that. Dad to the rescue. Dad saw an old steering sector off an old truck under a bench. We tried to find the other piece to the steering coupler but no luck. Luckily for me we have a frame from an old International Traveler that still had the sector on with the complete coupler. I'm going to get a buddy of mine to Tig weld the steering coupler to the crank arm end. I've cleaned out the inside so that the nut can go in with a socket to secure it to the bottom bracket on that side. The other side I'm going to try and grind down the axle enough to fit it in the other half of the steering coupler. I'll have to cut the axle to fit but if this works it may take care of a lot of my problem in this area. I'll try to get some pictures up soon of this adaptation.
