The tri car and I have returned. On the feel good days as rare as they have been I did get a little done.
I rounded out the bottom bracket a little so I could press in two sealed bearings with a 1" inside dia. and a 2" outside dia. Into the center of the bearings I pushed a 1" piece of tubing with a 1/8" wall to act as a jack shaft. I'll weld a pair of sprockets together and then to the 1" tubing. I have some welded up but they are the wrong tooth count and need to be replaced.
A slit collar will be fitted onto the opposite side of the drive sprockets to hold the jack shaft in place in the bottom bracket.
Inside the 1" tubing jack shaft there are two 3/4" outside dia. and 5/8" inside dia. flanged bronze bearings. These fit in each end of the 1" tubing and a solid 5/8" round bar is inside the bronze bearings.
This solid bar will be the crankshaft for the pedals. How to mount the chain ring is up in the air at the moment but I'll work on that when the time comes.
Tomorrow I'm going to get the front brake cables and take the motor up to a machine shop who seems willing to do the key way.
I bought a used exhaust pipe from a small engine repair shop for $10 that I removed a 90 degree elbow from so I can run the exhaust down to the muffler. Hoping that by the first week of March it will be on the road.
I would like to thank Goldie for explaining what he did on the Flying Merkle. I have adapted it to my build as best I can.
Please click on the photo and it will take you to Photobucket. I have typed explanations on the photo's.
