Boom and extras

We got the boom installed after several structural modifications. We also got the first version of the intermediate gear assembly mocked up. There is still some adjustment to do before the finall mounting. It still looks a little odd but it's getting close.

I'm reconsidering the three chain ring on the front. As it stands now I'm going to have 42 different speeds. Any more will have some duplicates and also be complicated.

I'm going tomorrow to get the materials from Grainger to build the axle to connect the two bike drivetrains. The axle is 3/4 linear bearing shaft combined with some flange bearing and pillow block. Hopefully this will tie together correctly.
