I started fitting the bearing into the outer leg.
What I had to do was cut a new size sideplate that Dave E. uses in his build.
The plate had to be mount 3/8 further into the leg opening to make up the
difference that the bearing used.
The bearing has more than enough turning radius and has very little play.
I used Dave's blueprint to center the bearing and you can see the drilled
holes that Dave marks on the blueprints.
I have 2 drive system in mind and hopefully one of them will work.
I guess I should warn everyone not to try this until I get it all worked out.
