Hi, all
I cut the crank out of an Murray Cruiser one-speed bike and cleaned it up and welded tabs to it so it can mount on the center boom of the AZ Warrior with pinch bolts, per the plans.
Here's some pictures of the crank being primed and the crank and bearings, races, etc., which cleaned up very nicely. Not too exciting but might interest someone ...
Since I've motorized my bikes, I no longer shift gears. I just put the derailleurs in a gear that is low enough for me to peddle from a dead stop to help save the clutch from wear. Other than that, I rarely peddle and I haven't shifted for 3 years. The derailleurs are pointless to me.
So, I'm planning to use the crank from the Murray and the rear wheel from it with the coaster brake and single rear sprocket to see if that works for starts. If so, I won't need any derailleurs at all.
I don't know if the coaster brake will be enough. If not, I'll put calipers on the front wheels.
I ordered two BMX 20" wheels with 48 spokes and 14mm axles for the front wheels and am waiting on those. Cost was $80 with shipping. I couldn't find affordable wheels that were strong enough that offered disk brakes.
The plans call for cutting up matching head tubes and making steering kingpins from them with extra hardware and fork stems and a very heavy mounting tab.
I just met a guy who is building 2 trikes based on the 'Fleet Trike" web site's plans and he used the 'bushings and bolts' approach to kingpins detailed therein. I looked at his finished product and was very impressed with the simplicity and feel of the steering.
So, I decided to make the "bushings and bolts" version of kingpins rather than cut up head tubes. I bought the bolts, bushings, washers, etc. but couldn't find the steel tube in the right sizes so I'm waiting on that. As soon as I get that, I'll build the kingpins and then go back to the AZ plans.
While I'm waiting, I started on the seat, which is made from plywood. The plans don't specify the thickness of the plywood so I'm guessing on that.
I'll post pictures and details on the kingpins as soon as I make them. That should be interesting...
