What would be a fair price? Do you have a source to get these parts? I thought we could get them from AZ, but that doesn't seem to be the case. And we haven't had much luck finding any machine shop to do small jobs. The guy I found just asked me how many I wanted of each, the FDAX34 and the DBAX34, for the Aurora. So I figured I would put it out here in the forum, see who has info.

these could be used


they could be used with a screw on rotor adapter for the disc brake as well

The plans include a how to build your own adapter sections. That is how it was done in 2008 when I joined. The Adapters Brad made were nice and made building eaiser. However they should not be an issue to make units form old bike hubs as shown in the plans. Thus for one off machining it cost a fortune to make them.

For the Hub flanges I used 2.5 inch fender washers to get them to be round and printed the hole position and used contact cement to the hold to the washer while I drilled all 72 holes with a hand drill and the washers held to a board with screws as shown in the tutorials.

When I made my disc brake adapter I welded a fender washer to a shaft collar and then drilled the mounting holes for the brake.

So if there is a will there is a way to make the adapters your looking for without going to the greeat expense of having them machined. When I a quote to have Emachine shop make them it was like $200 for the first one for seting up and then the rest were way less expensive.

I used the adapter Emma linked to but had to drill it out for the 3/4" axle I used to build with. At the time I was building I was pushing 285. Thus I wanted the heavier axles at the time.

Hope to see your project posted here. We love Photos.

here is how I made my own for a fraction of ready made. Only revision is use a 15t sprocket instead of the 3/4" collar. Welding the sprocket was easier to get straight.
I purchased the hubs from http://bbbp.net/
