A friend is wanting me to assemble her a trike powered by a HT motor. I have located a replacement sprocket that attaches to the rear axle with 2 set screws,will this work ? EVEN if I have to weld it to the axle after it is lined up?

I don't recomend welding it. If ya gotta change a bearing or something you're gonna be in trouble. If you can drill and tap it out to take a heavier set screw it should work just fine. I found this out through trial and error when building mine. The little set screws that come with it are almost useless. If it has only one set screw then drill and tap another set screw into it On the other side of the coller. I don't know if the pic will do you any good but check out the rear end pic of the trike in my album. I can't take another pic, sold it.

Trike

Will I need to file flats on the axle for the set screws or will that weaken it?
The axles I've seen have a slot for the set screw, I guess yours dont. Filing a flat (Not too much) should be OK. It's a steel bar thats either 5/8" or 15mm as I recall. A little to make a flat surface for the set screw is not going to weaken it enough to worry about. Even if you do it to both sides. (to ad that extra set screw)

Another question

Useing this attached and driven by the HT motor on a single shaft axle would not the peddles be turning also? If so what can I do to prevent it?
 
Trike

This is how I did it. I used a hub that has a freewheel on one side and transfers to a solid sprocket on the other side for the peddle chain, I then used adapters that "set screw" to the axle and attached all my solid drive sprockets to the axle. The pic doesn't show the hub very well at all, But you can get the idea anyway. An example of the type of hub I used is at e-bay item # 230486506486. Then just run the motor chain straight to the axle. So, in order from left to right, It's the motor chain(solid mount,)peddle chain(another solid mount) then the disc brake setup. Hope the pic helps some.
