Re: How do i make this part??

Cory,

the reason why were making out own is because as richard pointed out, it will take a lot more load off of the wheel, and i don't want to cantilever the motor shaft too much by having a 3" long hub, mounted on the end of the shaft.

Rhichard,

I am going to be using a 20" x 1.5" wheel with 36 spokes. The design did go very well (I can't take any credit, it was first made by Trevor Blackwell). He had made three pairs on current projects that i checked out, those things are as solid as a rock, they take lateral load fairly well.

doug,

I actually used 20 skyway wheels on my first prototype of the scooter, but they started cracking due to (what i believe) was the lateral load on it.

Don & eveyone else

what i was told when trevor made his, is that he made a mandrel that bolted on to the four holes. So when he flipped it over he could chuck the mandrel on the lathe. Would this work better then doing it the other way??

I had some 3" diameter Aluminum stock that we got for this years robot (something like 6' of it, tooo bad it wasn't just a little bigger) I tried makeing a smaller version of something that looked just like it. It started turning out pretty nice, the part i was having trouble with was boring out the insides. It was probably because of the tooling that we have at the school...I'm thinking about buying a set of my own cutters. anyone have any good places online to order lathe cutters??

Also, facing off that angle in the cavity seems to be the one thing i'm not sure how to do, any advice?

thanks!!
