Ya, forgot to mention insert for the wheel itself. I would suggest staying away from key ways, they sheer occasionally.

I've been using key ways for 2 years now and my team have been using them for 4 years (since the team was founded) and we never had any problem with them, so i don't using them. But it is his choice to make since it is his bot. there are much more methods then hex or key... Those are just the two that andymark sells...

our team has always used keys, we never shear them, but we loose them, all the time. however we dont want to buy a hex broaching kit. if possible use a hex broach, but keys work just as well. something i would look at is staying away from gearboxes all together, jester-drive uses only belts to gain gear reduction. picture here. http://www.chiefdelphi.com/media/img...09401a44_l.jpg

When we stalled a motor, (electrical hooked them up backwards) we sheared a key, We also have had issues with losing keys, they are tiny little things....


What other methods are there? Friction mounts really aren't viable due to costs/vs reliability, and they are really more used to couple shafts.


Also we never have had to broach anything while using hex shafts, we just use the bearings and andymark mounts. Because they are circular anyone with a mill can easily mount them to a bot.
