Are you using 25 or 35 chain?

Also, what is the material for the gearbox sideplates?
254 typically uses Delrin, as it is much lighter than aluminum and strong enough for this application

Finally, when looking at your picture, there are grooves cut out in the front of the side tubing.
Am i correct in thinking that you will be putting another black crossbar in the front?

The sprockets are for #25 chain. The reason that they are so large is because I was originally planning on using cross braces that are as tall as the sides and the sprockets would need the chain to clear them. I simply haven't been motivated to change them.

The side plates are currently aluminum but theres no reason they need to stay that way. The grooves in the front to so that the sides are identical and can be switched without needing to have one of each. The actual would probably use another to mount bumpers.

As a compromise, you could always make the front and back crossbraces the full height of the sidebeams, and use the half size ones for the in-between crossbraces.

This would allow you to keep the sprockets small and to still retain more strength than having all half size crossbeams.

I also like your gearbox design....

Yeah, definitely inspired by the same team(s) yours was.

Actually, my design was inspired by a whiteboard sketch by James Fry. Who knows where he got his ideas, might have been there. As for the actual mechanics, mine was a single speed, akin to this one, rather than a two speed, akin to the ones you posted. Same shape though (a no-nonsense, no real extra material design that I wholeheartedly approve of).

Pretty hard to say this design posted was a alteration of your design alone though. West coast is obviously known for their drive designs and I must say that the link you posted was up way after a few greats such as 254 and team 60. Just throwing it out there.

On another note, alex, thanks for sharing your take on the west coast drive with the rest of chiefdelphi it's always nice to see what all the teams get out of other great role model teams.

Thanks

How about using CD-Media?
http://www.chiefdelphi.com/media/photos/25814
http://www.chiefdelphi.com/media/photos/23573 (And scroll down on this one)
http://www.chiefdelphi.com/media/photos/25071

There's a few more there too. You may have to search for both the teams involved.

righto, uploading now.

The gallery includes photos from regionals and off season events that either 254 or 968 attended, as well as build photos and other misc stuff.

Most of the pics are a little better than the stuff on CD Media.

thats where i found it, unfortunately they don't have any 2008 robot pinups yet. (cmon guys!) but there are some great pictures from previous years!
