Possible to extend output shaft on WCP Gearbox?

[J_B_Wood]

Hello,

I am designing a West Coast Drive in which of course the wheels, but also all pulleys are mounted on the outside frame of the robot. This means I need a good bit of shaft space on my gearboxes to mount everything. (Subtract an inch as the shaft passes through a clearance hole in the frame. However, I've ran into a problem and am not sure where to go. On the output shaft of my WCP SS Gearbox (http://www.vexrobotics.com/vexpro/mo...es/wcp-ss.html) I have mounted 2 15mm pulleys, and need to fit a wheel on the end, but the axle is not long enough. Is it possible to order an extra long output shaft/swap it out for a custom-cut piece of hex shaft from our stock, or should I ditch the gearbox I'm using all together and find something with a longer shaft?

On the page I linked, it says the "extra long shaft" can be cut to length, but it seems that is still too short. Any ideas?
