Unless I can substitute other WCP extra-long shafts and cut them to length, I will have to wait on AndyMark to restock.

By the way, I also discovered this morning that Rhino3D for Mac has a 90-day trial license, and works great to open the STEP files AndyMark provides. After the trial expires, the installation notes tell me it will stop saving but will still open and view files. Might be all I ever need on my Mac!

Are you looking at the WCD version of the WCP gearboxes? The WCD version uses the same shaft as the standard version, however the WCD bearing block, and space for sprockets take up alot more room. When using the standard version, the shaft is probably close to 6 inches long from outside the gearbox.
