& hub was faced off to .278 length thru bore to fit our space requirements on the shaft.

PS How is this useful to you?

Well, I knew the gear comes from sdp-si already but I find the other information extremely useful. Thanks so much. Do you think something like a 8mm bore with 2mm keyway and .24 length through bore would hold out? The actual keyway (length and width) would only be slightly smaller than what you are using. I would be gearing the Drill down to match the Chia.

Also, thanks for the offer of AutoCAD drawings but that I don't really need them. However, I would like to see a picture of how the Fisher price transfers through the plastic gears to the metal ones. Did you say there were 3 plastic gears for the FP geartrain? I couldn't see detail on that in any of the previosly posted pics. Thanks a bunch. It is a truly wonderful design.
