UPDATED VERSION 2:
I finally worked out how to get the original cross-slide gear free, and it turns out I was slightly out on the pitch of the gearing with the original models. I've updated the files and everything is much smoother now.
I've added a little tolerance in the gear models, but they may well be a bit tight and you'll probably have to run a drill through them to get a good fit on the shafts.
You might notice that I'm using a metal gear for the transfer in the screenshot - this is a 34T DP20 Myford change gear with a brass bushing pressed in and it's working really well.
-----------------
Well, here it is. I finally got around to messing about trying to create a power crossfeed mechanism for my lathe. For context, my lathe had the crossfeed nut on the leadscrew and the geared cross-slide shaft but none of the gearing in the apron.
STANDARD DISCLAIMER: This is a good chunk of trial and error in Fusion which arrived at something that worked for me. I haven't given it a whole lot of use as yet, will be interesting to see how the printed gears hold up. Your mileage may vary etc.
Printing Instructions:
Transfer Gear and Gear Selector: Fine without supports.
Drive Gears: Printed just fine with PrusaSlicer organic supports turned on.
I've put a standard M8 thread in the selector lever so it should be easy to attach your favourite kind of knob.
