A year ago I decided to add a motorized crossfeed to my Chinese 10x22 lathe.
It has taken me quite a while to get to a point where it is actually functional, but here it is.
In hindsight I should probably have bought the lathe with crossfeed included, but I did't realize that I might want that at some point.
Thankfully this gave me the opportunity i design my own.
I thought it would be better to add such a crossfeed with a separate motor, instead of having to engage the annoying change gears.
It would make a lot less noise, and I would be able to control the feed independent of everything else.
this is what I came up with:
all done, build and working.
Still bits and pieces missing, as the gear/motor has no cover, and I haven't made the dial graduations yet.
This is basically a small stepper motor driving a toothbelt/pulley system, that can engaged/disengage with the crossfeed spindle.
It is activated by pulling on the handwheel center knob, and disengaged by pushing it back.
Of cause there is a little more to it as the motor need a bit of electronics to make it all go.
But everything is made by readily available materials from Ebay.
I'll be happy to share all details, diagrams and parts if anyone is interested.
For now I have included my latest sketchup model, but everything is available if anyone wants.
Feel free to use it, or abuse it.
The included skecthup model isn't an exact model of the actual product, I ended up adding 2 more bearings, but it is very close.
I'll probably post a picture of the real thing taken apart anyway.
Edit: I spend some time updating the sketchup model today. It should now reflect the actual build in more detail. (crossslide_public2.zip)
