Ever since I found out that the Sherline CNC Mill is actually a little CNC lathe that was converted to a mill, I’m supremely interested in getting this back into a lathe to compliment the Taig.
Thanks to @xquared, that machine has been brought to life recently as a PCB mill; but it seemingly has difficult (and expensive) problems that relate to mill operation that might not affect it being a lathe as much (ie x axis backlash)
I propose we do a group build of a CNC circuitboard mill.
Doing this would not only get us the circuitboard mill that people have wanted for a long time, but also, once done, freeing the Sherline to be converted back into a small CNC lathe.
There are a number of ~$300 CNC mill kits of this sort on Amazon.ca. Maybe that makes sense, but I suspect that between the membership, we will have a good number of extra parts kicking around to come up with most of what we need.
I, personally, have NEMA 17 stepper motors to offer to the cause.
Is anyone interested in helping build 1 CNC so we can end up with 2? Seems like a good deal to me. Our high profile group builds are great for our community, and given the size of the new mill is pretty small and the force load on it is also small, we could probably do this on the cheap.
Anyone have parts they’d donate to this cause?
