Yes like those! I must have lost track of this thread but luckily it has moved to the the sites home screen for some reason.
In any event that drill press and vise has me wondering how do you avoid broken tools? I can understand taking very shallow reps of cuts for normal end mill work but you described a cut down end mill to cut the bottom of the T slots. That would mean cutting all the material at once. I can’t even imagine doing that manually.
On a full size mill you get feedback from the crank and sound from the mill to help you gage feed rate. With the tiny cutters you are using how is it even possible to “feel” is you are feeding correctly. Waiting for the tool to break and then backing off a bit won’t work. I’ve never used a Taig or Sherline mill so maybe there is enough sensitivity on these machines?
Sadly if I tried to build that vice and table like you did I suspect that I would have a bucket of broken cutters by now. You have produced some amazing work!
