Here's an update on my mods. If anyone's interested
Looks like not much left of the original machine but the bench,base casting and mill table. What did you use to make all the parts? Looks like a great build if you could post some more details on all you have done. Got a kink in my neck trying to look at the one picture.
As you can see I used the lathe headstock spindle which has a MT4 taper you can find collets on ebay they take a 1/2-13 drawbar. I achieved more possibilities with this by mounting the lathe chuck. I have a HF spindle that I can mount on the table and use the main spindle as an A/4th axis.
As far as making putting this project together. I used a craftman drill press, a magnetic drill press and a surface grinder.
great job, so what is the other milling machine you used to build it, like instructor37 said not much of the original machine left. The only thing that looks similar to my 1991 shoptask is the green vice.
