So, here is my finished diy Gorton pantograph to knee mill build. I found a good deal on a 1hp totally enclosed Dayton motor which really beats the washing machine motor I had been using. Looks better too. Note the 5 1/4" by 4" milling vise. It seems to fit pretty good and has a nice and tight action. The final spindle speeds range from a low of about 245 rpm on up which matches anything my ER-20 collect can hold cutting steel. I sold the extra parts off the panto which paid for the motor and milling vise. Next is shimming and tramming the mill and playtime.
h The last photo shows two old forged wrenches I had; I milled the lower one in my new mill with a 3/8" dia. carbide end mill to open it up to hold the collet shaft steady while the collet nut is loosened. It cut through that tough old steel like a breeze. It's my first actual job on any mill making something useful (other than the machine keyways mentioned previously in this thread. So far I am having lots of fun for little expense.
