I picked up a Taig 2019 mini mill recently, and have been using it to do some CNC engravng while I learned how to use my software and get a feel for my machine. Mostly I used some 1/8" shaft stuff to do some engraving. Today I decided it was time to make some tight fitting solid t-bolt nuts and rails to fit in the table. Something a little better than the flat plates that came with the mill. Also helicoiled to a common size so I could pick up a variety of different length screws to use with clamping fixtures.
Thinking everything would be honky dory I sliced some 3/8" aluminum plate on the table saw to 5/8" wide strips So I could mill it down to 1/2" to fit the table grooves. Then I got it clamped up on the mill table with a couple welding clamps. I used the shaft of an 1/8 mill point to get the bar straight roughly to the table travel, and proceeded to swap collets to use a1/4" flat end mill to rough material off of one side only to find out that my 1/4" shaft mill point would not fit in the 1/4" collet with the collet snapped into the nut. Then I tried with the 3/8" collet with a 3/8" shaft end mill and got the same results. The ER16 is what is supposed to be used in this mill, and the collets where clearly labeled for the size I was trying to install and use.
Am I missing something? If I took the collet out of the mill head nut I could force the shaft in, but then it would not snap into the nut at all. I measuered the shafts of the various mill points I was trying with a caliper, and the 3/8 measures .375 and the 1/4 measures .250 so I know its not that, but hey I had to check and make sure right.
