Machinist School - New Mill Repair

New milling machines typically do not have 5/8 slots .... they are not straight and measure about .636, neither metric or American. The slots that do exist are cut short so that a shaft cannot extend past the table end.

Glen Hendricks came up with a solution:
1. mill straight slots to a common size
2. Cut bevels at the top of the slots to accept shafts

Above, you can see the 45 degree milling tool that Glen designed and built. (You can see the slots that he cut as well.)

Now a shaft can be clamped to the table without having the problem of the end of the table being in the way! Yay Glen!
