Heavy cuts and mini don't work well together. I made this little spring type tool holder based
on pictures of them on the net. One big difference in this one is that there is full capacity
of your cross slide when using this tool holder. It will mount right up flush with front of the QCTP.
It reduces or eliminates chatter when taking large cuts like is shown by the .250 groove shown in
the demo picture below. Form tools with a radius work equally as well. The pdf file shows the dimensions.
The 3/8 inch hole in the top is for a 3/8 inch roll pin. My pin was .385" in diameter so with the 3/8 hole
it is a tight fit. I pressed it in with the vise.
This tool will accept tool bits in 3 orientations. In addition it can be installed on the right side or left side of the tool post.
1/4 and 3/8 inch tool bits will fit in either the left or right side of the spring tool holder when the holder is mounted on the left or
right side of the tool post. The front holder will take short and wide form tools. 1/4 inch tool bits will fit in the slot that is adjacent
to the tool post but 3/8 bits will not fit there due to limited width of the slot.
