I have my ATC working great. Now it's time to make a dust shoe so I don't have to chase the spindle with a hose .
I have seen the style where you can set the height of the shoe to a fixed level and the spindle travels up and down, like the one in this video (starting at 0:30): https://www.youtube.com/watch?v=lx-7lTJryJY
But I also have a tool changer so I would need to have it move up and out of the way. I had planed to use pneumatic cylinders to lift the shoe, and make the mount for the cylinders adjustable. But my problem is that since the shoe will be at different heights, how do I account for the fact that it will need to lift different amounts before it hits the mounting?
Most of the time i am using bits that stick out about 1 1/4" but I do use bits up to 2" long,
I have attached a picture to show my set up. The point where the round part of the spindle meets the housing is the bottom of the mount.
