Got up monday and decided to built a power draw bar for my bridgeport clone to speed up tool changes. Finaly got around to anodizing and installing it today. Here are a few pics.
Looks like a nice job to me. You wouldnt by chance have a DWG and spec sheet for parts on it that you could pass on. I have thought about doing this before but have never gotten around to all the measurements. Any help would be great.
Now all ya need is a auto tool change system and you can sit back, drink coffee, and design stuff.
Red cylinder = motor to rotate collet spindle & air cylinder pulls it up to release tool in collet?
it sits above the draw bar normaly and the air cyl shoves the motor assembly down to engage the draw bar , air cyls are in the same air circut as the motor so it spins at the same time the cyl shoves it down on to the draw bar. I used the original valve off the back of the red impact wrench, push the button and it ejects the collet and tool out into my hand in about 2 seconds
Didn't realize that was an impact wrench.Originally Posted by panaceabeachbum
All I can say is, you must be Scottish!
