Right-Angle Attachment Question

appliedproto · Sep 7, 2006

I was wondering if anyone out there knows what extended drawbar is need for a ProtoTRAK K3 head...the Bridgeport, Index or Alliance type?

Also, is there a special screw and washer that's suppose to tighten the R8 collet/arbor in the attachment? Or do you have to make something work?

The Bridgeport screw was just a standard 7/16NF SHCS. Dunno about the washer.

I have a 3" long shop made extension permenantly mounted to the top of the standard drawbar on my supermax. has worked fine for 15+ years.

I use the regular draw bar with a thin wall socket, extension and ratchet.
