Got tired of the OEM tailstock being so heavy and awkward. So I cut it up. I can lift this one with one hand. Put it in from the front. Gained 4 inches of Z travel. With the QCTP, I can get what the turret can’t in certain situations. Strip some paint, deburr, check for flatness (it has been rough machined). Top plate shimmed to height. Two eccentric bolts adjust centerline. Less moving parts than the original. Just finished it so still learning. G30 will be the parking code as my CAM uses tracking point of last tool used. Could get exciting if I screw up. You will need a mill, and some sort of tailstock quill or other doner. I put a 0.750” x 8” ground, center drilled rod in and top was w/in 2 tenths, front 2-3 tenths. Haven’t moved it and checked for repeatability yet but it should require minimal tweaking. Any one interested in the CAD let me know.
That’s pretty cool. It works with the turret tools?
Yes, it’s definitely close quarters. G30 will be in the middle somewhere. I can move the QCTP down about 1.5” and gain a more diam and still hit center, which won’t happen. #2 Neutral tool and QCTP will get anything at te far end. I will definitely be moving in slow motion until I get comfortable with it. Total length is about 7.25” in second to last position, minus drive dog. Could get creative there too depending on diam. If you’ll notice, I flipped the quill upside down for clearance.
Bill Storbeck, Beck Machining, gave me the idea. So thanks Bill! He does gun barrel chambering work. Mounted the quill to the X cross slide. He has no turret, just a QCTP, that I can see.
Go Army!
Nah, go Navy…….
I’m interested in the cad files
Thanks, Jerry
Ok Jerry, how do you want them? STP file? Actual files are .prt. I can set up a folder in Dropbox and send you a link. Just need an email address. Do you have an OEM tailstock or are you sourcing a quill assy? Let me know.
