I finally had some time to complete a couple G4003G upgrades, a new 6" forged Bison 6 jaw SetTru chuck w/D1-5 back plate and an Aloris QCTP with several tool holders and a #71 parting tool.
First up the Bison...the instructions talked incoherently about machining the back plate hub to chuck for fit. I don't know what they are smoking in Poland. In any case the G4003G spindle measured within .0001 on both the face and axle so it was good to go. I mounted the Bison D1-5 back plate and measured, again face and axle within .0001 to .00015. I have .003 slop between the Bison back plate and chuck for dialing in to zero with the four SetTru screws. Plenty of depth in the back plate so the chuck hub does not contact it so I'm not seeing where this back plate needs to be machined. Darkzero??? I managed to get the chuck dialed in to aprox .0004 with my brothers .0005 indicator after my CHINA .0001 indicator fell apart internally.
I now have a Mitutoyo .0001 indicator in my Enco cart. I turned some steel rod in a quick test, finish is I improved over the factory 3 jaw chuck, TBD if its the Bison chuck or the Aloris QCTP or a combination. I used the same tool and insert.
Here I have converted over to Aloris tool holders. The studs are rock solid tight in these tools holders and the set screws don't SNAP when loosening like the China tool holders. Man just the slightest pressure on the Aloris QCTP handle grabs the tool holder, and it has plenty of crank after that to further tighten. I love that the handle is now out of the way and both left and front tool positions tighten and loosen in unison vs the factory G4003G piston QCTP where one tightens while the other loosens and you have to reposition the handle, and the handle is in the way. When tight the Aloris handle is pointed at the operator. One can reposition the handle to point in any direction.
See that #71 parting tool, I'm going to give it a test on aluminum today. I tried it on that steel rod with the coated inserts, frankly it was no better than old parting tool that steel just seems to hate these coated inserts. I get FAR better finish with the sharp polished aluminum inserts while turning and they hold up well, but the sharp aluminum parting inserts I have quickly fail on this steel. That's how I ruined the Glanze parting tool. In any case I need to do some more testing with this #71 parting tool then report back.
Here you see me setting tool heights on all the new Aloris tool holders using a tool height idea I stole from someone on the forum.
