Phase II and BXA
I couldn't find the thread where we discussed Phase II and BXA but I decided today to dump
my Aloris AXA wedge and go with Phase II BXA wedge for my Clausing 6903. Now, assuming the post is worth having, I can build up a collection of holders which is what QC is all about. I'll also get to use some BXA holders that came with the lathe. The only regret is my Aloris AXA threading holder won't fit. Not a big issue since when one threads, the compound tends to get set to 29.5 or 30. Changing out a tool post isn't a big deal. Careful work with a carbide dovetail cutter could convert the tool holder to the new post. I might try reworking my CDCO holders if it works out okay. Change that, the CDCO holders will be the guinea pig, if it works out, then I'll attack my Aloris threading tool holder. My metal working content for today. Wes |

Now, assuming the post is worth having, I can build up a collection of holders which is what QC is all about. You can, and should. I'll also get to use some BXA holders that came with the lathe. I presume that you got the set, so you have five holders (of which one is probably going to sit there unused -- the knurling one. I used a scissors style knurler until I lucked into a genuine Aloris BXA knurling holder which has the two rolls on arms mounted on dovetails with a leadscrew driven by a knurled knob which is left-hand thread on one end and right-hand thread on the other, so turning it in one direction moves the arms together, and the other direction moves them apart -- while maintaining the height adjustment for all sizes of workpiece. The one thing you probably should do is to get a box of good American made metric set screws (8mm IIRC) to replace those which hold the tools. The ones in the holders are likely to split when you torque down on a tool, making it very difficult to remove the tool in the future. (Of course, they may have improved the metallurgy since I got my set.) I actually took the time to re-tap the holes to an inch thread which is quite close to the metric thread -- and which means that I can use the same Allen key in both the Phase-II and the Aloris holders. But that gun tap which I used is probably not good for anything more now. That is some tough metal in those holders. :-) The only regret is my Aloris AXA threading holder won't fit. Not a big issue since when one threads, the compound tends to get set to 29.5 or 30. Changing out a tool post isn't a big deal. O.K. I normally leave the compound at 29.5 degrees -- and only shift it if doing left-hand threads. Except that I had to shift it the other night, with the lathe covered with newspaper, prior to using a toolpost grinder (the first time I have actually *used* one which I have had for a couple of years now. But there was a task which really required that, so it was time. :-) Careful work with a carbide dovetail cutter could convert the tool holder to the new post. Even the Phase-II holders are tough. I hope your mill is rigid enough to handle the carbide in that job. But I think that you would be losing significant rigidity in the old holders. Maybe just look for another threading holder in the right size on eBay -- and maybe the threading bit will move between the sizes. But for threading, I tend to use laydown carbide inserts in one of the BXA holders which extends out closer to the workpiece for better rigidity. I did some 3/8-32 threading in D2 steel the other day, and it worked nicely. That D2 steel is *expensive* compared to A1 or the various water and oil quenching steels. $47.?? for a 36" rod of 3/8" diameter. I might try reworking my CDCO holders if it works out okay. Change that, the CDCO holders will be the guinea pig, if it works out, then I'll attack my Aloris threading tool holder. :-) My metal working content for today. A good start.

Phase II and BXA
I have an AXA on my Sheldon L-44. Chrome ways (na-na! :-) )
I have made several work holders for it from iron. I suspect a nice block of leaded steel would be a delight to machine. Why not make a holder for the threading tool or holder to hold the AxA tools themselves. Like the threading tool, a boring bar might be smaller and needed - and so forth. Martin Martin H.

Phase II and BXA
You will be very happy with the choice. I have a boatload of quick
change holders and it works out really great. Just yesterday I needed a pipe bored out, was done in 10 minutes. |

Phase II and BXA
I've had only 1 problem withp Phase 2 tool posts. The mounting screw had to be cleaned and
re-loctited to hold it in place. This happened with 2 sets of Phase 2. It also happened with a home-made quick change mount from a friend. Bob Swinney "Wes" wrote in message ...
