I'm looking to add a quick change tool post to my lathe.

I'm sick of playing around with shims trying to get the cutting tools at the correct hieght.  Quick change has a simple looking adjustment for that.

I'm looking through my Enco catalog at the phase II tool posts...I see two that look like they apply, but don't understand the difference...

505-2253 (100 series) says that it is for 9-12" swing lathes.
505-2172 (200 series) says that it is for 10-15" swing lathes.

I have no clue what is different about them, and which is more desireable.

Or am I on the wrong track?  Is there a better setup available?

Always appreciate your advise....


I'm becomming quite comfortable opperating my mill, buut there doesn't seem to be a lot of lathe talk around here.  Seems like the lathe is almost as useful as the mill...what gives?  - Josh M.

The difference is in size.  100 is smaller than 200.  I used a 200 on a 12X36 for quite a number of years and it was perfect.  I have since transferred it to a different lathe and it is a bit small.  To use smaller bits, I have to shim under the adjustment screw.  

Any problem you might have with the 200 would be just the opposite of that.  You may, I'm not sure about this, have difficulty getting 5/8 bits low enough to work at the centerline.  Using the 100 on your lathe might leave you with the same problem I have with the 200, not enough height adjustment to get a 3/16 bit on center.  

I think if I was you, I'd be getting the 200.  It is more massive, and that is a good thing.  mike

The lathe is actually more useful (just less used) than the mill.  You can actually do many milling operations in the lathe, but a mill is more convenient.

The QC toolposts come in at least 4 sizes, depending on the size of your machine.  The size will also dictate which size toolholders you need to buy to use with the post, and of course they get more expensive as they get larger.  If you're doing production work, get the largest size that will fit your lathe, you'll be able to get beefier tools to fit it.  If you're doing hobby work the smallest size that fits is usually most convenient and less expensive.  For your machine I'd get the 100 series.  This is size-equivalent to a Dorian AXA series.  I forget how Aloris numbers their tools, but it's the small one for them too, and you'll be compatible.  You will not be compatible with KDK - nothing is, except KDK.  

A friend of mine bought a phaseII for his Logan lathe, and it's been a nice toolpost.  The only issue he's had is that the knurling toolholder wouldn't adjust low enough.  This was rememdied by removing some material from the bottom of the toolholder.  (Not post!)

Good luck!

You could make you own "not so quick "tool holder
You just make a holder that fits you current holder ,in this holder you of course have to shim the first time you put a tool in it ,but after that you can take it out and put it back without readjustment ,of course you will have to tighten 4 screws every time instead of one on the quick ones ,hence the term "not so quick" but no need for hight adjustment wen put in

Hope this makes sense

I am using a 200 series on a 13" South Bend.  I might be inclined to use a 100 series on your 11" lathe.  The Phase II tool posts are good tools.

Hi, if you have  a look at the grizzly blurb for your lathe, it's model # G9972Z  11" x 26" Bench Lathe w/ Gearbox.

See the 11", it means that you can swing 11 inches diameter workpiece in the chuck, with that particular lathe. The 26 inch refers to the length of the bed, from chuck to tailstock.

The Enco catalogue with the Phase 11 quick-change toolpost - # 505-2253 (100 series) says that it is for 9-12" swing lathes.

So that would be the appropriate toolpost, for you to buy for your lathe.

Clemson and radish are correct, the 100 series in the PhaseII line (or the AXA size in the Aloris or Dorian lines) is what you need for your 11" lathe.

I put a 100 series PhaseII on my 10x24 Logan and it works perfectly. Before I bought it, I had borrowed a friends Series 200 tool post, to try out, and it was just WAY too big for the 10x24. Even the 100 series is a bit too big if you're using cutters with shanks larger than 3/8" square, but you can grind the cutters down to a smaller shank or open up the slot in one of the tool holders to make the bigger cutters work.

Tool holders for the AXA size Aloris and Dorian tool posts also fit just fine on the Series 100 PhaseII post.

I imagine what he was asking is, since 11" falls within both the 9-12" and the 10-15" ranges, how do you decide which to get. This is something I have wondered myself -- the answer is not obvious and could only be determined by actual experience.

My HF 12x36 lathe has a Grizzly 200 series set on it and it fits just right.  I tried it on a friend's 10x24 Logan for height and Doug is correct, it is too large and too high.  I would recommend the series 100 set for your lathe.  

The quick change tool post/holder was a major improvement over the 4-way tool holder that came with my lathe.  I like the tool holder that has a small v groove in the bottom of the cutter bit mounting channel that allows mounting round bits or a reamer shank in it.  It's the only type I get when I need more holders.

I have that lathe and have a 100 series QC toolpost for it and it's perfect. Best accessory for the Grizz you will buy. Get a couple of extra "regular" toolholders right at the start, if you don't you'll end up buying them a couple weeks later so save the wait and buy extra right away.
I keep a left turn, right turn, threader and a special crowning tool constantly installed and swap the crowner with whatever I need, the others stay.

I put a 200 series on my 12 by 36 inch lathe and its a good fit-- and stout...Then I put another 200 series on my ancient 20 inch lathe, had to make a longer centerbolt and sit the post on top a 1.250 thick steel washer to get it high enough ...But, but, but, is handy to have same toolholder on both them lathes as I can swap toolholders between the two machines.......
.
And I have the smaller 100 series on my South Bend Heavy 10 inch lathe..Thats a good fit but I am tempted to put a 200 series on it - would need to mill a half inch off the bottom of it but then all the lathes would use the same toolholder.... a hundred times I have grabbed wrong size toolholder from the community tool shelf..
