I bought a Shars wedge type about 6 months ago and really like it. I've owned my Atlas/Craftsman 12/24 more then 20+ years and much prefer the QCTP over the old lantern type. I find the Shars to be much easier and faster getting the tool height correct, and it will be even better when I can afford a couple more tool holders.

[@mackdog3270]

Yep, I bought a mini lathe last year and I've spent all kinds of money on the thing. Far and away the most expensive extra I've purchased was the tooling and quick change post. It was about half the cost of the lathe itself, though of excellent quality. The only thing more expensive than a lathe are the tools needed to use the thing.

[@mrpete222]

Well said!

[@stxrynn]

[@kevinmartin7760]

I have an AXA-size toolpost on my Myford ML7 (7 by 20) and I usually use it without the topslide so I can more easily get the tools low enough, especially the ones with larger shanks. The one I have is made by Dorian Tool and it has yet a different locking mechanism, where the central part of one side of the dovetail pushes outwards to lock the holder in place. I guess this product was designed to work around the Aloris patents while still using as many as the unprotected good ideas as possible.

[@mattholden5]

Good synopsis. Thanks, Mr Pete. One mod I made to my AXA size lathe was a heavier ball on the end of the handle. I wanted to replicate the almost effortless locking of my Dorian CXA. With more mass on the AXA lever, a gentle flick of the finger locks the tool at its natural torque - no risk of pulling the tool post out of alignment, even if only modestly tightened to the compound. I've rarely heard this kind of thing mentioned on any channel, but on a all precision machines, the torque you apply to the fasteners is expressed as microscopic deformation to precision surfaces somewhere. This effect is amplified on smaller machines, since there is less to thread into everywhere. Maybe some part of my follow-on rambling could be Size Matters mini episodes 4-6?

I liked this video Mr.Pete. You mentioned that the older toolposts had a tapered locking arm and that it looked more elegant. Well, I'm going try to duplicate one of those if I can find some dimensions. If not I'll just wing it. Even though I don't have the taper attachment on my old SB-9, I guess it's been a while since I've disrupted my tailstock :)

[@mrpete222]

[@daveticehurst4191]

The wedge type is much more rigid as it pulls the holder back against 2 surfaces of the dovetail. The piston type only pushes it against 1 part of the dovetail hence not so rigid. Thanks for showing. Regards from Australia.

[@grntitan1]

Agreed. I have both type. I much prefer the wedge. I noticed on the piston type that it would slightly move the tool holder off square. May not matter for many operations, but when you need your cutting tool to be square to the workpiece, it matters a lot.

[@M4nusky]

I've just upgraded from piston type to wedge this winter and it's a world of difference. The piston one was a bit faster (ie loose) but didn't repeat very much and you could feel it working under heavy loads unless I put shims between the faces. So far the wedge type is so much more rigid and repeatable.

[@aceroadholder2185]

I was given a mainland Chinese BXA piston QCTH and it works fine in the home shop. There is one caution about Chinese tool holders themselves. They basically work well but the tool clamping screws are awful. Your hex key Allen wrench will crack the screws in no time. My True Value hardware actually had this style screw in stock and they were Italian made. I've never damaged one with a hex key. Always keep the lantern style tool holder on the shelf. Just the thing to get into a tight spot when the body of the QCTH would be in the way. The 4 way tool post that comes with most Asian bench lathes is even more likely to interfere with getting the cutting tool where you need it. Cheers from NC/USA

[@mrpete222]

[@mark111943]

Thanks MrPete enjoyed that but I was hoping you would describe how to best determine the size based on various measurements (spindle height above the compound slide maybe?) rather than predominantly relying on finding your lathe model in the catalog.

Great video again, I may have watched all of them. I love my Aloris AXA wedge type. I'm working on a tool to set the cutter height referencing from the flat surface on top of the cube. It is 'L' shaped in elevation view and has a slight curve in plan view to accommodate the circular part of the locking mechanism. So far so good. Good enough that I use the prototype and seem to be in no hurry to build version 2.0.

I'm with you on the wedge action. I like the feel you get from that. I don't have a piston type. I have a few of the four way turret lathe style, too. I like those when I am working on multiple parts. Storage has become an issue. I started a project in December, but I haven't finished it yet. Hopefully, it'll work like I plan!! I still use lanterns on the Logan, but there is a plan for some Harold Hall type quick change in the near future. Thanks for the lesson!

I have a very cheap bench top lathe with a tool post that has a fixed hight for the cutter. Your video showed me a tool post where I can adjust the point the cutter makes contact on the stock. Thanks. Showed me I need a better lathe and tool post. On my cheapo lathe I always get a nib on the end of my stock. Drives me nuts plus shows me I'm not cutting properly. Can't complain too much for the price of $245 I paid for it though. It was a clearance item at Tractor Supply. It at least got me started on lathe concepts.

Good one Mr.Pete. I'll be watching for the upcoming videos. The tool holder that holds a hss cutter vertically would make a great short subject. I would be interested in knowing a little about the cutter relief angles that are built into it plus your general thoughts.

[@paulhunt598]

Aloris was the standard when I entered the trade in 1982. I bought a brand X import piston A size for my Craftsman/Atlas. It is a huge improvement over the lantern post for tool changes. It is a far cry from an Aloris. Adam Booth uses a very different style of quick change tool holder that has indexing features that Aloris doesn't offer. He has talked about his "after market" source for his style. I have never seen his style in person. I assume that the Aloris is far more standard and probably less costly. Thank you for plugging SHARS as a legitimate import option for us hobby folk that shy away from Aloris cost. I usually hold out for premium brands on the used market, but tool holders and tool posts are hard to find used at any price. I bought my brand X tool post from Lost Creek Machine back when Dad still ran the business. They used to annually set up a large tent in the flea market at Midwest Old Threshers, Mount Pleasant, IA. The reunion folk really put a squeeze on the flea market crowd. Many vendors quit coming to the reunion and I quit going, partly for that reason.

[@mrpete222]

I have seen that one that Adam uses. But that is the only one I’ve ever seen like that. I wonder what happened at the threshermans Fair regarding the flea market?

I also purchased the Shars, wedge type. I've had all sorts of trouble with mine. I've used Aloris in the past and there is a world of difference between the two. My budget was tight and the price of a used Aloris is crazy. Now I'm not complaining I knew what I was buying.

[@mrpete222]

Noted!

[@DonkeyHotie]

Adding to what you said about piston vs wedge style: repeatability is the desirable advantage to the wedge style. Piston style holders use the angled dovetail faces as the datums. Any difference in handle pressure will affect how much the holder springs open and where the tool tip ends up each time. The wedge style holder locks the holder up against the body of the tool post in both the front and back, establishing Z. The front dovetail indexes in-and-out (X). The measured result on my CXA Dorian is literal repeatability in tenths. This translates into being able to change a turning tool to a parting tool, cut off a part and return to the turning tool, in exactly the same position. As people move to DROs or CNC, the repeatability becomes even more important.

[@oldwaddie3259]

Great timing! I've been digging through older vid's looking for one from a couple of years ago where you had told us which size you use on your Clausing. As a gunsmith apprentice in the 1970's I used a 12 inch Clausing with KDK tool holders. I later bought the machines from my mentor when he closed the shop and have used the KDK's ever since. The KDK's are not as stable as the Aloris I don't believe and I've decided to switch over. I've watched your channel for some time and enjoy it very much. I'd thought you had cut back on the number of videos being published as they stopped showing up on the recommended list of the channels to which I'm subscribed. Glad to see that was not the case. Sorry to be long winded here. Thank you for all the work you do. You make 1st class videos.

[@mrpete222]

Thank you very much

[@howardosborne8647]

You're spot on about the wedge type being better than the piston type. The wedge type locks the holder far more positively and is much better at giving repeatable accuracy on removal and replacing the tool holder in relation to the workpiece.

[@mrpete222]

[@charliechmelar9788]

I really quite like my dovetail-type QCTP, but have been thinking about how I can use tool offsets in my DRO, and find myself feeling awfully envious of the swiss multifix type 40-position toolposts. Sizing those however seems like even deeper wizardry than this!

[@johanneslaxell6641]

We have a Parat QCTP on our Harrison Alpha lathe, it is "adjustable" in 15° increments if I remember correctly. There are pros and cons: yes one can change tools but is limited to that 15° steps. On a NC-machine it is in my opinion a smaller problem than if manual machine where the compound is necessary...

[@paulkinzer7661]

I got the piston type kit from Shars right after I got my 10-inch Logan lathe a couple of years ago. I kept the lantern tool holders that came with the 1954 lathe, but I'll admit I have not used them since getting the quick release system. As someone who is no expert, and completely self-taught in the past two or three years, I'm really happy with this Shars kit. I could see getting the wedge type at some point because what you say about them makes sense. But unless I come onto one that is used, or find a pile of cash, it probably won't happen. I'm looking forward to these upcoming videos! I have found ways to make the five holders I have work for me, but am curious to see if I should add to them.

[@mrpete222]

Your big machines make my machines look kind of puny

[@herbholmberg4474]

I added a QCTP some years ago to my 12" Craftsman lathe. I was and continue to be severely limited on tooling funds so reluctantly had to settle for a piston type model though i would have much preferred a wedge model. Of course price dictated a Phase II brand import with 5 tool holders. Though a bit oversized for the 12" Craftsman I bought a BXA. I have found no issues with the BXA in use and purposely chose the BXA for one reason. You can fit a scissors type knurling attachment to a BXA tool holder. You have to make your own if you have an AXA post, or at least you did when i bought my post. I think using a conventional knurling tool on an Atlas/Craftsman lathe puts a lot of strain and wear on the brass cross screw nut these lathes are equipped with that a scissors type knurling attachment does not. I considered buying an AXA post and a handheld scissors type knurler but did not want to go that route. Had my lathe been a heavier built brand i would not have felt i needed a sissors type knurling tool, but given the limitations of the lighter weight Atlas i thought my decision prudent. I have never been given reason to regret choosing the BXA post and have had no performance issues either in size, or due to it being the cheaper piston type post. That said, I would agree that an AXA post would look more appropriate on the machine and if not for the knurling issue I described would have been the post i would have chosen.

[@mrpete222]

I’m glad you had good luck with the BXA. It looks a little bit out of proportion, but it has been perfect for your purposes. I use a BXA on my clausing

[@herbholmberg4474]

@mrpete222 It does appear odd to the eye but has worked fine for my purposes and was chosen for the reason explained.

[@herbholmberg4474]

I have found since making this reply months ago, another option I was not aware of when I chose the BXA relates to tool holders. There are tool holders one can find that have an oversized slot that as I recall would accept a scissor type knurlung tool. If I had known about that when I was selecting my tool post I definitely would have opted for an AXA sized post. Also I seem to recall reading that the greatest disparity between wedge and piston type tool posts is repeatability in use. Being honest, I don't know how this disparity would reveal itself in use. My assumption is that disparity would appear if the tool holder was removed from its position on the post, then later reinstalled. But as I said, that is speculation on my part.
