Thanks Richard. I'm shopping for a tool post. I figured BXA was the size I needed. Nice to have a visual confirmation. I have a Standard-Modern Series 2000 11-20. I think it's the next generation newer, 11" version of your machine. Cheers!
Many years ago I bought a Dorian BXA for my Southbend 10L Heavy. It worked just fine. I bought the Dorian because I was familiar with them and liked the design. Their tool holders were also the first, as far as I could tell, to have a 3/4” height for the tool. They were using a higher quality alloy for the holders so were able to cut the bottom thinner. That made it easier to get to center height with a 5/8” tool. When I bought my current Southbend FOURTEEN, I moved it there. With that, I was able to use 3/4” tooling. A friend has a 15” LeBlond. He decided to get a CXA. I don’t see any real advantage for most people. The only one I know of is that he can buy the abundant used tooling in 1” size on eBay. The manufacturers are pretty accurate about the sizing for their tool posts. Aloris and Dorian give slightly different ranges, but it doesn’t matter. A definitely agree about buying a wedge post rather than a piston post. If you’re going to make heavy cuts, if your lathe allows it, or drill a big hole, the piston post can allow the holder to twist a bit, while the wedge holds it solidly along the entire length of the dovetails.
I have been a Machinist for 44+ years never knew or cared to know about the difference in the tool holders but often wondered what they were with the different letter designation now I know great video very informative on selecting the correct one for your application
I am a complete novice when it comes to lathes and milling machines, but I am a great lover of machine tools. I have very nice Atlas lathes, a 618 and a 12x36, both with rocker/lantern style tool holders. I want a QCTP, but I was unsure as to the considerations I should resolve. This presentation has significantly increased my knowledge of QCTP. Thank you sir.
Piece parting a lathe back together to be Atlas 12"x54" regular ole machine. Having the slide compound from a 10" lathe, the BXA is perfect. That extra inch makes it all work.
This was a very interesting video , I have never seen the comparison laid out as well as you did. I purchased an AXA wedge style last year and I am well pleased whit it for what I do. Thanks for taking the time to lay it out this well I am sure it will help many others that are in the market to buy one.
The correct size tool post is determined by and should be as close as possible to the compound width so you can utilize the full cutting capacity of your lathe.
Something not dwelt upon in detail was the ability to choose larger indexable insert tool holders with the larger throat size of the BXA size holders. The same issue of tool height and range of adjustment exist but with your Stand. Mod. compound rest height to center line, you've got the ability to use full 1/2" or even 5/8" HSP steel cutting tools or shank size indexable carbide insert holders for most procedures. This is valuable when using boring bars/holders for the rigidity offered by the extra diameter. I have personally found the only issue with the BXA came with trying to use insert style parting tool holders and trying to get the holders low enough to pick up center line of project. I have had to revert to using smaller parting tool holders if desiring to use my insert styles than I would have chosen otherwise just to get the tool down low enough. This is not a problem if using the dedicated parting tool holder that comes with the BXA kit other than you're now reduced back to using high speed steel parting tools.
Thank you so much for this video. It saved me so much time with research. I worked as a machinist years ago for a short time but all the tooling was already there so I never learned what any of it was called or what meant what. I just purchased a 10” Atlas Lathe and I know it will work for most things I want to do but probably only well enough that it will make me want a better one like yours.
At work I have put some 3/8"-1/2" "shims" under the tools where needed. We have a Parrot QC. If REALLY odd tool I've sometimes mounted it upside down and "reversed" the lathe, a Harrison Alpha 460. The lathe is quite ok, but the cam-part (AlphaCam) is crap! And almost no other cam speaks "Harrisonian" 🤨🤬.
I just bought a 13x40 turnmaster and the company that he bought it from threw in a Aloris CA-1 and I just found out that tool holder costs 2 grand new. It’s worth as much as or more that I paid for the lathe.
Great stroke of lucj for you, and kindness on the part of the seller. It seems to me that Aloris is the standard by wich all others are judged. Cheers.
I watched to learn and you seemed to address using high speed steel and not carbide holders which can have larger shanks to hold. I have seen a lot of video that it takes modification on a lot of the smaller lathes for mounting bolts size.
Yea, that's fairly common. A Grizzly G0602 (10x22") and the next size up should according to these charts be OK with a BXA, but with an AXA you don't have enough height to run a 1/2" tool without modifying something (I've been cutting the bottoms off my tool holders but that's a PITA since they're mostly hardened).
Where are you located, and where did you find a used Standard-Modern lathe:? That's an old one; I used to work for them as a draftsman. Those things will last forever if you service and maintain them.
It was a Kijiji deal 15 years back. It was originally used in a vocational school. It is a great lathe. I am on the east coast, in Nova Scotia. Cheerrs

I have a Grizzly G0709 13X40 & a Grizzly G4003 12X36. I use a BXA on both. they give me lots of flexibility and are very affordable.

How you show the adjustability with the ruler in the background is great! Are you able to show the same with the parting tool holder? Because the parting tool is held at a 4° angle, I'm trying to determine if the holder will drop low enough (and still be able to have a useable amount of tool sticking out) before I purchase a quick change tool post.
I have a 16mm parting tool. The part that holds the blade is located near the bottom on an angle like you mentioned. I still have 12 mm available to move it up. Cheers
I have a KC-1620CLM, that says the swing is 16". Height from top of compound to center of 2.3". I find it hard to believe that if I use the manufacturer's info, I need a CXA. Seems way too big for my little Chinese unit. Anyone else have one??
I bought a KC- 16x20 also , l would love to know what size quick release tool holder you bought ( if you did ) cause I'd like too purchase a quick release tool post for my lathe . What size do I need too buy, tks
@@Johnson0781 @David-qd3ff I have the same lathe but with a different name. I am looking at a BXA tool post for it. What size tool post did you guys go with?
@@MegaEverythingElse Haven't Bought any yet , useing it the way it came in Crate , Sure will down the line. U are saying BXA . isn't the a bit small , Ithink CXA should work Good , TKS for Replying.
@@Johnson0781 Yea, so this lathe has a very big swing over the bed for its size, just because of the milling function. everything else on the lathe is tiny compared to what a 16" swing lathe has. The compound on this lathe is pretty small and so is the cross slide. Normally 16" swing lathes are 4 feet + long with massive parts that can use the CXA post, which this lathe certainly cannot. This lathe is sized much closer to a 9" swing lathe. I am actually debating between an ANA or BXA for mine, still trying to figure out which is best. I may measure width of my current turret style post and compare it to the quick change types.
I should add that I do modify holders as necessary to take up to 3/4" tool and I have a couple parting blades that just barely get low enough to be on center ( I think I shaved the holder a bit on that one too).
Can I ask you about your 4 jaw chuck. I have one that I think is the same with the jaw scroll drive being a 1/4" hex allen key. I bought mine second hand hand and the allen bolts have been rounded to the point where i can't tighten the jaws down very well. Have you had the same experience? If so do you think there might be a solution rather than throwing it away?
Hi. Mine are not in the best shape either. I ended buying a new chuck key that had crisp corners and I use it with attention. I recently made one for the 3 jaw on the milling machine because of the same concern. Crisp corners may buy you another few years. Otherwise I do not know of a source for new . Mine are square as opposed to hex... Cheers.
No they WILL NOT FIT EACH OTHER. But if you have an AXA and wish to use some larger tooling, don't be afraid to open up an AXA tool holder to fit larger B sized tools. Just get out the carbide. The Chinese tool holders aren't that hard to cut to size. ;-)
Make sure the gibs on the cross slide and compound are tightened properly, and work on backlash. Minimize the length of the tool sticking out of the holder. Speed, feed, tool condition and proper relief. And experiment with the position of the tool post on the compound.
Hey. There is a large t slot in the top of the compound. The set came with an oversized t shaped metal block that you can mill to fit. It has been drilled and threaded to fit the rod that goes through the center of the tool post... Cheers.
Interesting. You said that one of the reasons was accuracy.....so how accurate is this tool post? I mean when you put a tool holder on the thing, lock it down and turn a diameter.....then take it off..then put it back on....is the tool back in the same place or is there a shift...how repeatable is this thing? While its nice to "quick change" a tool.....its even nicer if its where its supposed to be! I already have a piston type chinese tool post. Its not bad but not very accurate positionally when switching tools. I am planning to buy replacement posts and so I am genuinely interested in your opinion. Many thanks.
Hi Wayne, The wedge style is the only type I have owned and my choice was based on the expressed opinions of others. Here is a video where a guy does a comparison. czcams.com/video/Mt4qPD6YPuM/video.html I will make a point of doing my own comparison at some point. But for now it is much too cold in my shop... :) Cheers

Hi. From what I can see the 000 tool post holds the 001 tool holders.... example: Tool post:DMC 250-000-000 Tool holder: 250-001,250-002,250- 004, 250-005, 250-007, 250-010 Cheers
