Installing a Quick Change Tool Post on the Mini Lathe - Scraping Included!
HTML-код
- Опубликовано: 28 июн 2024
- The Mini Lathes usually come with a standard 4 position toolpost and so did mine. If you have to often change turning tools it can be really tidious to exactly shim the tools to center height and the whole process takes way to much time.
A quick change toolpost was on my wishlist for quite sometime. But given the price of these things, I just couldn't convince myself buying one. I wanted to go for the Multifix style toolpost as they are here the most common ones and for me the ones I trust the most.
I also wanted to go for a high quality industrial grade product (that's really important when having the smallest and flimsiest lathe on the planet ;) ) and landed by the AXA company in Germany. They were really kind and gave me a whole set of their size Aa quick change toolpost for my lathe. They still produce them here in Germany.
For mounting I had to make a new bolt from higher grade steel and I had to mill down the top of the compound slide a little bit to get some room for the tools to adjust in heigth. As the milled surface didn't look that great, I scraped the surface with a quick pattern to make it a bit more pleasant to the eye.
All in all I'm really happy with this new addition as it saves a lot of time and makes working much more efficient.

Nicely done!
I go back and forth on wanting a Multi-Fix style tool post like this one. I researched all kinds of tool posts, and eventually went with an Aloris-style wedge-type tool post, thinking that it would be much easier to make custom tool holders. But I can't deny that the versatility of the Multi-Fix is super appealing to me, in spite of the more "complicated" tool holders (and I have yet to make any custom tool holders for the wedge-type). The ability to rotate the tool post to multiple angles, and return to a reliable zero is really awesome.
Thanks for your comment. The wedged type toolholders have the advantage that you can make the toolholders much easier by yourself. But I don't wanted to spent a lot of time making toolholders with my tiny machines and the multifix type ones really are super versatile and practical to use.
Man, you went from 0-100 _REAL_ quick with this one. Just skipped all the steps in between and went straight for the good stuff.
Yes, a bit overshooting perhaps :)
I didn't even know that such small multifix toolposts were available. From a quality manufacturer like AXA I suspect they are the better part of the cost of a new mini-lathe.
This size is the smallest available. It's called Aa and has 50mm length of the toolholders. And yes, they are a bit pricy but really well made and a joy to use.
Very nicely done; AXA did you a real favour there.
Yes, they did! I'm really happy with it :)
How can I contact AXA to investigate this tool post?
Love your channel. Thanks for showing how you change the gears on your lathe to cut threads. I have a small lathe and could not figure out how to read the change gear settings until now.
Cheers from South Africa.
Thanks for your comment! I really do appreciate that.
Congratulations, and beautiful work!
Thank you very much!
Great work.I like your way of action.Thank you.
Thanks!
Thanks for sharing 👍
Thanks for sharing!
As always: nice work! Great upgrade to your lathe, but that's also because you took a lot of effort to make it work well. Nice work on scraping the compound, I didn't see that one coming. Looking forward to your next video!
Thank you very much for your kind comment!
👍👍👍👍
Very nice work indeed.
Thank you!
Pretty sweet improvement.
Thank you very much! :)
I bought the wedge type with 4 tool holders as a bargain package from Banggood for my lathe and then bought 4 more tool holders on EBAY......the problem was they are not compatible as far as fit is concerned..........2 of the 4 were OK but the other 2 were too loose to tighten up but as they were so cheap on EBAY I decided to experiment by packing the dovetail faces with 1mm strips to see how much rework was required.
I took the path of Tig welding 1mm packer strips along the edges of the faces of the dovetails on the holders and then polishing them up......this worked perfectly and for any future purchases this is the path I would have to take if they didn't tighten up.
With hindsight I think I would have gone for the T37 type sold in India on EBAY which are as cost effective as the wedge type.
Thanks for your comment! I do not like these type of quick change too, holders that much but that's just personal preference :)
@@WeCanDoThatBetter Well they do do the job.........I'm designing a solid type tool post that secures the tool holder in a block without any overhang........how many more designs do we need?......LOL.
I came across the Dickson type QCTP in 1962 when I did my apprenticeship and was so wowed by the quick change aspect that I made one to a simpler design later for my micro lathe
👍👍👍
Love your channel and everything you've done with your lathe so far. I'd love to see a video on your tooling choices. What you use and why you chose it. I'm also curious what your training and background are. Very impressive skills I must say :) You've inspired me to want to duplicate what you've done with a mini-lathe of my own.
👍👍👍👍
Tolle Arbeit!
Vielen Dank! Freut mich :)
Great demonstration of a improvement mod to the mini lathe. Well-positioned camera views and great resolution footage. I feel compelled to mention something you have likely already factored into the job, ie. that flipping the bolt end-for-end in the 3 jaw chuck will cause loss of part concentricity.
It is great to see your work being done and it has inspired me to do similar on my lathe.
Thank you.
PS. I like the cariage dial. Will jump over to that video now.
PPS. The chapter marks in RUclips are great, thanks.
Thank you very much for your kind comment and feedback! Happy to hear, it inspires you to do similar mods on your lathe too. Thans for the hint with the bolt. Indeed, the part concentricity is bad, when flipping the part and turning from two sides. An axle or gearshaft I wouldn't machine this way. In this case, as it is a stationary bolt, it is not that critical.
Nice upgrade.
Yes, makes working with the machine so much faster and more convenient. thanks :)
OMFG I HAD NO IDEA THEY MADE THEM SO SMALL!!!! I NEED ONE RIGHT F'N NOW!!! I cannot find this product on their website, can you provide a link to the product page please?
This is the set I have: www.stahlhalter24.de/multifix-stahlhalter/sets-angebote/axa-schnellwechsel-stahlhalter-set-k00-multifix-aa-aus-1-stahlhalterkopf-3-drehstahlhalter-1-bohrstahlhalter_1203_1189
Really interesting to see this, I had no idea multifix posts were available that small. Was a bit confused at first while searching, because I thought AXA was the same as Aloris AXA but realised it's not 😁
Thank you for your comment! The size Aa I have is the smallest one with 50mm length of the toolholders. It's really tiny, yes :) For this machine its ideal. I had to look up Aloris AXA. That's interesting as it is a different style of quick change tool post and seems to randomly has the same name :) The AXA company I got my toolholder from is actually a german cnc machine building company which also produces the multifix like toolholders.
On my wish list
I recommend it :) A joy to use.
Nice video!
The things I learned starting scraping is that the standard sandvik scraper is much to stiff. Mill some slots in the middle will make it ‘weaker’, makes bending it a bit more easy. Which helps with applying pressure.
And the radius of the standard blade is quite large. R40 or R60 is a nice radius to start with.
Imo
Looking forward to the next video
Thank you very much for your feedback and tips on the scraper. Indeed the scraper I have is really stiff. Do you mean milling slots lengthswise? Or how did you do it?
👍👍👍
Nice work
Thank you!
👍👍👍
That is a nice upgrade, I have swiss made Aa on my Schaublin 102 and while original it feels a little small on that machine, for this one it looks right.
Thanks for your comment! Yes, for my machine size Aa is perfect. Schaublin 102 sounds really good ! :)
@@WeCanDoThatBetter the question is how are you going to add collets to the mini-lathe? For me that is the work holding solution that defines machines like the 102. I use B32 collets on my 135 as well but less frequently. What is the spindle bore on your lathe, too small for w20 I am sure. ER32 is probably the most practical option as you already have the collets although W15 or something like that with a drawbar would be more accurate and better for tiny parts
Oh my gosh...something not made in China! Looks very nice, I may look about for them...I USE AXA (sized) tool holders, haven't heard of AXA the company.
Superbly machined! Wish I had one set for my minilathe :-)
Thanks! Yes, I'm super glad to have this set now. It makes working so much more time efficient as tool change is much quicker now.
@@WeCanDoThatBetter It looks very solid and is really a piece of art. I have a cheap Chinese copy in aluminium, but it has rigidity problems (to add to the existing in the compound).
@@JoseSilveira-newhandleforYT Uh that doesn't sound good. Aluminium is not the best material for a tool post.
@@WeCanDoThatBetter Yep. It was cheap and I was tempted 🙂
Very nice work. What tolerances do you normally work with when using your QCTP?
This is awesome but oh my god can you tweak the volume for those loud operations 😱😱😱
Thanks and sorry! I keep that in mind ;)
No turning with the new tool post…sad/whining face 😩 guess I’ll just have to wait and see how you like it. Keep the video coming 👍🏻
Oh sorry, I missed that in this video. So far I used it the toolpost works great.
👍👍👍
I want one! But I can’t find it on their site.
I'ld be happy too if I got a free tool post, LOL.
Who is not? ;)
👍👍👍
Seems AXA tool posts are really hard to find. I followed your link and the website doesn't show them, or maybe I just missed it. Great video!
Thanks for your comment! I think AXA doesn't sell the toolposts directly over their website. You have to search for venders via google I guess. Good luck :)
I would not have bothered with the paper shim on a freshly scraped surface
Yes, the paper is probably not necessary but I thought I try it.
@@WeCanDoThatBetter You can also pin it to the topslide, that's what the holes in the bottom of the toolpost's central block are.
Hello! can you update the lathe to have transverse advance? and another to be a box with metric threads without having to change the pinions every time?
ruclips.net/video/XVkX3Zm9A4w/видео.html this is what I was referring to for the fillets.
I'm thinking about adding a kind of gearbox, perhaps a norton gearbox to the lathe to make threading easier. But that's for the far future. I first have plenty of other things to do. You mean an automatic cross slide feed? Would be great but there is really not that much space. I have no idea where to fit it.
I studied better the advance with the norton box but I think it would be better to have a decoder and a stepper motor to cut metric threads, the advantage would be silence and much cleaner.
👍👍👍
But how would Axa feel if Multifix started making Axa style tool post... :D :D :D
That's a weird branding thing. As far as I know is the name Multifix the brand name of the Hahn&Kolb tool suppliers quick change tool posts and there is a copy right on this name. So if you name the similar product from another company "Multifix" you might get in trouble with copy right issues. But I guess, that's just hypothetical ;)
👍👍👍
Funny comment, but the original Multifix as a company doesn't exist for some decades. AFAIK AXA has a license to produce these and name them Multifix. PeWe Tools have a couple of nice videos on the history of the Multifix, look this up if you're interested in it.
Touching the chuck with tool holder is much faster alignment.
Thanks for your comment! Yes, that method is quick and probably accurate enough. As I did this video together with AXA I wanted to show the most accurate way of aligning the toolholder :)
I would be interested to know what lathe this is.
It is from Artec, Germany. CJ-9518 / C2 is the name.
👍👍👍
@@WeCanDoThatBetter Can you recommend a source for 14mm round 42CrMo4/42CrMoS4 that supplies small quantities to individuals? Would you mind selling me some of your leftovers (ca. 100mm length is enough)? Or is bolt strength class 8.8 (turn down standard M14/16-8.8-bolt) enough?
Could you not just turn down the radius on the flange nut a little bit for clearance?
I didn't find the tool post on their website.
Hi, you have to google axa multifix or axa toolpost and I think you find a supplier. Axa didn't sell this directly as far as I know.
@@WeCanDoThatBetter They they are in stock but when time comes to ship, sorry.
Sofort etwas Gescheites genommen. Finde ich gut!
Damit dürfte sich der Wert der Maschine gleich fast verdoppelt haben! :-D
Haha, ja das stimmt in der Tat :D Wenn schon, denn schon :)
Wie sind denn so im Vergleich dazu die PWT PEWeTools Multifixe? Sind die auch gescheit?
@@marcoam2610 Da gibt es unterschiedliche Meinungen. Ich habe nur eines für das Abstechmesser. Die Anlagefläche für das Messer war konvex und musste nachgearbeitet werden da sonst das Messer schräg stand.
Für fast gleich viel Geld gibt es z.B. schon einfache Wechselhalter von Multifix bei SHV24.
@@d1rty1oser Hallo, da jeder Halter mit einer Masterklinge bzw. Abstechschwert geprüft wird, könnte das Problem eigentlich nur an ihrer Klinge gelegen haben. Mittlerweile sind weltweit einige Tausend unserer Abstechhalter im Einsatz und bis zum heutigen Tag gab es keine einzige Reklamation. Um der Sache auf den Grund zu gehen und um eine eventuelle Problematik in der Produktion auszuschließen, können Sie mir da weitere Infos geben? Welchen Halter haben Sie und was für eine Klinge wird verwendet?
W H, wenn Sie sich nicht melden, dann kann ich auch nicht helfen.
I would very much like to buy the same model QCTP you have for the same model lathe I have. I went to your link of AXA to try and purchase a set of this QCTP kit to no avail. I couldn't seem to find the model. Can you point me in the right direction? Also, I'm in the USA.
Hi, and thanks for your comment. Here you can buy them: www.stahlhalter24.de/multifix-stahlhalter/sets-angebote/axa-schnellwechsel-stahlhalter-set-k00-multifix-aa-aus-1-stahlhalterkopf-3-drehstahlhalter-1-bohrstahlhalter_1203_1189
I hope, they ship to the US. You can select this option on the flag in the right upper corner, so it shold be possible. Just contact them in the shop link above if you have questions.
If they don't ship to the US, Hoffmann tool distributor sells the AXA stuff too and definitely in the US too: www.hoffmann-group.com/US/en/hus/Clamping-technology/Lathe-chucks/Quick-change-lathe-tool-post/p/318000
👍👍👍
⭐🙂👍!
Ich wusste gar nicht das AXA immer alles verschenkt. Muss da auch mal anrufen....
Musst schon was leisten für, Meister ;)
Hey! You didn't show it in use! Let's see it make some chips, and some quick tools changes!
:)
Oh yes, I totally missed that :D Have to show it in the next video.
Great work as always, you should check out Clough42’s channel he just got the same tool post just a few sizes bigger 👊🏼👍🏼
Thank you very much for your kind comment! Yes, I've seen his video on the tool post recently. He has chosen the Pewetools kit and is a few sizes bigger, yes :)
So its a multifix copy.
Yes, it it. Multifix is the brand name from Hahn&Kolb tool supplier for this type of toolholder.
Isn't AA toolpost too small even for mini lathe?
Hi, Aa is the perfect size for this machine. It fits very well. On video everything seems to be bigger, but the machine is pretty small :)
Could have just bought a quality lathe in the first place!
That's one way to go, yes...
If the two posts you have is working that well why are you changing it I wonder I wish mine work that good which is the reason I'm watching this video see if I can get mine to work good on my mini lathe
You mean the old tool post? It works ok but changing tools is really time consuming. The quick change tool post makes working a lot easier.
I really don't understand taking the effort to scrape the surface without bothering to control it for planarity or even parallelism with the slideways. To then put a paper washer on it, well - it's just a total waste of time, isn't it?
As I wrote the scraping was just for better optical appearance. I didn't like the matt milled surface of the compound slide and as I have no surface grinder I took this as a scraping exercise. The surface for the toolpost hasn't to be super precisely aligned with anything. As long as the tip of the tool is on center height, everything will be fine. And the paper thing. I showed and wrote it in the video! Putting a paper between the toolpost and the compound slide is a recommendation from the manufacturer to gain better friction between the parts. Definitely an old school trick but I wanted to try it.
@@WeCanDoThatBetter I understand where you're coming from, but actually, in certain ways, you're wrong. the surface of the top slide should be perfectly parallel to the sliding ways of the compound. A non-parallel situation could lead to tool height problems if you rotate the toolpost.
In of itself, that is pretty much irrelevant, any difference is going to be of the order of microns on a lathe with tolerances (at least)10 times that. However, the top surface of the compound is the first reference surface of a cross slide, it's where you start from when you're rescraping a slide, and you've just milled it away. Which is fair enough, you have a reason to do so, but ideally you should be bringing it back to parallelism with the slideways.
I've never heard of the paper shim trick, though. Does it work?
@@WeCanDoThatBetter My replies here sound pretty negative, obviously, and everyone's an expert these days, feel free to take what you want from them. They're not actually meant to be all that negative, my bad as they do look that way. You certainly got a nice cosmetic finish with the scraping, so if that's all you were aiming for...
It's kinda like putting a carbon fiber look stickers/decals on things. It's not really carbon fiber, but from a distance can pass like it does :)
@@WeCanDoThatBetter The vids I've seen on YT re: scraping all instruct a side to side rolling (rocking?) motion as the carbide is advanced. The result is a curved/scalloped divit in the metal.
I haven't scraped a machine surface in, but after watching the 1st vid, I discovered a carbide 'scraper' I bought 45+ yrs ago at a garage sale, (then used as a gasket scraper for 20 yrs working as a mechanic), turned out to be THE cast iron scraper everyone says is the best to buy.
Got a new carbide insert for it, then messed around on a chuck of scrap cast.
I see what they're talking about w/ the side to side motion to get the scallops.
It's easy to do, but difficult to do it to a consistent depth & shape. I rocked on my fist, once I figured out the best way to grip it.
Having my entire fist contacting the surface facilitated the rocking & provided resistance, giving better control over forward advancement.
Check out some YT vids & give it a try. If nothing else, it'll give you even a better looking surface. The scallops have that 'real' look.

As I recall a couple of the better vids on scraping were done by @oxtoolco & @robrenz

What do you mean?
👍👍👍👍
Well when you get a nice tool post for free it makes the rest of use jealous.😡
Oh, sorry ;)
why is your lathe so loud....something doesn't sound right
That is because of the gears for the power feed are engaged. They are pretty noisy, yes. If they aren't engaged the lathe runs much quieter.
You definitely need to get away from the carbide and get some HSS tooling. The sounds your lathe is making with that tooling are horrendous.
To which part of the video you are reffering to? I guess the sound comes from the change gears which are rattling like crazy. I would never change my vhm tooling for hss these days. The tools I use for turning the 42crmo4 steel work just perfect. Look at the ships and the surface finish. I think it couldn't be any better...
👍👍👍
Ugh yet another youtube channel sucking up to sponsors. Paid content is ruining youtube.
I wanted a quick change toolpost and as money is rare I asked for support and got the toolpost for free. The tradeoff is to show the installation on my channel. To be transparent, I marked the video as advertising because I got something for free. Ok it would be nice if I had no need for any support at all and could be absolutely independent but as I'm not a millionaire I'm happy that there is a company willing to support me.
👍👍👍
