Lathe Compound Mods for Multifix Tool Post
HTML-код
- Опубликовано: 9 сен 2024
- I'll share how to properly modify a lathe compound slide for mounting a PeWE Tools Multifix type tool post. According to the inventors of this style of tool post, you need to have the post body pulled down to a solid surface, not over a gap like you typically seen with the wedge styles.

I’ve been a machinist for 18 years and I still love it. That KBC is a really good little mill. Love the videos sir!
Right, these conventional mills are getting very rare nowadays.
Did the KBC sound a little loose somewhere? The piece got tight putting it into the key slot. Think there was movement of the vice?
@@rogerscottcathey no it’s not loose just the machine might be slightly tilting with the weight shifting as the table moves if the gibs have any slack. But that machine sounded good. I’d chock it up to the compound having a slight taper in the t slot.
As always, Adam's fit and finish are just beautiful. A pleasure to watch him work and see the finished product emerge.
Abom + multifix is a recipe for a banger video 👌
I think it's great to see a project of you making something. This is where you shine! It's like classic Abom. Luv it! Nice work, and the explanations are simple and clear. Nice narrative. Thanks for the great video!
I applaud standing!
You will hardly find such simple and excellent content.
Well done, boy. No show-offs, no extra words, everything is clear!
Bravo!!!
Adam, you made that drilling and tapping process for the T nut look so easy. In my experience, its always done with effort and with some trepidation ! Thanks for the video.
Love the silent intro sequence Adam. Pictures speak volumes.
You give meaning to the phrase competent machinist.
thanks of enjoying another Saturday night
Nice work, beautiful photography, class act. I am planning to get one for my old French lathe, now I know what to do. Thanks.
Superb work as usual. The Precision Matthews lathe always looks super concentric and stable. The effort you put into setting it up has produced dividends - the finish on the work pieces is outstanding!
Adam, I found out that my Multifix size E couldn’t stop rotating until I put the dowel pin. I used a M6 stud bolt as a dowel pin, as the fit was really tight and made it removable, which turned out years later to be the salvation for mounting my recently acquired toolpost grinder.
Your work quality makes me feel ashamed of mine’s!
Интересный и познавательный формат роликов!
Query, why did you not clamp your compound base directly to your milling table, sitting on your parallels?
Pulled down as like it would be in your lathe.
Wow Adam.... I'm green with envy of your shop, tools and knowledge. I've always loved to play with the shop lathes and mills at work... but I'm retired now with no shop. I''m sure glad I've got you to keep me interested in it Buddy! Cheers! Happy 4th of July !
Lovely work as always Adam and excellent filming
It will eat on you when measurements are so close you will break it down and make it rght. Awesome Adam
Adam your personal honor and commitment to excellence is always evident. Great work; every .003 thou counts!
Eric
But by lifting the one side by 3 thou he only needed a minimal pass in to the slide. Without that adjustment he would have had to go 3 thou deeper to clean it up all the way across.
Excellent vid. Professionally filmed as always.
Adam your videos are inspiring, such a lovely thing to come back to and watch after 6 hours of hard work, you really make my evenings fun to watch in 4K :D never stop, keep them coming!
Hello
Wow, awesome generosity from viewers. Ime sure everything will be cherished and put to good use.
Eye candybar, great to watch , even theraputic for me ❤

Since it was off .003, would it have been better to pull the oilers and mill the whole top? Great video and love the content!
Great work there Adam!
I reckon a new lathe is always exciting!
All you do, tools are cutting like its in butter. Amazing
Thanks Adam .. Best to you and Abby .
G'day Adam.. excellent video on doing the mods for the toolpost assembly
Excellent work and very instructive. Thanks.
Thanks for the show Adam
I'm suspecting that the 0.003" [0.0762mm] was well within the manufacturing tolerance for the compound slide housing. that's seldom a truly precision ground surface.
I'd be checking the bottom surface of the rotating base first a little bit more for parallelism and flatness, as that's a machined surface and can be slightly out since it wasn't ground.
Only after I was sure about the base would I go after the top, checking my setup as I go along.
Tolerances stck up (add up) so a couple of items being off by a few 0.0002" or so, plus some gapping, can add up to a couple of mils (thousandths of an inch).
Basically, it boils down to how close do you want / need the final result to be, and how much careful attention to detail you are willing to spend to get there.
Thanks for sharing.
turned out spot on Adam. beautiful finish as always
Well done sir ❤
Interesting content. Super filming. Thanks!
Quite a beautiful delicate work,Adam.Thank you.
Opinions are like assholes everybody has one. GREAT VIDEO Adam
Very good
You get all the fun jobs. Thanks for the video.
Thanks, Adam (and Abby! 😀 ). Happy Fourth!
Well before decking the top surface of that compound and T- Nut, I would set that
compound on your AA Starrett surface plate and run an indicator all over the top side
to see if it's parallel with the base.
Inspiring. Always a pleasure watching your craftsmanship.
Happy 4th of July Adam and to your loved ones😊
Great work as always !!!
Wow great work old guy!
Hi Adam you levelled the top of the compound but isn,t the bottom of it three thou out now.. I might be wrong trigonometry was not my thing in school ..anyway love the videos keep em coming
Potentially yes but thats ultimately irrelevant and wouldn't effect anything....so long as the bed ways are straight and true then parts will be true also.
High quality video, professionally shot as always.
Man! I can’t believe what great surface finishes you get Adam with the tooling and speeds & feeds you select. Really nice👌 And also, great video. I have ADHD, so with the way you create your videos, they move along nicely. So therefore it keeps my attention. With my ADHD, if videos are not concise and informative, I lose interest. Your videos keep me captivated….thankyou👍🙂
Loved watching this.
Thinking about the front to back 0.003" error, could that not be due to the gib tapers?
Brilliant Ricky!
you just reminded me of TOT Great job mate
Great video! Interesting point about the 0.003" off parallel. I wonder if the dovetail slides are also off parallel, or if they are true to the bottom. I would have checked that before deciding how to do the top with the new tee nut.
I also wonder if this technique might be advantageous when mounting other types of tool posts. I designed my own with a broad, circular base that straddles the slot in the compound but now I am wondering if this mounting technique might make it more rigid.
Adam's new ASMR channel :)
Beautiful work my friend....as usual.
Not a machinist and never will be, too old, but I been watching machining for several years now, enthralled with the ability to be sooo accurate. Like others, not understanding the meaning of the .003 parallelism discrepancy. @chemech and @ydonl have plausible explanations I can appreciate.
Who is the object of each sentence? Each sentence is incomplete.
Always Great to watch your work Sir
Станки конечно обалденные..
This is real technologi..good❤
17:15 could it be the moveable jaw has a little bit of lift to it?
@abom79, That was an Awesome Video Adam! As soon as I get my Precision Matthews 1660TL I will be hiring you to perform the exact same job for me. Great Job!
should you put a 3/4" set screw in before milling the top if you turn the compound around to let the back jaw dominate
as it does. the moving jaws likes to lift a little any way .you may not need a parallel on the movable side
perfeitissimo amei .muito lindo magnifico..super profissional.parabéns.sucésso e abraços..
Why wasn't the top of the compound, surface ground? I just subscribed with max bell.
Very good fit on the tool post thread. Thanks for the machine work.
Do you ever use thread gauges for checking the fits of precision threads? Otherwise, I will continue to view to see your work. I was a CNC machinist much of my life before retiring and I also had a toolroom shop at home where I did custom work.
See you tomorrow.
Nice product placement.
His speciality
That’s some dang good photography at the end
great mod man! you should really invest in a surface grinder
So, my question is, did you measure the thickness on both sides of the slide to see if it was the same? I can see why you shimmed it to replicate the top's original plane. But if it was out of parallel originally from the factory, wouldn't you want to correct that?
My theory is that that would be a big job, hand-scraping the dovetail. That wasn't the job he was asked to do here.
That surface doesn't need to be parallel
Nice little job thanks Adam
❤ Love it Adam.
Sorry for the question, I am still learning. Would it have made more sense to have gone with a coarser thread to the T-Nut, and a Fine 1/2" 20tpi for the hold down nut? The thread to the T-Nut was fine, but the thread where you want the most clamping force was coarse.
Nice job, agree with the shimming to get it level with the existing surface, as you have to assume the compound is probably in line when installed on the owners lathe. cheers, Dave
@@SteveColluns-hm2xx Hi Steve, he actually accomplished what the owner wanted him to do. he fitted a multifix toolpost to the guy's compound. The run out is his problem, maybe the owner should have been notified as to the .003" error, but thats another point, cheers 🙂
@@SteveColluns-hm2xx Ok Steve, I'm a retired machine tool fitter, worked for 50 years, If this was my lathe, I would certainly have corrected that error by scraping or whatever. I agree, if I had this job to do, I would have contacted the owner and asked if he wanted it correcting before I proceeded. So I do get you, should have just fixed it to the surface of the compound as it was, now I've had a long think about it. I've only just seen this channel, it came up on my feed, so don't know of his historical work practices, cheers, Dave
18:00 Since the part was so perfect in the vise, I would have shimmed up the whole vise.
Man I love me a big ol tap
Hope you stamped it A BOMB.
Really nice work.
F**k me the sound of those things milling like that is satisfying
Appreciate the good/detailed videos. I went to Walter's site to look at the external threading tool style you were using (vertical insert) and they don't show it as an item they carry. Maybe I just can't find it. Do you have a link for the external threading holder and inserts?
Do you think the 0.003 was from the dovetail? Did you try tightening the dovetail wedge?
You should really post a toolbox tour video, I’m curious to see what different types of tools you have
He has, many times.
Real craftsmen. Wow.😎
Wouldn't it be beneficial to use a Needle Roller Thrust bearing and Hardened washer, just below the flange on top nut?
Would actually direct all forces to increase downward force to tighten the Tool Post body?
Try to use a a SUBJECT as well as an OBJECT to your sentences. Othewise you're unintelligible
No, it’s hard to beat hardened steel against hardened steel for rigidity. Since very little rotation is required no roller bearings are needed.
@@silasmarner7586You might be the only one unable to discern what he was talking about.
nice job adam & abby !👍👍
Facinating!!
Beautiful work as usual thank you for sharing
Adam I have been watching some of the videos that CEE have put up recently (I only found them this week), he does a lot of Abom sized jobs.
What's an "Abom iced job"?
Edited to correct, I hate this predictive text.
@@SteveColluns-hm2xx..and yet you are here. Talk about weird.
@@SteveColluns-hm2xx it's called a youtube channel. Shows some great skills, products and how to use them. Nothing wrong here. I watch CEE too. Love his content. These are two completely different business models.
@@dave.of.the.forrest They are indeed completely different, although they have similar follower count. But note Abom's video 6 days ago has amassed 89k views while Kurtis' video 8 days ago has amassed 1.1million views.
I watch and enjoy both channels, btw
Would have liked to see the base checked out on the surface plate.
nice hammer
Well done little brother!
Thank you very much... Lots of great info for me to use
Could the parallelism be affected by the gib not being fully seated? After all the drop shown on the indicator is on the same side as the gib on the topslide.
It should be square with the tapers in the gib, not the bottom surface of the cross-slide. I think Adam was probably right. I also note, it hardly makes any difference, because all it does when it is off is slightly change the tool angle
Hi Adam
What do you think of a thread micrometer?
Well done 😅
26:47 I don't think the center part is brand new, on this photo it's clearly visible that they had just re-cut the cone tip. The following straight shaft part is shorter on the "after" picture 😅
Perfect timing for me. I’m changing the tool post on my Grizzly to a better quick change. The T nut doesn’t fit, so I think that I have to make a new one. Do you think that I’m on the right track?
That's all fine and dandy , but where does the cutting tool go on the post ?
Adam, What- No surface grinder?
Nicely done!!
Good job. Could you give a demonstration of how to use this. Thank you.
Hi Adam, great video as per usual. Have you seen these fractal vices? It seems to me this tool would be in demand if someone was making them at a very high level of quality. Adam Savage recently showed one on his channel from China. I thought of your exacting practices with machining and you would be perfect to make one of these thing of the old patent and it make for some great videos.
Great video, great precision!! 🙂
