Lathe Compound Mods for Multifix Tool Post

[@RicksterX-92fs]

Nothing more entertaining and satisfying than precision manual machining! Nobody does it better!

[@Frankodilla]

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!

[@reinermiteibidde1009]

Right, these conventional mills are getting very rare nowadays.

[@rogerscottcathey]

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?

[@Frankodilla]

@@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.

[@josephford8884]

As always, Adam's fit and finish are just beautiful. A pleasure to watch him work and see the finished product emerge.

[@mfc4591]

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.

[@spdy3926]

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!

Excellent vid. Professionally filmed as always.

[@loydsa]

Lovely work as always Adam and excellent filming

[@marceloiannini8199]

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!

[@erichoff7926]

Adam your personal honor and commitment to excellence is always evident. Great work; every .003 thou counts! Eric

[@bertblankenstein3738]

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.

[@rs2024-s4u]

You give meaning to the phrase competent machinist.

[@bernardmauge8613]

Nice work, beautiful photography, class act. I am planning to get one for my old French lathe, now I know what to do. Thanks.

Hello

[@russbird8257]

Thanks Adam .. Best to you and Abby .

[@rickbcfl]

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.

[@joekanicki5306]

Brilliant Ricky!

[@EPaulIII]

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.

[@frfrpr]

Interesting content. Super filming. Thanks!

Excellent work and very instructive. Thanks.

[@can5projects563]

you just reminded me of TOT Great job mate

[@chemech]

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.

[@Doug_Edwards]

You get all the fun jobs. Thanks for the video.

[@UnderOpenSkies]

Do you think the 0.003 was from the dovetail? Did you try tightening the dovetail wedge?

[@PorchPotatoMike]

Nice product placement.

[@normandogrady2965]

His speciality

[@BorisLudwig]

I'm an inexperienced hobbyist so I might be overlooking something. However, I was wondering if you measured the compound thickness on both sides or, the vice slides that the parallels are sitting on to validate that the shimming is the correct answer. I have yet see the rest I'm only at the 19:34 minute mark. Enjoying the show.

[@scott241966]

I was thinking the same thing. I watched the rest of the video because I wanted to see if I was missing something too. Would it have been better to verify the the parallels are true to the mill, set the compound in the vice, then deck the whole compound? Then the top surface of the compound would be parallel to the bottom. Like you, I also enjoy all of Adam's videos!

[@firesurfer]

There was probably some leftover clearance from manufacturing. Too much work to redo the dovetail slot for a thou and half.

[@scott241966]

@@firesurfer I have been reading other comments about this video. One guy had a good idea...turn the compound over in the mill to mill the base parallel to the top surface.

[@olavmsonge5221]

All you do, tools are cutting like its in butter. Amazing

[@davejenner7966]

Thinking about the front to back 0.003" error, could that not be due to the gib tapers?

[@christianstark1055]

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.

[@johnjohn-pt7pe]

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?

[@silasmarner7586]

Try to use a a SUBJECT as well as an OBJECT to your sentences. Othewise you're unintelligible

[@ellieprice363]

No, it’s hard to beat hardened steel against hardened steel for rigidity. Since very little rotation is required no roller bearings are needed.

[@snowdog90210]

​@@silasmarner7586You might be the only one unable to discern what he was talking about.

[@davefuelling7955]

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?

[@ydonl]

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.

[@procyonia3654]

That surface doesn't need to be parallel

[@CameronMcCreary]

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.

[@patrickl6866]

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?

[@davidsnyder2000]

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👍🙂

[@nothing2loud]

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!

[@ronnydowdy7432]

❤ Love it Adam.

[@bulletproofpepper2]

Thanks for sharing.

[@petemclinc]

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.

[@phillipchambers8487]

@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!

[@edwardhiggins1295]

Opinions are like assholes everybody has one. GREAT VIDEO Adam

[@bobwilliams7343]

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

[@gaboonviper85]

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.

[@janosnagyj.9540]

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 😅

[@ARIFINLATHE]

This is real technologi..good❤

[@ggbogo935]

great mod man! you should really invest in a surface grinder

[@davidprovan2250]

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.

[@brettbuck7362]

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

[@sergioxavierdeoliveira3397]

Very good

[@ronmurphy9819]

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?

[@daveharriman2756]

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

[@daveharriman2756]

@@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 🙂

[@daveharriman2756]

@@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

[@wizardind3203]

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

[@halkuhns8070]

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.

[@silasmarner7586]

Who is the object of each sentence? Each sentence is incomplete.

you pointing out the pin holes is it possable to use out with the compound at straight at 30 dg and 45 dg instead of leaving the pin out and adjusting the post every time you change the angle

Why would you need to adjust the post? It has 40 positions you can use freely. The post itself never needs to be loosened ( I use Multifix on daily basis )

So glad you took care of the .003 difference. That would bug the heck out of me if you hadn't fixed that.

@@SteveColluns-hm2xx You sound like you really know what kind of machinist he really is.

[@Dreddip]

@@SteveColluns-hm2xx That's quite the leap. 548,000+ People would probably disagree with your sentiment. I've seen all but three or four of his videos, they're primarily about the process of machining and repair with a touch of machine restoration and light fabrication. Just because he doesn't do in-depth explanation on things few people feel require a high level of detail doesn't mean he lacks the knowledge. Small job shop machinists tend to have a better level of knowledge of what does and doesn't work in the real world than 90% of the rest of the world.

[@ydonl]

​@@SteveColluns-hm2xx Ah, i don't know. I like him. I suspect the 0.003 was in the dovetail geometry. It makes. a lot of sense to just leave it there, rather than embark on a crude compensation for it. If he has a whole bunch of spare time someday, maybe go back and make a change that probably won't make any actual difference in how the thing behaves. Hmph. People come along and think they know everything; sometimes I wonder if they're just trying to find a way to improve their own self-esteem. I also wonder if they're quite as perfect as they seem to imply. Another approach is to assume everybody gets a chance to do it the way they want, without a bunch of other people doing quite so much armchair quarterbacking.

[@richardjones-sl2zd]

@@ydonl Not his compound; it belongs to a client with an identical lathe. There, my self esteem has been improved. Pity no-one else in the real world gets to know that but not everyone has any interest in putting themselves out there; they just get on with the daily grind.

[@laurawerner]

Nice video. I'm going to need to do that for a new lathe soon. What size Multifix tool post do you have on that PM 1660-TL lathe you used in the video? I'm about to order the 1640-TL, and it should take the same size. (Unfortunately, PM doesn't have the measurements I need in their manual or on the web site, and I'd like to order the toolpost when I order the lathe rather than waiting until I can measure it.)
