- เผยแพร่เมื่อ 25 ส.ค. 2024
- We finish the Pewe Tools Multifix tool post mounting on the lathe compound by machining the center hold down stud. I'll share the lathe work, milling, and final fit-up. This was the size E tool post from Pewe Tools. They offer any size you could want, including parts and accesories that fit the original brand of Multifix tools.

I worked in TV for over 30 years and I thoroughly appreciate just how much time and effort goes into making these videos,. Thank you
Lots of time and effort for sure.
I also worked in television and your videos are very well done
P.S. I did both camera work and editing . A little more experience and you would do well in broadcasting .
Hi Adam , at the end of your videos you are pictured with your gramps and dad . What is the logo on your gramps cap ?
I am always impressed by his video work. He should give lessons to some studios.

Hi Adam :-)
I felt the need to add some information on the Multifix system.
The 3 holes in the body of the holder aren't 90° from each other, they are 93° from each other, the 2nd hole is 93° from the 1st hole and the 3rd hole is 186° from the 1st hole).
That means that there are 120 possible positions instead of 40. there are 40 positions for each hole in the body, the 2nd hole provides a 2nd set of 40 positions and the 3rd hole provides yet another set of 40 positions (3° intervals instead of 9° by utilizing the 2nd and 3rd holes).
Edit: With the 6mm locating pin set at 90° in the T-nut (90° to the length of the top slide), it's easy to hit 30° on the top slide and still have the Multifix tool holder parallel to the chuck just by using the correct hole in the body of the Multifix (since the Multifix allows for 3° increments and most machinists would agree that 30° works well for threading).
The T-nut for the Multifix really should be slightly below the surface of the top slide by 4 to 6 tenths. I did the same thing that you did but after using it for a few hours, I noticed that the tool post wasn't rigid anymore, turns out that I should have come up with some way of pre-loading the center of the T-nut before machining the surface, I should have made a set screw with the same threads as the center post, then tighten it down good before machining it (pre-load). The fix was to simply grind 6 tenths off the top of the t-nut, that took care of the rigidity issue.
BTW, I determined how much to grind off by using various shims between the body of the Multifix and the top slide, it held at 4 tenths so I decided to give it a little extra clamping power by grinding 6 tenths off the top of the T-nut.
Those jaws from MMM aren't reversible, the teeth are on both sides so you can clamp onto an internal feature as well.
The card that mentions "Don't break your teeth" is meant to prompt you to checkout their advice on proper use as well as drawings on how to properly machine your own soft jaws so their Piranha strips won't break.
They sell individual Piranha strips in various lengths for use on your own jaws (or fixture plates with cam type clamping systems).
Excellent work, my friend!!
Nice work on the video as well!! :-)
I'm always looking for new ways of doing things and I have learned a few new things by watching your channel!!
Much appreciated!!!
Joe
Great post. Thanks Joe! I had the same reaction to the T nut being (at best) flush.
One other point: if I was making a post for a larger sized lathe in particular, I think I'd go the extra mile and make the axle and the T nut one piece, ie a T bolt. At the very least, I'd recommend using Loctite High Strength Retaining Compound with the correct primer and a bit of pre-heat to make the stud as near as dammit a permanent fixture in the nut (you can always use a bit more heat, like maybe 180 deg C, to remove it)
Hi man I just want's to say that i am really enjoying all the videos that you make. I am 20 years old and I am watching tons of videos about metalworking from you and bench other youtubers (This old tony and NYCNC) for about 5 years all ready, few month ago I got my first mill and lathe and as I am working on them I realize how difficult it really is. Making good parts like you do is really a masterpiece. I learned so much from you and I really appreciate all of your hard work. one day I hope I will have good hands like you have! Thank you!
Good on you, I wish I had developed an interest in metal magic when I was your age. Adam doe's an outstanding job explaining and demonstrating his craft. His attention to the little details and pride in what he doe's really puts him a cut above in my opinion. Good luck and you'll get there if ya stick with it.
Awesome man! Learn some CAD/Drafting, welding and CNC programing while your at it. I was your age and into this stuff as well. Now I just keep saying ill buy a ,mill/lathe one day... ;/
Ty guys, In this days i volunteer as a mentor in frc team (if you dont know what is it search "First FRC" you really need to check it out) in the high school I learnt (and was part of the team of course). I teach them cad and mechanics. I really think passing my (little but something) knowledge to the next generation kids is the best I can do with my time. All the metalworking thing is just a hobby. But in the future i really need to focus about some cam learning. If you want to check my team robot's last year there it is- th-cam.com/video/75DhpzJrGKc/w-d-xo.html
Ty guys, and sorry about my bad english (its not my native language).
One of many things I've always admired about your videos is that you show your failures or accidents. You show more to the world at large than many of us would show to one person watching. You're a class act for it.
Love the multifix toolholder, Im in the UK and I have 2 Pewe holders on my lathes and am very impressed with the quality having had several genuine original multifix holders in the past. Just as a side note I have never put the dowel in ...especially when the machine is operated by others because if they crash the tool, it can move..this has saved me expensive repairs many times. They hold down real well with just the bolt. really enjoy your channel and the interesting stuff you do.
But you loose the ability to rotate the toolpost by an accurate and repeatable 3 degrees.
That my friend is one nice piece of machining ...WOW...Thanks a pleasure to get to watch...!
All that matters is are YOU satisfied with the method used. All the arm chair machinists are not doing the work. In Abom we trust!
What the customer needs, wants and pays for is what matters! The customer is always right even if they are wrong. If they are wrong and you get to make the right thing later, then you get paid twice :-). Great work Big Guy.
I have to say it Adam. The very last thing I ever think when I watch your videos is "this guy doesn't know what he is doing" haha. Keep up the awesome work, sometimes it's ok to blame it on the crappy tools!
Is it only me who sees the irony of the massive chips hitting the vacuum cleaner 🤣🤔
I've been following you for years on TH-cam. I don't do much with Instagram of FaceBook. Old dog, new tricks? Maybe. You have been very open about any error you may have made, so these "you didn't ... this or that..." folks should not bother anyone. Old adage from my many years in the Army.. "The right way, the wrong way, and the Army way." Do what works for you! I'm always impressed with the attention to the details that you put into every job, and the satisfaction you show in a job well done!
I think it is simply amazing that you can see so much beauty in these things made on a machine by a master machinist.
Don’t worry about what people say about how you do things. I always follow the manufacturer’s recommendations when possible. Excellent work as always.
for everyone that said he was doing it wrong.....get your own you tube channel and do it how you want!!
Exactly! I had one semester of machine shop and one of welding when I was in college for my mechanical engineering degree. Adam has forgotten far more than I ever learned.
Adam, the reason you're chipping the threading inserts could be another result of the loose spindle bearings that cause you grief with cutoff tools chattering on the Victor. The spindle bearings on my lathe got loose and it started murdering inserts left and right. Once the spindle bearings were correctly tensioned, no more chatter and no more inserts failing prematurely. And for what little my opinion on the subject is worth, I think a video or video series of you adjusting the spindle bearings on the Victor would be really interesting--the clutch and oil change series on the Monarch you did a couple of months ago certainly was.
Gotta love how the enginerds have to always second guess how anyone does anything. Enjoy your vids alot thanks for making them and passing on your knowledge.
Never heard it called a fit em all wrench. Round-all yes. now I have a new term. Thanks
All sixteenths wrench
One of the most popular contributors on TH-cam (plus he is Canadian) calls them "nut f**kers"!
@@ericreynolds74 I have a metric variant.
Adam, anybody can do that stuff if nothing breaks. (Well, not ANYBODY). But being able to recover the task after a failure of equipment is something you never see...thanks for all the hard work...
Thd difference between a trainee and a skilled man. The skilled man corrects cock-ups himself.
Yo tengo 4 años trabajando en Torno y Fresadora convencional. Y este canal me a ayudado mucho a la hora de fabrica piezas (me da muchas ideas) y ya ni mencionar la herramienta que muestra. Me gusta mucho este canal, un saludo desde México
Very satisfying watching 4140 being turned, the finish is very nice👍🔧
Mr Adam I’ve been watching you for about two years and I’m still amazed at the quality of you work and your videos. You can tell that you have many years of experience and that you pull from your fathers years of experience. Keep up the prefect job that you do
I Like the format of this video. straight into it. precise. and the extra content afterwards. nice job Adam,
I'm going to watch this a couple more times. I just love the way you process projects. I'm mounting the same toolpost. This is so nice to watch all the steps done right before I ever make a chip. Thanks Adam, thanks for being Awesome!
Concerning the alignment with the cross slide, the reason the Pewetools Multifixes have three pin locations is that they're offset 93°, meaning you can turn the tool post to a different pin location.
That gives you 120 positions by 3° instead of 40 by 9°, so you can realign it to fit your desired compound orientation and is one reason I replaced my import with a Pewetools QCTP.
Tools can make the absolute best craftsman look like they don't know what they're doing. Having watched most, if not all of your content, I feel confident saying that every person who has watched your stuff can tell you're a highly skilled machinist.
We use those jaws at work Takes a crash to dislodge the part from them. They make a dimple on the part so don't use them on a part that is fully finished. Awesome videos. Saturdays are always enjoyable watching your videos. Learn a lot from them.
Do you clamp tool steel with these by any chance? If so, how well do they work.
@@ianide2480 Steel and Alum Works well with both. O-1 and A-2
Not just anyone can start cutting threads and then change a tool bit and come back and pickup the thread and continue cutting and have that good of a thread when finished.
Very nice work.
Good tooling and good inserts certainly makes that easier.
Nice recovery on the thread cutting, your experience is shining out.
Just finished Part 1 in time to see part 2. I always appreciate seeing the project through on the same day.
Fantastic video,Adam,enjoyed,looking forward to the next one.
Love the video Adam! It is very inspiring for machining enthusiast like me. Thank you for planting that machining bug in me!
Cool stuff, I just love the way Americans have serious pride in their work and how they produce and present it. Lovely gear especially the vice handles. Nice work on the 4140 Adam btw.
Abom I've been watching your channel for a long time now an I subscribed . I'm new to machining an have learned so much from your video's , Thank you for that... These people who post their comments about how you should have done things, probly don't even have a shop. The reason I watch your video's is cause its obvious you know what your doing an have many years experience . Thanks again for sharing your skills.
that would good video adjusting spindle bearings
"Make you look like you don't know what you are doing" said Adam. No one else on the planet can be found to agree with his statement.
Love watching a Craftsman at work!
Really enjoyed part 1 and part 2. Very satisfying to watch your videos. Thanks for doing what you do!
Thanks Adam. I have a Multifix tool post to mount soon so this video is very timely. Much appreciated.
Thanks for sharing another great video with your precision work as always!
Excellent job making the tool post. It's amazing to see how generous the community is.
I was a machinist for 13 years, kudos bro for efforts!
I like you're method of mounting the T nut as you don't need to modify the cross slide. I try not to drill holes etc. in my machines unless I absolutely have to (e.g. mounting the slides of my DRO).
Adam mate you seem the most easy going, placid guy on earth. But I thought you were gonna swear when that second insert chipped!
Just what I thought. chuckled at that point
Those look like very fine vise handles, jaws, and cool boxes!
From Peter: Those 3ea 6mm index holes on the bottom divide the 40 positions ( 9° each step) into 3 different offsets at 3° each. So if you move into a second hole from where you start you have 40 more positions offset by 3° from original 40 positions. Then if you move the post into the 3rd 6 mm hole you have 40 more positions offset 6° from the original toolpost position. It’s slick method to turn 40 positions into equally spaced 120 rotational positions. So it’s pretty easy to get really close to being square to the spindle at any compound angle setting.
Jorg Jorgensen Peter loves to chat. I think we covered every aspect of his system. He wasn’t hip on me doing the t-slot mount with the Jack-set screws but I showed him my method on my install. Now it seems Peter is comfortable enough to pass on this method to others. He really promotes the European method of installing a fixed stud in the compound so that the etching on the bottom of the post actually completely embeds microscopically into the compound to make a rock solid 100% contact. I suggested my method of very tight fitting T-nut with large jack set screws and then surface grinding the full contact area as Abom did. It works. I found it impossible to rotate my post using a 1/2-13 stud and nut out of a Teco clamp set. It’s a great product and can very successfully be used on a t-slot compound of American and British lathes. Thanks for your reply. 😄
Making quality workmanship is one thing & the other precision
I like the fact that you do it exactly like the factory recommendation tells you to. Very nice job.
That was really nice of you to do that for him.
Your photography on these two segments is magnificent. Your vids are instructive and enjoyable.
Always impressed by the quality of cut that Metal Devil saw leaves.
Just like the die grinder the sharp little chips are designed to cause maximum pain.
armchair critic here... I think I would have cut the flats n the smaller section, since it has nothing riding on it. If you put abom torque on it, you may deform the close fit surface that fits the tool holder...
Just once, Abom, I’d like to see you f up your initial scratch pass for threading, and prove to us that checking it with the pitch gauge before proceeding, is worth the time. After watching dozens and dozens of your vids, I’ve never seen you miss it....
Was thinking exactly the same. Everyone says the same, Joe Py, Stefan and Abom, but I have never seen them stuff it up. I guarantee that if I was cutting threads, the first time I didn't check would be the first time I stuff it up.
Then again, I'm definitly not in the class of these guys, just a hack.
He did once, and screwed up an expensive job. Maybe a prop shaft? He talked about it in one of his early videos. He tried to fix it with a custom nut, but his dad decided to scrap the part and start again.
I am not a machinist but from what I've seen here and on other channels you have to change various gears at the drive end for the pitch you need so I GUESS IT IS EASY TO GET IT WRONG. A 5 second check with the guage saves the part you are working on.
@@ericmcrae7758 Yeah you are right. I have one of these lathe and it is a real PITA. Blondiehacks has the same one, which is probably why she nearly always uses taps and dies. I think Stefan has the same. He even cut his own gears to do some weird thread pitch. he may have got it wrong once, but I suspect the even he doesn't remember that
@@ericmcrae7758 Depends on the lathe, I seem to remember that the Victor he uses here has a quickchange gearbox and change gears are only used to switch imperial and metric, though I'm not totally positive on that.
I believe being on youtube has been very good for you and I say it could not happen to a nicer guy.
Nice work you're doing, and I am happy to see that your proud of your work, and your work is great.
When you are milling fore the 1 inch wrench, the chips were flying and smoking like little rockets...nice footage you make of your work...top 👍
Every time a get a message that you made a new video on TH-cam, I make time for seeing it... 😉
Don't ya just love armchair engineers? LOL! Adam, do as you were informed and let the other homechair machinists just talk. You do it right as always. Has been a great video from start to finish on this. Waiting on your next project to begin - thanks for sharing & stay safe.
Hey, hey, Tulsa represents! Love everything you're doing.
Man would I love to see some blooper reels from this guy...Must be some good laughs in there somewhere...
New tool post only two weeks wages . Ouch . The Australian dollar ant to good ! How does it compare in your country out of interest
I don't think he make enough mistakes to fill a blooper reel.
You made a little comment that someone might think you don't know what you are doing?? No one could ever draw those conclusions from watching you at the mill or lathe. You are a master!! Perfect? No, but nevertheless a master I enjoy watching. Been 50 years sinse I ran a Bridgeport, so I love watching a master, thanks!!
Adam the fact that you catch a bit chipping out so fast proves you "do" know what your doing, much better than most! No worries buddy 👍😁!
Some days your the pigeon, some days your the statue.
pretty soon the pigeon wont have a statue to poop on
Yea good stuff... I really like that both parts come out back to back... Awesome!
I'm digging the leather machinist smock/apron
FYI, about the pin, I installed mine without it and it worked fine, until a couple of weeks ago when I was doing an interrupted cut boring cut. The post would not stay in position. Now its pinned and fine. Nice video(as usual)
Hi Adam, Every time I watch one of your videos I learn some thing . It is always a pleasure ! Thanks, David A. Bayer .
I always love your videos.
Nice work! I look forward to seeing how those pirranha jaws work.
Adam, Great job man, as always spot on.
As far as I am concerned you are a very knowledgable and excellent tradesperson.
Why do you give these trolls a mention, that's all they're after. They haven't the ability to create anything themselves, it's easier to try and tear you down. Don't give them airtime!!!!!!
Sorry for rambling but all true.
Great work Adam , I agree with ya . That flat machine work makes it way more stable !! ENJOYED
Very nice job ! The heavy leather apron is very nice also !
You do very nice work my friend, And if the customer wants peanut butter on it and you put peanut butter on it you did what the customer asked don't matter what others say.
That's a nice peice - good work Adam!
I like the way robrenz and Stefan do their mount much more solid and the extended length for an indicator is better too.
Great save on the threads. Thanks for the video. Now we will all know the proper way to install a Multifix tool.........
That 'Don't lose your teeth' sticker cracked me up. :)
Woo hoo, Abom79, This Old Tony, Blondihacks, I did a thing, all on the same day.
"Fit 'em all wrench". LOL! Love it
The Germans call that an "Englishman" :))
Great job, Adam. As always. An inspiration to the field.
Great finished project Adam, looks like it’s going to do the job as asked for. 👍👍. Nice product review at the end of the video also. Good to see the Made in America Products that are actually made in the Continental United States 🇺🇸. Thanks for sharing with us. Fred.
Absolutely a beautiful job Adam!!!!!!!!!!!!!!!!!!!!!!!
I purchased a PeWe size A for my Hardinge HLV-H. I machined my Stepped Bushing Stud with a through hole and used a socket cap bolt that matches my Hardinge compound tool rest swivel lock down socket cap bolt 3/8-16.
12:25 wow that's a long coiled shaving, it looks like you made a spring unintentionally.
Adam ,
Great job , if you follow the manufacturer's directions, any issue is on them . Opinions in replies , including mine , are like certain body parts , everybody's got ONE .
i just Love these two parts!! Cheers!
Referring to the Instagram comment there is always somebody online who thinks they're a bigger expert. Fuck em. Do what works for you
Any time when you cut on both sides of the insert your gonna get chatter. That is why when cutting threads you turn the compound at 29.5 degrees. Your only cutting on one side of the insert.
I"m so jealous of you getting to use all those great machines.
Great video Adam. Always enjoy watching you work.
Hi Adam .. Lots of good machine techniques and lots of shiny bits. LOL Great 2 part series, keep up the Informative video's .
Excellent work as usual Adam, love watching you work!
Thank you Adam I always enjoy watching your videos I am from South Africa
Learning new thing from watching your videos. Let all your secret out. For a young guys.
I wonder... since the OD adjacent to the wrench flats is such a tight fit, isn't there a risk that a wrench will roll or mushroom the sides a bit and ruin the fit? Wouldn't it be better to turn down that OD at the wrench flats so that they never cause that kind of problem? Not a machinist, so set me straight if I'm wrong here.
You are right, but Adam deburred the face edges. That should prevent the problem you foresaw. If it were to "bell", the user could simply file the high spot down again. In any case, that stud won't see many "fitting" cycles - install it and let it be. Hope this helps.
@@michedmck makes sense.
MMM-USA order placed!!!! thanks Adam great work as always
Carmex tailn coated thread inserts with no chip breaker are the best I've ever used hands down on steel. Iscar honestly the worst either to brittle or don't hold an edge. I'll find out what grade and send it to you to try
Your video gave me a very good inspiration. I like your video very much and have a lot of connections with our industry
Wow, you really made the chips fly in these last two videos.
Brilliant job!
people are funny you. you did a fine job by the book. best for rigidity
I think it those loose bearings in the headstock breaking those inserts.
From the top view you can see the part flex
I try to always use a live center, in the tailstock, when threading.
Adam, thanks for answering my question on getting the multifix square to the chuck when the top slide is set to about 29.5 degrees! I ordered some tool holders from Peter earlier this month but they've been stuck in Frankfurt for the past few weeks. Can't wait to get them.
Nice job, who are these Instagram trolls that say their should be an air gap? The care package at the end of the video, that company even made the vice handles red, white and blue.... nice job.
