HTML-код
- Опубликовано: 27 сен 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- ruclips.net/video/75DhpzJrGKc/видео.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.
I think it is simply amazing that you can see so much beauty in these things made on a machine by a master machinist.
I've been following you for years on RUclips. 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!
That my friend is one nice piece of machining ...WOW...Thanks a pleasure to get to watch...!
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 🤣🤔
Very satisfying watching 4140 being turned, the finish is very nice👍🔧
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
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
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.
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 RUclips (plus he is Canadian) calls them "nut f**kers"!
@@ericreynolds74 I have a metric variant.
I Like the format of this video. straight into it. precise. and the extra content afterwards. nice job Adam,
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.
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
Just finished Part 1 in time to see part 2. I always appreciate seeing the project through on the same day.
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.
"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 the video Adam! It is very inspiring for machining enthusiast like me. Thank you for planting that machining bug in me!
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.
Fantastic video,Adam,enjoyed,looking forward to the next one.
Excellent job making the tool post. It's amazing to see how generous the community is.
Really enjoyed part 1 and part 2. Very satisfying to watch your videos. Thanks for doing what you do!
that would good video adjusting spindle bearings
I was a machinist for 13 years, kudos bro for efforts!
Your photography on these two segments is magnificent. Your vids are instructive and enjoyable.
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. 😄
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).
Hey, hey, Tulsa represents! Love everything you're doing.
Some days your the pigeon, some days your the statue.
pretty soon the pigeon wont have a statue to poop on
That was really nice of you to do that for him.
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.
I always love your videos.
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 RUclips, I make time for seeing it... 😉
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.
Great work Adam , I agree with ya . That flat machine work makes it way more stable !! ENJOYED
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...
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 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.
Great job, Adam. As always. An inspiration to the field.
Nice work! I look forward to seeing how those pirranha jaws work.
Absolutely a beautiful job Adam!!!!!!!!!!!!!!!!!!!!!!!
I like the way robrenz and Stefan do their mount much more solid and the extended length for an indicator is better too.
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)
That's a nice peice - good work Adam!
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.
Referring to the Instagram comment there is always somebody online who thinks they're a bigger expert. Fuck em. Do what works for you
Great video Adam. Always enjoy watching you work.
"Fit 'em all wrench". LOL! Love it
The Germans call that an "Englishman" :))
Learning new thing from watching your videos. Let all your secret out. For a young guys.
Very nice job ! The heavy leather apron is very nice also !
Wow, you really made the chips fly in these last two videos.
MMM-USA order placed!!!! thanks Adam great work as always
Great video 📹👍thank you
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.
Hi Adam .. Lots of good machine techniques and lots of shiny bits. LOL Great 2 part series, keep up the Informative video's .
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.
Brilliant job!
Wait, Abom sometimes looks like he doesn't know what he's doing? Are you telling me he's human like the rest of us? GET MY PITCHFORK!!!
edit: put the pitchfork back, he got a piston fit on a bloody tool post stud.
12:25 wow that's a long coiled shaving, it looks like you made a spring unintentionally.
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.
Another great job.
Beautiful work!
I've seen a couple of these installed by folks I "consider" machinist who installed this exactly like you did. Beautiful job. Screw arm chair machinist.
people are funny you. you did a fine job by the book. best for rigidity
Exceptional craftsmanship!
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 .
Great video. Excellent work Adam. Thank you for sharing.
Looks amazing sir. Hey, haters gonna hate. Who cares right? Thanks for sharing. I just got an original multifix myself off Craigslist. I’m gonna have to do the same for my lathe. Thanks for sharing.
Sweet video 👌
That should be a few episodes, what to do when a tool breaks, leave the machine settings alone and making a pass to repair the miscut thread was interesting
Who are these supposed experts who think they know better than the toolpost vendor? Speak up and name yourselves! And show backing documentation..
Vendors do not always know more than users about what can go wrong over the long haul.
I just take the compound off and replace it with a solid block to mount multifix holders on, you gain so much rigidity that you don't even need the compound anymore.
Wouldn't that make threading difficult?
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.
I understand the three 6 mm holes in the splined block are positioned such that it may be rotated in 3 degree increments,
Yes
You nailed it Adam.
Great work as always Adam, thanks for sharing 😁
Hi Adam glad you are good and filming, considering Covid 19 in your area!
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.
Lol Abom with the opening ear bleed thanks to the chop saw ;) cool vid thanks!
Great video sir haters will always hate grate jobs here
Hi Adam ive enjoyed your videos for years, but this one in particular cos you are so good everything just looks perfect and goes perfect. But this time the chatter on round grooving tools and breaking of the threading tip made me as an amateur feel so much better about my skills as that is what so often happens to me, nice to see it hapens to the pro's too 😀
As always Adam, Good Work my friend.
Sensacional, sempre um aprendizado a mais, gosto muito desse canal, mostra ferramentas e maquinas especiais, e serviços que nos dá uma amostra do que é precisão, parabens, ! João Marquezin, São Paulo, Brasil !
MMM-USA win the award for the best box of the year!! LOVE a patriotic company! They have earned my business with the box alone!
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
There’s always a know it all any thing you do BELIEVE ME.
Very studly! Great work! 👍😁👍
Snap! I see what you did there!
Nice job 👍
Technically they’re called an Adjustable NutPhucker
Another excellent perfect job!!
Hey Adam, love your channel, I'd never seen a shaper until I saw yours, and now I gotta have one! Well, some day... Anyway, I wanted to mention that at 29:46, you started talking about drilling a new hole for the dowel pin if necessary. On the Pewetool website, it says that the three 6mm holes in the tool are spaced so that instead of just having 40 possible positions, you have 120. That should reduce the need to drill a different hole for the dowel pin in the base.
Could still be 1.5 degrees out in the worst case, way too much for parting, and especially unusable for a Morse taper holder
I'm not sure if you pointed this out, but the three holes for the pins are vernier-offset so that you don't get 40 positions, but 120 positions, which should probably be good enough for you to get lined up for your 30º cross slide.
Glenn you seem knowledgeable on this subject, what are the advantages and disadvantages of this type of tool post
@@jody6121 Hah! Nope, not really knowledgable. Just a good eye for details, I guess. I don't have any big iron, so - as far as I know - the Multifix wouldn't fit anything I might buy. First, for context about Multifix, their mission statement is:
"Focus on the parts industry".
Definitely not marketed to hobbyists. Multifix's website - www.createtool.com/list.asp?cid=33 - totally sucks for figuring what they make and what it would fit. That said, the big advantage that I see is that you can reposition tools at precise angles. The possible disadvantages are:
* I don't know how much non-professionals would benefit from this precision.
* You're stuck using Multifix tool holders, rather than standard dovetail tool holders.
* Note that Adam had to make hold-down stud for his lathe. I don't know how much of an issue this would be for other lathes.
Thanks for taking the time to answer....been watching Adam for a while now and always assumed this tool post was some old stuff that used to come on old lathes....not realizing that it was an aftermarket improvement....now I need more info so my wife can decide if I need one....appreciate your efforts and quick response.
@@tomgiorgini9154 might be a no when she sees the price....but I try to justify everything I want....but yes sadly she had veto power.
I don't need an incert to make me look like I don't know what I'm doing !
The "Deer in the Headlights" look, should be a dead giveaway !
Good photography, thanks
Wow.
You got a lot of new stuff.
