Vložit
- čas přidán 17. 07. 2020
- 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- czcams.com/video/75DhpzJrGKc/video.html
Ty guys, and sorry about my bad english (its not my native language).
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.
Is it only me who sees the irony of the massive chips hitting the vacuum cleaner 🤣🤔
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.
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!
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.
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.
That my friend is one nice piece of machining ...WOW...Thanks a pleasure to get to watch...!
I've been following you for years on CZcams. 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!
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.
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.
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.
I think it is simply amazing that you can see so much beauty in these things made on a machine by a master machinist.
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.
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
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 CZcams (plus he is Canadian) calls them "nut f**kers"!
@@ericreynolds74 I have a metric variant.
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.
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!
I Like the format of this video. straight into it. precise. and the extra content afterwards. nice job Adam,
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
Really enjoyed part 1 and part 2. Very satisfying to watch your videos. Thanks for doing what you do!
Nice recovery on the thread cutting, your experience is shining out.
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.
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.
Just finished Part 1 in time to see part 2. I always appreciate seeing the project through on the same day.
Thanks Adam. I have a Multifix tool post to mount soon so this video is very timely. Much appreciated.
Love the video Adam! It is very inspiring for machining enthusiast like me. Thank you for planting that machining bug in me!
Absolutely a beautiful job Adam!!!!!!!!!!!!!!!!!!!!!!!
Great work Adam , I agree with ya . That flat machine work makes it way more stable !! ENJOYED
Fantastic video,Adam,enjoyed,looking forward to the next one.
"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.
Yea good stuff... I really like that both parts come out back to back... Awesome!
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.
Those look like very fine vise handles, jaws, and cool boxes!
Love watching a Craftsman at work!
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.
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
Great job, Adam. As always. An inspiration to the field.
I"m so jealous of you getting to use all those great machines.
That was really nice of you to do that for him.
Great video. Excellent work Adam. Thank you for sharing.
i just Love these two parts!! Cheers!
Hi Adam, Every time I watch one of your videos I learn some thing . It is always a pleasure ! Thanks, David A. Bayer .
Great video Adam. Always enjoy watching you work.
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's a nice peice - good work Adam!
Hey, hey, Tulsa represents! Love everything you're doing.
Exceptional craftsmanship!
I was a machinist for 13 years, kudos bro for efforts!
I always love your videos.
Beautiful work!
Excellent work as usual Adam, love watching you work!
I like the fact that you do it exactly like the factory recommendation tells you to. Very nice job.
A pleasure to watch. Thank you.
Brilliant job!
You nailed it Adam.
Great stuff, Adam!
Making quality workmanship is one thing & the other precision
As always Adam, Good Work my friend.
Excellent work!
Your video gave me a very good inspiration. I like your video very much and have a lot of connections with our industry
Nice work! I look forward to seeing how those pirranha jaws work.
Nicely done Abom 79
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.
Very nice job ! The heavy leather apron is very nice also !
Fine job thanks again for your time !
Great video 📹👍thank you
Great work as always Adam, thanks for sharing 😁
Another great job.
Great video Adam!
that would good video adjusting spindle bearings
Good photography, thanks
Great job 👏
Great video!!👍
NICELY DONE ADAM !! 😁
MMM-USA order placed!!!! thanks Adam great work as always
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.
Great save on the threads. Thanks for the video. Now we will all know the proper way to install a Multifix tool.........
Nice job 👍
Adam,
An enjoyable video and a job well done.
Take care
Paul,,
Thank you Adam I always enjoy watching your videos I am from South Africa
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
Hi Adam .. Lots of good machine techniques and lots of shiny bits. LOL Great 2 part series, keep up the Informative video's .
Very slick job.😃
Adam, Awesome video great content really enjoyed watching great package nice vise jaws & handles, thanks for sharing your video.!.!.!.
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 CZcams, I make time for seeing it... 😉
Sweet video 👌
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).
Very studly! Great work! 👍😁👍
Snap! I see what you did there!
Nice job Adam!
Thanks for the info!
Another excellent perfect job!!
"Fit 'em all wrench". LOL! Love it
The Germans call that an "Englishman" :))
I believe being on youtube has been very good for you and I say it could not happen to a nicer guy.
Wow.
You got a lot of new stuff.
Nice job Adam.
