Turning Weld Build Up With High Speed Steel

- This a quick machine job on a stub shaft that goes in an axle assembly on a fork lift. The seal journal was severely worn down, so it was welded up and I had to machine it back to size. I use some Rex 49 high speed steel to turn this, and show how these tools are excellent for turning down weldments.
This is the first video I made of the same types of repairs done to the forklift axle.

I have been a machinist for 37 years. When indicating something like that I always use what we call a brass bumper. Its just a piece of brass about 3'" in dia. and about 8" long. I always bump directly towards the indicator but I always pull the stem of the indicator back while bumping to avoid damaging the indicator. Then let the indicator touch again and in this way you can tell if the part moved and how much without even turning the chuck around. This is especially handy when indicating large jobs such as 35" dia bronze bushings.
It is so good to see that the "younger generation" have been passed the skills that we used on a daily basis back in the stone ages.
Thank you for sharing - brought back memories of rebuilding tractor kingpins back when there was no MIG (only stick) and welders ALWAYS dumped the part in water to cool them down.
I do alot of metal build up using stick welding
In my case the guy left pockets of flux all over the place AND tempered the piece by quenching it in water to cool it down...
Adam, you are a real inspiation to me.
Started machine work when I was about six, under my Dad's supervision.
Your videos bring back fond memories of those times.
Didn't know then, how big that learning curve was. I'm 52 now and still learning.
Dad still teaches me things, as do you.
Thank you.
My grandfather ran a Monarch very similar to that one for 25 years. About a year before his transition he was 90% blind and I took him down to the plant where he was a machinst to visit one last time...even unable to see he described every function of the machine to me while we stood there next to it. It's very nice to see one of these beautiful machines still going strong. Thanks.
+STKTNC Wow what an awesome story of your grandfather!
This video really brought back some unexpected memories. Thank you again. He would have loved yours and Keith's channels!!!!
Great story.
That lathe and that chuck embodies the definition of deluxe and luxury. The impressive results speak for themselves. I'm not a machinist and likely never will be due to the cost of the machines, but the joy I get out of these videos is the transformation of before and after. It's awesome to see what's possible when you have a skilled tradesman at the controls.
I love that old Monarch, it was built with so much excellent engineering.
Looks like a new part. I worked in a factory that had mostly 50-100 year old machines (made wire). Those guys kept all those machines running by constantly rebuilding old parts. It was magic to me how they did it, and now watching you, I can clearly see it is magic.
I miss this relaxed format. So soothing to watch.
of all Adam's video subjects - viewer mail, cooking, building projects, trips, new machine welcoming, I like the shop machining vids the best. utterly fascinating. amazed with this man' knowledge and accuracy
I'm a Aerospace seal designer. I really enjoyed this video. :) We always recommend at least a 15 degree lead-in chamfer so the seal will not be damaged upon instillation. I'm glade you talked about this. People always ignore that and destroy the seals upon instillation. Also surface finished is super critical for long seal life. (80% to 90% bearing ratio if possible). If the seal is tearing up the shaft maybe you could heat treat your shaft post machining, or chrome plate it. Thanks for this video.
When you're putting in your valve oil seals on your Harley heads, go down and buy yourself a bottle of vitamin supplement capsules near enough to the size of the valve shaft, open them up, tip out the powder, oil them up and then slide them up and into place. The amount of times in my younger days when grinding valves on cars that I'd punch a ring in that new rubber seal with a sharp valve when putting it back, if I'd had a dollar every time, I'd be rich today. And disengaging the half nuts when Metric threading is child's play if you learn the simple technique..... Just saying.
We used to spray ceramics on seal diameters which gave them a long wear life.
@@garyd5622 Newb here could you explain that ?
@@eflanagan1921This video illustrates the spray welding. Different powders will give anything from bronze to ceramics. We found it cheaper and faster than replacing the whole shaft or spindle. th-cam.com/video/ByeLJsHvnzc/w-d-xo.html
@@garyd5622Thanks, I didn't know about that either,the vid was very good-I noticed that abom70 has 2 vids titled shaft metalizing which I think is the same thing but in more detail.
Went back and watched the old video. I have been a long time viewer, but reviewing that old video, I can see how much your video professionalism has advanced! Great job.
Great Job, Adam!
A work colleague used to joke that graduate engineers work to tolerances of a thousandth of an inch but the master metal workers did it exactly right.
I do machine work and I have been a welder for machine shops for some years. When building up parts for machining clean, I've found I need to build up a lot more than seems like enough if you really want to avoid surface defects when machined to size. Dual shield wire with some post heat and slow cooling makes a more machinable weld deposit than hard wire.
I think many of us sat and snickered when you put the Abom Torque on that part and then kept bumping and thumping it and it wouldn't budge. LOL. That new chuck is a skookum choocher for sure!
Great vid buddy! Thanks!
Oh yea, it's a good chuck and I love having and using it already
That little smile when you mentioned "using the new 4 jaw chuck".........You can see the excitement at getting to play on the lathe!
old school machinists are very rare these days...i salute you sir!
Prior to finding your channel, I never appreciated the precision with which machinists work. I'm impressed.
Artisan. The gentleman that performed the welding did an amazing job not adding more material than necessary. I can tell you boys have been doing this for at least a month now.
Great lesson. Knowing how to machine rework and repairs are skills that will always be useful no matter what. Thank you for teaching this.
What a wonderfully silent machine.
The Monarch is a nice quiet smooth running lathe.
Its friday night, im getting over my work week and im here. That monarch really vibes with me...
Yeah! Very well maintained lathe machine...
As a fellow turner, I have to say there is something really satisfying to take a crappy welded part and make it look like new. Well done sir.
The new chuck looks and performs great. That nice lathe has been made even nicer!
New tools are always fun to play with. It's even better when you're impressed with the quality. Great watching you work.
You're the Jedi master! Using the Force to true up a piece like that is bloody magic!
hey adam nice job. about a year ago i got a call from my buddy that owns a scrap yard and fab shop. he said a machine shop had just scrapped a bunch of strange tool holders.thanks to your video i knew what he had. there were multi fix. i got two tool posts and about 30 tool holders. i changed over from my aloris and never looked back, i modified the tool holders to use five 5/16 allen bolts it comes in handy when using short tools.
Wow! What a score!
Wise find!
Let’s all play the ABom Go Ahead game! Every time Adam says Go Ahead, take a drink, or whatever your vice is, and you’ll be feeling good by the 5 minute mark.
That Chuck is so badass it should be named Norris
justen sr, Your a funny guy.
@@scottcarr3264 I guess I'm too old to be a fan boy!
This made me chuckle a little bit.
...GET A GRIP-!!
Old style 4 jaw chuck
The repair came out lovely and clean I would be well happy with that.
Great work, Sir
you make it look easy, that's the difference between a journeyman and hobbyist.
Repair work is never as easy as new parts with prints.
Thanks for sharing.
Good job. Enjoy watching your videos. Like to see a person that knows what he is doing..
Love how 'silent' the lathe is while running, makes for a friendly work environment! Another high quality machining job!

That lathe's headstock has helical-cut gears in it, just like you would find in a conventional automotive manual transmission or semi-truck manual transmission. They do a lot to cut down on gear whine and gear noise. ^^
Patriot1776 If he wants a comparison, he should jump over to Keith Fenner's channel. His engine lathe has straight cut gears and does have some gear noise at higher speeds.
I like using HSS on when turning back welds and also when turning rough castings. I find the inconsistency destroys carbide tools.
I wish i could get my coworkers to do the same thing, but 100% of the time the forst carbide insert tool that is seen is grabbed and put to use, then its destroyed, and another insert installed, instead of taking a little more time to use a tool bit.
When I was an Apprentice and worked on a leblond engine lathe I found that when I used an inserted carbide cutter to rough and finished with my high speed Steel I would get a very repetitively cut, finish my finish size was spot on.
my man you the Picasso of machining it is art that you make
Those are my favourite videos the weld build up ones, thanks for sharing
+The Funeral Director 1965 cool glad you enjoy
Always enjoy your videos. That machine is so quiet , must have foam rubber gears in it ! Thanks for taking the time for us out in you tube land.
Impressive results dude, you're really skilled in this art!
Thank you
I bet you could even teach bloomberg a thing or two...that fn pud thinks he is better then anyone
@@douglashanlon1975 it's simple. Just turn the crank in the direction of the arrow and you can have a job!
Another excellent job. This guy is a true machinists.
Of all the machining videos I've seen, And I've see possibly hundreds besides yours, you have the smoothest lathe. Usually you hear the gears mesh and whine. Love the videos, I've learned a lot.
Coming from Air Force metal's tech. We have 3 lathes with a brand new one still wrapped up.. Video showed some interesting things.. having a compound rest that has notches for degrees must be a bliss rather than having to loosen 4 nuts and then judge degree based of a line Mark at the base of the compound rest
I love those T-Rex forklifts. Big, Strong and aggressive, but the only issue i have with them is the 10 inch fork length....... (ok that's a bad joke)
But funny...
really enjoyed this video mate, its great that you make the time to share your knowledge with all of us. thanks
after i put the part loosely in the chuck I always use my tail stock to push it flat and then get out the the indicator usually gets it pretty close as long as that front face is true as well.
you should tap a cutter blank and attach a bearing, making a bump centering tool. you just turn the machine on low and bring the tool into contact and the work will just straighten itself out. not perfect but it gets really close really fast.
Thank you Adam for sharing this tips and tricks.
Ahh, the old Brown & Sharpe 1-2 mic. Love 'em.
When you say a measurement looks good to you I assume light won't pass between the micrometer and the surface you are working on. Love it!
Man after dealing with G code and programs all day long its nice to go back to the old school stuff. Its just so much more fun.
Absolutely fascinating, incredible skill and attention to detail, something i fear is slowly being lost! Just the use of proper engineering hand tools, run out guages, micrometers and verniers, Brilliant ! Reminds me of my youth and sheet metal work (of course not working to such tight tolerances)
Good job as always. I do agree about the use of tool steel instead of carbide on a interrupted cut. I do enjoy watching your videos .
Abom79. .. I could watch these all day. There are a lot of milling/lathing/metalworking videos on YT but I love how you take the time to explain everything and you are truly a master craftsman with great quality ethic. Keep up the good work!
Love your videos. No nonsense, pure machining craft.
Excellent educational setup of work prceedures. Will enjoy this channel.
This video looked and sounded so professional to me. Granted I would expect no less from Adam. I would say this should be on TV but then I would fear his content would be diluted by corporate entities.
Best thing to do is guys like me just keeping on doing it our way. Corporations didnt help us get to where we are, except for TH-cam allowing us to upload our videos here.
Yep for sure. Keep up the great videos.
That’s real close to what I am needing to do. Buddy needs a spindle built up and re threaded. They are expensive for him and hard to find at any rate. Plus it’s a project. Tig weld and turn.
Thanks for the video
next time you use wire wheel turn work piece opposite direction at 3:00 so you are not throwing trash on what you have already cleaned. i know its not crucial but if you do that you can see what is clean and save time.
always love that 3 generations pic at the end. giving credit to the forefathers
Pure art in the making! Thanks for sharing your knowledge sir!!
That Lathe is a hoss. I'm digging how quite it is for the amount of power. Very skilled operator. I have a 1933 South Bend 9" that runs on leather belts and is a joy to run because of the noise factor. You can hear the chips peeling off a .003's clean up. My big lathe is noisy and have to have ear plugs. Awesome job Adam.
I agree!
Helical gears in the head are the secret in Monarchs.
Adam thank you for Cher you time and show your talent as machine i like to learn everything you show one more time thank you and thank you
You would make a great teacher. Thanks Robert
Looking like a nice part again, Adam. Enjoy the rest of your weekend.
I've noticed a few things that I've learned from you Adam that I do now! So grateful for you sharing your skills.
Now I just need to learn to make my video's better!
Thanks, Razor!
Thanks Ray!
I never thought to use a caliper to indicate height. Thanks! A co-worker and I got an old mill-drill running at my work place, and I was looking for a height gauge. Somebody bought a dial calipers, so this is one more measuring tool I don't have to convince them to buy....
I'm pretty new at machining and my first attempt at machining weld build up went pretty bad lol (wrecked the piece and it flew out of the chuck 😬). So thanks for the tips. Also, liking that tool geometry on the hss. Still rocking a lantern style tool post so that will save me a lot of time changing tooling 🙂.
Thanks for the video 👍😀👍
Dude you indicated that piece like one's business.
Just over four mikes
I assume the part was welded by the customer? You do an excellent job of how welds are turned by HSS tool bits. I'm old enough to remember when there was no carbide, at least where I worked, so HSS was all there was. I would like to add that if it was my choice of how to repair this part...because it was a seal dia. welding would have been my last choice as the risk of holes and the apparent soft wire used would result in a very short life for the seal and journal. My first choice would be to turn the part back and shrink a piece of 1045 or 4140 with a wall thickness of about 1/8" and finish turn & polish to size. Just sayin'
I agree. A sleeve is the best fix. Polishing a bearing journal will cause the bearing journal to be undersize.
This was really good to see, always thought adding material using a welder then machining was a bit of a myth, but goes to show it can be done quite easily
That new chuck is looking awesome!
I like how you show the different ways of measuring with the same tool. Don't want the wife to see that though. Gotta make me some more purchases.
Great job. Appreciated the detail.
I barely know which end of a screwdriver to hold onto, but I very much enjoy your videos! I learn something new every time I watch one. Well done!
I always like hearing from viewers like yourself. I have so many who are not into machining but still enjoy watching.
Just listening to all those fractions makes my head hurt, long live the metric system! Nice job! My ocd is killing me with the shiny one vs the dirty one :)
Great work as always. Those jaw teeth reflect light so nicely, look very strong.
miss seeing the monarch, what a beaut.
Awesome repair Adam! Had something similar come through my door 2 weeks but it was a hydraulic valve with rust pitting.
Adam, years ago I think i saw this in the HomeShop machinist. piece of stock about 4x1/2x1/2 and mount a bearing on the front end. mount in a tool holder for the qctp and use it to push things concentric. use it on the y axis and flip it for the x axis. watch you all the time man, great fids.
Always a pleasure to watch your vids. Top notch work as always.
I saw you liking that chuck just before you said it. Nice.
Oooh! That's a new chuck! So shiny!
I didn't think hss would handle it. Maybe i've seen too many welds go hard. Nice work.
Chuck looks great, sounds like its working great too. HSS is still really good for certain jobs.
Really helpful, thanks for going step by step.
Another great video. That chuck is a real beauty!
I have been doing my own machining for a while but just cannot get the hang of grinding my own high speed steel. I wish you were my teacher etc.
That chuck is sweet and the lathe is quiet! Got the T-Shirt and it get's some eye's!! Keep the Vid's coming!!!!!!!!!!!!
+Gayle Strand Thanks for the support Gayle!
nice video, one quick tip that i use is to take a pair of precision ground parallels and put them on the face of the chuck behind the part and use that to square up the part. is can save some time.
Very nice work looked great!
Nice Chuck! Really turned out well. Those jaws have some real grip!
Wow, that chuck looks real nice. I saw the videos where you cleaned it up - it really pops!
Nice Video Adam, Thank you.
I've had to turn M.I.G. welds on lathes plenty of times. The welds are almost always soft when welding with a 1018 steel filler. If that piece is cast steel, it should've been welded with a stainless wire for strength. But to me, that piece looks like it was machined from a solid chunk of steel. That is a nice looking chuck too, by the way! I had to give up machining and welding due to 4 spinal surgeries. Good video though! I enjoyed it!!!!
I hope your suffering is completely gone by now!:) I have an idea of what you are talking about... Keep it up!!
Do you mean "7018" instead of "1018"? The latter is an AISI grade of steel while the former is a category of SMAW welding electrode under the auspices of the AWS. 1018 has a limited manganese content and virtually no silicon, whereas most weld fillers have 1-2% manganese and 1% silicon, but generally less than 0.1% carbon. Carbon does bad things to welds. Even still, Conditions during welding can sometimes cause spots with unusually high hardness, often due to particularly high shrinkage or very rapid cooling. In terms of composition and mechanical properties, weld fillers tend to have much more stringent requirements. They're generally required to have both greater strength, and ductility/elongation than something like AISI 1018.
The chromium in stainless causes it to be soft not strong it’s easier by far to damage that most other steels it would never add strength
I'm always impressed at how quiet the Monarch is. In comparison to Keith Fenner's Clausing.

Hey Adam, nice work. You did an outstanding on cleaning up that chuck. I went back and watched your chip control vids and plan to start using HSS tools more now . you and Tom Lipton made it easy for me to understand. Thanks . I do this as a hobby and I believe you said they are better for small lathes like my 7x12. Thanks Dave
+David Aarons Thanks David. Hss tools have been around a long time and they still get the job done just fine. Once you learn some basic grinds you'll find that using them can be a joy.
Great job, you never know with welded parts, sometimes they are not hard and sometimes glass hard.
hey adam, i love the videos. dont know why but for some reason metal work just brings a smile to my face keep it up!
Nice part and vid. A hefty 4 jaw chuck there and a massively stable machine :-) I'm learning to machine my welds on a typical small china lathe - when necessary - a new addition - so your vid is helpful and kindly to machinist fabricator 'heads'. Thanks and have pleasure with the tools and transformations.
As usual great video again Abom, and again I get to suffer from wanting a workshop like yours in my life
Nice job Adam! New chuck looks awesome.
An old Slocomb depth micrometer! I have one but it has a little catch as it turns when cold.
