Machining a New Barrel Nut for a Hydraulic Cylinder - Manual Machining 

As a hobbiest, I really appreciate you taking the time to make these videos. I don’t have a mentor or any friends that are machinists, so these types of videos are where I get to learn. Cheers

Watching turning operations is just plain therapeutic.

That's the first time I have seen that trick to re chuck a nut for threading, thank you for sharing your knowledge and experience.

That Monarch lathe is a BEAUTIFUL piece of machinery.

I remember that my dad's 'brand new 55 Chevy Belair had rust on it and the dealer said it was just from the transport from the factory to the dealership south of Chicago. By 1959 there was little left of the car. I really love that Monarch lathe. Nice job as always on that nut.

22:02 Man it must be so satisfying when it spins on first try!

Goes to show why wearing short sleeves is important, the lathe always wins when it decides to grab hold of someone's loose clothing. Another good video!

It always amazes me that threads are able to be cut precisely with each pass, with the cutter beginning in exactly the right place. I can't even put the lid on a jar of peanut butter without cross-threading it.

You are the only engineer that i have ever seen on spuw tube that has the same ram cap experience as me , usually gas axe grinder teleporter and lots of swearing .

That scriber trick for checking the thread progress is genius, very simple. Never seen it done before. Great work!

"Every once in a while, a blind squirrel finds a nut!" This was great to watch Josh, thanks for taking all the time to have us along! P.S. AnchorLube is about $45 a gallon IF you have an account with MSC (we use it liberally at the shop I work at)

For us hobby guys with 9" SB lathes, the idea of taking .200" DOC is just jaw dropping. Obviously, your lathe is way way bigger and this shouldn't be even remotely shocking, but still... That was cool.

That's a neat trick for picking up the threads once you take the part out of the chuck, I usually do this type if threading operation backwards so I'm not cutting towards a hard stop, less anxiety that way.

As an offshore worker I completely understand, we use all types of lubricants and sealants to keep the saltwater out. A new piece of equipment is taken part and resembled with to ward off rust welding parts together. Teflon tape on thread as gap stop or thread sealant made for pipes on nuts and bolts, galvanized spray paint, you name it we have tried it

Use RTV on the threads to seal them from moisture and salts. Learned this working in a gold mine refinery with corrosive solutions.

Great video as always. I loved the speed at which you dropped the tool down between the inside chamfer and the outside chamfer. Smooth operator!

Makes me appreciate getting the sliding cover with my lathe. It's weird, I've been milling for quite a few years before getting a reasonable size lathe and I thought I kind of had the sharp chips thing figured out but the lathe makes a whole other world of flying razor blades.

I am always mindful of errant chips and I have the scars to prove it lol 😂

My favorite channel, you make it look easy. As a 50 year hobby machinist, I know it's not. Love the surface finish. Anchor lube is another tip I learned from you. Thanks for your videos.

hello Josh & It''s is Randy and i i like yours video is cool & Thanks Josh & Friends Randy

Always fascinating. Thank you!

Same deal in New York. I can look at a rusted exhaust stud and tell that it isn't worth wasting time with. Saw it off and drill out.....Dave

Salt is a good thing for you! Job security!

Anchor Lube needs to sponsor your channel. You've given them lots of free promotion.

Nailed it great job!

Nicely done josh we forget how good that monarch is because we see on your lion mostly 👍👍👍

It's incredible what the damage the sault does glad we don't have that problem in Australia great video.

Looks good josh

Those shavings can be like razor blades. A touch and you’re cut.

really nice.!

Thanks for showing your technique for reinserting a threaded part into the chuck.

That is a great trick to line backup thanks 😊 Keep up the good work!

wonderful tip on realigning the part back in the chuck while threading,,,,,Thanks...PB

Thanks Josh for all the tips. Especially how to reset a part for threading 👍😎👍

Thanks!

To prevent the rust of the thread, we use grease during the assembly process. That helps a lot!

This is the first time I’ve seen your video, thank you. You mentioned the northern climate, where are you from, I’m from Oklahoma that’s why I sound funny. Again thank you Sir

Been watching your videos for a while now and great inspiration to start showing some of my own ..... keep them coming, so much to learn !!

Nice job and done right the first time. Thanks for the video keep on keeping on.

I always learn something and have an enjoyable time doing it. Thanks for sharing your knowledge.

Great result . Always a good day when the part does not have to go back into the machine . 👍

That Dykem trick is genius. I’ll use that! Thanks!

marvelous Video Josh, best wishes....PB

Outstanding job Josh. That material machines nice, great finish. Looks beautiful. Thanks for sharing the process. Have a great weekend.

Very very nice work sir. A pleasure to watch.

Beautiful job Josh, and a clever method of re-indexing the thread.

You sure make the threading look easy!

Enjoyed the video, thanks. Rotating the bottle made me chuckle, but keeps it free.

Good work

Our climate is much the same. This was a cool project and it turned out great

I always learn something new. That's a nice trick to reposition a threaded nut back into the lathe chuck. Thanks for sharing. Regards Alan

Truly awesome work.

Never seen that trick for taking a threading job out of the chuck. Good stuff.

Greetings from Mayville

you do good work sir.i have some time in the machine shop. learned enough to get myself in trouble.lol never understood the threading part.enjoy your vidioes.

This channel should be called 'practical machining for getting shit done as a business' I love watching work getting done and got tired of the show and tell for youtube recliner machinists channels a few years ago. Channels like this and cutting edge engineering down under are the real deal. Putting these machines under real work loads and none of the fizzle assing around(as my old man used to say) Show the job, and get set up, and 'see how it runs'.

That was a nice job! I used to love doing jobs like that. Nothing too big though

Excellent video as usual, I’m not very confident at threading.. especially internal ones! Good to see how efficient you were with the way you made that

I live in Western New York on Lake Erie so I understand your pain lol. Rock Salt is a killer on equipment it eats through, and seizes everything up to the point where the only way to take something apart is by destructive means. Great video as always Josh, thank you for uploading! 👍👍

Nice work Mr. Topper; Great sourcing of the raw stock. Steady Hands that part is a work of art. Shame it will get an outdoor salt bath. I learned alot from this, Thanks Best kristy

Good Job. Yes the salt eats everything. That is why I lease my vehicles. I had a 2007 truck frame wrought through with only 85,000 miles. Now i turn my vehicles in and some poor sap has to deal with the wrought. Keep up the good work.

Understand completely, Detroit here. Yes, I'm very fond of my "flame" wrench, & couldn't do some projects without it.

when i showed a maintenance guy that alignment trick he wasn't buying it. when i did it he still thought i got lucky LOL

I'd have owned half the cars I've had if it wasn't for the effing salt. Anyway - I really enjoy seeing a piece of raw material pared away to show a mirror finish hidden beneath the scale - and the .200 depth of cut is amazing. I managed to do that recently and had the chips flying just like this video. They were melting my pants though so I backed off. Questions: 1. What material is the new nut made from? 2. What inserts are you running? Someone recently gave me some new Kennemetal ones that are amazing. I tend to use obsolete NOS ones because they are relatively inexpensive - but it's incredible the difference new design coatings and chip breaker features can make. 3. Do you ever do that upside down / reverse threading technique? I really like it for threading out of bores and saves me the drama of being nervous about disengaging the half nut too late. And finally.......that scribe alignment technique for getting the nut back in place after testing is brilliant. Cheers!

I have never had to deal with the salt story, we don't get snow where I live, but never the less, for certain nearly every cylinder I have taken apart presents problems with removing the top nut. I don't know what it is, maybe humidity, maybe dirt, at least I never had to cut one or torch it off. Nice work as always.

I'm in the hydraulics industry and use the exact same technique when re-chucking gland nuts.

Hello Mr Topper. I find Your videos most informative and enjoyable. As a hobby machinist I wonder 2 tings. In an earlier video You had to reduce a large diameter “slug” to a significantly smaller shaft with a flange. I understand that doing the part in this manner makes the part more resistant to stress related failure. Your work process have two disadvantages in my opinion. First the time to turn the bulk of material to chips. If You trepanned the slug and part of “outer tube” it should be a quicker process. The second disadvantage would be that the “outer tube” wold be turned into chips instead of some raw material for some oncoming project, free of charge, so to speak. At the same time You got less chips to handle. In this video I would like to knew why don’t You rewers the spindel rotation and turn Your cutter up side down. Must be a lot less stressful to start the thread in the tight inside corner and run the tread cutter out into free air? Away from the chuck. Regard’s PeO

Thats exactly the kind of nasty corrosion we get in the UK. Thanks for sharing

Great to watch, nicely explained. Good tip, I was wondering prior if you were going to remove the nut for a test fit.

Nicely done. Speaking of salt - The salt destruction in S.E. Alaska - pretty intensive. Anyway, you do excellent work. 👍👍

Lucky? Hahaha, you knew! Beautiful work."Poetry in Motion"

With all of the salt it would have to have a big impact on bridges also - thanks for sharing

Nailed It just like the way you explain the job and then do the machining of the part you describe each procedure to a T well done Cheers OH and the other chap as far as i am concerned Josh can say MY as many times as he likes in fact i don't let things like that bother me at all in don't even here it half the time as i am more interested in what he is doing very peaty of you Cheers

Your video quality is very good!!!!!!! I know that you have worked hard on different angles and fast forward. I still love how you take us step by step thru the process. I can not believe how close you get the tools to the chuck; I would surely crash. I am not a machinist but I did not know that threads could be done in multiple passes. How you get it to line up with each pass was incredible to me. To me, you are like a college professor. I can not believe that you have not been picked up on PBS; This Old Machinist. Keep up the good work. I moved to Rhinelander now; I am so glad I took the drive to meet you in person. A little blood, sweet and tears are part of the job. Thanks for the video.

I prefer using dial indicators over digital indicators as well for being able to see where I'm at in the big picture. You can watch the needle as you get near your target where the digital is flashing numbers so you end up having to respond a lot faster due to not having as much warning.

Another great tip on how to re-index a part. I was wondering how you were going to do that...removing the chuck with the part still in it seemed to be a lot of work. Fortunately you had a better idea. Thanks for all the tips you give, Josh.

Suggestion: Consider start the threading from the inside shoulder towards the tailstock. This is done by inverting the threading tool (upside down) then running the spindle CCW and thread feed towards the tail stock. This way, engagement of the threading dial/threading happened at the shoulder instead of threading to the shoulder. This stops the stress of running the tool into the shoulder and speeds up the threading process. Threading tool looks like a "top notch" zero rake insert, these benefit from being set slightly above center for internal cutting and slightly below center on external cutting. The American Machinist tradition of threading tool in-feed at 29.5 or 30 degrees is not always helpful. This is done under the belief angled in-feed helps reduce the threading tools cutting stress on the leading cutting edge. What actually happens, both threading tool edges are cutting as threading is a form cutting operation. Regardless of the in-feed direction, the leading edge of the cutting tool gets the cutting stress regardless of in-feed angle. What does and can make a difference are the A60 series "lay down" inserts with highly controlled cutting geometry. Their cutting geometry takes into account the cutting forces for threading. The angle in-feed is essentially an American machinist tradition not common else here in the world..

That road salt sure wrecks things. I saw a car on another channel in the US that had no rockers left. They only use road salt in the alpine areas in Australia and that's places I never go to. I hate the cold!

I've seen what you mean about the climate. CEE in Australia works on hydraulic cylinders and they come off intact most of the time.

I really enjoy this channel im no machinist im a design engineer having a idea on how a part could be made and what information is important to the person making the part really help with design. I can make the CAD in a lot of different way have a drawing look a lot of different way. Could you do a video looking at some of the drawing you have had to work with a what makes the good or bad drawing from your point of view.

I worked in parts for Gledhill Road Machinery. If that is a plow cylinder those weighed 70 lbs, or better. The plow would have 2 of those to pitch it right or left.AL B.

I understand the forward reverse when threading but for the life of me I just can’t wrap my mind around engage the threading gear at the SAME TIME EVERY TIME

I just learned a new way to re-index a part after threading. Thanks. Have you ever tried the method of cutting threads away from the headstock? I haven't and the only person I've seen use it is Joe P.

wow

I'm a hobby machinest at best. I find it interesting to watch a real machinist produce real world parts in real world situations.

My luck that barrell would blow a hole out the side of it the next week. LOL

I always preferred to cut internal shouldered threads on the far side of the Chuck from the back outwards, less chance of contact.

👍

Interesting video. Thanks. Do you ever use an anti seize compound when assembling those parts. I found it makes a difference in a marine environment. We sometimes used Locktite on 1/4-20 stainless threading into aluminum. It would make a seal keeping salt out and helped to separate the two dis similar metals.

Josh, That surface finish turned out phenomenal. Impressive and ya didnt even need to polish it.......What was the insert you were using? As we both know our respective DOT's dump more crap on the roads than necessary, not only salt but calcium chloride too....gets into everything not just cars n trucks.....Thanks for turning the chute on the blower.....our terrible snowstorm that was to dump up to 20 inches today, has barely spit out 1/4 inch total......so much for accurate weather forecasts.....LOL.....not complaining but if you and I were off that far in our jobs we'd be jobless...... Keep up the good work... Don

One off replacement part work, why manual machine work will always have a place in industry, because nobody sensible would bother drawing it in CAD and programming a CNC just for a single relatively simple part, though im sure you could make a few of them before the CNC got ahead. Monarch lathe is lovely, nice to see it in use over the modern Lion.

Weird as it seemed to not have a wiper seal groove cut into the gland. Great job.

pretty

Thank you for your great videos :) What material was that? 1045?

Have you ever considered getting a cordless ratchet? Seems like it'd make so many jobs like flipping those chuck teeth so much faster.

Have you ever threaded backwards or out instead of in? That way there is no possibility of crashing. Run the lathe backwards and thread on the backside with the tool cutting to the outside.

Looks like you need some riser blocks under the lathe. It seems to be low for you to use it comfortably.

Great video thanks for sharing

I dont know what material this is, but man that lathe is in good shape to produce such a spectacular finish

Great little repair job Jake, I;ve been there and done that. I'm assuming you are referring to road salt? I've had pretty good luck using anti-seize in the passed on equipment used outside but don't remember if any were road equipment such as plows or grader blades. What's been your experience with those products? I'm in Washington state and within 90 miles or so of the Canadian border. Thanks for sharing.
