Hey. A friend of mine asked me what i am doing at work and i showed her this video. Thanks for the video it helped me to explain my daily work. Greatings from hörbiger vienna.
Gary, found your site a month ago, love it and the QUALITY work you put out. Not many people anymore put in the effort and workmanship that you do, I'm very impressed! Very much like the restorations that you do.
Gary, thanks for the video. A great Sunday with new videos from you, Oxtool, and Stefan Gotteswinter. I've had zero experience with machine shop, but I'm learning and appreciating a lot from you. I'm what you might call a retired hairy legged nail bender. Thanks for the content, nice to soak up something new. Cheers
Thank you Brian! Coming from you that means a lot. Always nice to have you stop by and check out my videos. I have been watching your videos for a very long time. I need to do a better job at leaving comments. But you always get a thumbs up from me :) Gary
Hi Gary, Like others have said, I appreciate your attention to detail. I'm working my way through your entire video library and this is the first comment I have left. Keep them coming! And the longer the better for me...
Hi Gary, worked in an oil refinery some 25 years ago where we had 11kv electric motor driven hydrogen compressors made in the Netherlands. Fitter inadvertendly installed discharge valve the wrong way, they ran it up and heard knocking sound, the ensuing explosion could be heard some 30 miles away with most windows blown in the refinery. The cylinder head was embedded in the standby machine. Luckily the men only suffered ruptured ear drums. A worldwide recall was performed by the manufacturer and valves were modified so they could only installed one way. Just goes to show a simple mistake can have disastrous consequences.
Your neat little chuck-key rack on your LeBlond finally embarrassed me enough to find a solution to my chuck-key problem for my most commonly used chuck ...... finally got tired of picking it up out of the chips and oil -- or off the floor ! Also, Jean-Paul commented earlier about your techniques for sharpening your inserts . I too sharpen mine, but I would also like see your methods and setups for the way that you do it . I realize that my ways are neither the best or the worse ways of doing it and never too old to learn .
@@OldIronMachineWorks I had no sooner sent that when got into some old Ampco22 aluminum bronze stock to turn and found that my inserts, that had been cutting mild steel and aluminum satisfactorily would not touch the Ampco, at all ! ... just loaded down the lathe . A quick dressing of my inserts with the diamond wheel and the Ampco cut like butter . Such is the nature of that material . Probably why it makes such good bushings -- if it doesn't cut, it work hardens and lasts forever . Drilling and tapping presents the same problem -- if the tooling isn't SHARP ...... it ain't gonna go ! If I remember right, some of the nickel/chrome alloys present the same problem .
G’day Gary. A very interesting video mate. Should be titled, “Valves, a definitive guide”. You really know your stuff buddy. Thanks for sharing. Oh, I’ve lost your email address. I think I can remember it so I’ll try. Cheers 🍻. Aaron
That was really interesting Gary, I serviced carbon/tungsten mechanical rotary seals for several years, getting liquids to seal can be a challenge depending on the product but metal on metal with high pressure gasses now that's a challenge, great content. Tell us, what are the components made from, the large ring seat you were turning for the first valve you worked on looked like a high nickle content stainless judging by the way it cut.
Hey Gary great video . I wish i would have got to work on the stuff you worked on . As for the sand blaster how is it pressure fed can you show some photos. Thanks for the videos .
On a future video, could you elaborate further on how you resharpen carbide inserts until there's nothing left? I've played around with diamond lapping with mixed results. Do you mind covering your technique? Any special tips? I'm sure that many hobby machinists would love to know how to save money on carbide. Thanks much, a great informative video as always
I Guarantee its nothing fancy, I was going to show more in this video but edited out because the video was already way longer than I wanted. I will keep it in mind. Thanks for checking out the video. Gary
Fascinating, how do those valves work? Do the plates rotate to cover and uncover the holes? I'm pretty ignorant about such things, and they fascinate me. I was also wondering about lapping. Is it a kind of process similar to surface grinding? I assume the objective is flatness and smoothness. Love the "special sauce", looks disgusting! And I must confess that for me, the best parts of your videos are the shots at the beginning and end of the Rio Vista Bridge. Thanks Gary. Your contributions always make my day.
Alan, the valve plates ( the thin round plates ) do not rotate, they just lift straight off of the valve seat to let the gas pass throw and then back down to reseal. To simplify things the lapping table is a flat surface with a gritty substance on it. When you put a part on it to lap it only removes the high spots until its lapped flat. Hope that helps.
I had no idea there were valves that worked like that. I wonder how they calibrate them. And what sort of tolerance is allowed. And what that company is gonna do when Gary retires! Great vids!
I always like to see professional repair work as it fits in with "make do and mend" philosophy. I am curios that you dont use a surface grinder in your repairs, is it not suitable or not in your shop.
@@OldIronMachineWorks i guessed that was the case, but better to what you can with what you've got than do nothing because there is a better machine that you haven't got.
Robert, I do not believe any part of them are made in China. That large Valve new would cost upwards of 10K If China did make them I would think it would cost less. But I really don't know for sure.

Excellent demonstration of valveplate repair. I was womdering if you had ever done the same kind of work on 5 ton or larger recipercating refrigerant compressor valve plates? Always a pleasure to see your careful work.Thanks.
You should show more. it's interesting. I have never seen those kind of valves apart.
Hey. A friend of mine asked me what i am doing at work and i showed her this video. Thanks for the video it helped me to explain my daily work.

Very interesting Gary, great job.
Thank you sir.
Something odd ball comes in the shop. Boss man says "Give it to Gary to fix." :)
Tom, you definitely got that right :)
Far from boring as your video production and discussion are on par with your excellent craftsmanship
My friend, you are WAY to kind. Thank you

Hello Gary,
A good video... interesting to see the various valves... did you guys make the lapping table or was it purchased...
Take care.
Paul,,
Paul, its shop made. They bought it from a company that went out of business over 25 years ago. Thanks for stopping by. Gary
Gary, you sure have some skills. Top-Notch stuff shown. Very interesting. Never seen such a lapping machine before.
Thank you, I appreciate the kind words
Great video 👍👍
Thank you very much Sir. I really appreciate the kind word. Gary
I love these genral repair subjects thanks
Thank you Gary, Gary :)
I thought you were going to lap on a granite table or another flat surface by hand. Very cool to see the lapping machine. Awesome work : )
Great video Gary, keep em coming buddy
"Still looks big in the picture" (same picture) 🤷♂️😆
Thank you Ralfy. But I don't think I will be able to keep up with you as far as putting out videos. Thank for stopping by.
@@OldIronMachineWorks lots of love to you buddy

Holly crap, A lot of our stuff have safety relief valves that help in that area.
Always informative, your videos Gary. Nice work
Thanks Randy
top notch work again gary i like seeing all your different repairs
Thanks Clarence
Really enjoyed the valve work. More would be great.
Thanks Richard.
That was powerful lot of valves. Thanks for the video.
Thanks Harold
Interesting for me.
I did not see lapping table/machine in other videos.
Thank you for the content
Thanks Dale
@@OldIronMachineWorks I enjoy your content and explaining failures and function
I get involved in lots of odd ball machinist work

Reminds me of my days rebuilding valves for V Major Air Compressors. 16 valves for a V Twin, ranging in size from 500 cfm to 3000cfm.
Nothing boring about valves :)
Excellent work That was a very good video
Thanks Frank

Thanks for the video Gary. Reminds me of changing out those valves when I worked at the evil polluting chemical plant. 😉😁
LOL Harold, Thanks for watching. The big valves are really fun to change when there over 200 degrees.
This was definitely interesting to me. Thumbs up
Thanks Andy
Hey Gary great video . I wish i would have got to work on the stuff you worked on . As for the sand blaster how is it pressure fed can you show some photos. Thanks for the videos .
Very interesting, Gary. Thanks for sharing. I like this kind of stuff.
Thanks Joe, nice seeing you on ARW Sunday. Sounds like the fires got a little to close for comfort. Thanks for stopping by. Gary
lol.. you do work on everything... thanks Gary .

Glenn, most valves I am now rebuilding in my home shop.
I learned a lot from this. Thanks 👍
Really, really cool. Thank you.
Thanks Paul
Interesting work mate, where they chevy heads at the start?
Robbie, yes a couple small block heads. Thanks for stopping by. Gary
Great stuff!

Thanks Chris. I wish I had a big surface grinder at work. I would be using it all the time. But I just use what I have. Thanks for stopping by. Gary
@@OldIronMachineWorks i guessed that was the case, but better to what you can with what you've got than do nothing because there is a better machine that you haven't got.
I learn something from every video. I can send you a pile of air compressors if you need something work on.
Trust me, I have plenty to work on already :) Thanks for checking out the video. Gary
how are you checking if they are still leaking or not.
Send it to us at Hoerbiger Baton Rouge...
I learned a lot
Are the hoerbiger valves you refurbish made in china or are they older and made elsewhere? Are the kits you get chinese?
Robert, I do not believe any part of them are made in China. That large Valve new would cost upwards of 10K If China did make them I would think it would cost less. But I really don't know for sure.
How much flow restriction do the valves impose?
That depends on the application. But the valves should flow whatever the compressors are capable of pumping.
How do i contact you ?
👍🏻👍🏻
Thanks Craig
