stuart surkitt Hi Stuart, yes it’s cool aye!, I found it down the local boot fair years ago for a couple of quid, when I cleaned it up I found the war department stamp on it and it’s dated 1941 ;0) Thanks for your comment, All the best!

Yes its about the only thing that he has not damaged so far, I would like to see the results of him honing the cylinder, should cut the seals up in about thirty seconds of use.

Hi Sam, Really appreciate your fine workmanship and knowledge in the rebuild - a true craftsman!! I hooked up a desiccant canister on the low pressure intake side using a bit of surgical latex hose into a sealed canister. I used the filter fitting on the end of the hose. This keeps the moisture (most of it) out of the pump and lessens the water buildup inside the pump. The dessicant canister draws in air from the bottom, most of the canister is duck-taped from the top to within a inch of the bottom. The desiccant canister can be bought at a gun store. They’re intended for a gun safe. All you’ll see on the cigarette filter is oil. No more water. Makes sense to prevent the water from entering in the first place.

[@sambocotton5868]

Jay Kay Dee Hello Jay, I’m pleased you liked it, thank You! That’s an excellent idea, I’ve been thinking of doing something with that inlet filter, it doesn’t really look up to much! anything to keep water from getting in has got to be a good thing :0) All the best

[@albino7641]

Hello, what is the name of the nozzle that you use at the end of the diving cylinder filling station to have the air that remains in the cylinder?

[@dosso96]

Helloooo! Thank for the video, where can i buy the 2 tower for filter and condenser?? I love them!!!

[@Munky332]

Definitely room for improvement on these machines. It wouldn't be hard to adapt them to a V-twin design which might take some of the pressure off a single piston head setup, being able to spread it between "2 pistons"; also wonder why they decided to run it at full RPM, as opposed to using a reduction gear or pulley. a pulley/belt system to slow the pump down would help these things I would think (while also providing more torque). You could just take half that charcoal out of that filter and fill it half micro sieve and half charcoal, separated by a single small thin cotton element, instead of buying a whole separate tube/adding a stage.

[@garystratton4125]

From what I have seen the oil from bleed valve on cyclone separator is normal.. Granted you will get a little oil in there.because that is its purpose.

[@garystratton4125]

the run-time clock is an excellent idea...

[@sambocotton5868]

Gary Stratton Cheers Garry! I haven’t even used the Yong heng for over a year now it’s up in the loft gathering dust, I found an old 60’s made in England Siege Gorman that I managed to restore, it’s not as fast only 1 Cfm but I trust it a damned sight better than the China one🙂 All the best!

[@Glennoutdoors]

I know you love yours I have had nothing but trouble out of mine , maybe I just received a bad one .

[@sambocotton5868]

Glenn Newell I don’t remember saying I love it Glenn 😆😆😆 I’ve had some serious grief with mine, and if I hadn’t have noticed the high pressure piston was slightly hitting the head ( I machined about 15 thou off it ) it would have punched a hole in the first stage piston as well as buggering itself up, which has happened to a lot of people I believe! Every time I use it I’ve got a constant adrenaline rush wondering what oriental surprise I’m going to have to deal with next (300 bar scares the shit outta me) 😳 but having said that, as long as you don’t mind getting the spanners out, and your only even half mechanically minded, and change the oil regularly, it pumps air fast and sure beats paying someone £10 a time to fill your bottle up to only about 270 bar! Good luck, All the best!!!

[@Glennoutdoors]

Didn’t watch till the end wow what a surprise , Looks like your having all the dumb luck I’m having . It’s the little things that scares the S-t out of you .Good luck .

[@trvsmstrsn]

Sambo, Do you put anything on the threads on the high side hose connecting to the housing? Mine came with a seal in it and once I tighten it down to snug it does not pass air. From the look of your videos it looks like you do not have the seal inside

[@sambocotton5868]

Travis Masterson Hi Travis, I don’t put anything on the threads, there’s a small white nylon looking seal in the outlet block that seals the outlet hose! If it’s not passing air you’ve done it up too tight and crushed the small hole, I’ve done the same thing myself ;0) All the best!!!!!

Where did you buy your double filters? Jean Louis (France)

[@davidstorton910]

What kind of oil do you use in your Yong Heng, I heard that the one they recommend is not very good (I've got one coming from Aliexpress)

[@sambocotton5868]

David Storton Hi Dave, I’ve been using what they recommended no 46 anti-ware hydraulic oil, but like you say it’s probably not the best stuff for the job! Cheers

[@AquaTech225]

Where can I find bleed valves like at the bottom of the filters?

[@eumellopez2437]

nice vid, been following all your work,, i think you need a one way valve, on your line after the filters,,

[@sambocotton5868]

Eumel Lopez Hi Eumel, I’m pleased you liked it.Yes I agree, do you know where could I get one from ? Thanks for your comment ;0)

[@eumellopez2437]

sambo cotton i use a yoke where a one way valve is attached to the filling port,,

[@eumellopez2437]

cant post pics here for the reply option,, do you have face book?

[@sambocotton5868]

Eumel Lopez Hi Eumel, no I’m not on that I’m afraid, can you make a KZbin video of it? I’m sure other people would be very interested in it as well. I think it also needs a valve that only opens when it reaches a pressure of 3000 psi to keep the towers pressurised before they start to fill the bottle, then the filters have a much better chance to clean the air. Thank you ;0)

[@MOZELY26]

@@sambocotton5868 Hi S C great videos. I'm just getting started with the filter side of things. I think you'll find that with one way valve in line you open your part filled bottle valve/tap the one way will hold back air from tank then as soon as your compressor side builds up to equal pressure the valve will open and let air into bottle, as soon as you reach required pressure just open bleed screws on compressor and shut down as usual. The one way valve will hold air on bottle side until you close bottle valve/tap then bleed air from line and your done. By the way I was impressed with your assistants knowledge of what is being done. Cheers I look forward to some more info when you make it.

[@jiggalojonski]

Hey i seen this guy on another video where the braided line blows

[@ginginthing]

Great video. Can u give the details on how you made the double upright filter and where we can get the parts?

[@sambocotton5868]

Wino Kitty Hi wino, I didn’t make the filter towers, I got them off eBay, I made the base out of aluminium chequer plate, and since doing this video I’ve made it into a clamp to hold them tight as I don’t trust the loose threads on the end caps as their excessively loose and they would blow your head off if they ever decided to strip 😳

[@sambocotton5868]

Hi Wino, here’s a link to the filter towers! rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F263396886637 All the best!

[@ginginthing]

​@@sambocotton5868 Thx for the reply and link. Not sure about the loose thds. I might be mistaking since I can't see them, but they could be NPT/NPS pipe threads that are designed for higher loads in one direction. The o-rings help to cinch up the threads besides serving as a seal since the pipe threads are not sealed in this case like they normally are in pipe aps with pipe dope or now, teflon tape.

[@Colt3854]

Run a food colouring dye in the water to make sure it is pumping. Much easier to see if coloured.

[@sambocotton5868]

Frank Aka Vickypoint Hi Frank, yeah that’s a great idea until it’s circulated once or twice!

[@OSPREY5150]

You need a pressure maintaining valve on your air filter for it to work properly check the web for it

[@sambocotton5868]

Darren Dempsey Hi Darren, if I was filling from an empty bottle then yes I agree I would need one, but I only let my bottle go down to 3000 psi then fill it back up to 4500 psi, so the pressure’s at 3000 psi before I open the bottle valve. All the best

Never hone the inside of a small compressor cylinder. The seals will cut themselves to bits on the honed surface.

[@AquaTech225]

Not buying that

[@sidneyeaston6927]

@@AquaTech225 There is a big difference between the surface that hardened piston rings can run on and the surface that soft seals can run on not forgetting that there is no lubrication in the upper cylinder on a Yong Heng compressor. the lower cylinder is lubricated from the crank case.

[@rblomarda]

Nice clear video but your dialogue seems to be incomprehensible, just for me I guess, as me being an American English speaker from the Philippines but now living here in Switzerland. Btw, if I may suggest, if you might want to add an oil additive( Moly-Slip or equivalent, for me I've been using Per-tua for my car engine and it helps) for the lubricant. I also use Per-tua to lubricate the slide/ frame of my real guns and it really makes a difference. It will add additional slide on the racker arm and the piston too to minimize friction , thereby, reducing the heat and wear of the aforementioned. Just my honest opinion. It would also be more informative to the air gun community world, especially, those using the same type of hpa compressor if you could make more follow-up videos after several sessions on your charging throwing your personal observations and experiences. I know in one of your videos you provided the link for the out put air/oil filters and I am in such a loss which episode. So please provide them in you reply. My best regards and good luck! p.s. Try searching in KZbin regarding Per-Tua and if it's also available in your country since it is much cheaper than Moly-Slip.

Poquito M. Libugui would it cause dieseling at these extreme pressures though?
