I’m really interested in buying your slugs, are you still manufacturing them?

You can speed the end performance a bit with feeding it slightly higher pressure feed air. The geometry of the compression is basicly limited to slightly over 300 bar. In the end it just compresses the air in the pistons and lets it expand again without moving any air forward. That is just the compression ratio of the pistons. Which is A LOT for a 2 stage pump. At our fire station the pump is 5 stages for the same pressure. But it probably costs 50 times the money. Don't overdo it! I guess it will stall quickly. But even with 1.1 bar at the input, you probably increase the feed rate at max pressure by relevant factor. An interstage cooler would also work and do the same.

I got 3 running hours out of my last Yong Heng. I have had 4 or 5 of them. Not going back. Looking hard at the GX CS4.

This is the video i was looking for, pretty much everyone else is only shooting pellets with this gun and im really interested in the slug performance

When you say you “slugged the barrel “ what do you mean?😊😊

Pretty sure none of these are going to corrode because they’re all made of anodized aluminum I use both of those you have there. The new one you got is my stage 1, and then the second one with the desiccant as my second stage. Super clean and dry.

Where is the air input?

Nice job. I will refinish my 1938 Mossberg 44 stock and re-blue the barrel. Thank you.

Very informative video, thank you.

But how would you do the brass screw part on a 58 cal barrel

Appears you like the Katran B 25 cal. Thinking about getting one

Is there any place that sells the "o" ring for the check valve of YongHeng without buying the whole kit ?

Where can i buy the pcp conversion? Id like to keep mine pistol size,or alittle bigger...thanks

Great video and info...will be ordering bunch avs slugs for my Vulcans

Normally, the type of isolator you are using would be used to protect a nice hardwood floor or table, not to protect the pump from vibrations. A mount to protect the pump itself would be a very heavy frame bolted solidly to the floor or weighted pallet to prevent the components from making large vibration excursions.

Reminds me of roping trees in my younger days 😂 thx for the idea bud

The most informative and easy to understand video I have ever watched; I am going to finish and exhibition grade black walnut stock

Hey my high compression piston seems to be going to high and locking up because it cannot return the stroke. I'm fairly used to piston strokes from racing motorcycles, 2 strokes, but this thing has ne really confused and hard to find good customer support. I'm getting ready to replace the whole unit or just whole top end but I'm really interested in figuring this out. Also, the top high compression piston is tight! Any input would be appreciated

Just getting into paint ball, this is exactly what I needed. Thank you, Cheers 🍻

I’m so jealous of the Scott Allen anti-vibration device. I keep thinking about it day after day month after month trying to figure out how to make my own. I know ridiculous haha

How to run compressor more than2 minutes My compressor is auto shutdown top model and it reaches 75 degree in just 2 minutes and shuts itself down.! My room temperature is 35 degrees and i use room temperature water Is this normal to shut this much fast in new Compressor ?

What did you wet the stock with to raise the grain? Water? Tru Oil? Mineral Spirits? Thanks!

Muchas gracias ..!!

I closed my tank and then bleed the system!!!

Shame we can't get avs in the uk, Does kelly sell them, I bought a mag and barrel from kelly.

Did you try .254 flat ?

@18:47, Why did those Huban Gun Engineers not think to add a Trigger lock tethered to that rotating cylinder lever? Why didn't they just make that whole cylinder like a revolver where it rolls out the side and then you roll it back in.

my yong heng pump has been sitting inside unused for several months and just randomly started leaking oil. quite a bit, actually. any tips for what i should inspect?

I am Interested in the anti vibration device

This is by far a better video than I thought it would be at the beginning. not many people going into this kind of detail. I really appreciate it.

Did your friend decide to start selling the stabling stand for the Yong Heng? If so what is the price, and how do I contact him?

200 buy one

Question? When you said "I slugged my gun.?" Do you mean you just tuned the fps or did you do something to the barrel?

Awesome review!

The table looks good but the plywood going across grain just looks wrong.

More commercials than cable tv

You haven't posted any videos for some time, hope everything is fine.

Cool, thank you for the effort.

I think I have one of the same tanks from Phoenix Fire Department that was unused 7-8 years ago. I was filling it with my Shoebox compressor and high pressure filters were just kinda getting started. I quit filling my tank due to moisture concerns about 6-8 months after I got it. I'm sure mine has corrosion in the aluminum inside. Mines been sitting at 3000 PSI for years now. They say these tanks really are good for 30 years as long as their not damaged and beat up, but the corrosion I'm sure that's in mine also worries me way more than the date. After seeing yours inside I think mine will be retired also. I have a GX CS4 coming and will just fill my PCP's directly. Those filters are kinda scary too with 4500 PSI on them so i never bought one.

Don't leave us hanging. Did you ever get around to making a video of your Gauntlet 2 25, after sending it to be worked on? Interested to see what the upgrades did on accuracy. Am on the fence about getting it in 25 or 30SL. I love all the information from your videos. Thanks

Why the mix of oil and mineral spirit ls, is it to tin oit enough to soak deep in wood?

Good video, except turn the TV off

Kelly at KRAZ Cool AG is the BEST!!! I use your .253 46 grain in .25 & .2193 34 grain in .22 dish slugs & nothings safe out to 150 yards! Your quality control is amazing... I've order over 1500 slugs in each size and have never had to re-tune either rifle. Thx :)

Wish just one of these videos was done with a checkered stock. I’d like to understand how to apply the multiple coats with the checkering.

My check valve shredded too. I replaced it with a billet on made from stainless. Worked great! I also opened up the piston arm and pressed a bearing in there an turned the crank down to fit the new bearing. Worked fabulous and ran alot less hot too

"4 in one hole." "Yea, I loosened my grip." Just like shooting a break barrel correctly, (but not as touchy),--get the forces off the gun and let it do it's thing. That includes cheek and shoulder,---just barely touch.

Is this better than the AEA SF standard?

I have a question would I be able to connect this tank on the Hatsan NeutronStar? Cuz I plan to bump up the power too and I want a good amount of shots at the most power I can get?

If you're getting "carbon buildup" something is wrong. This isn't an engine, nothing is supposed to be burning in there. You are probably using the wrong oil, which is detonating during compression in the high pressure stage.

I know this is a very old video, but do you still answer questions here in the comments? If you do...... after the last wet sanding with 1000 grit, and the last very light coat of Tru-Oil, do you buff it with the steel wool again or just leave it as is? I hope you answer these still. Great video. I think this is going to work out great on my Daisy CMP 853 air rifle.
