    Got it! Thanks!

    Hmmmm, So the aluminum shroud moderates better than the carbon fiber version. Interesting! Woulda thought just the opposite.

    Is the tensioner the shroud?

    Thanks for the replies! I will prolly use first on my Avenger. Longer barrel…….but it is also shooting pretty well now.

    BTW, what is the carbon tensioner? Have not heard of this before……

    Over three different sessions I have shot 5-6 shot groups and adjusted between each group.  The first two sessions were gross adjustments, turning the dial 1/8th of a rotation each time at major sub-tensions.  Those two sessions showed a repeating pattern of tightening and loosening groups.  I chose the first major shrinkage as my focal point, as it is closest to the fully extended length and therefore easier to re-set at the base line "zero".

    Today I started examined the prior targets, and determined that between 6 and 7 major ticks from zero was the first best area to examine.  I shot groups from 5.0 to 8.0 turns and then shot from 8.0.to 5.0 turns, making a minor tick adjustment between each group.  There was some wind, even so, there was a repeating and noticable trend in the group size.  I will repeat the test again on a different day to normalize the data.    Note, I am not a super shooter and I make no claims to be otherwise.

    Does the threaded weighted adjuster make a difference in how MY gun shoots??  Yep, it sure does.  Does it magically make all my pellets go perfectly where I want them?? Of course not!

    I expect the tuner will eventually help my tune to reach a plateau, where most errors can then be traced to the fool on the trigger rather than the tool in his hands.  Take out one variable at a time.

    With my FX Maverick .22 Compact, I have "discovered" exactly who the fool on the trigger is…………..Not many excuses are valid if you miss with the right tune.

    Thanks for the replies! I am thinking I am just pushing/wasting too much air thru the system, too, with the lighter pellets. I was hoping to be able to use all three ammos(15.89, 18.13 and 22 gr hybrids) with just fiddling with the hammer spring but……

    Thanks folks! Really appreciate the help! I never noticed it on the magazine before………glue works and a little silicone oil after.

    Thanks again!!

    Thanks Patrick1. However, it’s kind of a challenge to find a dry air conditioned room out at range 😉

    Ahhhh…….that IS a problem!!

    That is a HUUUGE amount of werq you did there Steve!  People with Mavericks are really going to appreciate this for sure.  I think they all owe you a big fat Kiss.  On the forehead not the mouth though.  ;^)

    Amen to this! I have a new .22 compact and this will help me enormously! Thanks, Steve!

    Hey guys,

    So I received my "Spritech" orange compressor 2 weeks ago off Amazon and used it for the first time yesterday at the range, twice with no issues :) I have a 2 questions about this compressor if anyone can share from personal experience:

    1. A gentleman at the range stated that when filling his gun with his YongHeng, in order to extend his compressor's "life", once the gun is full, he usually bleeds the air while the compressor is STILL running – then he shuts the compressor off. By doing so, he's making the "turn-off stage" easier on the piston of compressor (instead of hitting the "compressor" button which will turn it off and then bleeding out the air). He compared this to driving a car say, 80mph, and then soddenly turning off the engine at once rather than hitting the breaks, slowing down, coming to a full stop then turning off the engine. It does make since to me, just wondering if anyone has ever tried that with this or with a different  comparable compressor?

    2. Also, since this is an oil-less/waterless compressor and regardless of the manual, what is the max temperature which you'd turn off this compressor at to prevent early failure in C or F?   (I will use silicon oil moving forward, just curious about a recommended max temp for this type of compressors in your opinion:)

    Thanks a lot to anyone able to share!

    I have a version of this from R&L Airguns. It works. Answer to #2 is simple…….keep as cool as possible, to the extreme…….. in air conditioned, dry room.

    I don't see any problem with using a very small amount of coolant, I just wouldn't add very much. Between a little coolant and Red Line water wetter, it will help prevent algae from forming in the cooling bucket as well as limit corrosion of the aluminum parts. ( for those who don't change the water each time)

    As a side note, I started out using the full synthetic Husky compressor oil in my YH when it was new, but after experiencing detonation and a broken 2nd stage piston, I moved to a better oil. Yall do as you like, no Royal Purple or Huskey for me, and I no longer get the crackling sound I used to get when I used the Huskey. YMMV.

     

    So, you got ignition(dieseling) from the Synthetic compressor oil? Some of it must have seeped by the rings to the high pressure chamber. Maybe some "lighter ends" in the synthetic? Wow! But……wouldn't the 46 oil cause the same issue? What kind of higher quality oil did you end up using, if I might ask?

    Where can you actually get a drawing and buy internal parts for these air cooled compressors? I have been interested in the versions that have the DC power supply built in, but without a reliable source of parts, and documentation it's a throw away device. 

    If you find them, kindly let me know!

    Found this Chinese unbranded PCP air compressor sold online at several places.   Are these sold under any brand name?  What is the reliability, etc? 

    -air-cooled, no oil 

    -0.6L or less

    – 30 mins max. run time

     

    Please see my post on this type compressor I got from R&L Airguns. I may have screwed something up in operation of it but parts, except o-ring, blast seals, etc. are hard to find, IMO.

    Your best option is soft water but not distilled as the purity of distilled can cause erosion, soft water is free of the calcium and magnesium that causes scale to form, but not so pure as to cause erosion of the cooling jacket and fittings.

    Why not use "antifreeze" with additives to prevent corrosion? Most cars have aluminum blocks cuz they are lighter and aluminum transmits heat (out), better than cast iron.

    Just curious…..

    Here is a group of photos of my compressor. There is a small hole at the top of the cylinder that is pictured. Can anyone advise if there is supposed to be a screw/spring/valve in there.

    If so, it is, obviously, missing……..so where can I get these parts? Please help……I can't shoot!!

    BTW, If I get the Yong Heng, I want to upgrade on delivery of dry air, now that I better understand the downside of NOT having the dry air. My current use of the R&L unit is not excessive, I don't believe, as I shoot only a few times per week. I am re-reading some other posts on this site to see if I missed something like not using the auto stop, which puts a lot of unnecessary stress on the compressor….so release air before turning off the motor.

    I think there is confusion on the compressor you currently have. It’s technically not a shoebox compressor. There used to be a company that made the actual Shoebox compressor, it had Shoebox written on the case it was in. This compressor wasn’t anything like the one you have. You connected it to a standard compressor that would pump to 120 – 150 psi and it boosted the air pressure to around 4500 psi. You have an electric compressor that works on it’s own without an additional compressor needed. I haven’t had one like you currently have and the reviews seem very mixed on them. I feel a Yong Heng is one of the best budget compressors you can buy if you are not wanting to spend the additional money for a Coltri or an Alkin. They are easy to work on and parts are readily available and not expensive. The one I have is about a year old and still works fine. If you can spend the money for an Coltri or Alkin you shouldn’t have any problems and the compressor will last for many years.

    Yeah! My mistake there. Thought all the small, non water cooled ones were called shoebox. I'm new to the PCP stuff and not yet ready to spend $2-3000 for the high end compressors as I am learning, or re-learning about the equipment. Sounds like the Yong Heng is the way to go for me, right now……..if I can find a real Yong Heng with all of the original features, esp the 2nd water drain on the left side of the compressor. Or is this asking too much?
