    Do you need to clean the moderators that use a Tesla Valve?

    Somewhere back in time I had a tesla valve on file, I never printed. Searching for it now and can't find it. Anybody can share?

    What’s with JSB these days

    :) nice to hear from you as well. In early 80's I started my career and for a good decade I was in aluminum high pressure molds manufacturing engineering, NC and CNC programming in a next decade. So pretty much I am well aware of a low gravity casting processes and how to design/fabricate molds...

    FX Any Ideas

    In recent couple years the JSB MRD's accuracy fall apart. With my Impact MK2 I can get them group in a 1 MOA @ 50 all the way up to 70-80 1.2 MOA, but the 100 is a no go with these anymore. This based on thousands of shot tuning and testing. I see they came out with new designs, I still have...

    What’s with JSB these days

    I am lurking with the idea for couple years already to swage my own, but never got to a line to purchase - not one but couple dies. Because all the dies are clones of existing off the shelf pellets and I don't know which will work well with my 22 and 25 cal setups. The other issue is that I...

    Seeking super sharp glass

    It doesn't cost much asking for opinion. ;) He knows things ... Nobody said you need to buy from Rea. I didn't buy from him. He can turn your head in what direction to look for and it is up to your skills to locate the source and the price. I invested my time researching for prices on Brand and...

    Seeking super sharp glass

    The worst thing can happen when you ask the open forum and twenty people chime in with seventeen ideas. I was also a money making photographer in 80's and 90's, and today still have great glasses weighting a concrete block. In the past half a decade I bought more then a dozen mid to high quality...

    How do YOU challenge YOU?

    All shooting sports are mental sports. This doesn't come overnight, months of training to put all together :) "Wobbling on target"? Try to "float on target" in circular around a target. If you can float and control it CW or CCW you are on your right mind set. You don't "try" centering. The brain...

    Zan pelet sizer

    I have a .22 and .25 adjustable pellet sizer from trrob. When I received these I had to do my own fiddling to bring these to my level of liking. That is just me being very anal with things I do and how I do. I am shooting 50 and 100 BR, and I can confirm that the POI is tighter when I resize the...

    How do YOU challenge YOU?

    I have been actively competing in archery FITA and FT for over fifteen years and I learned that training and practising in real life scenarios is a must. Registering months ahead for any tournaments and I don't know what whether conditions to expect is a big risk loosing a podium because of a...

    Yong Heng piston rings

    Imagine this... :) I found these in bottom of my YH crate... Completely forgot when was that somewhere back in time I bought these. Today started a workparty, definitely I need to organize my parts inventory ... I have some many things collected just hard to remember. These happens when I buy...

    Leishy 2, with 600mm barrel/ slugs out to 100yds?

    The 100 Y/M idea is feasible, if you learn the trigger control and fine tune from there. I am shooting my .22x500 at the LR22 range silhouettes most of the time, but pellets only. For shooting rings I have found the .22 pellets work pretty well up to 80 Meters but beyond just fall apart. Can...

    Yong Heng piston rings

    A steel tube (coming out from the head) -> enters the aluminum manifold block (with a gauge). I don't know the exact size of that o-ring, I have no one to measure, I think about 5x1.8 or 5x2 ???

    Yong Heng piston rings

    Tinkering out laud now. If my memory serves me well every time I had to replace the second stage piston because of a worn rings... this green o-ring was broken. If that green o-ring is gone, the back pressure puts an extra stress on the piston "plastic" rings. I need to figure some other...

    Yong Heng piston rings

    :) Last night I ordered two piston assemblies from aliexpress, $44 USD shipping included ETA about two weeks. Today morning I was moving things around in my hobbies locker, pulled out the YH crate, and I found two BNIB piston assemblies I ordered probably last year.... I completely forgot about...

    Yong Heng piston rings

    Still subzero at my place and last night was snowing, but can't wait to start with my season. Today out of boredom I pulled out one of my tanks I think it is below 250 bars, let me refill if any actions come up soon in the backyard :) . And my YH didn't want to build up a pressure. Again ...

    FX Leopard - who is taking the plunge?

    I like the look of it as well, but I am only shooting one gun at a time 50-100 BR rings and 99% tethered. So far I could manage my impulses not to start collecting just for fun.

    Want to horde a little O-rings.

    I have a fairly large spreadsheet, I take the o-ring sizes from the airgun BOM (bill of materials) and copy paste over. Always ordering in batches of 25 or 50, sometime I duplicate the same size in NBR70 and NBR90. I think I have over 80 dimensions x25 (or 50) that is about 2K o-rings in my...
