My first example of PME. Entirely my fault and not for a normal reason! My piston head came unscrewed and actually lodged sideways as the piston was going forwards slowing it down enough for the steel rack to be ripped out. Moral of the story: use loctite

I think you’re underestimating how much a lighter piston helps pal: plastic piston head, simple bolt, nut and washer, plastic AOE spacers, Swiss-cheesed, you can get the whole piston and head down to 15g easily, even lighter with a heavy Swiss job. Your full pistons there with metal heads and metal spacers must be what... 25g+? With a light piston you can make a high speed full stroke SSG even at 350fps and avoid PME, at that level joule creep factor isn’t a major issue. Piston acceleration return is vastly different in lighter to heavy pistons.

I don’t think you’re wrong. I use to Swiss cheese pistons all the time. And then I stopped. I’ve not really had a problem since. I will Swiss cheese pistons rarely in the case that I’m building an SSG to shoot over 40RPS. But, I’d prefer to keep my piston whole, correct AOE between the piston and piston head, use a heavier spring, short stroke and get better trigger response, less over spin and high ROF. I really think there’s a lot of preference involved in avoiding PME.

I am curious if this is occurring in my build rn. I am running a shs 13.1s with a ZCI 16 TPA motor and M120 spring getting a max of 30 rps. On semi my FPS is consistently at 340-345, but on full auto my gun has a drop of like 50 to 60 FPS according to my lighter BT chrono/tracer. Do you think this is my problem? I was thinking this could be the case?
@happyrobot6396

Logan Walker no, definitely not. If you were getting PME on auto, your piston or sector teeth would’ve already taken heavy damage. This is most likely an air nozzle-hopup meshing issue. For starters I would cut a couple coils off your tappet return spring. Very unlikely that your tappet is too slow, but ya never know. Also with an m120 and 30rps, you’re not getting close to PME zone, forgot to add that
@gleaks7922
4 жыл бұрын
It's not pme, it's either a tappet return issue as happyrobot mentioned or it's because when your piston hits the cylinder head the impact transfers to the hop chamber shifting it forward and breaking the seal. Try spacing the hop chamber with orings around the barrel that way it doesn't move when you fire full auto.

Using washers to correct AOE is a surefire way to snap the piston head right off the piston. Use sorbo pads glued too the back of the cylinder head. You can buy them premade or make them out of shoe souls. My favorite thing to make them out of however is the high density foam that holds the motors in their cases

@@TheAirsoftTech im just giving you tips, tech to tech. Just because its never happened to you doesnt mean it doesnt happen. Unless youre using washers with the same ID as the piston head screw, you run the risk of one moving and scratching the inside of the cylinder. The only upside i can see to correcting AOE with washer would be that you dont lose any air volume. But that can be corrected with a stronger spring or different cylinder all together. Idk man like i said im just giving tips... just like you. Theres a reason the piston head get press fit into the piston. Extending an m3 screw with washers on something that sees extreme force its whole life is a recipe for disaster and thats another thing too use washers you need to replace the original piston head screw with a longer one. Correcting AOE from the cylinder head allows the piston head to be pressed into the piston as intended and you dont need to go looking for the correct length screw to replace. Ive done the washer thing twice and both times snapped the screw. Build your builds how you want like i said im just giving tips just like you. I personally would just rather build my builds to have zero "what ifs" so they last as long as possible.
