Ok ,got your attention now. MENTION SLR , eyes raise up..
So those who know ,know that ..
1. Theoben seals are like a fine women. … great when they are working ,but extremely hard to find
2. They tend to be soft and burn easily ( Probably from over psi for extra cowboy ft lbs)
3. One man has them and has a monoply on them and will not sell them UNLESS you send the gun to him .. oh yeah. THEY ARE let’s say $$$$
4. AAAND , finely a poor design in my opinion. A soft cast seal that depends on a shoulder button inserted into the piston itself. I’m SORRY THEOBEN GUYS.. THERE ARE BETTER DESIGNS. Simple HW HEAD THAT TAKES A UNIVERSAL SEAL.
. ITS ,OK, Air Arms dropped the ball to,on their Pro Elite to. ( I’m firing lasers today
)
5. The Zepher or however it’s spelled. (Got to watch out for Karl now ) , DOES NOTHING for power . Nothing a standard cup seal wouldn’t do. Flame
…. I hear it now,, ” it’s for heat transfer”. …… “ it channels the magic air” ….. “it gives softer recoil”…..
If you believe that ,”I have some ocean front property in Arizona ”. GS . I’ll sell ya.
SO , I’m testing a design I saw on a UK form that uses a 27.5 mm seal. ( fits the SLR AS IM SURE OTHERS WELL, EXCLUDING ELIMINATORS)
It’s a delrin plug with a tapped center with 4 legs that spread and grap the interior ledge on the piston.
This is a 12 ft lb gun, with light weight cocking and short stroke. Heats not a big issue . ( unless the power cowboys get their hands on a pump)
I am sure a O-Ring design would work well to. I’m not saying that if you have a factory gun this is a better Idea. It’s a work around without modifying anything on the gun,so as you can go back to 100% original if you want or find a factory seal.
For the record, If I owned this gun ,I would be shooting it weekly. I don’t watch them collect dust.. A TOOL unused is USELESS.
Am I planning on making them for sale. Nope. It was a work around until or ,IF ,THE OWNER WANTS TO GO BACK.
Just for you Theoben fans. I will do a post on the re build when complete. I’m doing full stock refinish and re- blue.
