Got my hands on some goodies today! a few Salvimar race kits and vacuum muzzles...
It's not exactly new, but the new race kits from 2018 onwards I believe now come with turned Delrin pistons as opposed to casting. You can feel and see the turning marks on the piston and they appear to be more substantial/higher quality. Due to it being milled out of Delrin the plastic should have a grain structure as appose to casting which has none. I believe Salvimar are the first guys commercially to release a turned Delrin piston, with everyone else being cast with the exception of some exotics...
Salvimar also claims the O rings to be Teflon coated which polishes and cleans the inner tube during its operation. They stood up very well to the torture tests and I'm convinced these are the new best plastic pistons available. I've cracked/ totally destroyed a number of salvimar pistons during torture testing, see below...
Ouch...
The vacuum muzzles as mentioned in an earlier post are essentially the same apart from the detachable front muzzle piece. They are substantially longer and I believe the reason salvimar did this is so when the shaft enters/ exits the shaft, it is at a shallower angle so the shaft tang cannot blow out the aluminum ring where the cuff holds onto.
this is one of the fatal flaws of the design - they are too thin and I've seen a number of broken ones, and I've totally butchered 2 of them after modifying them for 10mm spears and the slightest bit of recoil in the vertical and horizontal planes totally broke it.. once they break the vacuum muzzle fails to seal by itself...
So - good to see them always improving and changing their products for what appears to be the better!
Also, meet a little apple. Little apple preys on fish in caves and is very good at doing so!
