Stai cia kaip daryti odini manzeta.
Vietoj plastmasines apravkes naudojau paciu sautuvo korpusa, sumirkyta oda priverziau prie stumoklio vietoj buvusiu manzeto ir ikisau i sautovo korpusa atvirksciau kad tik ilistu i vidu ir parsisleptu oda (lygiai su korpuso galu), toliau buvo dziovinama ant radiatoriaus per nakti ir veliau istarukus mirkyta tepale ir dedama viskas pagal tvarka atgal.
Vietiniams galesiu duoti odos , nes turiu tikrai vertos demesio.
Some scrap leather, soaked in water overnight. A piece of MDF board with a 1 1/8" hole drilled in it, and a socket. The leather is about 1/8 inch thick
I rubbed the MDF board with silicone oil, then pounded the socket down ino the leather til I got about 1/4 inch depth, then cut off the excess with the razor saw.
Let the whole thing dry overnight, or if you're in a hurry, bake it in the oven at 250 for an hour or so.
Sorry for the crappy pics, my digital doesn't like close-ups.
The leather is about 1/8 inch thick. From what I've learned about leather pump cups, they're theoretically supposed to be full grain, with the smooth side out.
But I just bought a bag of leather scraps at the local craft store, and used the thickest piece in the bag, which was a split, meaning it has suede on both sides.
The great thing about leather seals is that they conform, and "shoot in." I put one of these home-made jobs in the refurbished Wischo, and it actually dieseled for the first 50 or so rounds, so I know I'm getting good compression. It later settled down to nice shots with a light haze left in the barrel, a sign of GOOD combustion in a leather seal gun.
Not such good luck with the Lucznik (oops, unintentional pun.) I'm pretty sure you have to have just the right size and stiffness of filler inside the cup. I was able to reuse the original mystery orange washers on the Wischo, but in the Lucznik, I used a plastic plumbing washer, and I think I'm getting some blow-by, or I could still have breach seal issues. Regardless, the velocity seems low, and there's no indication of combustion, despite a good dose of silicone oil on the seal prior to reassembly.
If one were so equipped, one could drill a more precisely sized hole in the mold (piece of wood) then find the tightest socket to fit. Myself, I was limited to 1", 1 1/8", and 1 1/4" hole saws. 1 1/8" seemed the best compromise.
