Who's buying the new Umarex Primal 20 gauge shotgun? Being able to get a whole ounce and more of shot in there and with that huge air cylinder, it looks like it will be good for turkeys and geese, plus get 4 good shots per fill minimum. I'm going to buy it and give it a go as another tinkering...

My Yong Heng compressor connecting rod's pointed oil "dipping tip" that splash feeds oil around inside of the crankcase to the rod ends and cylinder walls broke off sometime recently. (Probably from harmonic vibration.) This breakage resulted in little to no oil being slung around the...
