I think,........
I will have to surprize you guys with pictures when it's done. Santa came early, now I'm just waiting for the truck with the wood to arrive....curious?
Oh yea, and I built that pumper for myself too, shot 530FPS at 10 pumps in .22 with cheapo Daisy wadcutters over the chrony today. Pumped it to 20 pumps just to see, and only managed 590...think there's more tweaking to do, or I need a barrel longer than 14".....Nothing left in the valve when I was done, loud as heck, glad I didn't put a debouncer in there, woulda ruined the "CRACK!". Wood looks pretty nice too. I like it, but I think we will part ways once it's totally "worked out".
