Here's mine:Was doing R&Rs with brute force. Mine! Worked well enuf for the RWS/Diana 48/54/56 power AGs but the Hatsan super magnums made for one heck of a workout! So what you see above is what I came up with. Based on a Rick Eutsler design. The open ended ratcheting wrench needs to be replaced with a socket & ratcheting handle. And the small piece of wood used for the action end plug could be improved on but it works well enuf for me. I did have to reinforce the rightmost section of sch40 PVC pipe after discovering it bent in the opposite direction when used on the Hatsan super magnums. Not an issue with the RWS/Diana 48/54/56 upgraded to Vortek or JM/ARH kits. So I bought a very large diameter steel bolt & cut off its head & then plastic epoxied it within the pipe. Seems to have done the trick.
