Title: using a mountain bike front fork suspension pump to pressurize a vortex piston
Post by: D14Jeff on October 23, 2014, 11:53:48 PM
found a video of a guy doing it .....

these pumps start around $40ish bucks , about $150ish lower than a PCP pump making its much easier financially to adjust the pressure in hatsans gas rams .

don't know what he pumped it up to , but it easily shot through 18mm plywood . thought others here might find this interesting .........

Is there any info out there about how he made that rear tail plug?

Did you notice that he wasn't wearing any shoes when he shot through the board? A pellet fragment or a splinter of that wood could have very easily added a little excitement to his video.
