Well, I have had the .22 synrod and benji pump now for a couple months. Everything is great except for pumping. Last weekend I boosted the pump and it still is a pain ( even though boosting cut the pumps in half). Pumping just kind of ruins the fun sometimes. Planning on motorizing the pump like the videos on youtube. I seen only one for sale from Co2 airguns. $998.00 are you kidding?So it looks like the biggest cost will be the motor assembly for me. I just want to get the motor and gear box right on paper first before buying one. So, if anyone knows about the Lbs per inch ratings on DC right angle drive motors, I can use some help.It looks like 1300 lbs/in is needed for the task.Meaning, 8.5 inch radius and 150 lbs push pull torque/power. I was looking at a 1/4 horse DC right angle drive motor with a 100:1 gear box. I just don't know if that would do it ? any thoughts ?Gathering up the steel this week to work on the frame over the weekend.
Well I'm 67 and using the hand pump before I can shoot cuts into my play and as an aside for an old fart not in bad shape either just lazy
a searching for pump boosting from the Gateway "menu page" (other forums call it the forum menu or forum listing) will get you all you want to know...basically you use an 80psi OIL LESS compressor regulated down to 20psi to feed the pump...the real question is how power are you playing with?...at the range shooting an average of 2 shots a minute...a 15fpe .177 pumping is a viable option 1/2 hour of pumping gets you an hour of shooting..my .25 BT65 at 55fpe other the other hand makes hand pumping a joke, pump for an hour to shoot for 15 minutes..and there are the "Range Clowns" that laugh and ask how your bicycle is doing while they shoot store bought PB ammo....which is where the big .25s and it's bigger and badder cousins come into play, when you shoot better groups at 100 yard than the PB guys with the big mouths...
