So a few weeks ago i decided it was time to get back into the game and after doing some research was glad to see Gen 8’s were still super viable, so rather then trying to learn something new i thought the best place would be to start with a gen8 and work my way up.
In all honesty i didnt really test the blaster, so figuring out if its manufacture fault or user error is almost impossible.
I run 2-3 mags through it after purchase then tore it down and installed an oversized O-ring, and 1.3 spring, and chucked a fully charged 11.1v into it. after running a few mags through it I noticed a grinding sound after firing and realised the anti reverse latch had come loose, I fixed that up and the next day went to a local game, i played for a solid 3-4 hours and felt like it was under-performing however wasnt using a hop up so assumed that was the issue. Bought a hop up and was getting fairly tight spread at 15 m and was somewhat happy with its performance.
A week later i took it into a local retailer and asked them to chrono it for me, only to find out it was only doing about 180-190, i asked the guy what he thought and was told to put in an alloy barrel and seal it as much as a could, we also replaced the return spring as the one i was using already had some rust and was coated in smashed gels, we tested it again and it was at about 240-250, which is what a stock V8 runs at, which still didnt make sense because it had a 1.3 and good seal in the cylinder. It was at this point when comparing it to the stores demo V8 that i noticed it still had a grinding noise, mind you using nylon gears, and the demo one was sounding much more slapier and cleaner with a clean thud at each trigger pull, where as mine had this winding down noise after each shot. I left the store confused and went and bought some silicon lube so i could pull it down when i got home and just check everything like gears and what not. After not finding any issues as in no wear on gears or stripping or any noticeable snags in the gear movement i re-greased and put back together, now is probably a good time to mention i accidentally run the gearbox without the spring in it by accident just as a slip of the mind when rebuilding, it was only 1 or 2 trigger pulls and didn’t hear any noticeable change in the way it operated when put back together. After doing some more testing and getting some new cosmetic pieces i took it to a friends house to get some stuff custom fitted and see if he could figure out the issue. when we chronoed it, it had reverted all the way back down to its original 180-190 fps, he agreed that the problem has to be something with the gears as there the only thing that could really make a grinding sound and he told me he would swap them out for metal ones to see if that fixed the issue.
After a week he got back to me and told me he couldnt fit the gears he had into the gear box for some reason, and that he put it back together making sure everything was done right, but the blasters still only at about 200 fps… im lost, i think its worn down gears due to misuse, or an airleak somewhere, but most joints have been epoxied now and its still playing up, i was thinking of going to get some new metal gears from the retailers so there fit for the gen 8 nylon box, but im still not even sure if this will fix the problem so im here for anyone’s opinion, and guidance on what to try next.
I read alot today about the nozzle coming loose or just sealing that with epoxy which i have not tried yet.
and does anyone know why metal gears wouldnt grab the piston in a gen 8 nylon box but would in a Gen 8 ABS box? or is my mate just having me on and was probably too lazy to try it??
Thanks for your time
