Awesome, some great information and certainly allot to digest there.
Starting to notice there’s a few similarities between getting a firearm to shoot the way you want and a gel blaster to do the same. Both seem to require some trial and error, trips to the range (or back yard), ammo testing and so on. In saying that sometimes you get lucky and things just work.
RokSolid appreciate your post with the Bradley Phillips YT references.
An M90 spring is in the post which was ordered before reading about the uneqeal springs, I’ll have to keep that in mind for the future. Again appreciate that nugget of knowledge.
Coincidentally I happen to own that hop-up you linked however I believe the wrong tongue is installed. Its the older style with the narrow cut outs. My son has the Aztech Hellfire on his blaster so we can try that on mine too. I cut 8mm off his barrel to get the hellfire to fit properly.
When the M90 spring arrives I’ll swap that out, fix the hop-up to the correct Tongue and see how I go.
Yeah, can associate with @Maiphut about these de-burring tools.
Wasn’t life great back in the old days when we could spend good money on buying British/Japanese quality equipment
Nowadays the same original old school tool makers are all getting their products made in China……… and there’s very little industrial quality stuff available on the market anymore
P&N or Sutton… I avoid anything made in China if I can.
There was a time when steel tooling items were made from decent material and if they were black they were nitride coated… like gun barrels, etc.
The last set of turning tools I got from ebay (carbide insert holders) arrived and almost went straight in the bin.
I swear they were made of mild steel, painted black not nitride coated, which included the screws and clamping blocks that were definitely not high tensile.
Just remembered we have an RCBS case deburring tool that would have worked better than the sandpaper, or at least be easier to use. Nevermind, next time
Used to be a knowledgeable fellow on the GBF that knew the ins and outs as he sold tools. Would have been good to have the input on this subject. Oh well.
Downgrading to an M90 spring has knocked the FPS down to 300-310. I’ve put the correct tongue on the ihobby hop up as well and done some more testing but unfortunately the accuracy is still pretty woeful. I’d say 2m spread at 25m.
Put my son’s Aztec Hellfire hopup on which saw an improvement of maybe 1.5m spread at 25m.
Have tried 4 types of gels and results were similar so I feel as though it’s the setup and not the gels.
I’ll do that barrel cylinder measurement at some point and see what that looks like
As a general rule, we usually check grouping accuracy with gel blasters using full auto or burst fire… which means all that vibration will transfer to anything loose and gels will be all over the place. I’ve found 90% of accuracy issues I’ve had have resolved with a bit of work on a solid setup.
VE is important, but once you get over a certain length with the inner barrel, you’re pretty much stuck with what you get, dictated by rhe cylinder size. Bad VE can be improved with tighter bores, porting, etc but on something like an M16A1, M14EBR or L1A1 with a long barrel over 50cm you’ll never get optimal VE.
For what it’s worth, I’ve built blasters with what should be appalling VE and they’ve been very accurate. I’ve also built some with perfect VE and they haven’t been accurate at all. It’s a bit of a crap shoot.
