Strengthened Trigger Spring for 1500

13 October 2012 - 06:13 PM

This is a really simple alternative to potting your trigger spring. This makes for a consistent trigger pull, whether you pull the trigger slowly, or quickly, it will release the air very fast. If you pot your trigger, the speed of your air release is completely reliant on the speed of your trigger pull. In a war situation where how fast you pull the trigger is usually the last thing on your mind, consistency is much more important in my mind. Not to mention, I feel the spring releases the air faster anyways.

Materials/Tools Needed:
-Dremel with a small sanding drum, or any other abrasive bit.
-AT3K pump
-Hacksaw
-Wire Cutters
-Supermaxx 1500 (duh)

Step one:
Take your trigger and grind it down with your dremel so it appears as shown. The two spots circled are where the trigger needs to be shaved down. What this does is allows the trigger to go further back, and allows the spring to "load up" more so that it stores more energy, and thus propels the rod faster for a faster air release.

Step two:
Cut down your shell to allow the trigger to go further back. There will be a little dimple in the piece of plastic that prevents your trigger from moving back. This is where you need to cut to. Any more is unnecessary. You must do this on both sides of the shell.

Step three:
You are now going to replace the trigger spring with a much stronger one. Remember all those AT3K pumps everyone throws out after replacing theirs? Well grab yours out of the trash, and cut it apart with your hacksaw at the seam. Take out the OPRV spring, and cut it down about 2 or 3 coils with your wire cutters. It may fly when it cuts, so make sure you hold on to it.

Screw the old spring off of the firing pin, and twist the new one on.

Sidenote: The old trigger spring works great as a replacement OPRV spring for both Panthers and Rangemasters.

Reassemble your gun and be amazed at the better trigger pull! Also, please don't turn this thread into a debate about potting trigger springs, I can upload a short video of the trigger working properly if anyone still thinks that potting trigger springs is effective. I'll even post a conservation of energy formula:
WNC + KE1 + PE1 = KE2.
Also, I don't have any before and after ranges, however the gun now leaves a bigger dent in a cardboard box than before. The spring can also overcome the force of a plugged pump blaster.

Dart Barrel fit Question

26 September 2012 - 03:28 PM

I decided to mod a PAS and I just did a simple PVC coupler mod, plus reinforcements. I started with about 13" barrels, continually cut them down and found the best barrel size for CPVC. My darts have a tight springer fit in CPVC. I wasn't quite satisfied with the results so I found a good barrel length for thickwall PETG in the same fashion. My darts have a loose airgun fit in PETG, if it were any looser, the darts would start to fall down the barrel.

tl;dr: I found optimal barrel lengths for CPVC and PETG. My darts have a springer fit in CPVC and an airgun fit in PETG

Why do I get signifigantly better ranges with the PETG? I always thought that looser fitting barrels were good for airguns, and tighter barrels for springers.

Bushing Darts

24 August 2012 - 07:15 PM

I posted this a while ago on NR, and figured I might as well post it over here for more feedback/if anyone else wants to try them out. These darts are essentially slug darts, with a rubber bushing instead of a washer.
This is what they look like:

They're just a tad bit larger in diameter compared to a #6 washer, and maybe a 1/4 of an inch thick. The construction for these is almost exactly identical to the safer style slugs in Ryan's thread.

First, burn a hole large enough to fit your bushing into. It's important to make this hole as centered as possible.

Next make sure your bushing fits into this hole, if you're inexperienced/unfamiliar with the size of the bushings. The bushing should be flush with the front of the dart:

Finally apply a felt pad to the front of the dart.

After testing these, the darts seem to fly just as straight as slugs if you're proficient at centering the bushings. The ranges also seem comparable to slugs, but in my opinion, these hurt noticeably less. Feel free to post any questions about the darts! No I did not find a McM equivalent of these BUT they may be purchased here!
