Mini homebrew modifications *Do So At Own Risk*
 
It seems there is a growing number of small upgrades you can do to the Mini to increase the user friendliness of the marker. They may not change performance or efficiency, but they make general maintenance and adjustments easier. In this thread, I hope to share my findings to help others make the Mini more user friendly as well.

If you would like to add a homebrew mod, please include necessary tools, steps, and parts that are required, along with good quality pictures. it helps to set your camera to the 'macro' setting for close up shots.

This thread is not for adjustments or aftermarket accessories, such as buying new bolts, adjusting trigger pull, or dwell settings. Those are good to know, but belong in seperate threads.


Just because this can't be stated enough (Thanks Crede! :tup:):

Trigger magnet mod
 
I don't know who the original poster was of this mod, but here it is again for your reference.

Level of Difficulty:

Low

Cost:

Approximately $2

Materials needed:

Package of two rare earth magnets, round, about 1/8" tall. Found at RadioShack

Directions:

1. Locate the exposed magnet that sits directly behind the lower trigger adjustment screw (the rear stop screw).
2. Place one of the rare earth magnets you purchased on top of the exposed magnet (the magnetic force should attact them)

You do not need to glue the magnet in place, the magnetism should do well enough

Feedneck thumbscrew
 
Original writeup from RobertSims at PBN

Level of Difficulty:

Medium (provided you don't loctite the wrong item, everything can be reversed to stock, even after you are done)

Cost:

Under $10

Materials Needed:

-A clamping knob with female insert size 8-32
-Threaded rod size 8-32 (this is also called allthread). You should only need about 2 inches, but it's usually sold in 3 feet. Find a bunch of Mini friends and spread the wealth!
-Hacksaw with a metal cutting blade (You could use a Dremel with a cutting wheel, but it doesn't work as well - slow and easy wins the race)
-two wooden blocks
-Vice
-Red Loctite
-(optional) tap and die set

Directions:

1. Place the threaded rod in the vice between the wooden blocks. The blocks help prevent the threading from being damaged.
2. Using the hacksaw, cut the threaded rod down to approximately 1 1/4"
3. Disassemble your stock feedneck's screw, brass nut, and clamp.
4. Using the 1 1/4" long threaded rod you just cut, try to screw one end into the clamping knob, and screw the other into the stock brass nut that sits inside the clamp. If at any point it becomes hard to thread, use the tap and die set to correct the threading on the threaded rod.
5. Disassemble everything in step 4, then reassemble it on the feedneck. Test to see that the threaded rod is the correct size by testing the clamp's full range of motion and ensuring that the feedneck can be clamped down far enough. If needed, go back to step 1 to shorten the rod.
6. Disassemble everything again
7. Add A LITTLE red loctite to the hole in the clamping knob, or on the portion of the threaded rod that will screw into the clamping knob. Screw the clamping knob onto the threaded rod and let it dry overnight.
8. Assemble the new thumbscrew you have just made, the stock brass nut, and the clamp onto the feedneck.

Notes:

-Your best friend is patience, a straight cut, and knowing that you can always make things shorter but not longer.
-With my personal project, my threaded rod extends just under 1" from the knob. You might decide longer or smaller is better
-On my first try, I decided that things would look better if I rounded the edges of the knob that would butt up against the feedneck so that the knob would have a better fit into the countersink of the feedneck. Unfortunately, with the knob I have, it just ended up looking bad because I wore the plastic down to the inner metal of the knob. Even if that had worked, getting back to a polished finish on the plastic is beyond my knowledge. Just leave the knob the way it looks, it's fine.

Can someone shed some light on the magnet/trigger mod? Does it make the trigger more responsive?

Uziel Gal 01-10-2008 09:44 AM

It's basically going to make the trigger pull heavier, or more importantly, increase the return strength.

Some people won't like that of course, because they assume lighter has to be better, but if you can get used to the heavier pull it's actually an advantage - trigger bounce is less likely, and the quicker the trigger resets between shots the quicker it is ready to be pulled again.

Here's a minor suggestion for the feedneck mod: buy a rubber grommet (usually found in the same aisle as the knob) and put that between the nob and the feedneck to prevent scratches. It works fine for me.

I like it lighter, you need lot of time to get use to heavier
