Here she is: Miget
The name comes from a little play on its original name "Megatron Gen. 2 Tribute" or "MgtG-2T." That was annoying to say though, so since the first part is "Mgt", I decided to call it Miget.
I realize that some people don't like linked triggers, but I do, for the most part. The big problem with linking the trigger of a mav or similar blaster (like the DTB) to the trigger of an LS is that the LS has a tiny trigger pull, but the mav has a long trigger pull because of the rotation of the turret being part of the pull.
I fixed this problem by giving the LS a longer trigger pull and slightly shortening the pull on the mav.
Here's a look at the internals (minus plunger tubes and such):
Now here's a closeup of the LS trigger:
Notice how the long part coming from the trigger has been shortened and the groove of the trigger has been lengthened. The actual trigger has also been lengthened.
Here's a closeup of the mav trigger:
There wasn't as much done on this end, but to make sure the rotation worked fine, I added two return springs. I also added a bit of JB Kwik to the part of the trigger that moves this catch, which makes the gun fire sooner. Since the gun fires sooner, I also had to modify the rotation gear to make sure the turret was in place to be fired. To do this, I shortened the back half of the gear and sanded the back of the teeth on the front half. I am not going to go into a lot of detail here unless someone actually plans on replicating this, then I will try to help as much as I can.
The two triggers are linked with Spider-Wire fishing line, which is amazing stuff. It doesn't stretch or break. This was the only suitable type of line I found for the job. I tried many guitar strings of differing gauges and other fishing lines, but they all either broke or stretched too much. The guitar strings also gave a very hard trigger pull. The line is also run through little pieces of pipe to keep it from getting shredded by the shell.
Both of the guns have the typical mods done to them. Mav has a LS frontgun spring added, improved seal, ARs removed and cocking bar reinforced. The LS has an LS/BBB/RFSG spring combo in it, an Angel breech, added o-rings and reinforced catch.
There is something about the Angel breech that I changed though. I have never seen anyone else do this, so I will post it up. The little orange nub that was glued to the 19/32" brass kept breaking on me. I used fishin' glue and I tried letting it cure for a long time before using it, but even with just the LS/BBB springs, it would break after a magazine or so worth of shots. Because of that and something that Forsaken told me while I was in Canada, I decided to get this thing working better.
I sanded down half of the original barrel and sanded down the edges, so the mags could fit over the breech still. Now, even with the three springs I have in there, it hasn't broke after loads of firing tests.
RANGES:
I know that someone will inevitably ask, so I will just post them now.
LS: Average 90'
All tests were done outside with no wind in ~40* weather with felt-tipped stefans weighted with 3/0 fishing weights. I measured the spacing of the parking lines and then counted lines. I also shot at CNP and hit her in the middle of the back 3 out of 4 times from 72'
Mav: Average 35'
All testing was done indoors with felt-tipped stefans weighted with a single BB. I measured these ranges with a tape measure. It's not as good as I'd like, but hopefully I can get it shooting better with one of Lt. Stefan's springs.
I also made a shotgun grip for this, but I may not use it. I made it from steel, so it is quite heavy. Also, I have elbow troubles from a motorcycle crash a few years ago, so priming a high-powered gun with my left arm repeatedly makes it hurt quite a bit. With the regular LS priming mech, it is easier to just grab the handle and then push forward with my right arm.
Hopefully my trigger-linking technique will be useful for someone here. Also, if anyone wants pictures of the shotgun grip I made, I will post some.
