Well we did it, we drilled holes in our nice expensive 50cal rounds :O
The first round gets drilled, we did pilot holes first before drilling out to 7mm.
1, 2...miss a few hours of drilling, measuring and working how to get the feed tube spring bend nicely through almost 90 degrees in the first round. We also drilled two holes in the first round and put two screws up from the feed plate so the round is held in position nicely:
We rig up the tube to feed from an M4 hicap
MadDog drew a picture of Hitler and I made sure I shot him in the face... a few hundred times:
Really should have shortened that video, oh well :P Becasue we've had a counter rigged up to the system we pretty know how many times the gun has fired (mainly dry firing) - we estimate that so far it's done in the region 10,000.
So with the feed workingfine next step was to drill even more holes in the rounds and pass the air-line in:
The idea is the belt of rounds will lie across the top of the ammo tin, one row dow - so it looks fairly full. The rounds that go to the gun will fold over and in so that the tin can be shut. They'll be two types of ammo tin: For the field version, it'll hold a small HPA tank (1litre or 1.5litres) and a custom built feed/wind system. The vehicle version will be just a huge hicap with the air-line tube passing out the bottom. The vehicle version is what we're doing here. Which reminds me; we got the 15litre tank for the Land Rover, it's mounted up and ready to go but I forgot to take pics. Will take some pics for the next update.
Roughed together so we got an idea on what it'll look like (any excuse :P):
We started working on the feed cover catch, just need to do the other end of it and we'll have a closable tray cover:
