Hello All,
I have T074 and have not been active on this site for about 4 years or so,
Check out the all machined track.
The segments are aluminum with a rubber tread.
The segments are connected with 1/8 inch diameter stainless steel pins.
There are about 1400 individual, machined parts.

Working on my metal tracks.
I have 5 feet assembled and most of the parts built for another 13
feet.
I have:
340 aluminum track segments with rubber pads.
340 drive lugs
100 stainless steel pins (need to build another 230)
80 track guides (need to build another 80)

Chris:
Yah, theres a slot for the rubber pad. I am thinking it would be
easy to scrape the rubber off, if it wasnt in a slot.
There is 12 different operations to make a single track segment, 320
track segments times 12 operations = 3840 individual operations.
1 cut to length
2 face one end square
Making tracks generally patterned after M60 tank track.

It has a tube magazine, with an air blast paintball feed assist.
You can see some of the shots break in the barrel.
