LEGO TECHNIC INSPIRED RC TANK

Last crawled date: 4 years, 2 months ago

For this tank:
80EA Tracks
2EA Track Structures
4EA Drive Gears
16EA Pulleys
80EA Pins (I used nails)
Regarding the pins/nails I used:
Nail = 0.082" diam
Head = 0.200" diam
Length = 1.25"
While twisting the nail with a pair of pliers, I pushed the nail thru the track pieces and then cut the nails to length. The cut produces a small amount of 'squish' to the nail which prevents it from coming out. It is a snug fit, as the track is used it looses up.
To rapidly looses up the joins, I drove the assembly with a drill in both directions for a few minutes.
I drilled out the holes in the structural pieces with a 3/16" drill bit, only where the pulleys were used. You can do them all, it's just not necessary.
I added hot glue to the tracks to increase traction.
The rest of the pieces I used from my lego technic collection.
