Step 3 Day 3, weapon rack completion and initial chassis assembly

The first task of the day was drilling the new mount holes in the weapon sprocket. I used the steel weapon hub as a guide for the drill bit and quickly added three new holes to the steel sprocket.

The weapon hub was bolted together and the 3/4" tubular steel shaft (1/8" wall, 9.875" long) was slid through the assembly. Two shaft collars were added to each side and the two bearing blocks were slid on the ends of the shaft. These bearing blocks were bolted to the front armor panel locking the assembly together. The weapon hub was centered on the shaft and the shaft collars were locked down at the hub and bearing blocks to prevent it from moving side to side.

The two inner side rails were slid onto the rear armor panel and the weapon rack was slid into the front. These four sections were then bolted together.

The last part of the day was the addition of the remaining hex standoffs and the baseplate. For the initial build the holes were mistakenly drawn to 0.250" diameter when they should have been 1/4" clearance holes. (0.266" diameter) This has been fixed for the posted drawings.
