Playing Ketchup Episode I: Stinkin' Feet

Its been four months since I've posted any updates to my R2 build - mainly because I've been concentrating on actual building while letting the posts slide. But today its a balmy 20º, snowing and I'm taking a day off work after a nearly 90 hour work week. So get ready for a couple long posts of progress.

I'll start where the last post left off - getting the NPC motors finalized for installation. I ran into the same problem everyone did with the old battery boxes and had to grind the tops of the NPC motors in order for them to fit inside the boxes. I also had to modify the openings of the left box a fair amount to get it to slip all the way over the motor. Not sure why the right one didn't require it, but I'm fine with only cutting one box if the other one works.

At this point I was done with the NPCs but needed to do more work on the Battery Boxes. I wanted to make sure the Battery Harnesses were going to be secure, so I drilled a hole into the harnesses and the boxes at the bottom of the main vertical piece, where the decorative cover would eventually cover the unsightly screw. I had to do a bit of sanding on the harnesses to get them to fit in the box facade as well. My boxes are from an older run before the face of the box was CNC'd. So they are not quite exact, and you can tell just by looking at them. Eventually I'd like to replace them with the newer improved version.

At this point I was looking at the issues of securing the boxes to the feet. The curved inside panel of the feet have holes for a screw to slide into as you can see in the pic below, but after a lot of staring I realized the boxes were such a tight fit that I'd never be able to get box mounted screws to slide down in the pre-drilled foot holes. I did a little searching on the forums, and decided to drill two holes at the bottom of each box and foot that a screw could pass through and be tightened from the bottom. Drilling into several hundred dollar parts is always scary and this was no exception, especially because of the curved area where each hole needed to be.

Its a tight squeeze with the fingers, but it works quite well. In the end it turned out very good, and the boxes are rock solid on the feet.

The final piece to the feet puzzle was drilling out the holes for the Knurled Hose Fittings. After even more research I went to Harbor Freight and bought a step down drill bit. It was money well spent and made expanding the pre-drilled holes quite easy. Going from 1/4 inch to 11/16th took only a few minutes on each hole and the KNFs slid right into place.

At this point its was nearing late November and I was ready to break everything down for paint. Luckily it was an unusually warm December, and the added help of a propane heater didn't hurt either.
