Nyper build thread

Took 3/16” off each side of the front arm. I took off more than I had originally planned so I could use a bushing with a flange to keep the arm from possibly rubbing the frame tube.

Had some steel bushings laying around I made work for now. Eventually I’ll make aluminum ones for final assembly.

And for the first time since starting this project I bolted the rear suspension in. There was a period in the last couple years I thought I’d never see the day. Feels good.

I want to shorten the tunnel about 5” more and taper in the sides. Mostly for looks as I don’t like how it’s squared off and I want to end it right after the cooler. First I’m going to install the track, drivetrain, front suspension, steering and get it sitting on the ground so I can get a better idea of what it looks like and see if I want to change anything before sandblasting it.
 

Now that I have a chance to see it with the suspension in I wish I would have tapered the lower 1” tube up more and just did a straight tube basically following the orange string line.

The tunnel weight from the bulkhead (vertical 3/4” tube) back is 14.73 lbs. Here’s the breakdown if anyone is curious.

3.54 lbs - 72” of 1 x .058 round
3.45 lbs - 122” of 1x1/2 x .035 rectangle
3.81 lbs - 169” of 3/4 x .035 round
1.17 lbs - 81” of 1/2x1/2 x .035 square
2.03 lbs - running boards
.47 lbs - front suspension mounts
.25 lbs - rear suspension mounts

If I did a straight tunnel with 1 x .035 for the lower tube(instead of .058) and used 3/4 x .035 for all the remaining tube and did more of the traditional truss style frame I figured I could do it for about 13.5 lbs, didn’t save as much as I thought it would. Only way to really drop weight would be a carbon fiber tunnel with some tube to pick up the suspension mounts.
