Early design. Kind of stubbier than the final product with different windows
Finished design. Exactly 10' long and 42" tall. We are hoping it will go between 45-50 mph.
Just some playing around for logo placement. The vehicle is called "Battle Born". It's UNR's 25th anniversary of entering into the competition.
Original foam "positive" of mold
Applying a coat of surface primer to bottom
Applying a coat of surface primer to bottom again
Near-finished top plug - needs to be smoothed down.
The workshop in Palmer Engineering
Finishing touches and surface spray
Death from above!
Mold release being applied to bottom plug
Shiny and smooth
Next is a surfacing epoxy resin.
Have to apply a thin layer to the whole thing
Probably 45 minutes later...
It tastes just like marshmallow spread.
Next is two layers of fiberglass. We apply some colored blue dye to tell whether we have one or two layers.
After that, we have to hammer out some tooling foam. It's a light-weight, claylike material that adds rigidity to the mold.
Have to apply it all over - this took hours.
Should NOT have started this whole slide show at 7:00 PM. I think this was 1:30 AM by now
One more coat of fiberglass and resin
The finished bottom mold! We'll see how it turns out
Had significant trouble getting the mold out. It involved hammering...
But the key was jumping. Up and down. A lot.
Boom! Our finished bathtub.
Looks like our measurements were about right.
Some more sanding on the central channel with Colleen and Austin
The finished channel - pre-wet sanding
Machined aluminum front wheel support and foam plugs for mold.
Lots of carbon cutting. This hurts the wallet at $45/yard
Final preparation on the mold
First layer begins - carbon/kevlar weave for abrasion protection.
Bottom surface covered in carbon/kevlar.
