*For the radius'd areas,the formers will help 'acurrise' the 1/8th-inch poster board's contour ( I'm going to use for skin) and save on body filler and weight.Since these panels will also be fiberglassed,they'll also resist deformation while strengthening and stiffening.The tail boom of my Beechcraft Bonanza is constructed just like this,with very thin aluminum.
*Air won't be able to get inside any of the tail,so it will only have favorable wind and pressure playing across it.

DARKO reservation set/ new photos

Called over to DARKO and had Layne Christensen check his calendar for September.
We picked the afternoon of the 15th.This is the day of tech inspection for the 2017 USFRA World of Speed.Racing begins the 16th.
Anyone who shows up will have a chance to see Bonneville if they haven't already.You'll see some of Layne's work 'at work' out there,as he's been helping many of the teams dial in the aero on their streamliners.I'm gonna go at least one day.
Here are some recent images of the project:
*here you can see the new bed cover fairings which provide the formerly lacking edge radii needed for the ring-vortex.Also,the 'trunk' opening in the new boat tail ,

for enroute storage of the stinger and fake Dodge Viper windshield.
*Here's with the stinger re-attached to get a sense of the 'trailer' length

*This is the scuttle opening in the floor of the boat tail,which will have a removable panel which lifts up and out to reveal the opening.With both car ramps,I'll be able to step up and over inside and down through the floor of the tail,onto the wind tunnel floor,allowing me to lift the boat tail off Spirit for a tailless measurement.
Here is a 11/16th-18 tpi tee-nut and hand-bolt I'm using for the 1st time.These will allow blind attachments without fear of pull-outs or fastener spins.
I've been able to work (on the days it doesn't storm) 'til around 4:00 PM,when the heat index hits 105F,then it's time for a shower and inside the house cool down,'til 7:00 PM,when I can go back out and do yard work until 8:30 or 9:00.

Beautiful integration onto the Campmobile!
Does it have the forward diesel engine or rear wasserboxer?

All the Vanagon style bodies (T-4) rear rear-engined. The T-5 is front-front.

l'il update

The skinning process is proceeding.I've begun with the really-curved surfaces first.
I'm using 'project board' from Dollar Tree.It's a single thickness cardboard which I force over the edge of a sawhorse to create a pre-bent panel to wrap around the radii.
I tack it in place with 3/4-inch nails,mark for cutting,plus nailing lines,pull the nails,make the cuts,then hand nail on 2-inch centers on straight runs,and 1-inch centers around curves.
The outer surface of this skin will establish where I flush out the foam board which will fill the more flat areas.
I'll dope all this,both sides,with polyester resin,then do a single layer of glass on the outside.
I'm trying to keep the weight down.So I'm not gonna go crazy with body filler,and try for a 'factory' appearance.If the numbers look good at DARKO I'll be willing to invest more in aesthetics later.
All these surfaces will be submerged in a couple inches of turbulent boundary layer and I don't think cosmetics will make much difference to drag.
-------------------------------------------------------------------------
I went through a dress rehearsal for dropping the stinger and tail and there were no ugly surprises.Whew!
I got an 11-ft by 19-ft tarp on sale at Harbor Freight and rigged up extra shade and rain protection for the power tools.
I throw a door over a couple of sawhorses to create a makeshift work surface for the chop-saw and portable table-saw.
A large hack berry tree provides some additional shaded work area.(shade-tree mechanic)
I've been getting at least 8-hours of comparative analysis done each week at a local donut place.I get there at 5:00 AM and have a tall bistro table to work on while I poison myself with sugar,sodium, and nitrites.These aero numbers will help me understand where Spirit stands with respect to other vehicles.Where I started from and potentially where I can get to.
As of 2014,Spirit had identical drag to GM's 1982 Aero 2000 (Epcot) car and a little better than Kamm's lowest drag K-car.
Spirit's overall drag index (7.7575 sq-ft) was basically identical to a 2015 Lamborghini Huracan LP 610-4 and lower than A Chevy Sprint and Toyota Starlet.Her mpg is impressive compared to them as well.
I'll have more on this sort of thing as I get materials better collated.
Sleep is gonna be weird until this trip is behind me so I just 'work' when I'm awake.

Photobucket ate my homework! But I guess you saw it.
