Armrestling

Standard

Continuing with the interior, I decided to emulate the arm rests of the 037. Actually they are more like door pulls, there’s not really any place to rest your arm. Here is a photo of the stock 037 units for reference.

IMG_4411

The stock Scorpion units I started with are similar but different, they look like this.

The upper piece is similar, but the door pull/armrest is a separate piece. So starting with these pieces, I removed most of the armrest portion, leaving the forward mounting screw location. Then I determined a new angle for the door pull, since these pieces have the door pull angling downward too much to clear the side bar of the roll cage. The two pieces were then epoxied together, and covered with a couple layers of fiberglass.

IMG_2570

This was smoothed out a bit where needed with sanding and putty epoxy, then covered in lightweight body filler to arrive at this point.

Repeat for other side.

IMG_2572

Then a new mounting location for the lower part of the door pull was added to each door. The original mounting point is the caged nut below and to the right.

Some paint and then they were test fit.

I just need to get the proper allen headed screws for the lower mounting point, and these are done.

Dashing. Simply Dashing.

Standard

Work lately has been focused on the dashboard. With the center console complete and in place, I could design and locate the dashboard. I started with an aluminum T-bar frame.

IMG_2517

The small piece of split PVC tube is there to simulate the curve the lower part of the dash has, and get the spacing to the center console correct.

After the distance outward from the windshield was established, the legs that tie the “face” back to the car could be created and tacked in.

IMG_2518

My aluminum TIG skills are, uh, limited, so I used a spool gun feeding aluminum wire. Messy but effective. Here is the final frame, complete with the tabs that will mount the instrument cluster.

IMG_2519

Then PVC sheeting was used to cover the top of the dash. It was sheet metal screwed in and epoxied.

IMG_2522

Also visible in the above shot are the PVC tubes which have been split lengthwise and are epoxied onto the stem of the T-bar. The cluster was mounted and the entire thing test-fit in the car.

IMG_2525

With that all looking good, the whole thing was covered in a skim coat of lightweight body filler.

IMG_2527

That was then test fit back into the car. I must have taken things apart and put them together dozens of times.

I found the ends of the dash needed some extra pieces to cover an area near the windshield where there was a gaping hole so I added those.

IMG_2535

The area in between those wings is covered by part of the HVAC system, where the air is directed to the windshield.

IMG_2540

Finally the entire thing was assembled and plugged in for a test.

IMG_2539

All good! Some small vents were added to the holes at the ends of the dash and it is complete. Pardon the grainy, odd lighting, I was using the flash on my phone.

IMG_2542

IMG_2538

Not a bad imitation of a real 037 dash, shown below for reference.

I do need to create a glovebox area next. And look into getting the whole thing wrapped in suede.

 

 

Consoling news part two

Standard

So the more I looked at the console, the less I liked a couple things about it. One was what I mentioned in the previous post, which was that the texture treatment did not come out to my liking. Another was that the “reveal” around the upper two plates (hazard switch plate and circuit breaker plate) was not to my liking. I’m talking about here.

IMG_2511 with arrows

So I pulled the surround back off and removed the fiberglass, then sanded it back smooth and painted it. That’s how it sits now while I contemplate options. Ultimately I think I like the suede trim in the first picture of the previous post the best, so I think I’m going to talk to an upholsterer to see what it would cost to trim this surround and the dash that way.

The other thing I did was work on the metal frame that houses all the things in the console. I brought the metal further out to the upper two plates to fill the gap better. Here is how it sits now.

IMG_2516

I think the time spent was worth it. I also tried my hand at creating the ideogram lens for the right side climate controls, which control fan and the windshield/vent air flow. I used some dry transfer decals intended for model railroad stuff on some polycarbonate sheet. The decals are actually sandwiched between 2 sheets of polycarbonate, epoxied together at the sides, so they can’t get scratched up or dirty. I’m pretty pleased with how they came out.

I can’t do them for the other side yet, because I have not determined how the cables will operate. Once I know whether top and bottom represent heat or cold, fresh or recirculated air, I can create those. Next up for these is modifying the stock Scorpion fiber optic lighting harness to illuminate these lenses.

Consoling news

Standard

I’ve been working on the center console, which includes (top to bottom) hazard switch and possibly power window switches (or ashtray instead), circuit breaker panel, HVAC controls, clock and a couple of switches. Here is a shot of a real 037 center console, this one with an ashtray (from the X1/9, also the clock is from the X1/9).

IMG_4403

And here is the center console I have been working on. Mine will have only the hazard switch, and if I ever install power windows those will go on either side of that switch.

IMG_2501

I’ve also been working on the surround for the console. 037s have either the suede look dashboard, or something that resembles fiberglass weave. I’m told this is actually a neoprene-like foam, but I have never seen a real 037 in the metal. Here is what the foam type dash/center console look like.

16797107_1441257542574951_8378254944788912370_o

So I set about making the surround out of PVC tubing. Yes, there will be plumbing supplies on board my car. I started with a tube frame, then added PVC sheets to fill in the sides. Lightweight body filler was used to cover and smooth everything.

IMG_2503

Some filling, sanding and time brought me here.

IMG_2506

Then I used some spray adhesive to apply a layer of fiberglass, to provide the texture.

IMG_2508

And when finished, it looked like this.

IMG_2510

On the back side, there is aluminum angle with bolts protruding, to mount it to the circuit breaker, switch and HVAC panel. A light coat of fiberglass resin was applied, then gray paint. It was then all mounted together and test fit into the car.

IMG_2511

I have to say at this point that I am not satisfied with the texture treatment, it seems way too lumpy. The substrate was meticulously smoothed, so I’m not sure where that comes from. I am thinking about ways to re-smooth and reapply the texture, but for now it is what it is. It kind of reminds me of that gray foam they pack things in. Not good, it will have to change, but that’s for another day.

One clever thing I added was a re-purpose of the clock. The upper dash already has a clock, and I wanted to keep this area as authentic as possible. So I used the proper X1/9 clock, but gutted it and mounted my old PLX Devices wideband A/F gauge behind it instead.

IMG_2513

I have some finishing work left, to be sure. But aside from the texture issue, I like the way it has turned out so far.

 

Face and butt

Standard

One of the sidebars of trying to get the electricals working is that everything that needs juice has to be in place so a wire can be run to it. So headlights, fog lights and blinkers had to be put in place. The car looked kind of toothless without the grill, so I made up mounting points for it and got that in place as well.

IMG_2479

Then on to the rear. Fiberglass pods were constructed to mount the taillights to, and they were put in place. Then I created the rear grill out of 1″ x 1/8″ aluminum. Here’s where that’s at right now.

IMG_2489

The left taillight looks like it’s sagging a bit because the nuts holding it in are not tightened yet. Still lots of finishing work to do back here, and more fiberglassing to give the grill better mounting points but still be removable.

I also played around with a modified X1/9 rear valance grill, just to see what that would look like.

IMG_2482

I really like the look of that in flat black instead of body color. I might run that when I feel like running the alternative taillights I made for the car when it was a Scorpion.

DSCF0071

At this point, the electricals are very close to being done. I still need to finish the rear harness, install the license plate light, wire the hazard switch, and wire/install the front side marker lights.

 

Front wiring harness done

Standard

The harness forward of the bulkhead has all the wires in place and tested. I haven’t bundled/wrapped the wires yet, that will be the last thing I do. The front harness supports the wipers, blinkers/hazards, parking lights, headlights, fog lights, and horn. Oh, and the wiper fluid bag motor.

These circuits all come through this bulkhead connector.

IMG_2475

They split and run down the left and right chassis tubing.

IMG_2477

The wiper circuitry is not in its final home yet, that’s the bundle of wires making their way over the scuttle trough. The will be routed through the scuttle wall eventually.

The front harness was all ready to deliver electrons, but had nothing to send them to.  So I started on making a place for the front lighting. I built fiberglass boxes for the lights to mount to, a larger one on top for the headlights and a smaller one below for the fog lights. The blinker is light enough to just hang on the front fiberglass with no extra reinforcement.

IMG_2473

With that stuff done, I could create the mounting points for the lighting. Hey, this thing is starting to look like it has a face!

IMG_2471

Well, half a face. I need to duplicate for the other side. And the grill is just sitting there, it’s not mounted yet either.

 

Bored of wiring yet?

Standard

I might get there soon, this is a time-consuming activity. Yet I find it somehow enjoyable. Being a software engineer by trade, I find it somewhat akin to programming.

I have a secondary relay panel started and mocked into place so I can determine wire run lengths. This panel contains the relays for:

  • Headlights
  • Fog lights
  • Radiator fans
  • Blinkers/Hazards

The backside will house the relays for:

  • Horn
  • Wipers
  • Blower motor

Although currently only the horn relay is back there. Again, the purpose of all these relays is to keep the high-amperage current off of the 40+ year old switch gear.

Here is where the panel mounts, high on the passenger side kick panel.

IMG_2323

Most of the circuits that connect to this run to either the switch gear or the front of the vehicle, although a couple circuits (blinkers for example) run to the rear of the car.

The front bulkhead connector both brings power in from the battery (for the “load” side of the relays – headlights etc.), and carries the power back out. It is just to the left of the relay panel, high up in the passenger footwell area.

IMG_2325

There are a few more circuits to add to this side. Nothing has been added to the front side yet except the main power in.

IMG_2326

So you can see the front harness is not even started yet. First I’m going to work on the switch gear harness. This will interface the driver controls to the fuse box and the secondary relay panel. It will include circuits for the blinkers, lights, horn, and eventually for the wipers and blower motor.
