Dash and Custom Wiring Harness – Part 2

Before installing the dash we wanted to complete the installation of the front courtesy lights as they are not easy to access without the dash, much less with dash in place. We also completed the wiring and testing for the pedal brake switch that can also be seen in the photo below.

LH front courtesy light

We then covered the front aluminum cockpit molding with our red vinyl and installed it on the body. It looks quite handsome.

Just to add a touch of bling to our work the chrome rear view mirror went on next. Two chrome oval head #10-32 x 5/8″ machine screws secure the mirror to the captured nuts in the body.

We then added the rear cockpit molding:

We then installed the LH demister hose to the elbow and nozzle vent. We will be using an AFR gauge to assist with tuning but do not plan to leave it in the car permanently so we ran a red wire from fuse position #19 in our fuse box, through the firewall an into the interior. This wire can be easily removed after we finish tuning.

We then began the actual installation of the dash with all of its wiring, gauges, switches and etc. in place. We had seen a tip on the internet to make this task easier. That is to use large zip ties to support the corners of the dash. This allows easy access from above for mating Deutsch connectors, finishing up with a few loose wires and for running cables through the dash and the firewall. As it turned out, it was a great tip and made the job quite a bit easier than it might have otherwise been.

Dash with zip ties to the body

We could then gradually tighten the zip ties and move the dash closer to the body. Ultimately, we cut the zip ties and inserted the 1/4″-28 – 1″ hex head bolts and tightened each corner.

Care must be taken with three items 1. one must keep an eye on the steering shaft so that it remains free in the column bezel. 2. There are two braces under the dash that secure the dash to the firewall. The braces must be above the lip that they mount to on the firewall before the dash to body bolts go in on the corners, otherwise they are difficult to properly position. This is especially true in our case since the braces serve as the platform for our supplementary switch panel behind the dash. 3. Routing the capillary tube for the water temperature gauge and the copper pipe for the oil pressure must be approached cautiously to avoid damage to either.

The installation of the individual items associated with the dash is covered in the attached video. Once we had the dash in place we began testing all of our circuits. Everything seems to functioning properly! A major achievement in the process toward assembling the Bugeye.

Demister Elbows. We installed a few more items on the car. The demister elbows were a couple of easy items to install.We also installed the demister hose on the RH passenger side of the car just to check fit with the windscreen wiper controller.

The coolant overflow tank was the next item to mount on the car. It is located on the LH radiator brace. 

Coolant Overflow Tank

We were going to paint the bottle cap a color to signify that the container was for coolant and not a oil catch can, but we found this little sticker to go on the cap that will work just fine.

Then we added the bonnet rubber buffers. These buffers sit on aluminum blocks and are secured to the car with one #10 -32 x 1/2″ machine screws with washers. There is also a steel bushing or spacer inside the rubber buffer to keep it from compressing too much.

We then installed our fancy battery box sourced from Speedwell Engineering. A further explanation of the box and the installation process may be seen in a post made under the “Personalizations” category: https://valvechatter.com/?p=14483.

It was then time to install the rear license plate body plinth and light. This was a pretty straight forward job with little difficulty with satisfying results. These are the components involved:

Our next project was the installation of the front cockpit aluminum trim. In our case the trimis not polished or anodized but instead is covered with vinyl matching the interior. We used contact cement to secure the trim piece to the vinyl and mounted the finished product to the body shell with nine oval head #10-32 x 3/4″ machine screws. The two outside screws will ultimately be used along with a “P” clip to secure the bristle flex trim for the doors openings.

Sometimes adding a little chrome bling just needs to be done, so we added our chrome rear view mirror purchased from Bugeye guys. It is fastened to the body with two stainless oval head #10-32 x 1/2″ machine screws.

Continuing the theme of attaching more shiny parts to the car, we mounted the rear cockpit molding. We used chrome oval head #10-32 x 3/4″ and 5/8″ to fasten the strip of aluminum to the body. Unlock nuts were used to keep things tight and in place.

We want to use our AFR gauge to help with initial tuning after we get the car on the road so we added a temporary red wire parallel to the main harness from fuse position #19 in the Classic technologies relay/fuse box. We will pull out the wire once we have the car running the way we like!

Fire in the Hole

We had planned to run the engine on the starting stand with the gearbox fitted, but thought better of it. First, it would mean that we would have to figure out a way to keep the driveshaft fork in the nose of the gearbox so we would not leak oil out the end. However, more importantly, we wanted to inspect the clutch and the ring gear. So we modified the starting stand to include a mount for the engine rear backplate. 

We then hooked up the choke cable to the carb and we installed a lawn mower throttle cable and slide controller on the control panel and also hooked it up to the carb. These are shown in the video with the link below.

Water was then added to the radiator, Valvoline Racing Oil 20W-50 was added to the engine and some automatic transmission fluid was added to the HIF-44 damper. We then disconnected the coil and spun the engine with the starter until we had oil pressure. After checking ignition timing one more time, and testing for spark at the plugs. It was time to fire it up. It ran pretty well but seemed a bit rich at idle.

After a pause to work on other projects and to wait for parts, we came back to the engine to try to improve the engine’s tuning and to check on the clutch and ring gear.

The clutch had worked just fine but we decided to go ahead and replace the disc and pressure plate since the engine was out of the car. While we were at it, we also made plans to take the flywheel to a machine shop and have the face resurfaced and have the flywheel and clutch pressure plate, or cover, dynamically balanced. That is when things got interesting!

We took the flywheel to Southwest Hydraulics in Venice, Fl for resurfacing, but we got a call from them indicating that the flywheel was “coming apart.” As it turned out the flywheel had been lightened a bt too much and there was very little material between the flywheel lip and the ring gear. See below.

Flywheel delamination

This is going into the trash!

Since they no longer make steel flywheels for the 1275 (aluminum lightened flywheels are available) we searched eBay and located one. It had not been lightened at all which we preferred, but it was not without its problems. One of the clutch cover bolts had been broken off in the flywheel. Fortunately, our friend Randy Forbes came to our aid. Using his milling machine, he first flattened the top of the bolt shaft and then with his drill press using a LH drill bit he was able to remove the broken bolt with no adverse effect. Thank you Randy!

We then took the flywheel back to Southwest Hydraulics for the resurfacing and we also had them replace the ring gear with a new one sourced from A.H. Spares

Flywheel resurfaced

Then it was off to “VAMI” – Venice Auto Marine machine shop where we had the flywheel balanced. Unfortunately, we could not balance the clutch pressure plate with the flywheel because the center hole in the pressure plate was too small to fit on their machine. This should not be a problem as the pressure plate comes balanced by Borg and Beck. The new disc was sourced from Rivergate.

We then reinstalled the flywheel, clutch disc and clutch pressure plate. The flywheel bolts were new and torqued to 4o ft. lbs. A locking tab washer was installed and all the tangs were bent over. The clutch bolts were torqued to 19 ft. lbs.

In the meantime, we replaced the metering needle that came with the carb with a “BDL” needle to get some additional fuel at start up without having to rely so much on the choke. Randy Forbes again came to our aid with the installation of our oxygen sensor.

Oxygen Sensor Bung Installed

Randy doing his thing!

He installed a bung into our new exhaust pipe for the  oxygen sensor so that we could use our newly purchased Innovate Motorsports AFR gauge. This is very helpful in adjusting the fuel mixture at the carb.

Before starting the engine a second time we also decided to replace the original-type Lucas starter with the gear reduction starter we had. 

We then started the engine a second time and we were pleased with the changes that had been made. The engine seems to be running well with a static advance of 12 degrees and a full advance of 31 degrees at 3,800 rpm. All of our changes and the first and second running of the engine are included in the Bugeye Restoration Video Episode Sixty.

The exhaust was then removed along with the intake manifold, the HIF carb, and the exhaust header. This was done because we are sending the exhaust header to Jet-Hot for a ceramic coating. We have now covered the engine and pushed her to the side. The good news which is really too good to believe, and surely will not last, is that we have no oil leaks!

Wow, we started this engine work back in September of 2023. Considerable time has passed but we were continually diverted to work on other parts of the restoration. Other than coating the exhaust header we believe the engine is now complete. Hopefully, by Christmas she will be reunited with the car and it will be as easy as installing the engine and gearbox and taking the car for an initial run!
