Bolts, Brakes and Bodywork

After getting the buggy out in the week I was quite in the mood to get working on it again, so we agreed we would get it out over the weekend and see where we had got too and what the next stage was.

Saturday rolled round and we dragged the buggy out, I popped up the shops to get a 1st few we needed, nuts, bolts, washers, brake light switch, fuel line, low pressure brake line. While i was out we got some assistance from a mate who turned up to see how the project was getting on and ended up staying about most of the weekend.

While I fitted up the brake light switch and lines, Simon replaced our test engine wires with proper cables and I gave the body-shell a quick pressure wash.

We checked the chasis over for things that we still needed to do and it appeared to be that time, so before fitting the shell again we thought “Oh what the hell, lets start the engine”, out came the fuel can and the jump leads, after a few tries it fired up with a nice rumble.

A little off the side please...

A little off the side please...

Once this had been done we where really in the mood. So we lifted the body back on and realised that the fiber glass wouldnt quite bolt down as we had forgotten to remove some body mounts designed for the beetle shell, this was nothing the angle grinder couldnt take care of in a few seconds, with that done the body went on and car really started to take shape again.

Seeing as we had fitted the low pressure side of the brake system we decided to add some fluid and see if they worked so we topped it up and bleed the system through. Low and behold the foot brake started to hold the car without the handbrake.

Given that we had wires and pipes in place we decided it was time to bolt the body back down, out came the nuts, bolts and washers and i got to work with the socket wrench.

Starting to take shape again

As the sun started to set I decided to get the steering column out and see what it looked like with it fitted up, after a bit of fiddling it went in and i bolted the dash support in place to hold it up.

Following the success we had on Saturday we got up Sunday morning with a renewed vigor and set to work again.

We found the brakes had gone spongy and after a quick look around we tightened up one of the nipples on the master cylinder as it had been leaking. After bleeding the air out again, we started connecting up the wiring loom. We had previously fitted this into the shell so it just needed plugging into the engine components and did a bit of tidying.

I went back up the shops and bought a battery for the project and some other bits and bobs and we started working on the wiring. We connected up the engine electrics to the wiring loom and checked it was all in the right places.

Then came another big moment when we released we had the wiring all in place to fire up the engine from the dash switches (well by dash switches i may mean wires hanging out). So we moved all the loose tools and sealed a length of spare fuel hose into the top of a plastic bottle, filled it up with some petrol and taped it to the bodywork.

We put a spare battery on the floor as something to rest on, then came the big moment, we flicked the coil switch and touched the wires together, tick, tick, tick, BROOOOM.  The engine fired up quite easily, all be it with a puff of blue smoke from one side.

With the engine running Simon jumped in, dipped the clutch and and popped the buggy into gear and slowly backed it off the drive. This is the 1st time the buggy has moved under its own power since we started the rebuild.  I have this on video and will post it as a seperate entry once i have sorted it out and uploaded it, at this point the camera ran out of batteries so there are no more pictures from todays work.

Having archived this by lunchtime we both had places we needed to go so we tidied up quickly and went out with big smiles on our faces.

Getting back to the project a few hours later we fitted up the rear lights are back on and connected to the loom, I mounted the volt reg in the boot and tidied up the engine electrics, we tested all the lights worked by connecting up there relevent wires in the front of the loom to the battery, we also accidentally tested the horn.

After so much time and effort, I got chance to fire up the buggy and move it around the drive, oh what a feeling.

We finished off the day by wiring up and testing the headlamps, there where a few more jobs we could have done but we have run out of wire terminals.

Post Winter Uncovering

Its been too long since we last did any work on the buggy, and a few people have asked about it. While we have been working on this a mate of mine has built a mk2 golf drag car, and another mate has build a street fighter bike, seeing these getting finished has really got me back in the mood to do some work on the buggy.

Buggy

Buggy

While my daily car was off to the garage to have some work done i decided to drag out the buggy and see how it was. Having been under a thin cover all Christmas i was happy to see the drain holes had done there jobs and that it looked to be in the same condition as we left it.

Firstly a quick recap on the few bits we did over christmas, we cleaned up the lights, labeled and rewired them, recieved a few parts and stuck them in the garage.

Anyway onto the few bits i actually did the other day, one of parts i ordered ages ago turned up last month and got chucked in the tool chest. The steering column has a rubber square in the linkage that was all cracked and old. 3 of the bolts came out with a lot of force and some penetrating oil, the last one required a bit of a heavy handed approach, nothing that 2 Min’s with the disk cutter couldn’t fix. Then in went the new one along with some new bolts.

Washer Bottle

I fitted the new earth strap to the rear chassis point as it arrived ages ago and got left in the draw. I also re fitted the windscreen washer pump and hoses and give it a quick test.
Then the rain started so the buggy was covered back over and left until the weekend.
Rain :(

Wiring loom in place

Before it started raining today we managed to get the wiring loom into place on the shell. This is quite comforting really because it means we’re pretty much back where we started. When we picked it up it was in about the state we’re at now, which means the repair stage is hopefully over (we still need to get the engine looked at).

We’ve pinned the loom in place by drilling holes and looping heavy duty cable ties through the shell.

I’ve also put a hole in each floor side for drainage as it’s going to be permanatly open topped.

Dashboard Design

Last night we spread the wiring loom out on the floor in the house. Then with a roll of masking tape, a pen and the wiring diagram we labled both ends of every wire.

We have also decided on the new layout for the dashboard; the old layout was a mess and looks like the dials and buttons have been chucked at the dash while blind folded.

Dashboard Design

New Dashboard Design

The dials/lights are as follows left to right:

  • Volts, Amps, Oil temp, Oil warning light, Oil Pressure, Revs, Speed, and Fuel
  • On the far right hand side is a clock, as well as a plague we’re going to have there.
  • Switches underneath are for main power, push button start, ignition, aux, hazard lights, headlights, dip/high-beam. All of these have a telltale light underneath them as well.

From this mockup I have just started work on a technical diagram of what needs cutting and where.

Day 12 – Gauges

Typical example of a gauge I have no way in hell of affording

I mentioned yesterday that we’d have to replace the gauges. As I’m rained in today, and Jons out at No-Rice, I thought I’d do some investigation into this. Before yesterday, I knew pretty much nothing about how automotive gauges and displays worked. Now; it’s like I’ve swallowed both and encyclopedia and a catalog on the things. They come in analog, digital, analog AND digital, there are so many options, and they range from a couple of quid to thousands of pounds!

There’s even a hundred ways of mounting the damn things. You can flush them in your dash, build them in pockets in your dash, build them in pockets on your dash, under your dash, in your wheel, on your pillars, on a bloody head up display! It’s mental. Read the rest of this entry »

Day 11 – Another productive day removing crap

Cleaned up steering wheel

I went to Body Tone today with Robin to get an estimate for repairs on his car, and while we were there asked for a guideline estimate for spray work on the shell of the buggy. They said under best circumstances, assuming no patching is needed, and that we present them with the panels, all sanded down, approximately £500 for a lime green finish. They can do one. For that money, we could rattle can it ourselves with plenty to spare!

Yesterday we brought the steering wheel back with us, and Jon polished it up with a Dremel and a polishing bit. Here’s a photo of it in place now. The leather still needs a re-trim, but he knows someone through No-Rice who can do that for us hopefully! He’s going to find out tomorrow at the next meet. Read the rest of this entry »

Day 10 – More stripping

Studdying the electrical diagram

A fairly productive day today. We removed the nose cone and fuel tank, mainly in order to assess the damage to the brake system, and check out the steering/suspension.
