      Hi Robin
      1) Will you have enough clearance for the wiring for the ignition switch, push start button and handbrake cable in that location , as surely the prop shaft is running very close to them?

      2) I note that the reverse light switch has yet to be installed in the gearbox , have you also sufficient clearance there to fit in situ?

      3) In the early 80's I helped build a Westfield SE with a Lotus Twincam. We also used an indicator switch like that. They were used on the early London Black Taxis and also milkfloats and were on a timed release.
      It is a good move as the Marina /Mini stalks don't always self cancel and in bright sunlight it is difficult to see the "tell tale" green dash light flashing.
      At least you have avoided that issue.

        All comments greatfully recieved
        Ignition switch is quite short. ATM it looks like there is clearance! Handbrake cable is nowhere near...
        I am not bothering with a reversing light. I checked and it's not a legal requirement it seems.
        Cheers Robin

          With regards to the reversing light, I wired mine up and have found it extremely useful for when I reverse into my unlit garage, after a drive. Obviously our requirements /circumstances may be different, but at least something to consider

            I have just about completed the wiring loom now. All I need is the engine and a few lights to connect up!
            I have confined a lot of the spaggetti to the dashboard.

            The little button (temporarily) mounted on the steering wheel is actually a wireless horn button. The receiver is amongst the stuff on the rear of the dashboard. The plan is to bodge it around so that it sits behind the steering wheel central horn push.

            And a few more pictures of the rest of the wiring waiting to be connected up. All i need is the engine now!

            I have managed to keep the high current (starter motor) wiring nice and short. (Red)
            Not sure what route I am going to use yet to reach the rear of the car but it is all contained within one cable. (Black)

              I have been working on the heater install the last few weeks. I bought a (fairly expensive) heater from T7Design as the basis. I don't think it represented good value for money! When i took it to bits to modify slightly I found it just comprised a computer style fan, albeit a powerful one, and a heater matrix in a simple aly box. It would have been considerably cheaper to make it myself. Ho hum - you live and learn.
              The heater has 4 outlets, I used 2 for the demister vents and the others for the footwells. I added a 5th, with a little flappy outlet thingy, that points directly into the interior. The heater is supposed to be 3.5kw (hmmm) so I hope it will keep things toasty.
              I replaced the heater front panel with one of my one which also serves to mount it and carries the on off switch, the above mentioned 5th vent and will also act as a mount for a 12 volt socket and the choke cable.
              At the moment the heater is just configured for re-circulation, but I have allowed enough space behind it to allow for some ducting to the outside world should it prove necessary. For the moment I considered this a complication too far.
              I recently discovered the Car Builder Solutions catalog and this has provided the heater hoses with right angle bends. Very handy.

                As a prelude to making the bonnet side panels I have been playing with ideas to mount the spare wheel. The intention is to side mount it on the passenger side as the car will mainly be driven with just the driver and this will help to balance out the weight a bit. I purchased a rather agricutural looking trailer spare wheel mount from Amazon to use as a starting point. It now looks like this.

                And (temporarily) mounted on the chassis rail.

                I have yet to decide on the final position as the exhaust will also exit on this side. But clamping it to the chassis showed is was good and sturdy - if still a bit agricultural lol.

                I have also test mounted the radiator. I acquired a new old stock rad from another Marlin owner. It's from a Vauxhall Chevette (Viva?) I understand. Originally the car had a heavier duty looking rad from a Morris 1800. On comparison it has more fins but doesn't have any more waterways than the Vauxhall rad so I hope the Vauxhall rad is going to be OK. It will be getting as big an electric fan as I can fit in. The original design hangs the rad on some brackets from the join between the bonnet sides and cowl. Or in the case of this car just wedged between the chassis rails.... This means that taking the bonnet sides off for any reason in the future will be a real pain. so I have made a couple of L brackets to mount it directly to tha chassis. Seems to be a better solution although it does mean drilling the chassis for some rivet nuts.

                That's all for now. Bonnet sides next!

                  If you're going cycle wings and don't want to have the spare on the rear tub I wouldn't bother with it at all, I think it would look much better without a spare on the side, but I know that's subjective...

                  The radiator mount looks nice and neat. Rather than drilling into the chassis I welded tabs on that I could bolt the radiator mount to, just a thought

                    I am a bit paranoid about carrying a spare, not convinced that the squirty tyre repair stuff works! And if if you have a puncture it's always at the most inconvenient time and place, raining, middle of the night and miles from home....
                    My theory with the rivnuts is that even if they allow water penetration and long term rusting of the chassis it will still well outlive me lol.

                    • Hmmm, issue always is that in drilling the chassis to fit rivnuts for your spare wheel bracket you are also introducing potential weakness. If it wasn't on the side of the main chassis spar, it wouldn't necessarily be an issue; but it is.

                      • The Roadster chassis is massively over engineered, the main rails being 100x50x3mm box section. A few small holes really won't make much difference.
                        Had it been one of the later Marlin designs, in which much of the chassis is constructed of lighter gauge folded steel, I agree it could be a problem. All IMHO of course :-)

                        • I have made the first of the two bonnet sides. A lot of carefull measuring involved as it is a big panel and didn't want to cock it up. The front and back edges are parallel but top and bottom are both set at an angle. The bottom to follow the chassis and the top to giving the bonnet a pleasing drop towards the front. The original panels were shot but useful as a double check.

                          The original bonnet side has a lot of folds at the edges not really necessary for strength. But I came to the conclusion that it's actually a clever part of the design - the folded edges are what you actually see which means the 'orrible cut edges are hidden. Which is just as well as the originals seem to have been cut out with a jigsaw with the edges left rough. All done for speed of course. Anyway I made the replacement exactly the same way (I did clean up the edges), the only difference being I riveted the ally angle that strengthens the top rather than nut and bolting it in place as per the original.

                          It would be an understatement to say I am pleased with the result :-)
                          Just the other side and the bonnet tops now...

                            • I have completed the other bonnet side. Took less than half the time of the first one!
                              The bad news though is that I trial fitted the old bonnet which I was going to use as a template to make the new one. It is an awful fit - in fact it doesn't really fit at all. So I am going to have to fettle that first before I can even consider using it as a template. Hmm

                              As a bit of an asside I have been doing some planning. I am considering using this steering wheel. It's an old Triumph (Herald?) steering wheel and is dished and has sprung spokes the idea being it does provide some protection in the event of a prang. What do people think?

                              And I have been thinking about the exhaust route. I was always going to have a side mounted silencer but I would like the actual output to be at the rear of the car - not by the passengers ear. It looks like I should be able to route it between the chassis and the rear nearside wheel. Again - what do people think?
