Finishing Jobs

 
I’m now at a stage in the build where the rest of the work can be described as “Finishing”. Things like grilles, inner wings, sealing up gaps etc.

Having finished the wiring except for the fuel inertia cut-off switch, there was nothing for it but to concentrate on the bonnet; planish the bulge and fabricate a radiator grille and a grille for the air to exit. The bulge would have needed no planishing, having been smoothed on the English wheel had I not in a moment of madness attacked it with a bossing hammer to try to get more of a bulge after it had been fitted. What a crazy thing to do. The problem now is that I cannot reach all of it because my arm is not long enough to hold the dolly underneath while using the spoon with the other hand. Sadly I shall have to resort to filler for the parts I cannot reach. Anyway, I’ve mad a start on the bits I can reach and it is looking better. I have to do it in short bursts as I find it boring as well as tiring. No stamina these days!
   

The Grilles

Air Exit
I’m planning to make four grilles comprising radiator, air exit and a pair on each side of the bonnet for exhaust cooling and air inlet. I have had plenty of time to think about the designs of each and now I have a fairly clear idea of what I would like to achieve. In some cases, when the execution leaves a bit to be desired, the dream is better than the reality and that is a disappointment but one can only do one’s best.

Where the air exits the radiator on the Phoenix bonnet, to my mind it cries out for a bezel with a sunken mesh grille. The fibreglass moulding is there, just waiting for it.

I decided to make the bezel using the trusty hammerform technique and 1050A 16gauge pure aluminium sheet freshly annealed only where it was going to be formed. The hammerform was made from ply with the aluminium securely clamped in the sandwich.

The hammerform was made from ply with the aluminium securely clamped in the sandwich. I used a number of hardwood dollies and the finished result very pleasing. I’ve now got to source some aluminium mesh to fit and tack-weld into the apertures anyway, so far, so good and still plenty of room for error both in the welding and shaping of the

mesh to fit.Note, must buy enough mesh for mark 1,2,3 etc! It turned out, that our local motor factors stocked the mesh 30 x 90cm by way of a boy racer’s accessory so I bought one, bright anodised unfortunately. As it turned out, there was no waste on the mesh and welding into the enclosure went reasonably well once the anodised layer had been removed. I note that the original idea of recessing the mesh fell by the wayside but the end result looks acceptable in my opinion. After a lot of thought and input from friends from the Locost site, I’ve decided to paint the grille matt black. In other parts of the car, black goes really well with the red so I’m hoping it will look good.
   

Radiator

I initially thought of making a radiator grille from stainless steel wire like the one on the Special which itself was a copy of the Caterham and this would have been perfectly adequate. However, I wanted to be a little more ambitious this time and I could visualise a grille made up of horizontal highly polished slats that would suit the Phoenix down to the ground . Three different materials came to mind; aluminium, brass and stainless steel. Both the aluminium and the brass would need surface treatment, anodising or chroming so stainless is the favourite providing I can form it. I’m going to give stainless a go and intend using 20 gauge material. Basically, the idea is to start with 40mm wide strip and fold it in the middle so that in section it is slightly wedge shaped.

There will be four or five horizontals supported and held apart by vertical stainless steel tube having M4 studding passing through it. It’s difficult to explain but a couple of pictures should do the trick. I’ve now made a start on the grille and managed to fold the 20 gauge stainless without too much trouble. My folder takes it to beyond a right angle and once the line has been broken, it will continue to bend along the fold line. I used the vice with soft jaws to finish folding. Using a 1mm thick cutting disc, I trimmed off one side leaving an 8mm return on the underside of the slat. Cue some pictures. The start is quite promising and I’ve now got to get some 4mm bore stainless tube to use as stand-offs.

That’s as far as I can go with that at the moment. Rather than just mount the grille in the aperture, I’ve decided to create an aluminium insert that will I hope enhance the grille and also to hide the raw edge of the fibreglass upstand. The design involves folding, shrinking, welding together and a final hammerform. I started with 60mm wide 105A 1.5mm thick material which I folded down the halfway mark into a right angle. Using the shrinker, I formed two of the corners. In comparison with the flange size, the corners were tight and this tended to bunch the material up as it shrunk. Using a magnesium hammer and the surface table I was able to form the metal back into itself. It was then that I decided that the job would be a whole lot easier if the aluminium were annealed. And so it was. From then on, the shrinking was far easier and controllable.

A trial fit to the bonnet aperture, looked quite promising.
