10. Ariel Golden Arrow - The rebuild continues

On my last blog, you will recall that I had finally managed to fit the front wheel. Well it had to come off again! After studying the front brake backplate, I realised that there was an "A" plate that bolts to it, which is connected to the stay that stops the back plate rotating when you apply the brake. This "A" plate can only be fitted before the wheel is mounted in the forks, so there was no option but to take it all apart again.You can just see the top of the "A" frame sticking above the front forks in this picture. This "A" frame is one of the parts that had come back from the chrome platers, so it was the first bit of chrome to be fitted to the bike. Once fitted, the wheel was put back on again and this time I could add two more chrome parts, the front fork cover plates.

This set me off wondering what else I could fit to the bike ?
I decided to fit the two HT coils, which fit in a really difficult position, inside the front of the frame. Originally, when I stripped the bike,  they were fitted each with one large self tapping screw into a speed nut on the HT coil bracket and one nut and bolt, through the frame and into the bracket. The self tappers were obviously because your fingers just can't reach the outer coil fixing points. Well I decided to try anyway and fix them with new stainless nuts and bolts. This was so difficult that it took nearly two hours and a lot of swearing to achieve. But in the end they were in. Talk about "one step forwards and two steps back". I then decided to fit the support brackets for the dummy petrol tank. Guess what? Two of the brackets bolt through the frame ahead of the HT coils and the only way to reach them was to take the coils off again.

It was at this point that I decided that this was stupid and I needed to make an easy and secure way to get the coils on and off, as I was sure that sooner or later I would have to remove them again. So I removed the coils and looked at the fixing brackets. The answer as simple, my business already uses 6mm captive nuts, all I needed to do was file the holes in the brackets until the captive nuts snapped into place, the coils could then be held in place and the bolts passed through from the outside of the frame. The coils can now be removed and refitted as often as I like.

Now those dummy tank brackets. There are six in all, two on each side of the frame and two on top, near the headstock. In order to make sure that they were in exactly the right place and at the right angle, it was necessary to offer the dummy tank into place. With the the top two brackets just fitted with the bolts tight enough just to be able to turn them, I offered the dummy tank into place and then reached in through the tool box aperture and turned the top fixing brackets until they lined up with the brackets welded to the inside of the dummy tank. This turned out to be a good idea as the two welded brackets were not fixed at the same angles.

Then the four side brackets could be fitted, they mount very strangely. Each bracket has two tongues that protrude from the back. The two tongues pass through the large hole in the frame and into to matching slots cut in some round mounting washers that fit on the inside of the frame. In effect the bracket and the round mounting washer "sandwich"  the hole in the frame and secure the bracket whilst still allowing you a degree of rotation to line up with the threaded holes in the bottom of the dummy tank.


Well, all that's left to do now is put the dummy tank back on again and do the same trick. Tighten the side bracket fixing bolts just tight enough to enable me to turn them, offer the tank in place. Turn the brackets until I could pop some temporary bolts through the brackets into the tank and then remove the tank again and properly tighten the bracket fixing bolts. Then a final try in place for the dummy to tank to see how it fits and looks.
