Write your longer posts in notepad, save it and then paste it in. Its happened to me before and annoying so that's what I do now.

When I write a long post I usually open a new tab on the forum and then copy and paste it into that before posting .. to avoid losing it through timing-out.

Work in progress on the oil breather catch tank/chain oiler reservoir.

350TSS · 28-07-2017, 06:47 AM

The plan was to cut the shape of the two sides in 1mm aluminium and then cut the shape of the central portion which has a variable width to enable it to be inserted into place. The tabs included on the side pieces would then be joggled so the central portion was effectively flush with the side pieces. This plan was formulated before I had a good look at my joggler, which requires a tab of at least 12mm to work. I do not have 2 x 12mm to play with (the finished article will vary in width between 10mm and 40mm). I now have to devise a method of rebating the tabs close to the bend by 1mm. The joggler I have has removable jaws so maybe I just make some new jaws that will enable the rebate within 1 to 2mm of the bend????

Thanks for the advice re posting, I was losing the will to continue after composing my last few posts and then finding them missing when I pressed "reply"

I spent Friday trying to modify my joggler jaws. I did not have any 6mm steel plate so I had to cut 4 x 3mm plates to make 2 x 6mm plates then weld them together. I then filed them with the crease about 2mm from the front face. Getting the crease line square to the front and parallel with each other was a challenge, but more so keeping the surfaces flat and parallel. Just about managed it but with probably a 0.005" bow in the surface. What I did not realise before I attempted it how important the geometry of the arrangement was. Moving the crease line further away from the pivot meant that the jaws would not work properly if they were parallel when clamped shut, they had to be parallel when clamped shut with a 1mm sheet between the jaws.

Another problem I did not think about was that moving the crease away from the pivot caused it to cross the hole for the retaining screw at the front. This meant that the resulting "joggle" on a test piece of aluminium had an 8mm gap. This is not the end of the world but annoying nonetheless.

The photos look as though the results would be very shabby but I think that is as a result of my heavy handed welding of the ends of the jaws. The crease line obtained on a test piece is straight and uniform, albeit with an 8mm gap in the middle of each joggle. It just means I have to go over the gap with a second joggle.

ok, 16 pages read. I'm up to date! Absolutely loving your work so far, what a joy to read. Very inspiring and ingenious ideas.

Been on my hols to visit my mate in the South of France. He just turned 70 this August and still races a 500 Manx in the French classic racing championship and despite being 6' 4" and 94 kg he still gets regular podiums. He donated a set of coils to me which I shall probably try and use as they are considerably lighter than the standard set up and more importantly occupy a smaller space.

The existing monster ignition system uses I pick up and two coils but each coil must fire every turn of the crank as the pick up is on the crankshaft. i.e a wasted spark on each cylinder every turn of the crank. At 9000 rpm the system is therefore delivering 36000 sparks per minute.
The Manx Norton would normally be fitted with a magneto running at half engine speed so at 9000 rpm it would be firing 4500 times per minute but this one is twin plug so 9000 sparks per minute.
We shall see if it works

I am not really happy with the finished article, it does not hang from its mount at the correct angle and with all the easiweld rod employed it is actually a bit too heavy. I think I will make a mould for a carbon fibre one.

Not sure how much of an advantage there is but there's a guy in New Zealand makes an ignition pickup system that fits to the layshaft for the cam drive which runs at half engine speed, so no more wasted spark. Also, being external it is easier to adjust as you don't have to remove the LHS crankcase cover.
