Phew 

that means it’ll be done by the morning. 
or is that just shoe making ?

[michaeljf]

Hello Hamish, I'm a little worried as around here they are a bit naughty. Regards, Michael.

Generally my view is 90% of something is better than 100% of nothing so with you there Michael.

Hello All

             I agree when I built my 1938 Velocette 500cc MSS from part bike etc I had not got a set of front forks but I accuired a set of Norton ones(same manufurer but different spec)

I used to get lots of people saying you have got the wrong forks in your bike but my answer was I know but I am riding mine where is yours and usual answer was still trying to find the right parts!!!

I did find a set later at a price I could afford and sold the Norton one for a profit

Very nice bikes there Michael. Glad you are riding them..

Hello Nick, I know, any excuse, oh well.(at least a legitimate one). The CV's were going to be long winded and time consuming and it's all taking far far too long, plus those Good parts are a joy to behold

Absolutely. Can relate. The hubs are the most important safety-wise.

Fixed it for you

Hello, I know e bloke like that, Had the bike for 26 years that I know of ..and still waiting for the right parts. Me,I have been riding my Matchless G80S for longer without "the right bits".  Hamish, see as soon as I took my eyes off them they snuck off fishing! Regards, Michael.

Can’t blame them for a bit of R and R

they’d be happier fly fishing for grayling this time of year tho

your elves not as bad as some!

[Nick Jones]

Ooo-er….. , wetting the Mogwsi is very bad……. but what EVER you do, don’t feed it after midnight!

That particular admonishment always bothered me. Unless you NEVER feed it then it will always be after midnight

[Nick Jones]

Yeah…… but…… Hollywood

Hello, They are certainly mischievous. Regards, Michael.

Hello, Back to the task. It's like Christmas, the bits to help finish the exhaust. I had ordered the parts over six weeks ago but no show so got a refund from paypal, but the worst part was the time delay. A re-order from an almost local and 4 days later like Christmas! (and he had to make one of the parts!) Regards, Michael.    AND I HOPE YOUR CHRISTMASES TURN OUT LIKE YOU WANT THEM.

[Hamish]

Nice

i wondered if my system would benefit from a flexi section as it is very rigid.

happy Christmas. 

[Nick Jones]

Yeah….. it’s on my to-do list for the Vitesse, mainly to try and stop the 3-1 collector moving about and leaking.

[michaeljf]

Hello, My son insists it MUST be part of the system! The green 3A that I crew for has one and we don't have any problems. Regards, Michael.

[michaeljf]

Hello, Bit of peace and quiet after Christmas and I have the other trailing arm back so... A check for cracks and guess what. But on the INSIDE on this one! So will tap and thread for the 3/8"studs then off to be welded. Regards, Michael.

[michaeljf]

Hello, Can't get out to do some of the jobs I need to at the moment! Also waiting for a couple of tools to arrive so doing little odds and ends. Regards, Michael.

[michaeljf]

Hello, Waiting for the 3/8"unc taps and dye to arrive to upgrade the trailing arm studs. New ones are 3/8"unc both ends and the l/h one (already done) is 3/8"unc alloy trailing arm fitting and 3/8"unf hub/brake back plate side. I have drilled the back plates (might have got a bit carried away with the drilling there!) In the previous pictures. Regards, Michael.

[Nick Jones]

Did see that the tin-pecker had been at you backplates. Was wondering whether ventilation or lightening…..?

Will your final studs be UNC both ends or just the trailing arm end?

[michaeljf]

Hello Nick, A bit of both but ventilation mainly. The side already done is unc trailing arm and unf hub end, the rhs will be unc both ends only because it's too hard to get unc/unf studs. The linings are competition ones the same as the green TR3 pictured elsewhere. Regards, Michael.

unc both ends

Just take extra care with the locking arrangements for the nuts as coarse threads are better (or worse!) at undoing themselves in service. Also provide less clamp for a given torque.

[michaeljf]

Hello Nick, Thank you for the warning. There is a container of "Locktite" waiting in the wings and the tension will be a bit more with the larger studs. Regards, Michael.

Good one with the Locktite.

Michael, the tension (force/area) stays roughly the same with the size of the stud/bolt. Generally 75% of yield for 'normal' steel bolts-nuts regardless of diameter (obviously less where one end is threaded into aluminium alloy). The torque goes up to get the same tension in the larger bolt. The clamping load goes up because the bolts get bigger. Using inserts in the alloy allows a larger tension in the bolt but will still be lower than a nut/bolt combo. Inserts in light alloy parts are standard aerospace practice and are not a bodge when done properly.

Hello, Well I finally got someone to answer the phone. I paid for some taps and a die (to do the trailing arm) on 5th of Jan. and they tell me the parts will be in THEIR shop in early Feb,! I shore picked the right name for this thread!! Regards, Michael.
