381380 TO Italian playe, Turin area. So Michelotti?

80psi in an inner tube tough enough? Cured superglue is rigid, you want flexibility.

Which explians the sooty plugs and poor running.

Graham, I'm sure you're right (I didn't get out my trig tables) but that would mean that the belt offered much less restraint on the person, to their detriment. Seat belts should as far as possible go straight back, horizontally and vertically, to the anchor point from the shoulder, to give as much restraint as possible. +/- 10 degrees is allowable (less than 0.2 if memory serves!)

Puncture mending kit from local bike shop?

Thanks, Graham! I can do physics. But arithmetic?? Bests John

That's because brass is a cheap and nasty substitute for what should be used!! Brass is too soft a metal. PROPER manifold nuts are BRONZE! Find a boat chandler's. John

You make a point that I studiously avoided! Yes, MASS stays the same under any acceleration, but WEIGHT varies with the local 'g'. In orbit, free-fall (or while falling off the Burj Khalifa - 18 seconds!) your weight is zero. When you hit the ground, it's another story. John PS You don't "Weigh" any number of newtons - it's a force, not a mass. PPS It's also an SI unit, and is therefore, like ohms, pascals, joules, watts, teslas, henrys, bequerels, seiverts, grays, etc, etc, spelt without a capital letter. Except for Celcius! Because they are degrees OF Celcius!

Ooooh! "Bits-left-over-after-rebuilding-grandfather-clock" syndrome! Never a good sign! The only single 'cam' in an OD gearbox that I can think of is the eccentric on the front of the main shaft, that drives the pump to pressurise the operation of the O/d, so if that's missing, then no pressure, no operation. My copy of the Official Workshop Manual has a test procedure for the pump, Page 2.305, "Functional Check". The usual exploded diagram of the O/d omits the "front of the main shaft" and this cam, but again the OWSM has pictures on pge2.307. Also, my Haynes manual for the Spitfire has a diagram that includes what looks like the part you show, No.1, "operating piston" meaning operating cam, I think. Scans below. JOhn

You trust your life to "old but good condition" seatbelts, johnny. Bye, bye, johnny. I did fit to new seat belts, in my Silverback. I'm still here. Force = Mass x acceleration. Stop in 1 second from 60 and that Force is 1890 newtons [60-0mph/1 second = 26.8224 m/s^2 70kgs x 27m/s^2 = 1890 newtons] The force of gravity is just under 10 newtons. So Instead of weighing 70 kgs (I wish), for a second I would weigh nearly 14000kgs. My seat belt/harness (and the rollcage) saved me. Buy new seat belts, please. John

Take your passport! As a student, I spent three months in Denmark. Scandi-tax on alcohol meant that for a night out with friends, we went on the ferry to Sweden. But unusually once, everyone had to disembark at the Swedish end - and I didn't have my passport. Why should I? I was arrested as an American draft dodger, escaping VietNam. Only my Danish friends got me released. John

Hence the name, I presume!

Thank you, Johnny! I always assumed the iron.oxide was magnetic! EDAScHD! John

Hmmmmmmmmmm! Seat belts "that have been on the shelf for years"? Like, forty years minimum? Trust your life to those? Unless you want them for a purely show car, please buy new! We can't afford to lose Triumpheroes! It is generally accepted that the life span of a seat belt is ten to fifteen years, whether they are used or not! If you do use OE belts, as a minimum, please replace the webbing straps. Lots of outfits have the equipment to do this. John

Clean and wire wool the rusted areas, then treat with phosphoric acid. This leaves a hard, insoluble layer of phosphate on the surface where any remaining rust was, better than a coat of paint! A magnet will catch any remaining rust particles, and tiny wear particles - good practice anyway. But not loose, sump plug with bonded in magnet best. John
