Small compression ignition engines can be difficult to start, an electric starter motor would make life easier. I still have the scars from the one I had over 50 years ago.

Thirty something years ago we were camping on a site by Chesil beach. It was a clear but moonless night around two in the morn and black as your hat when I unzipped the tent flap to visit the site toilet. What I saw near took my breath away. I have never seen so many stars in the sky before or since. I saw two shooting stars before I had even reached the lav - an unforgettable memory! (the stars - not the lav) cheeky

Rik

Light pollution makes it difficult to see the night sky, mountains are probably the best place to view, if you haven't seen it before you will be amazed at the number of stars in the sky.

Thread: Red fibre gasket material

If you have a bit of old circuit board with a section with no holes, strip off any copper, and there you go, old boards tend to be larger, with larger areas without components.

Ian S C

This reminded me, when I first started assembling printed circuit boards they were made out of Paxolin (SRBP), after a few years the manufacturers changed to glass fibre sheet. Dave.

It is called Red Fibreboard, appears to be made of compressed, chemically treated felt. I have some thick stuff, how much do you need?

Thread: Alba 1A Shaper.

I remember the rows of used, and seemingly unwanted, shapers. They always had quite a few Boxford models in stock.

When the UK schools curriculum dropped all forms of practical work and disposed of their metalworking equipment there were thousands of shapers on the market, many of which had never been used. It was difficult to GIVE the things away. There has been a resurgence of interest in recent years. I blame ill considered articles in MEW for the current high prices.

My Alba shaper had both horizontal and vertical feeds, I believe the vertical feed was an optional extra. The only thing this model lacked was the table support, which isn't a problem if depth of cut is reasonable.

Thread: What did you do Today 2018

Thank you all for socks/trousers putter onner info.

Any of you with bad backs, if you are not already aware, the problem will not go away. While you are fit enough to move about, get youself some walking sticks, crutches, a Zimmer frame and whatever else you need for minimum mobility BEFORE you need it. If you leave it until your back packs up, you get in a NHS Catch 22 situation where you have to go somewhere to be assessed. NOT useful at all if you need crutches (which you haven't got) to go and get crutches. You may not think it important until you actually have a problem but a week or more without sleep will definitely change your mind. You will be fortunate indeed to get any effective pain relief without visiting your GP, which you will not be able to do without some mobility aids.

Ady1, here in NZ, and I presume in UK, you can get through your chemist shop a devise for putting socks on without having to bend over. You just thread the sock on the end, hang onto the handles, poke your toes in the end of the sock and pull.

Ian S C

I suspected such a thing may exist, I've asked in chemist shops with no luck, when I say I need it to stop me bending over their eyebrows go up. I wear slip on shoes but they are sometimes difficult to find, I suppose that's the vaguaries of fashion. I had a notion that an adaption of the hot dip wax used for coating new and resharpened cutters might be useful, might keep my toenails nice and sharp if nothing else. Dave W, yes, I've spent many miserable hours on the floor, nothing like dragging yourself along by your fingertips to make you appreciate the simple things. Amazing how many large spiders pop in to say hello when you're stuck on the deck, hairy buggers are just flaunting all their legs.

Dave

Ady1, I know what you mean about getting socks on. When my back plays up, I have a sockless week (or month) depending on how bad it is. Sometimes it has to be a trouserless week, I don't go out much when it's that bad!

13/05/2018 18:42:36

Michael, thanks for the Grey Flash links. Very pretty too! I could almost forgive them for only being half a bike.

A replica Grey Flash would be nice

The engine has one cylinder missing, how about a Norton engine in a Vincent frame?

Thread: Myford gearbox question
05/05/2018 20:58:03

Mark, your post crossed with mine, glad you sorted the problem. I've had leadscrew handwheels on all my lathes, I turn the leadscrew by hand whilst moving the gearbox levers, probably kinder to the machine than trying to engage the gears while it's running.

05/05/2018 20:53:10

You would have had to take the top off the gearbox to fit it. On the underside of the gearbox ABC lever there is a quadrant, a bronze slipper fits onto this, the oblong part engages in a slot in a sliding gear. It sounds as if the slipper is either not engaged with the sliding gear of it has fallen off. It needs to be supported with a finger and guided into position when refitting the top of the gearbox.

looking at the tip you show I'll bet it's a two sided tip, 3 edges ea. on top & bottom.

​George.

Indeed it is! I have a Myford holder to fit the patent rocking shoe. The tips are straight edged, they sit at an angle in the holder to provide front relief.

Back in the early '70s one of our club members had a Vincent and I used to drool over it.
Fast forward a couple of weeks and he turned up on a Honda CB400 ?
When I asked him what happened to the Vincent he replied that with an electric start he could spend more time enjoying riding it than starting it.
DaveD

The Lucas magneto didn't do the bike any favours and you really didn't want to spent too long kicking the thing over. The differnce is that they are now worth enough to spend the money to sort them out, but if you want it to be completely original, that's another thing altogether.

Thread: Machine painting
07/04/2018 21:26:56

If the background paint is dry the job can be done by hand with an artists brush, any overpainting can be cleaned off immediately with a cotton bud moistened with white spirit. You need a steady hand for this, a hand rest can help, signwriters use them, just a stick with some padding on the end.

Nice paint job!

--but it was compounded by the cockpit hierarchy which gave the captain rigid control with the first officer and other crew discouraged from attempting to challenge him.

Had there been freer atmosphere in the cockpit, the accident may well not have happened--

That's rubbish, nothing ever stops a decent junior officer from ever challenging a superior officer

I over ruled a captain on at least one occasion, the poor guy just couldn't handle it but most of the time he was more than capable and more capable than me

It all boils down to the individual and the situation

The co-pilot of a BAC111 failed to challenge his captain when the aircraft entered a deep stall after take off and crashed near Runnymede with the loss of all passengers and crew.

Avilable from car paint suppliers and shops in aerosol cans, works OK but use a filter mask, disgusting stuff to breathe!
