Finally found out why rev counter on goldie wasn't working. P O had fitted an clock for clockwise drive instead of anti clock. Luckily, twenty years ago I converted a tacho for my big head Fury to clockwise, so, today converted that back and swapped clocks. I also learnt somthing else. I now need new glasses !

My work table is 1” plate, perfectly flat (using Moore & Wright machinery level); weighs 500kg. We used lasers for levelling.



Having visited Richards workshop a few weeks ago I'm not surprised at what he can do there, man, what I would do to have his workshop and expert's *loveit*
Richard, you forgot to say that the 1" steel plate bench weighs 1 1/2 tons  *yeah* *beer*

Hi Pete,
The work table is "only" 500 kg.
You will have the pleasure of meeting Robert in December; he is riding with us on "Orabandon 2019".

He is also making a new end plate for the magdyno on the 4G. The originals are made of cast iron and tend to crack; I have sourced three; all cracked. Rob will cast out of manganese bronze (I have plenty of scrap hydraulic pump thrust plates available).

See attached pics of the best cover I have (has been re-welded). Along side it is the plastic model that Rob has drawn (3D AutoCad) and printed (3D printer). He is now making the mold and then will cast , machine, and yippee.......!!

Can I just say that the engineering expertise out there is jaw-dropping. *eek*  In another life, I would have been an engineer. Just stunned at what people can fix, fabricate and improve. *wink2* *beer* *beer*  Well done fellas, much respect *ex* *respect* *respect*

How do you get around the shrinkage and adding enough metal for machining ?
The casting will be smaller than the object used for the pattern.

Hi Richard, Well it looked like 1 1/2 tons to me! You never cease to amaze me with what you do. Looking forward to the "Orabandon 2019" trip *beer*

Hi Roy,
Robert made his first furnace when he was an apprentice, and has spent the last 40 years in his back shed casting everything from mundane to intricate.

His next step is to make the molds, but I think he printed the model to compare it to the original (check dimensions). He has made the face that has been cracking a little thicker BTW.

OK Richard.
I was a patternmaker and was just passing on my knowledge of foundry practices.

When we were 15 Robert was fitting big bore (BSA) pistons into Lambretta scooters.

Years before that (late 60's) he converted his push bike to monoshock.

About the same time he caused a stir at school when he produced a cap gun which he had put a steel barrel and firing mechanism into, and converted to fire .22 shorts!
