Scott Vacuum Engine......
PJW:
there is a piece of spring steel in the old VHS tapes, some have a plastic spring but mist have steel,
Peter
Stilldrillin:
Managed a few workshop minutes, this afternoon. :thumbup:
Assembled. Then realised, I'd forgotten the leaf spring! :Doh:
The little coil spring, saved the day.......
Gave it a flick....... And it stuttered into life!!.......
You know that supreme moment.
When the blood pressure goes sky high. And, all you want to do, is dance about, for joy. :ddb: :ddb: :ddb:
It's A RUNNER!!!! :D :D
At that precise moment, SOMEONE, was knocking on the door........ "Grandad"....... Didn't know what to do! I nearly burst!
I had a Little Helper, for the rest of the afternoon.......
I bet Steven Spielberg, never had such a helper.......
Love it!
David D
Kjelle:
Nice job!! Sounds like your little helper is a ray of sunshine, too!
Kjelle
Stilldrillin:
Thanks Kjelle.
She's a lovely, little bundle of happiness. Especially, around Grandad......
So much for the "wonderful" idea, of the original graphite valve, lubricating the piston and bore. No need for other lubrication! :smart:
The vacuum chamber condensation, turned to rust, overnight!
Another, fun d mental flaw? I seem to get a lot of them, in my rebuilds! Sheesh! :palm:
Anyone know, where I can source 35mm dia graphite in the UK. At sensible cost? :scratch:

Stilldrillin:
Showing the original "Poppin", shim valve arrangement. It's a bit vulnerable........
So, I made a temporary guide arrangement. Shim, loose on the actuating arm.........
No chance, so far, of a piece of graphite. :(
I thought this would do the job..... http://www.ebay.co.uk/itm/300839376964?_trksid=p2060778.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Until I ran the mouse over, to zoom. It's made of dried leafmold! :scratch:
Guess it will have to be a brass piston.
The stainless tube has arrived, to sleeve the cylinder. See last pic.
A piece of 8mm stainless plate is on it's way, for the port face.
Progressing. Slowly...... :thumbup:
