there is a piece of spring steel in the old VHS tapes, some have a plastic spring but mist have steel, Peter |

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: David D |
| 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: David D |
