I've been a little distracted recently, too much going on! In this video, I fix a problem with the non-return vale sticking!

Something wierd happening with the sound, looks out of sync and slow!!

All the best, Matthew

Good progress Matthew  :thumbup:

In the good old days, motor cycle oil pressure relief valves were just a ball bearing pressed by a spring against a cast iron bored hole. The received wisdom (written into maintenance handbooks) was to put a bronze drift against the ball, and give it a firm clout with a hammer, thus deforming the seat to the sphericallity of the ball. Those of us without bronze drifts used a steel rod, then replaced the ball bearing with another identical one, and it seemed to work splendidly. (no lapping allowed as the oil galleries would become contaminated)

mattinker:
Well, I wasn't sure whether it was the seat or the walls of the valve hanging things up, this way I was able to cove both!

More adventures to come!

regards, Matthew

Here is a short video on making a gasket for the Warco hacksaw, more to come on getting the saw going. it's kind od an oldtimers trick!
