Quite a while ago I literaly stumbled over a booster at that yard where all good metal congregates before it goes to meet its maker.
It kept calling me "to take it home as it could come in handy"
It kept occuring to me that it was handy, but where? and then it came to me
With a gentle push the diaphram fits nice into the trucks booster can and I think with a trim it will be worth a test
What do you think?
So boyed with enthuasium again, I rushed to the lathe and made up this collet and soon had the end out of the control
And the other end to get at the valves
Now to clean it all up, locate a softer diaphram and test it
cheer rod
