Last week, I mentioned that I have developed the habit of
‘‘improving’’ the seat in the needle valve for my Strombergs
and got a couple of questions about how I do it. I fished
out an old needle valve and seat and went through the steps,
taking photos.
It was a used valve, one from before I started to ‘‘improve’’
the seat, and I was surprised at how rough the seat felt
when I started spinning the drill bit as opposed to
afterwards. Because these parts are pretty simple and are
mass produced, they’re left rougher than they could be and
that roughness affects the valve’s ability to seal properly.
See photos.
Nice tip and pics, thanks Pete!On Fri, Jun 7, 2013 at 2:39 PM, Jaguarpete jaguarpete@aol.com wrote:
