30s and 40s and 50s pipers and champs used a copper pitot tube. Right below it and soldered to the same tube was the static tube. The end of the static tube (impact air end) was soldered shut. Then many small holes were drilled at right angles to each other....
This set up works even in a slip. If these photos do not open Ill also post them in the photo section.

It would be relatively easy to make a 1/4" copper tube with a bunch of tiny holes in it and the impact end solderd shut and attach below the existing pitot tube on the Gull. Also a shorter run to the instruments.

I like that idea

I'd like to try this. I'm looking for a better static source.

Copper tubes undergo "brazing" in a furnace, with a thin application of some silver salt. a senior friend has two furnaces, for compressors and tubes that go into home appliances. is this solderd approach diy?

what's the inner diameter, positioning of these tiny holes? this description of a pitot tube so far does give a similar feel of a carburetor's jet.

I did my simple static tube by getting a new aluminum double one with the small hole one from Aircraft Spruce for about $15. Took out Mark’s for a spare and installed the new one and it’s shiny. Just tie wrapped another plastic tubing to the pitot tube back to the airspeed, altimeter, and VSI, I then added another one on the side to balance (in my simple mind) air.
