• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction).

Haven't posted anything major in awhile, so I thought I'd show my Saturday afternoon project....A pitot tube and a static port


Start with a spare chunk of 6061-T6 square bar scrap from the scrap box...See Mom? That's why I never threw away anything!! :)

True two sides with face mill. This gives you a good surface to use as a straight reference. Then hog it out until you have this:

I put a 60deg bevel on the edges. Then drill a hole for a 1/2" tap on the top, and a hole for a 3/8" NPT tap in the side and thread, like so:

Then I used a piece of tubing, 6061T6, 1/2" diam .120 wall.I put a 45deg taper on one end, threaded the other end, and polished it. Screw it in and you have this:

Overall length: 17.5"


While I was there, I decided to cut a static port for my fuse. This picture does not show it completed. I have to chuck it in the rotary table on the mill and drill the four mounting holes....but here is what is done so far. It will mount from the inside using flush mount rivets:
