    Self Clinching Studs

    Its hard to find 10-32 panel mount studs (like clickbonds) in lengths of 3/4" or 1". Often they are $2 or more per piece. I have a bag of 1/2" long clickbonds that I got from JD at Infinity Aerospace, but these are too short to reach through the firewall (they are good for surface mounting but View the full article

    Ideas please

    Cozy Mark IV, IO-360, Lightspeed one side, Bendix on other side, fuel injection. I have a persistent “glitch” that manifests itself as a “cough" at altitude and speed.

    Tony Bingelis Books

    These were mentioned recently and I happen to have duplicates of both: Tony Bingelis on Engines and Firewall Forward. I’ll happily send them to whoever would like them for the cost of postage. Figure USPS Priority Flat Rate Medium box at $14.35, or media rate for much less but much slower. View the full article

    Engine Mount Hard Points

    In my switch the Lyc, I need a new engine mount which I ordered from Cozy Girrls. But the lower two hard points were drilled to 7/16 for the old engine mount rather than the plans 3/8. Also they are 27.75 apart rather than 28.0. So I'm thinking to fill the holes with JB Weld and redrill to 3/8 View the full article

    Some of you asked what caused my nose gear collapse this summer on my way home from Oshkosh. My Mkng-6 failed enclosed is pictures. Since the incident I have had little desire to work on the plane today I had some free time so I removed it from the plane. It is time to start fixing the plane. View the full article

    Main wing spar

    Some of you say that chapter 14 ends up being not so hard. Maybe, but not yet. Okay. Page 14-2 paragraph 2. Last two sentences. It starts out with "Note that the top" and the second sentence ends as "full span" okay that has to be back words. I am past that, but. Figure 7 on same page. View the full article
