    No need to get fancy or add anything. On the door side, notch the end of a stringer to meet the
    tube and leave enough length to create a pressure fit, after which the fabric also helps hold
    it. On the...

  • Posted in thread: Mag switch plate on wing root on 06-23-2017 at 05:13 PM
    In looking at Barn Cub (Oct 1946) and some other J3 restoration photos, I see there's a
    different switch plate used between the J3 and the L-4. And the switch position would be a few
    inches apart betw...

    This is the from the L-4 Erection and Maintenance Instruction manual. Tinnermans on the
    fuselage side and #4 PK screws on the wing side. The original fairings were pretty thin
    material, and leave a ri...

    Wow, gorgeous. That's a butyrate dope finish, correct?

    FWIW, this is from the L-4 Parts Catalog. Diagram plus Parts list (Fig 20).

    Apparently there was a Model 840 wheel rated at 800 lbs. Then two versions of the Model 841
    wheel, one rated at 900 lbs and one at 950 lbs.

    Or you can go old school like the L-4s in WW2 and fashion a gasoline ferry tank from an old
    oxygen tank and rig it up to the overhead tubes :)

    The nut or nuts are not where you show the arrow, the rod inside the tube passes through both
    sides of the strut attach fitting. The nut(s) are on the other side of the fitting in the photo
    (front sid...

  • Posted in thread: L4 (J3) Compression strut (inside wing) on 06-13-2017 at 03:08 AM
    The rod in the tube extends past the spar through the other side of the strut attach fitting,
    where the end of the rod is threaded. I believe mine is original with two 5/16" nuts jammed on
    each end. T...

    This is an L-4 wing, from the bottom. There is the compression strut out there for the spars,
    and a round tube that is a spacer and/or stiffener between the front and rear strut fittings.
    It's a hollo...
