Subject: [FlyRotary] oil return banjo
fitting?
Hey Chris,
That is what I need too. I can't even get a
banjo fitting on the home-brew mount I am making (if I actually use it). Made
to mount hole too close to the engine (20/20 hind sight). Was thinking
of cutting the head off of the mout bolt that is adjacent to the oil return
port and weld on a steel plate for a head, this may let me use a regular and
possibly stronger bolt.

Rusty,
You
were looking for a banjo fitting for the oil return line from the cooler. Here’s another option to avoid the
engine mount.
Take
a metric-to-AN fitting, M18x1.5 to AN-10 male and cut it in half. Drill out each half slightly and
insert a piece of 5/8” 4130 and braze.
Very strong, easy to get on and off, and avoids the engine mount (looks
close in this picture, but length of tube determines how much you’ll miss the
mount). 3.5” of tubing will work
well. You’d think it might break,
but if you have about ½” of the tube brazed inside each end (2.5” of exposed
tube), you’ll see this is strong and well supported from within the engine
threading. The 5/8” 4130 I used
was 0.62” wall thickness, leaving the interior at ½”, preserving the AN-10
flow rate. Took about an hour to
make.
