Station 3 and 5

Station 5 was drilled to accept the fitting today. The drill jig came in really handy.

Here's the fitting in place with the AN3 bolts.

While I had the drilling jig handy, I drilled the engine bearer support brackets too.

The Hisso engine utilizes a completely different Station 3 cross member. The OX-5 versions have a really pretty hoop to span the longerons above the accessory section of the engine. The Hisso cross member angles down (where it attaches to the wooden mount) across the span, and back up to the other side. It also curves to stay out of the way of the fuel pump. So...the tube angles down, curves and angles back. Not easy to build. So, I decided to build the tube straight and weld in the curve. Here, you can see the straight tube cut out and the curved piece in it's place.

Here's the finished tube with the curve welded together. It was much easier than wrestling with a tubing bender while trying to keep everything straight.

Remember the U-bolts I made recently? They are being heat-treated right now so I decided to make the brackets that hold the U-bolts in place. I cut some 1 in. .090 square tubing until the "ears" were 3/16 high.

Here they are.

The ends were ground on the grinder and hand filed smooth. You'll see where these pieces go soon. I have to drill the holes for the U-bolts next.

Enough for one day - on a lighter note, I received some pictures from Milt Clary of Vienna Virginia. Milt e-mailed me a few weeks ago asking questions about the Jenny landing gear. He had decided to build a scale "mini" Jenny to help his church advertise Vacation Bible School in an upcoming 4th of July parade. Milt and his crew really did a great job! Check out this Jenny!

Milt decided that a Jenny "was such a historically significant airplane and intriguing to kids", He thought it was the perfect airplane for the program. Anyone interested in seeing this "mini" Jenny come to life, check out

Till next time
