Auster mk5

we have this.



supposed to go in here.



fits but..................................................





it might be too small.

Very nice, but aren't the cylinders supposed to be at the same level as the prop shaft?

they are, just about.
might have to scrap the whole thing and start again. maybe
or i could just leave it as is and do something else.

Looks great Tony I think you should leave them as they are

well i added a bit of detail to the undersize engine.




i suppose i will have to start the main wing center section soon.

First of the wing ribs cut out.


need to cut out the ribs where the ailerons go next.
then sort out the flap cut outs.

cut a ply center section rib as well, need 4 of these so i can sandwich the uprights between them.

NOPE, twas a naca section, naca 23012, if i remember rightly curved somewhat on both sides

All Austers used it except the Agricola
It looked like this just as Tony has it.

well i have cut 4 ply wing ribs for the fixed center section today.
so my next job is to make up the wing mountings and main wire work.

then i can finish cutting ribs and start laying out the wings.

i think i will just draw up a simple plan for each wing, just showing spar and wing tube positions and work out the rest on the fly.

We used to draw just one wing, then rub paraffin/diesel/kerosine over the plan to make it translucent, then build the other wing on the reverse.

i have got some 5mm piano wire for the main wing joiner and some 6mm brass tube that it slides nicely into.
so that's the main joiner sorted.
need some 3mm and tube for the rear joiner next.
once i got these bits sorted i can make up the center section and then use it to line up the tubes when i construct the wings.
fun bit will be making up all the wire braces in the fuselage.

While waiting for hurricane tails to set i tackled the auster main wing center section.

four 3mm ply ribs and 2 bits of 5mm offcuts of wire and some 6mm balsa later.



the wire sits on top of the spruce uprights to set the incidence.





The plan is to fill in between each pair of ribs with 6mm balsa and then once i have run the wing mount rods through, glue the whole lot in place with epoxy.
i can set the width of the cabin top then as well.
the wings will have tubes set into the first 3 ribs each side to accept the wire.
will have to make up some mounts to lock them onto the center section and then finish all the glazing wires off.
