More work has been done,
the exhaust box was glued into place together with the firewall.
The rectangular edges of the back plate of that box need to be shaped to the side bottom covers later on.

Due to a room in our house that is refurbished all is a bit slower though...
The tail wheel shaft hole needed preparation.
Now the drawing is studied again to turn and mill the tail wheel.

...The tail wheel shaft was made to fit the fuselage. The other parts will be made soon too.
Now the hole can be drilled to install it.
Also the engine was taken apart so I can make the arrangements to make it fit the cowl.
Must be as narrow as possible. That is why I will install the elbow to turn the carburetor 90°.
This way the air will be taken out of the fuselage. Doing so the carburetor settings must be much lower than the original settings which means less fuel to fly!!! Also a new exhaust will be made to fit the exhaust hatch.
Due to the room, less time then I wanted to build the model...

Due to work in the house less time ....
However the engine was stripped so that the carburetor elbow could be modified.
Also a new insulation piece was made so that the Original one is now obsolete.
Using this one would bend the trumpet up high.
I want it to be as far backwards and as low as possible.
To be able to do this the back plate of the starter needs some reworking as well.
The carburetor insulation piece is ready too.
Tomorrow the carburetor will get new controlling arms and springs.

...more...
See also the little help on the Myford, two damaged sliding calpers are now my digital help.
Had seen this before in the workshop of another modeler. Copy paste...;-)
Works fine, the depth measure stick is clamped with a strong spring.
On the diameter you need to devide all by 2... :?

The exhaust parts are cut from old oil filters, paint was burned off before grinding all clean, the centre pieces was drilled by 8 mm, and fits the middle of both chambers.

...and more...
The longer prop hub was screwed on, the base plate was tested with the carburetor and a small piece was ground off.
The new distance pieces where turned and screwed on.
Now the starter must be back on with the new arms to control the choke and throttle.
