F-89F Advanced Scorpion

Working on the spine.

 

I spent time designing the spine of the aircraft. In Fusion 360 I designed a one piece spine that goes from the rear of the second cockpit to the end of the tail. This was too tall for my printer, about 10 inches long. So I cut it into 3 pieces.

 

Here they are.

And dry fitted onto the model.

Looks good, smooth curves from front to rear and straight as an arrow. Starting to really like this 3D stuff.

I have been working on getting all seams filled and the entire fuselage sanded and primed.

 

As you can see I am not done yet. This is the second go around, at least one more to go. I have spent considerable time working on the aft fuselage.I have blended 3d parts, plastic sheet and loads o Bondo to get this result. Not there yet.

Here is the basic horizontal tail, still lots o work to be done.

And last I am working on the windscreen. These can be difficult to work on due to the limited gluing surfaces. So here is my solution, I have forced the actual windscreen into a custom cut "holder". The "holder" will then be glued onto the fuselage.

I have designed the exhaust ring for the mid-wing pods.

 

I did not know how to design a circular part like this until last night. I googled how to do this, watched a youtube video, and viola! Here it is.

I then cut it so that I could slip it onto the pod.

Dropped into place.

And glued into the channel. Sanded flush.

A little more 3d printing.

 

Working in Fusion 360 is a little bit hit or miss for me. You think you have it right....but no. Here are my 3 attempts. First one is too small. Second one has holes for the rockets that are too small. Finally something that I can use.

Amazing, I really enjoy you creating superb models from almost nothing.

Wow.  That is coming along nicely Dan.  I really love all your builds.

Looks like a challenge, Dan!

Thanks guys. I seem to gravitate to scratch builds over mainstream models these days. They may be more challenging, maybe. But they are definitely more fun.
