F-4E; Yoav Hozmi model

[Isaac]

While working the canopy, I started a quick research as to what externals do I want on this model.

I am leaning toward conventional gravity bombs ( M117 and Mk-82 ) types.


examples here:









I'll probably build a few configurations before I decide what to attach.

I am working the canopy now. So far, I made 6 of them and all are 100% crap!!!

Not sure what I'm doing wrong. I will try again.

So I tried again. Managed to get one good one.


I cut the rear of the plaster mold to reduce the size. That helped. However, still getting folds and creases. Experimanting now. Also I'm using plastic sheets of 0.010


Pics soon

The plastic sheet has sagged so much that I had to pull it out of the oven. May have been too warm?

This entire process is an art form that I have not mastered. It takes me sometimes 5-10 tries to get one canopy. Expensive deal!!!!!!!!!!!!!!

here are the canopy parts.





Assembled. I printed a second set for this purpose. The better one will be used for the frames over the vacuformed canopy.





and general fit to the model





This will serve as the basis for making a plaster molds. So this is not the actual canopy parts to be used.

Now its time to make the mold.


I used the canopy itself with internal sections to form it.




Next is the Plaster of Paris





Pour into the mold, add the wood base





Now its dry. Remove the paper





Here is the outcome. Not happy, needs repairs




I used Bondo and then sand to shape.





Ready for the next step ( Vacuforming )

Hey Issac,
Don't forget the rearview mirror



My 17 year-old loves this airplane and my plan is to make this model for him for X-Mas.
Thanks for this post and thanks to Yoav!
