The end is nigh! One more day and this will be done. I drew and 3D printed a windshield wiper for the front window. It's draining now on the printer and I'll install it during the next session. It's very delicate so I printed 12 of them thinking that I be able to cut at least one of them from the supports without wrecking it. I attached what appear to be ram air turbines that hang off the engine housing. This was another case of very fine styrene moldings breaking in the sprue before even getting a chance to remove it. The solution: more tiny drilling and wiring. During the assembly process one of them broke in the middle of the shaft and that too got the wiring trick.
To print tiny parts I draw them on a stick and draw my own supports. The supports function in the slicer is light a sledge hammer to small stuff like this. They printed succssfully on the new printer. There's still the challenge of getting them off the stick without breaking.
Here's the ram air things broken on the sprue.
And here's the parts repaired including the additional fracture in the center of the shaft. 0.015" phos-bronze wire is used to make the joint.
Here they are on the model along with the engine door supports. I was going to make those out of metal too, but they didn't break and I got them installed okay, so I set aside the scratch-build plan. They both need to be painted… tomorrow.
I attached the remaining subassemblies including the main rotor hub, Long Bow antenna and tail rotor. I decided to install them now and not bring them as pieces to be installed on site. I will protect the model so nothing will happen to them (Famous last words).
And then there was none. I went through all the remaining sprues and any parts still remaining are either for different AH-64 versions, options for this model or parts that were replaced or ignored. It's good to see this...
With the addition of the missing wiper, painting both wipers and the parts insalled today, the model will be DONE.
