Cutting Windows
I have a PKM fuselage on the way and it appears that I have to cut the windows out. Never done this, so any pointers you all can share would be great.

Fiberglass?

Diamond tip dremel bit 7134 if you have those nice brain surgeon steady hands.

Hot xacto knife is probably the way to go though. (Walnut Hollow at Michaels)

I use this little gem....

https://www.micromark.com/Micro-Mak...gsaw-Scroll-Saw

....and cut CLOSE to the line, but not all the way to it. Then I use a combination of hand files and sanding blocks (220 grit) to sand/file TO the line. I find doing it this way I end up with very straight, consistent edges. Yes it is a slow process, but the end result is what I focus on.

Cutting the windows out of the fuse is not too bad. Cutting the clear windows to fit the fuselage,... holy crap I do NOT like that. Material is hard to work with and if you screw up, it is not an easy fix. So you have that to look forward to! LOL!

Enjoy!

Steve that is a sweet little tool. Will have to order one.

As for now I use a hot knife I bought at Hobby Lobby (Michaels also sells them). I cut close to the line then use sanding blocks to finish nice clean lines.
I have used this method on prepainted fuselages even and got nice results.

Good luck on your project.
OH, and please post pics!! Us scale nuts love pics

Jim,

1st method.. Do the windows look like they lay flush in the fuselage ie. is there a rebate in the window opening? If there is then ensure you leave enough of a rebate on the fuselage to stick/fix the cut window to... (fix in place with Masking Tape till the glue dries)

Use a ZAP canopy glue to fix rebated windows..

2nd method.. If there is no rebate (the fuz is moulded with just an outline that you cut the window to) you will probably need to cut the clear plastic window slightly smaller than the opening and us as 'S' shaped extruded rubber gasket.. OR you need to fabricate a rebate on the inside of the fuz and use the 1st method of fixing the clear plastic..

This is 1 supplier of the miniature rubber moulding...

follow on from DG post
First check with the full size, to see which method of fixing is used?
Method 3, Cut the hole, then the glass oversize, and fix with , small screw's, small nuts and bolts, or adhesive
Method 4, do not cut just paint out the window section, there is a miriad of colours out there
Method 5, use vinyl,you can then print all the window details on the vinyl, frame, sliding windows,ect
With modeling there is always a lot of differing ways of doing things, start simple and work your way up
