I did most of my rough cuts with Harbor Freight MultiFunction tool, with
the soft metal cutting half moon blade, went through about 4 of them.
Did some touch up with cutoff wheel, but it throws a lot of dust and
debris. Finished with sander and 60 grit paper. Bob Leffler shows the
tool on his builders log. Main issue was to not use too much pressure
and not stay in one place or blade and fiberglass would get too hot,
smoking and dulling the blade. Multiple passes with lighter pressure
worked best.

I used different tools depending on the thickness. I put pieces of hack saw blade in an air saw, but they dull quickly so the pieces got changed out often. Used it on the windows. A Sawzall with coarse teeth also worked well but was hard to control. The best tool was a 4" angle grinder (mine came from Harbor Freight .... they're disposable) with the concrete grinder wheel. It creates a lot of dust so you need to wear a mask and use a fan to blow it away from you. I have a big door on my shop and just blew the dust outside. When using the grinder, keep it moving, taking 'swipes' at where you want to remove the FG. This was useful around the door openings and smoothing out some of the 'bumps'. Good luck!

Harbor freight air grinder and the Vans provided cutoff wheels. If you have a decent air compressor you'll get through it pretty quick, otherwise you are given numerous breaks while the air compressor tries to keep up with the air supply the grinder requires.
Once that is done 40, than 60, than 80 grit sandpaper trimming it to fit nicely.

I used a Dremel multi tool with the semi circular blades. I did go through a few blades as the teeth wore down quickly. I also used a Dremel tool with small cut off wheels. I went through a bunch but it worked surprisingly well.
What I was surprised at was how munch of the doors were removed to get the cabin to fit in the door openings.

Hey Patrick,
All of what the others have said about trimming fiberglass. Plus, I found that sheet metal shears work great for the thin fiberglass parts. I.e. door shells, trimming around windows, etc. No dust, no fuss, then just finese sanding.
Later, - Lew

I would make one suggestion to the air grinder method and that is to do all of your cutting for fiberglass and plexiglass with an inexpensive electric die grinder. This way you will not have to worry about the air grinder bogging down due to the compressor running low on air and then having to cycle through again. I picked up a Harbor Freight model for about $20 and it worked like a charm.

Most all the replies suggested tools from Harbor freight. Poor Patrick Pulis lives in Adelaide, South Australia ....... maybe he'll let us know if they have HF down under!!!! It reminded me just how much we rely on and use all the cheap, imported Chinese stuff .......

The downside to buying the Harbor Freight, or any brand other than the Fein Multimaster, is the blade selection that is important cutting fiberglass. Fein offers an expensive bi-metal cupped blade that lasts just about forever cutting fiberglass. They were $79 for one blade last time we bought one about 8 years ago,,,,but well worth the money because its lasted through the build of 2 Cozy MKIV's and has seen a bit of use on the RV-10 and is still going strong. The mounting system is different for each brand so it would not fit the HF model.

But, you can buy almost 10 HF blades for that price, and the HF price
for the tool is about 10% of the Fein. Of course we get what we pay for
and less.

Patrick,
I used a diamond saw blade in a jigsaw for the initial cut then sanded down close with a belt sander. Finally finishing with a hand block sander. I tried a bunch of stuff but if I were to do it again I would stick to these three.

Yes, I'd second that thought assuming you meant by "diamond saw blade"
an abrasive type blade. They last a long time on FG and cut well.

Many thanks to you all for the advice regarding trimming the cabin top. Robin, I loved your idea the most for expediency!
It was definitely a white Christmas here in Australia last night, wow, talk about dust. I now know why people call this and the door sections, fibreglass purgatory!
I wish you all a very safe and Merry Christmas and most prosperous building new year for those of you who are still building. Those that are flying, I wish you safe and smooth skies.
It sounds as though there is a 'Harbour Freight' franchise opportunity waiting here for the taking down under!
Regards and many thanks
Pat in Oz
