There is a posting in the FAQ describing the thread method. I haven't tried it myself personally.

RE: removing hatches
 
I remove my hatches by scribing them out with the "back" edge of an exacto #11. It's slow going and very repetitious. It gets easier each time you do it though, but it's time consuming. I just scribe along the mould line (normally a groove) around the hatch. If you have replacement hatches why not use a dremel on very low rpm as not to soften and distort the area around where you're cutting; by generating too much heat. Since I use the existing hatches, i tend to scride more towards the outside edge of the moulded groove around the hatch; then i just have to build the opening smaller by gluing in strips of thin styerne and then add a flange (lip) for the hatch to rest on.

I wathced the thread technique video. Very similar to removing a winshield from a car, they sell a wire specifically for that job. I did it before but can't remember how thick/thin the wire was. I think carpet thread might work too.

I've been scribing hatches out since the late 70s (1/32 and 1/35th) and though it is easier, I still don't like doing it, cause now that i model 1/16th, the hatches are almost three times larger and the plastic is thicker, but it's worth the effort.

Good luck on the build.

Hi,
I also watched the video about using a thread saw. I tried it and was amazed. It seemed such a simple answer. Looking around the forums, it seems that using a nylon or rayon thread might be better, but I used "ordinary" thread and, although it broke many times, worked a treat. Take it easy, though, as it is all too easy to break away from the mould line.
