Cut'N'Shut Suggestions

[rudilfan]

I am looking for suggestions and ideas on the best way to do Cut'N'Shuts, or rather the best way to do the Cut bit.  I am looking to make a bunch of FL9 units and short of completely building from scratch using styrene sheet (not as stupid as it sounds, but the major problem is the roof sections) I am going to have to cut a bunch of FP9 or F9a bodies.

For doing the occasional one or two, I have tried all sorts of things, and usually end up using fresh scalple blades and a stainless steel flexible strait edge.  This project is going to get too tedious to do it this way and my mind has been drifting to building jigs, or buying a bandsaw or someting motorized (beyond a Dremel).  

What I would like is a device that lets me slice (as it were) a HO F Unit Body in a single pass.

As far as I can see the problem with most power saws is that the Kerf (width of the blade cut) is going to be to great unless I use something like a Dremel/Proxxon table saw or cut off saw.  The problem with these is that I also cannot perform the cut in one pass.

I am sure someone out there has solved this, any suggestions?

I would think that using a razor saw in a miter box would be the way to go.

Then if you want to use a power tool, you can use a sanding machine to get everything tight and square.

For something pie in the sky, you could snug a length of nichrome wire around the shell and zap right through it.

How about using one of the old ATLAS FP-9 shells to start with ? There seem to be a few still hanging around.
