I have mine adjusted to give half and one third sizes and one variable if I need quite a few of one size
The other cutter is usefull for repeated angle cuts
After building sections cutting/trimming to size I usually use a fretsaw
Bending matches I recently aquired a bandsaw and built the bender
I soak matches in hot water for half an hour then clamp them,
leave for a few hours,you can then tweek them with gentle pressure with your fingers to suit.
I have a sheet of dense cork about an inch thick ideal to accept pins.
Cut a pattern to shape wax the edges and use greaseproof paper
position and glue matches.
When building my boat I screwed some blocks to some wood and clamped the keel
which left both hands free to position and glue chines
If you have unusual gaps to fill leave a largish space glue two or three matches together
a lot easier to hold and shape to fit.
