That's an awesome idea!!! What do you suggest? Something super simple...I've never done a scratch build plane before. This would be a good learning experience for me. I have plenty of parts lying around too.
I have it all laid out on a big sheet of foam board I got from Hobby Lobby. This stuff is hard to cut, am I doing this right? I taped the pages together and tacked it to the foam board. Now i'm cutting along the lines with my trusty Hobbyking 8 Point snap knife. This stuff is so hard to cut its stupid.
What thickness is your board?
It is easier for me to use Xacto blades, epecially for the slots. Remember also that you have to cut at an angle, 45º or more (between the paper and the knife).
Hope this helps
Utility knifes (box cutter with changeable blades) work best for the paper covered board. The paper dulls the blades quite fast so you need to change ends of the blade and blades rather often. I save them and reuse them for other cutting needs that don't require a quite as sharp as new blade. I use an X-acto hobby knife for fine work.
These guys have some good tools for foamboard work:
I found it easier with this type of foam with the paper on both sides to score through the top layer of paper then through the foam...making about two or three passes of cuts instead of trying to cut along the line in one cut.
