I had to get a new Cricut machine. I got the Maker 4. It cuts balsa and basswood.

Here is what I have figured out so far. If you have a better way I'm all ears.

These are my videos.  I've gotten better since then.  In fact, this evening I drew up .svg files for Ace foam wing ribs.  I'll have to cut them out soon.  A fellow club member has been bugging me for a plane kit.

edit:  Just saw that my original post on using the Cricut is at the bottom of page 2 in this section.
