I'm not a part of the Makers group, but I have followed since you guys<br>were meeting in each other's residences. I'm curious about the laser<br>cutter. Will it cut fiberglass, carbon fiber, and/or kevlar cloth?<br>
Not cloth with resin, just the raw cloth.<br>Now that the shop is so close to my house, I have been seriously<br>considering joining your band of Makers in hopes of learning more ways<br>to create/destroy stuff.<br><br>Rick Nelson<br>
