Happy to hear that my blog helped you get started in CNC. I envy your 4'x8' bed.

Thanks for the tips. I seen a youtube video about gluing the tape together trick but haven't tried it. I've been having relatively good luck with carpet tape. I'll maybe have another look at gluing the tape together.

I figured out the trick of moving large pieces over the router bed using and index hole. I'm limited to 21"x15" but cut my turtle deck floor and my floor boards. The floor boards or 72" so I cut them in 4 separate cuts by moving them in the router. I haven't cut the final version, just prototypes from press board. My blog on the turtle deck is here:

I also used the match hole cutting to make my seat frames.

A side effect of drafting all the parts for CNC is that I formalized the drawings and have a nearly complete set of As-Build drawings for my project. Useful as I deviated from the original plans in a lot of places. Nothing structural, just cosmetic.

Good luck on your build. I'm pretty sure you'll find more uses for CNC on your project than you could imagine when you started.
