I don’t consider myself a very advanced CNC user, but I always wanted to build one of these, so I ordered a plan (Cephied) from Derek (I was never interested in the amount of effort to scroll saw one). I couldn’t figure out how to import it to full size, but Will described the process using other software I never heard of. Finally I realized what downloaded was in metric, so I upscaled the files by 25.4 and the parts were the perfect size.
There are many parts needed, but Derek provides a complete list including McMaster-Carr part numbers to make it easy. Some are quite specialized and the price added up to more than I expected, but everything went together really well and the finished project works really well. The price of Baltic birch plywood is pretty high now too. There is a bit of balancing, tweaking etc. but he has good troubleshooting guides.
It worked well enough that I purchased a more complicated plan (Merlot) and am building it now. I have run all the CNC parts and again, they came out great. Fun projects!
