There are no specific instructions to be noted in order to cut this, the only thing I recommend is that you select the border, copy it so it can be saved for a second cut, and then delete it and cut everything else first. I finder it easier and safer to tell the computer to cut everything pocket wise first, then reset the bit depth on a second cut, since after every cut the machine goes back to the “home” position. the material I use for this project is one of the 17ish" wide, 6’ long glue up boards from Home Depot which are only $20. If I remember correctly, they’re right at .69" thick, not quite 3/4’ but close according to my calipers. I use the shorter 1/8" bits from Inventables and cut the collar off for the outline cut, I do this because the wood I used is thicker than the cutting depth of the bit, which you can do at your own discretion if you decide to do so, and I assume zero responsibility for anything you do decide to do. I only note this because I have had terrible results when cutting with the long 1/8" fishtail bits, bad chatter and tones of vibrations and deflection with this material, so I just tend to stay away from them. What you decide to do is your choice and yours alone. If you decide to make one of these I hope you enjoy it and get as much use out of it as I do, I find myself reaching for this thing multiple times on every project I cut. If you modify it, please upload a picture if at all possible, I’m interested to see customized version of this to suit the needs of others. Cheers!
