I’ve had no problems with cnc. (well, except for when I tried to do a 2mm step down with a 1/4" bit in some really hard knotty oak and ended up having to adjust the play in my x-axis) Can’t push step-down as much as I like but other than being a little slow had no problems with results.
@sdj544 I will go down on my knees and honor to you!!! @MooseJuice Let us take a little break and then we (perhaps i meant me) be back to the frontline again.
thanks for your words! For you and perhaps your family? stay clean and healty and have a nice 2021

Thanks!
A lot of tool paths with smaller and smaller bits. Start with 1/4" for clearing and work my way down to .8mm. A couple of them were around 6 or 7 tool paths plus contour to cut out. I measured the bits to where the shoulder starts so I get as much length as possible. A lot of bit profiles (including SM) lists their cutting length and you an actually push them beyond that. If you want to cut really deep (without a lot of planning) you end up limited to the shaft width. So the nativity I was only able to use 3.175mm ball end for final pass. Other than getting stock to starting size rectangular block I used SM for everything (including cutting slate) - no band saw or scroll saw.
Been trying to put together a walk through, but too busy making stuff. Just got recalled from furlough so not sure when that will happen now.
