I am blown away by a recent revelation over at the Facebook group: people use downcut endmills in wood without dust extraction nor workholding, and let the compact chips/dust hold the workpiece in place??
I saw some videos and do believe it is possible, but this seems incredibly sketchy!
This sounds like madness and an inevitable disaster, but apparently more people than I expected use this method. I am in disbelief. Am I in the minority here?
It is true that down forces are acting on the work piece but there are side forces at play as well. Maybe it works for them but I would not want to be babysitting a project with no clamps or other workholding. I value all my extremities and eyes too much to try a down cut with no clamping. Maybe tape and super glue but just sitting on the wasteboard, no no no. The same for a bunch of shifting chips and/or dust, no no no not for me.
