I haven’t seen an mpcnc waterjet yet. When I can’t sleep I hit up YouTube to either entertain or put me to sleep.

I would love to cut steel sheets if I ever make it back to kitchen knife grinding.
That seems awesome. There was a topic here a while ago and someone pointed out that the waterjet can push water and sand into your bloodstream. That’s terrifying enough for me to skip it.

And previously for the good of the order:
