OK, I am new to wood finishing and this might be a crazy idea.
I do not have a lot of sanding/finishing equipment yet, just a ROS.
I do have a sand blaster that I use fine walnut blasting media in.
Right now it is very clean as I just cleaned it out and put all new walnut media in.
So, regarding the sand blaster
I have tried this on a few of the things I cut with the CNC to do clean-up just to see how it would do.
I do not think it did that bad, but I could be missing something.
Is some of the oil from the shells that might be deposited going to mess things up later?
I do not notice any oil, but could it be there?
Is there some other reason I should just give up on this idea?
If this would be better in the finishing forum, go ahead and move it.
