So the good news is that I started the christmas gift projects early this year. The bad news is that it is not proceeding as swimmingly as advertised.
I am making end grain cutting boards from 8/4 cherry and hard maple for christmas gifts, mostly following the plans at woodwhisperer for this same project. I don’t have a drum sander, and my tablesaw is not quite as calibrated as I would like it to be, so I’ve put together a jig to use my router for planing the end grain surface after the final glue up, and got a bottom cleaning bit for the operation. Of course, after this there are still some machining marks on the board.
I tried using my ROS at 180 grit to remove the lines, and got most of them… but then at least one sidewas bothering me with a clear machining line. I went to a 60 grit hand sander to knock it down, which I did successfully. Hooray, right? And then I went back up through my grits with ROS to get to 220. Now I have a glassy, buttery smooth surface…. that somehow has some clear scratches on the sideI was working with 60 grit.
So…. how can this be? I would think that if there are scratches you would be able to feel them! And now that I have already sanded it up to 220, should I do the whole thing again at 60 to start from square one? Is mixing hand sanding and ROS what has caused this issue?
