Sorry for your loss. My mother transcended on Feb 2, 2009 (her birthday is on the 20th) so I think about her a lot and can relate to your situation.
Thanks for sharing your work - they look fantastic being the first few. I'm carving out new brackets for my Dremel and then I might cut one for my DeWalt DWD112 drill to hold the new 3/8" Diamond Drag engraver that I just got. Actually that's a bit overboard. I'll make a small extension with a 3/8 hole to slide the bit into.
