Thanks for the comments guys
(And Ed, thanks for the thought, and congrats on the case study...Nice to finally know your name is Ed too:)
Yep, not much CNC on the stands..but the Hearts were my first 2 sided 3D, and without Beki's "Bowl" tutorial I would have been a little stumped.
I'm avoiding 2 mistakes I made with my only prior CNC Ebony chunk project for Mom years ago!
I had wet sanded the Ebony with a Tung mix to 600G after surfacing top and bottom, and added 3 coats before I cut.
And Mom came in and I proudly handed her the chunk before cutting, and told her it would be the material her Christmas present would be made of, and she said;
"WOW that is Heavy!.....What kind of plastic is it?"
On this one I left small imperfections, did NOT wet sand, and carefully watching my finish so you KNOW it's wood!
Also on that first one, I learned Ebony(and Red Gum) don't like the heat generated by a stationary belt sander! So this one was a matter of 20-30 seconds sanding, and then letting it cool to just warm,over and over to put the 4 degree bevel on the sides.
Mom's from 3 years ago,got overheated when I sanded the end grain, and a stress crack developed and needed 2 butterfly "Twig" wedges, that kept it from spreading
Got some VERY fine chips out of this cut...the only way to tell they're chips is magnification, and the way the direct sun reflected off them.
Got a nice portion of a freezer bag full now to use:)
Mom's Stand developed as those two River Red Gum "Scraps" just seemed to be aching to become something.
One day while a bunch of 3D's were finishing....I decided to jig one up and play with for the 20 minutes I had to wait.
I pulled up the Heart file/renamed/ and eliminated everything but the Boundary.
Chucked one of the 3" long(about 5degree taper) Chinese 1mmR TBN's in, and did a spiral ramp Profile cut for a center of material cut plus the radius. Then gradually increased the Offset until it was cutting,and kept offsetting till all toolmarks were gone on the first side.
After wiping/brushing the 3D's off...I was ALL excited to cut the second side, and ALMOST ruined the scrap as that bit DOVE for the spoilboard!!!
I had taken the 2 sided 3D,and FORGOT to check my material set-up!!
It was set to Z-Zero to the same face! ALWAYS check your material set-up when using previous files!!
If I hadn't set my Jog speed low from a previous cut...it WOULD have been scrap!
More later, as Mom's is a little more demanding, and have to bend 18K wire before my next cuppa, and hands start shaking:)
