OK...Life's interruptions have paused for a moment.
As mentioned in Scott's GREAT thread "Flying Walrus";https://forum.vectric.com/viewtopic.php?f=29&t=31336
This whole project wouldn't have been possible without Brady Watson doing a 360 laser scan of a 1973(?) Inuit Soapstone carving of a Walrus I love;http://www.ibild.com/
Nervous as Heck sending Soapstone Inuit carving out, as you can scratch it with you fingernail while rubbing it with natural face oils for patina!!
Wrapped in Fleece and bubble wrap,shipped, got a call from Brady asking if it was OK to Talc it (it was too shiny), and then got it back unscathed(and cleaned:) within a week
And the scan 3 days earlier in both .stl AND Cut3D format;
Had the scan for a year and a half , but was LOUSY at Cut3D....so didn't touch it till VCP 8.5 came out.
Scan was so High resolution I could see the file marks I needed a magnifying glass to see in person.
Can't recommend IBILD enough!!
May send my Inuit "Shaman" head, now I'm more experienced, and won't worry about Brady's respect for it, and the care he took.
MAY try a 2-4 sided cut sometime in future in Macassar now I have the Tiny Radius 3"TBNs and some more experience."
Got sick and tired of looking at my screwed up Walrus,
so first thing I did was take it to my stationary belt sander and flattened the backside till it got interesting, and then sanded the endgrain edges till they were now roughly parallel up to 400G.
Got a good SOLID hold down THIS time!!
Used the same exact Finish Toolpath as back then, but plugged in my freshly arrived 3" long, .25"shank, 1mmR Chinese TBN with what eventually became a .26" allowance, and started cutting down in an Offset .05" at a time(and after Feeds/Speeds tweaked, at .1" pass depth) at 10% stepover....And Down I went, Nudging my Z down before repeating the toolpath.
I didn't know how far....It was finally .75" before the bit mark Almost was gone(Wanted to save a Tiny bit to remind me about hold downs!).
Bark was only being held down by the nibs at this point because of the belt sanding, and after going down .5" had to remove it.
More cutting finished pics in a minute....
