A 2” round Winter Tree carving in some weathered maple. Same model set up as last time. Very clean cut.

That's a Nice piece Bill! :)
What was the major difference that saved cutting time that much?
I must have my dunce cap on...as I thought when I was freshly caffeinated yesterday morning I'd understand..but still don't :oops:
Step by step the new cutting strategy please?

I usually do the Profile toolpath with my Finish cutter also before carving once I know my final depth...
Usually a Spiral Ramped cut "Project onto 3D" of about .0001"..so barely noticeable(unless I muck something up:)

Spalted Maple that had bark almost falling off..and then removed and just smoothed and oiled?
Looks like a comfy diameter and texture:)

Thanks Michael.

Hi Scott. I was a little over an hour before and down to the low 40 minutes after. Basically I think because I eliminated the dish that eliminated a lot of Z travel which I have set at 1/3 the speed of XY travel. Some Z travel also eliminated by rastering up and down v. Left and right. Went back up just one percent on stepover also, so a lot of factors. Tree cut came in at 36 minutes.

Yes, on tree all bark was gone except light remnants easily removed. Then I waxed the outside with carnuba/beeswax/mineral oil mix. Danish oil again on carve.

Thanks Bill!
Can your machine handle increasing Plunge to closer to X,Y Feeds?
I SHOULD shut up as you know your machine :oops:
I was looking at control computer file of Owl(the very first one for my step-mom in the walnut branch) and I had Drillman1's .125" longer downcut moving at 1.5IPS in all axis, and it was cutting great in .05" passes at 37% stepover.
.17.19 Joan's Owl roughing Drillman 1.jpg
Roughed second one for me at 50% stepover and .06" passes, and still good, but branches fairly dry at that point last year.
1.7.19 BLACK WALNUT OWL2 ROUGHED 50PERCENT.jpg
Is wood still pretty wet? You seem to be getting Great,Smooth cuts going with the grain on that Maple:)
May have to try with the grain with my spalted Maple that's still a hair wet :)
I got kind of a Velvet Fuzz on wet White Birch cut....and Angel WAS smooth, until a couple Fuzz spots showed up overnight even with 50/50 Linseed/D-Limonene coated immediately. :( NOW manageable as I burnished them and got LinWax on it immediately..2 coats now and much better(thank goodness!).

Yep...I LIKE that black from totally loose bark!
On my Walnut branches, that Only shows on sections of bark that pretty much come off with just fingers, and a hardwood burnisher.

Thanks again Bill:)
I LIKE seeing the refining of your method:)

Scott,

My machine has simply supported X and Y shafts and HDPE carriage. So even though I rebuilt carriage with aluminum, I still get flex if I push Z too much, so I stick with this formula.

Yes, the maple was pretty wet still but cut well, just a little fuzz that I was able to brush off.

Well on to what's next!

Yep Bill...Like I said...YOU know your machine :oops:
FUNNY...People have said for years for me to change some settings on my machine for faster 3D cuts(Shopbot VR)....
So FINALLY today took got nerve up to try some standard tweaks from Brady on a Small slice of "Angel" after running the slice in my defaults.
Default setting times for 1mmTBN was 7:21 with a scale factor of 3.2

Tweak setting time was 4:58 for the same exact toolpath with a scale factor of 2.15!
OUCH! :oops:
Running the .25mmTBN Finish cut now..and wondering how many days of cut time I could have saved.

OK...I give UP!!
Is that a new front for rural mailbox with window to see if you have mail? :)

Great work Bill......I learned a few things! :D
