3D topo Katahdin Cocobolo

[scottp55]

Tallest Mountain in Maine, and kind of a "right of passage" to climb Katahdin for us 7 kids(translates as "Greatest Mountain").
Dad said he needed a piece of wood to "knock on" in his truck, sooooo...
Cocobolo was a gift from a guy who makes Scottish "Short Pipes" for a day Demo'ing Desktop.
Couldn't seem to get the hang of Paul Rowntree's Big Topo(might have helped if I had read .pdf and done his sample all the way through ops: )
But got this off of Yeggi;

Going to have to "Tip" that guy
Onsrud .25" 30engraving bit with .005"flat.
20% stepover at (IPS) 1,1,18K carving against the grain with no roughing cut.
Straight off machine with no sanding, light coat of my Linseed/Beeswax brushed on last night.

Awesome! I live in Maine and have climbed Katahdin a few times.

A very nice idea...and well done.

Thanks guys!!
Been prowling the stacks looking for a larger piece of wood with a decent grain pattern to make a bigger one for ME

8/4 scraps twice the size of Dad's were thin on the ground, except one piece of Lacewood.
Hope the heck it comes out decent....should be done about 6am
Going to be a long night
Fingers crossed.

That came out nice. I would like to do my area but have not taken the time to learn how to do all the work on big topo, maybe over the winter when it slows down a bit.

Yep, I think your area would look good(Just Google Earthed it.
Paul and LGM have been tweaking BigTopo just recently to make it easier;

And that X,Y,Z scale factor sounds interesting.
LGM just did some foam(and he must have been thinking of me when he said READ the .pdf, and DO the example ;

Lacewood was a BIG mistake to start. Put a thinned coat of Tung on it to keep dust down, but went to look at 10pm and it had pulled up grain fibers like crazy.
Paused to see if fibers would brush off(NOT)....and THEN pressed Quit instead of Resume......and called it a day after duplicating toolpath, and changing it to an Offset/Conventional cut.
Started running that today at 10 after having a fan on the Tung all night to let it cure a tad...seems to have helped a lot!
Another hour to go.
Should have left only a .02" skin, and maybe have used a VERY thinned Laq coat(or 50/50 thinned oil) to beef up those "Spots" in Lacewood.
Where Tung penetrated on endgrain, it appears VERY smooth.
Dense, close pored wood from now on, and I'm going to keep my eye open for for a slab with close to horizontal growth rings as I think it may resemble/accentuate countour lines. Wishing I had some plain Vanilla Maple slab now Quilted and Claro aren't really suitable, and the Teak would look nice but kill bits.
Pics later,

Used an offset toolpath on this(conventional and down to 1.5,1.5, 18K) to see if with or against the grain is best for Lacewood.
Area on right was against the grain, but I had paused machine and used a stiff shoe brush that had a little Linseed/Beeswax on it, so not a true example.
Worst fuzzies were with the grain, where sharp verticals were.
When I noticed that line, I tried a Spacebar Pause to Nudge, and there WAS no Nudge in the box? Latest SB3. Did nudge go away on latest version?
Maybe I need a new install?
Pics were last night with just a 90PSI blow off.
Burnishing/rubbing/sanding now, and looking a little better.

I over reacted (again)
A GOOD stiff Horsehair brushing with a Shade of LinWax and then burnished with a Bamboo skewer worked great
VERY light burnish, as that pithy area is easily deformed.
Whew

Both turned out great. Not sure which one I like the best. Sounds like more work went into the Lacewood. The one with the shortest finish time would be my favorite.
