Playing with Burl:)

Postby scottp55 » Sat Jun 02, 2018 3:32 pm

Met "Bobtail Farm" at Leo's Meet and Greet last year, and Brian has visited the house a couple times since and each time gifted me with some Maine Burls :D
A lot more info on the Shopbot Forum
http://www.talkshopbot.com/forum/showthread.php?24487-Playing-with-a-free-burl-)&p=201340#post201340
but was to lazy to post everything here also:)
Can't raise dust in the shop, as both pieces are drying.....SO
This big Maple burl barely fir on the machine, and needed some bark chiselled off because of my 5.5"Z
Z1 and Z2 and Home had to be set at .02" for this to work with my bits :D
Pretty straight forward, but mainly to have people aware of what may be in the woodpile or being carted away by your tree company:)

And here was the first burl....Yellow Birch sapwood burl with BRILLIANT "Flame" figure!
Interesting insect patterns just under the bark on 80% of it.
Organic shape so I went with with a line segment, then copied and rotated .5 degrees, alternated the Start Points, and circular arrayed it 360 times,and trimmed vectors to my boundary vector.
Used the Fluting toolpath LOTS of times, but only on geometric shapes...cutter makes a BIG difference on this 2.5D toolpath.
Finally went only .5" deep as it's for displaying minerals/Opal probably, and went with my .5"Ballnose rather than my .5"Centurion FEM Downcut, mainly because I like the shape better rather than any cut quality issues.
The grain followed the shape of the burl, so virtually an end grain cut...oiling the surface an hour before cutting produced a cut that was like shaving with lather vs a dry shave with a dull razor :D
Pics don't do the figure justice, as it's chatoyant like "Cats Eye", and the light moves as you and the light do:)

And here's how the small burl shaped up....still 3 more coats to go on the top and bottom.
Still have to burnish/sand the sides before finishing them.

Chatoyance is a great word and your burls are outstanding. I have a router planning sled that I use to flatten pieces like that if I want to use them as boards. My cnc would do it just fine but it's fun to install the large router on the sled and manually work it back and forth. Regardless, the wood is outstanding and thank you for sharing.

Thanks guys!
Yep a sled would do it, but with me at wheelchair height, it usually means mask/goggles/ bandana in the driveway while swatting bugs:)
Besides, I enjoy seeing the different patterns emerging and I can be hand sanding at the same time.
On that big one, there's a hole that if I had gone down another .2" The hole would have gone all the way through.
And on the small one, I was really afraid of loosing the brightness of the figure.
My initial thought was to make it 2.5" deep and follow the growth ring pattern, but got some really funky ridges in preview, and didn't want to sand endgrain in tight spots by hand very much:)
I looked at some of the other impromptu displays in the house, and all are shallow(like a Red Abalone shell, and a scallop shaped opal glass piece) and it hit me that my wheelchair height would keep me from seeing what was in the bowl on most of my counter heights.
Getting fond of the small one, even though it's not as I first imagined.
I wound up skimming the bottom TRYING to get to the figure, and ALMOST gave up when the last .02" cut showed a little "Flame", and another .02" skim cut and the bottom was as shown:) Also MUCH more stable now that the bottom has more surface area and isn't top heavy....ALMOST would trust it on my windowsills where the cat manages to tip stuff on the concrete floor on a regular basis.
Small pockets on bottom to glue in the leather circle feet, and put info on back and sign it, and then 2-4 more coats and I'll be done:)
My Dad hinted Father's Day was coming....I said "Dream on...It's MINE!" :D
I like both sides of the large Maple one, so making a slab side/mobile base/ side table with all wedge joinery so it will sit on top and I can flip sides depending on my mood. Room for camera/binocs/ and reference books underneath located at my back atrium doors that look over the beaver pond 30' away...
I spend at least an hour a day drinking coffee and critter watching...so going with my Big Leaf Quilted Maple for the side most likely:)
Be my first small furniture CNC joinery:)

Scott - you are an amazing guy.

I am soooo glad I put that meet and greet together. I got sooo much out of it and I guess others did as well.

I wish I could do it again, but I just have so much on my plate there is no time to assemble another one. Maybe in the future, but not this year.

The burls are beautiful and I just KNOW that you know what to do with them and that they will be beautiful in the end.

Thanks Leo.
Too bad about your busy season...it would be nice to do again!
That was REALLY a nice day for Ron and I!
Vectric people are GREAT! :)
First thought of course was to offer my place this year....BUT methinks I better ponder on that a bit considering my housekeeping!!! :)

Yep...no problem finding a place in the house for these:)
