Ken i Really appreciate your help, and i wanted you to know it.
Thanks

Don't mention it, I'm just returning what I benefited from this forum :)
Keep reading, I too was electrically & electronic challenged, but there are enough information in this forum for me to implement my own concoction of electrical & electronics in my build. I believe if I can do it, everyone could.

Cut some Nylon involute spur gear for a customer.

The gear profile is 33mm thick the Nylon block is 42mm thick... Its a mental torture when the 5/16" x 1-1/4“ flute length router bit giving out weird scream like sound...
The cuts were super conservative... 1mm depth of cut, 1200mm/min feed 3000rpm. G64 p0.05

A customer brought timber into my shop & request for some carving.
Faced the bottom & carved the requested letters.

Can anyone make out what wood is this?
It cuts beautifully, has a waxy feel after a light cut & it give out cinnamon like aroma when the wood dust are lit.

Did some search on the internet, this wood might be Cinnamonum camphora (commonly known as Camphor tree, Camphorwood or camphor laurel or xiang zhang mu香樟木 or kusu no ki 楠の木。) but still not certain with it.

Ken,

It looks more like a Rosewood type timber than Camphor but not sure about the waxy feel or the smell????

Aromatic Wood
 

Since this is largely a woodworking site, I am sure I will be speaking to the choir. If it is an exotic board, be very careful of the dust. Allergic reactions to wood dust is common. It is of no great concern if the dust on your skin and causes a rash, but if it is in your lungs and causes a rash, you will be in grave danger. Many woodworkers develop a sensitivity to wood dust, and some have been driven from the business.

In regards to your question, here is a link to a book on Amazon: http://www.amazon.com/Identifying-Wo.../dp/0942391047
Bruce Hoadly gives a great explanation to what might be considered a dry subject.

Roger, (still stalled no table yet.)

Some people say that Elm smell like cinnamon.
Another source :
Balsam of Peru: a tree resin from Central America, so named because it was historically shipped from Peru. Balsam of Tolu is from a closely related species of tree grown farther south; both resins are said to smell like vanilla and cinnamon.

The waxiness could also indicate a member of the Teak family - and remember Roger what is exotic to you is local for Ken, some of the best "exotics" grow in his backyard... :)

exotic
 

I meant exotic, in the sense of unusual. If the usual business involved mdf or plywood, any solid wood would be exotic. Here in the southeast USA sassafras, that is usually used for root beer can grow to be a substantial tree that has a sort of eucalyptus or camphor odor when cut. Sassafras albidum is apparently a member of the laurel family, many of whom have wood with odors.

That wood seems to have rings with early wood, and late wood, indicating one season with rapid growth, and one with not so rapid. The heart wood is dark and highly figured, the sap wood is light colored. It looks like the sap wood has a little area of rot, which would mean the oil that is making the wood smell wasn't completely successful in preserving it.

I will venture that you have a piece of cocobolo (Dalbergia retusa), like all members of the rosewood family they can cause sneezing and itching and should be machined with good dust control and a mask as you can become permanently sensatized.

you can find and example image of a similar piece here: http://www.rambelgium.be/_img/142.jpg

It doesn't smell during cutting & carving.
The waxy feel I meant is the finishing touch feel like a well polished & waxed wood.
As for exotic wood, Rosewood & maple are exotic to me ;)
John, thanks for the heads up, Cocobolo! More pix of Cocobolo
Lucky me, the wood chips & shavings aren't irritating to my skin.

Those pictures remind me of a wood I found in Mexico 40 years ago that was called Xericote (or Zericote). Hard, dense, heavy beautiful. I still have several blocks I bought back then. I can't seem to find a project good enough for the wood.:)

Maybe Conrado knows!

I promise this is my last "don't run with scissors" post on this subject. One of the posts of above had a quote "There are two kinds of people, those who are allergic to cocobolo, and those who will be." This statement is most likely founded on the phenomenon of cumulative sensativity. I worked with a guy that was not allergic to poison ivy. He took great pleasure in walking through poison ivy thickets, while everybody else went around. Then, one day, apparently his immune system rebelled and he was covered with poison ivy sores. Bee stings are sort of famous for this, with each sting being a little worse until they induce a life threatening reaction. So, take a little care, and you can stay in the camp of "people who will be allergic", your whole life.

Fantastic machine you have there Ken. How does it know how to write that language ?:D

It went to our local school :D

I would like to borrow Rikschoof's words " I'm allergic to software， I get red rashes"

After months of reluctant effort to learn up Ubuntu & LinuxCNC (previously known as EMC2) enough to open a terminal, issue a few commands, change directories so that I could proceed with upgraded to current LTS version of Ubuntu 10.04 & LinuxCNC V2.4.7 from 8.04 & V2.3.4 withou internet connection.

While I was at it, , I managed to mustered enough energy to (finally) wire up the dust covered economical USD7 generic game-pad that I bought for such purpose.

I got it working following this step by step tutorial & with a little left-over energy & over-dose of excitement, I went on adding E-stop button & On/Off button. which I also selectively copied from this Joystick hal file with axis lockout. Presently, I don't think it is necessary for me to lock the axis as I have plenty of free buttons available on the gamepad, hence, I assign 2 buttons to do only +-X & 2 buttons to do +-Y.
Maybe I'll add a "Pause" & "Stop" button later... but I just ran out of energy & concentration...

I basically did nothing apart from learning how to use Ubuntu.... Hope someone will benefit from what I struggled through.
