The eucalyptus project began as a suggestion from my beautiful wife Elaine that we help this guy out who had this tree fall over in his yard & sounded like he just didn't know what to do with it.  Maybe some firewood, maybe we could just help him cut it up & get rid of it . . . well . . .once we got there . . . It was quite a different story . . . read on: 

The story goes that the guy who lived there & who ran the ad in the paper moved to the house in 1948 after WWII . . . At that time, the Air Force made him cut the top of the tree off because it was interfering with the landing flight patterns of the planes landing at MacDill Air Force Base!! - that was 55 years ago! -This tree I suspect is probably over 300 years old!!!!! Amazing . . . just look at the grain in the thing!

You can just see the shimmer that will appear in the wood once it is planed & finished . . . Note the change in light  from light to dark & shimmer to flat in the cut edge of this huge log! . . .

Above & Below:  These photos give you an idea of the size of the tree! - about 5.5 or 6 feet in diameter at its trunk base . . . The thing was immense! - the owner was thinking that it would make some good firewood! - what a tragedy that would have been! - an utter tragedy: - just look at the grain in this stuff! - it is amazingly beautiful!

Above:  This is what a good day at work will feel / look like . . . There was a layer of saw dust . . . No joke, a 1/2inch thick on my arm!--was all tired out, sweaty . . . Felt great!!  This was after about 6 hours of cutting the tree with a 3' long, 3 horsepower chainsaw . . . Would cut a person in half!! . . . The glove is a welding glove used to control vibration transfer into my arm from the big saw.

Below: That's my brother Dave in that photo using the huge chainsaw! - that thing was huge!

We figured that wet, (which this tree was) the entire log weighed in at about 26,000 pounds! - that's about 6500# for each quarter--we had to use 4000# wire rope pullers & chains to drag the quarters onto the 3 axle trailer--to move forward with this project (which was going to be expensive one could tell)  one had to be able to envision what the wood could be . . .   


The pipe at right was safety in case the chain saw caught & kicked out of the opening--so that it would not cut one of us in half!

That's my brother Dave standing next to the tree with his arm up in the air . . . That was a huge tree! . . .

Below:  photo frames made with some of the sapwood of the tree.

Main door to the Ruskin House. Door made of Eucalyptus Burl from the tree.  Door measures 9' square, is 3.5" thick, weighs 550#, and rests on tapered roller bearings in an offset pivot configuration with custom designed and fabricated 316L stainless steel hardware.  Door pins open to create a space and air governing panel.  A book about the Ruskin House is available at Blurb.com

Above:  John Langley stands here in joking wonder--(complete John  fashion--"You can't do that!!") at the project--as if he completely expected something like this from us, but is all the same just laughing  in astonishment at the event.--John is a steel sculptor:

And does amazing things with found steel objects.

A Pool / Poker table fabricated partially with Eucalyptus burl from the tree . . . the Geared Motion Pool Table--In collaboration with Hurricane Billiards of St. Petersburg.  The website can only be found now on the waybackmachine.  Web.archive.org

Above  What this was all about was that we had to take the logs up to High springs to a guy who had a portable, hydraulic saw mill capable of milling the logs into usable lumber--4/4 boards . . . Check out the machine:

Below:  The World Youth Day Cross  . . . The base is made of a chunk of the Eucalyptus burl.   Polished and filled.

Below  Underside of the World Youth Day Cross Base from 2011.

The 13,000# load on the 3 axle trailer pretty much sank it into the ground and of course the '95 GMC 1/2ton was not able to pull it out . . . So we had to link my brother's 1970 ford 3/4ton to the GMC with a 20,000# nylon strap & were able to pull it out that way--barely!! -

Right:  At the end of the day--it made a great beer hall table . . . No more cutting or heavy lifting at this point of course--just imagine a pub with this as the table . . . That would be one of the coolest things!

Dave Fraser's Big Green Egg Grille Table    --design by the late Dave Fraser

This officially was the first project done with the wood . . . Also known as Austrailian Mahogany . . . A grille table designed by & for Dave Fraser's Big Green Egg.

Below:   The grain is like water rippling over rocks . . . Like sands blown by the wind in the desert, like clouds scattered by the wind . . . Like air currents drifting with fragrant scents . . . Natural beauty in its purest form  . . . God's creations!
