I thought I would show some of the process that I use to make my Parallam furniture. I recently built a Convergence table- my parallam coffee table and took some pictures of the steps along the way.
Parallam is an engineered wood beam made by weyerhauser. They are constructed out of many thin strands of veneer in order to create a massive beam far bigger than the trees used to create it could have yielded. The environmental benefits of parallam are simple: You can get bigger pieces of wood out of smaller trees, and the yield from these trees is much greater than conventional processes. Trees are round and lumber is square- this produces a lot of waste. The veneers used in parallam are rotary cut, utilizing the tree in the round. Rotary cutting is best compared to unrolling a roll of paper towel. Thin wood (veneer) is sheared off in a continuous sheet and the trunk gets ever smaller. After the veneer is cut, a post is left over- they sell this as well. In fact when I queried weyerhauser they reported 95% yield from the trees they are processing- quite outstanding.
Parallam is intended to be used in Architectural structural application where exposed beams are seen. In my opinion it is pretty cool, but the best part is hidden away. The end grain of a parallam beam is a wild scramble of woods. I set out to build furniture that exposed the end grain and highlighted its amazing grain.
The beams I am using are made from three woods, Poplar, Spruce, and Southern Yellow Pine. All are fast growing domestic woods which have traditionally had limited appeal in high end furniture. Here is my redux.
The beams I buy are 18′ Long. This one has been cut in half. It is about to cut again. It is a lot of beam, but what I am after is more of that little patch of end grain.
I use my 30″ tannewitz bandsaw to cut the beam into smaller, more manageable chunks.
Over the 20″ wide Oliver jointer. this puts a perfectly flat face on the chunk
… and through the 18″ wide Oliver planer. This puts a parallel face to the jointed face.
The beams already start to reveal their inner beauty.
Next stop is back to the jointer. Now I am establishing a perpendicular edge
next is the tablesaw. The 5″ thick board is too thick for my saw, so I cut twice. In this shot, the board has been flipped and I am making the second cut.
I am back at my bandsaw cutting the chunk down again. here I am making a very straight cut which I can reference against the tablesaw fence
And back to the tablesaw using the cut twice adage.
After a bunch of cuts, I finally have some of that end grain showing
I glue the chunks back together to start to re-establish the width I just lost.
My next step is running through My widebelt sander- It is actually one of the narrowest wide belt sanders on the market. it is a 12″ wide made by AEM. I added the stainless steel covers when I rebuilt the machine.
The sanded blocks now make up quite an expanse
They are glued together again
Once glued up, I square the blocks up on my hammond glider saw. These saws were originally used in the printing industry to cut lead letterpress type.
Two blocks ready to be made into a table
Thanks to everyone who stopped by this past weekend at the Baltimore Craft Show. It was a successful show and my spring schedule is getting to be quite full. I am now back in the studio and preparing for my next show- The Smithsonian Craft show. That is held April 22-26 at the National Building Museum in Washington DC.
Here’s a shot of my booth in Baltimore.
If you want to skip ahead, my piece starts at 2:24 into the clip.
I had a photo shoot yesterday with Tom Stock, my photographer in Saratoga Springs. I decided to go for a different look than I have been featuring with my furniture, and Tom expertly pulled it off. Here are the latest images and a sneak peak at two of the brand new designs I will be exhibiting this spring.
First, the Helium dining table- made from jet black Mahogany, glass, woven stainless steel cable and a custom milled aluminum corner bracket.
Next the Torus pedestal table In Mahogany with concrete and stainless steel cable.
I also had him shoot an Axis bench with a dyed black Mahogany top rather than the Parallam top the original bench was built in.
Lastly the Convergence Coffee Table featuring Parallam and Mahogany.
