Well, it all started with a picture. I took this shot in 2008.
It is of Officer’s Row Park here in Vancouver WA. It doesn’t snow here often and I happened to be able to get a picture of the park with several inches of snow. It was a fun shot to take and play with and I even printed out a nice sized 10×40 inch print. But the gray overcast made me set it aside.
Then, last year a friend of mine mentioned he had some maple harvested from trees that had to be removed – wait for it – from the same park! The row of trees on the right of the photo are the maples still standing. He wanted to know if I would like some to work with. Well – yeah I sure would!
When I picked up the wood, I could see I had a challenge. The pieces were trim cuts from squaring up larger pieces. They tapered to zero thickness in some places, were very rough and not the color one expects when they think of maple.
But the biggest challenge was – they were shorter than my picture!
On the plus side, one of the pieces had some spalting (I think it is the one on the right). I just needed to figure out how to make these boards longer. I was definitely NOT going to try to just splice two pieces together – the color and grain variation would never look right.
I ended up using the spalted wood as an inserts that I set off with a series walnut and maple bands. There are three different sets of bands – each one with unique patterns and/or widths. One of the glued up strips is balanced on top of the clamp handles.
I did some math to make sure I had made the strips long enough. I did, but two of the strips had exactly zero waste – sometimes lucky is good enough.
I even managed to get the spalt lines to follow the color lines in the main boards.
I then ran the assemblies through a cove cut set up.
At the same time, another friend offered up some walnut that had been harvested in Silverton, OR. I used that to create elements on each side of the maple strip.
A beveled strip of walnut finished off the inside of the frame. These pieces need another cut – each side represents one piece…
The outside was more of a challenge. This was a project where I had to design as I went along. This was my first large frame and I had trouble getting proportions balanced. I went through several attempts in CAD to get the final layout.
The outer strip is a combination of a cove cut and roundover. Here is the cove set up and resulting cut.
The round over cut took a 45 degree fence for my router table.
Here is a shot of the 2 shaping cuts. I am just getting started with the trim cuts to get the correct orientation for the frame.
Gluing these complex shapes together was another challenge. Each time, I tried a different combination of tape & spring clamps. More tape and fewer clamps seemed to work the best…
The difficulties with this glue up led to new challenges. I was not able to get a clean joint and had some gaps. I used paper thin strips of walnut to fill the gaps.
Next up was miter cuts. I had to add blocking to the back to get the assemblies level. It took a few trim cuts to get the miters right. The glue up was the next challenge. There were no square edges to clamp against. The small lip on the outside just twisted the pieces up and out of alignment. I ended up smearing glue on the joint and holding the joint tight for a few minutes by hand. That gave me a strong enough joint to handle the frame. I then added plywood reinfocing to the corners. The result is a very strong and stable joint.
But wait! It turns out I am not done! One corner of my hand held joint had slipped just over 1/8 of an inch. I am at the point of no return, so it is time for some repair magic. I cut out the mis-matched overlap and inserted the correct color. I also had to get out my carving tools at clean up the edge mis-alignments as well.
The final result was clean enough that most people can’t find the problem corner.
I used a french cleat to hang the fairly heavy frame.
All in all this was a great example of how a project can be a progression of one problem to solve after another.
The final frame is 27×57. The frame itself is about 6 inches wide.
