Vidar Chairs (Under Construction)

Tuesday, April 22nd, 2008

The following are photos taken of the chairs while under construction. Unfortunately, I wasn’t able to document this project as well as I would have liked, but I did manage to take a few pictures along the way…

Glue-up of one of the lumbar rails. The lumbar rail for each chairs consists of 5 - 1/8″ laminates, sawn from a single piece, then glued back together in the correct sequence. After clamping, the piece will “spring back” a little, but will still be remarkably strong.

Back-Assemblies of each chair, after glue-up. The lumbar rail (from the above picture) is the top-most horizontal member of each chair. At this point all glued-up pieces have been completely shaped and final-sanded.

Dry-fitting the front leg-assembly to the back leg-assembly. The front legs and front rails are glued together, but the upper- and lower-side rails need to be adjusted to give the chair the proper “stance.”

vidar-chair-construction-10.jpgTest-fitting the crest-rails to the chairs. Each rail was sawn and shaped from a 3″-square block, mortised, doweled, then final-shaped before fit-up.

Gluing up one of the back assemblies. This was by far the hardest part of the entire project. Each back-splat had to be sawn and shaped before they could be joined to the lumbar and crest rails, and all six joints (two each for the back splats, one for each leg) had to “land” at the same time. It took a week to get the first back-assembly glued up. Now on to the next chair, and after that…maybe a beer or two.

vidar-chair-construction-13.jpgBoth chairs with arms dry-fitted to the back legs. The arms are left oversize until now because I wasn’t sure how much shorter they would get while fitting those joints (answer: much, much shorter…)

Arms being glued in to the second chair. The arms themselves will still require some shaping after glue-up.

Shown here is the original Vidar chair, built by none other than Vidar Malmsten himself. The chair belongs to Mr. Krenov, who insisted I take it back to the shop (from his kitchen!) to have a look at it and take notes. Take notes on Krenov’s kitchen chair! WHAT? To an unabashed wood-nerd like myself, this is just about the coolest thing possible, under any circumstance. The best I can do is try to catch some of the excellent vibes radiating from it, and for for God’s sake, not scratch it.

The Liberon Oil seems to go on pretty easy - the good news is that it is thin, and therefor easy to wipe on and wipe off, and flows into corners well. The bad news is that it will end up taking five or six coats to get any kind of “build” to the finish.

Starting to weave the Danish cord seat. The front part of the weave must be “packed out” to account for the trapezoidal shape of the seat.
vidar-chair-construction-18.jpgAlmost finished packing out the front of the seat. The next stage will be the “Figure-Eight,” which will loop around all four sides of the seat. After that, the “Bridge” (the crease you see towards the back of woven seats), which is woven in a figure-eight from front to back.
vidar-chair-construction-19.jpgThe last wrap. Almost there…
vidar-chair-construction-20.jpgThe very, very last step: Masking off the entire chair with paper, and Scotch-Guarding the Danish cord. This should protect the seat from dirt and dust, at least for a little while.

Finished! Total working time: 700 hours.

Teak Showcase Cabinet - It starts with a curve…

For my next (and, unfortunately, final) piece while here at College of the Redwoods, I wanted to make a small-ish wall cabinet using both veneer and glass. I had a rough idea of the size I wanted to make it, but I first needed to figure out what sort of curve (either concave or convex) the front of the cabinet would have. Shown here is a plan view drawing of the door, with lines for the glass panes and mullions drawn in.

Once I had a good idea of the way the door was going to curve, I was able to make a full-scale mockup. This would (hopefully) tell me two things: 1) How the various dimensions relate to the overall volume and scale of the piece (Taller? Wider?); and 2) How the curve of the door relates to the rest of the cabinet (Should it flatten more in the middle, or should it curve more?)

Once overall dimensions have been firmed up, full-scale templates are made from the mockup. Shown in the foreground are the three templates used to make the bending form (shown behind): one template that is an exact copy of the curve from the mockup, one template with an 1/8″ more curve on one side to account for the springback of the laminates (more on that later), and the final, “master” template, which was made by mirroring the springback template across the its centerline.

Closeup shot of the old-growth plank of teak I bought/begged (mostly begged) from my friend Andrew. The plan is to slice it up to make the door frame and exterior veneers. This is the sort of board that you go to sleep thinking about, and wake up excited about…

One thing I have learned here at school is that when making a cabinet, you always build the door first, then the case. The idea is that it is easier to correct for any errors in the door by fixing the case, rather than the other way around. Although it seems counterintuitive, constructing a piece this way actually gives you much more control over the final product.

Anyway, because the door is the first thing to get built, the laminates of the curved stiles of the door are the first parts to get sawn out. In this case, one small block will be resawn into six thin strips, then glued back together over a bending form to make one curved, 5/8″-thick part.

The laminates being glued up over the form. I used urea-formaldehyde glue, which is apparently very stiff, and and has very little “creep” over time. One down, two to go…
