For the last few years I've hungered to build chairs, but have been largely unable to begin in earnest. While I did make the shop stool in the SSBO a while back. many of the chair designs I want to build have been waiting patiently, generally building in complexity & nuance with each napkin sketch revision. Add to this the inspiration peer pressure from chair makers like Jeff Miller, Chris Schwarz, Peter Galbert, Paul Lemiski, and
If you also follow me on Instagram you've probably seen my other obsession is scorched & waxed finish (Shou-sugi-ban) especially on red oak. I love this finish (full stop) It has lots of rich texture and a luster like a vintage motorcycle jacket; and since I have a decent pile of red oak (a wood I am otherwise not too fond of) many of my project sketches lean this direction. BUT the scorching process is at times violent and does unpleasant things to glue (your mileage may vary) so I was hesitant to burn (and ruin) a project I had invested significant effort into. I've also been curious as to how this finish would hold up and patina when applied to a chair.
Enter the PerchThis little stool which I was late to Peter's blog for, (I think I was first introduced to by #toolmakersretreat) would be the perfect test bed for me to try out several important skills from saddling seats and "staked" joinery to the process sequence requirements Shou-sugi-ban would introduce. The instruction and videos on Peter's site are more than enough instruction to build a perch, though it's a disservice to not get his book Chairmaker's Notebook. While Peter's design sense is spot on, functionally it needed some tweaks to work for my application
DesignFirst off, the legs needed to be shortened as a consequence of its function as a cello chair this meant I needed to tweak the rake & splay a bit to maintain the same ground contact patch and avoid it getting tippy, this required a bit of trig to get in the ballpark, then rounding to a convenient angle. The forward lean and stance is good because of the desired posture for cellists. Second, I wanted to avoid turned legs; I have just a short midi-lathe and I prefer the simple (looking) chunky square legs on welsh stick chairs.
I also decided I wanted to try to play with the shape and see if I could bring in some design queues from the violin family. I introduced the C-bout into the back which doubles as a nice grab handle (and casts an interesting shadow). The concave saddling of the seat adds a bit of an optical illusion mimicking the convex arching of a violin top. Finally the tapered legs with a gentle crowning on their faces hopefully give a subtle nod to the fingerboard of a violin.
Lessons Learned (After Action Report)
- Don't trim legs until after assembly, it prevents straight line pounding of the leg during the seating process.
- Don't think you can predict and pre-finish the tenon stick out (and leave contrasting unfinished wedges), you will be wrong once the pounding begins.
- I chose flat sawn oak for the seat, since I think it's less likely to
splitself-rive than quarter sawn oak with racking forces in the seat from the legs.
- Don't drill 3/4" holes if you plan on using 1" tenons (It makes for a lot more reaming.)
- A cabinet scraper makes quick work of the scratch pattern left from a coarse kutzall wheel, way better than sandpaper.
- Kutzall wheels cut excellently, but make a ton of dust.
- Kutzall really do "cut all", including a nice abrasion on your fingertip if you forget.
- Surface checking. The scorching process opened up some checks I thought were gone during shaping. Nothing catastophic but likely a consequence of the flat sawn seat material (that started with some checking) and the risk inherent in the process.
- Crowning the leg faces really makes them richer both in looks and in feel.
- The seat position on the perch is very similar to what I did on the SSBO tilted and saddled, encouraging an upright riding posture without putting edge pressure under the thighs. My Shop stool is very comfortable, even if it's a bit ungainly from a design perspective. Pete's Perch is attractive and way simpler construction, I wish I had used this as the starting point for the SSBO.
willwould make a version for myself about 6-7" taller for my general use. I think this is the kind of seat that is very personal and tweaking it to fit perfectly is well worth the customization.
- I have a feeling I will be making more of these. Chair building fever is only intensified, not abated.
