Canoe-Strip Canvas Series

After completing my canoe in 2013 I had quite a few strips left over that I had planned to use for something but I was waiting for inspiration as to how I could best use them.

Finally, over the past summer, I realized I could create interesting shaped "canvases." Going Aboard was the first. I was listening to Moby Dick a lot at the time (all the way through twice and then on shuffle with the rest of my music for about a month more) so I think it was fitting, on a couple of levels, to name it after one of the book's chapters. (Photo credit for all the subsequent images are RL Photo Studio, Burlington, VT)

Upon seeing the series, a friend implored me to get a 22 gage pinner to hide the attachment method. The result is definitely cleaner and less distracting. With this one I needed to mill new strips, this time out of curly maple, cherry, and walnut.

The Gam is another Moby Dick inspired title, it refers to the meeting up and exchange of pleasantries of whaling ships on the seas and though I wasn't thinking about the chapter when I made the piece, when I was looking for a title I realized the word expressed what I had in mind in designing it.

I was reading a book by the Dalai Lama over the summer in which he mentions that it is a good idea to have images of the Buddha around one's home. In thinking about it, and why I didn't have any, I realized I didn't like any Buddha images I had ever seen and that if I would have one that I'd like, I'd have to create it myself. With Follow Wisdom I wanted to abstract the image so that the concept of the Buddha would be more important that the specific person that modeled for it. Additionally, I chose to create radiating rainbow colors because Buddhist texts often refer to Buddhas dissolving into rainbow light.

I was in the Washington, DC area the week of the presidential election, going to museums and galleries, and seeing a lot of word art. I generally get annoyed by word art, probably because of my dyslexia, but on my way back to Vermont the two things were on the front of my mind when I was inspired to create a series of pieces that just said "ART?". As a dyslexic, I appreciate its brevity, but what I really love is its ambiguity. What is it asking? How many different ways can it be read? What is/are the answer(s)? I see it as a starting point for open-honest dialog, which is badly needed right now. 
ART?(1)

Because it can be read so many different ways, I feel it is a question worth repeating. For my second ART? piece, I rework a canoe-strip canvas that I "finished" over the summer. I like that it isn't immediately obvious what, if anything, it says.

I also started reworking some experimental "shellac paintings" I created back in 2010 by painting acrylic designs on top. I think the play between the acrylic foreground and tinted shellac background is interesting.

And finally, I had rough-cut Obsession back in 2014 but left it lying around the studio for a couple of years. Again, listening to Moby Dick gave me inspiration to finish it. The title refers to both Ahab's quest and to the act of creating this sculpture.

Cross MacKenzie Show Installation Pics

I installed my show of new striped paintings/sculptures at the Cross MacKenzie Gallery in Georgetown (Washington, DC) on November 11. The show has been extended one week, now being on view until December 15. Originally, the plan was to install eight pieces so I brought twelve to give the gallery a selection of work to choose from but, fortuitously, we were able to hang all of them. Though it is difficult to see, we installed four pieces in the front window, including three of the one-sided paintings.

Though we hadn't originally planned on showing my canoe, the gallery director found images on my Facebook page and asked me to bring it. This canoe is absolutely not for sale but I agreed to let the gallery negotiate a commission one. I love the idea of it being considered a work of art because I built it with that idea in mind. I also agree with the gallery that it gives the viewer a clearer understanding of my art.
Even though we hung more pieces than we planned, I am happy with how much space they have, I don't feel they crowd one-another at all.





I hope you get/got the chance to see the show, the work really is much better in person. Additionally, the gallery has agreed to offer my bumper stickers with the same conditions that I do. I left some of my last three designs (#28, #29, and #30), so if you do stop in, you would have the chance to acquire at least one of my pieces for free.

Building A Canoe: The Finishing and Floating

At the end of April it was finally warm enough to pull out the canoe and finish it. All that was needed was some final sanding and varnishing. I went over the inside and outside with my Festool sander using 120 and 180 grit pads then hand sanded with 150 and 220 grit before brushing the first coat of varnish on. I choose System Three spar varnish because it is what they had at WoodCraft and I didn't want to buy it on-line, pricey stuff though, I paid $38/quart. I choose the satin finish because I thought the canoe didn't need the extra glitz and because satin doesn't show scratches at much.
System Three Spar Vanish

I guessed that two quarts would be enough without doing any calculations and, luckily, I was right (Gil's book didn't provide any guidance). I was able to apply three coats, inside and outside, plus four coats on three paddles and used only 1.5 quarts. The label says 350 to 450 sq-ft/gallon but I seem to have gotten more than that (assume an average of 3 ft wide x 16 ft x 2 sides x 3 coats = 288 plus three coats on the seats, yoke, and paddles equals about 300 sq-ft for .375 gallons = 800 sq-ft/gallon). I did thin the stuff with paint thinner a couple of times but mostly because of evaporation during the application. In any case, two quarts seems to be the right amount for most canoes.

I used a 3" Purdy synthetic bristle paint brush and didn't notice any brush marks -- it dried smoothly. I didn't sand between the first two coats because I put them on within 12 hours but then sanded the with 220 and 320 grit sand paper (by hand) before the final coat.

Here is the finished piece. The final weight is 66.6 lbs (I lost 0.2 lbs in the final clean up, mostly in the decks as I had to get them to match the level of the shell). Given that Gil said this design would weigh in at approximately 65 lbs, I'm pretty happy since I used lumber that is much heavier than the cedar he uses. I'm sure I saved much of the weight in the seats.

Over the winter I prepared three paddles, (58", 63", 68") out of my mountain of old barn flooring that I have stacked in my backyard. I wasn't sure it was a good choice but it was free and at the very least it was good practice material. It turned out to be a good choice  in terms of looks, weight (I got them all down to 2.6 lbs), and performance, but dealing with all the knots made it difficult to shape and probably doubled my working time. I wasn't sure how to make them but soon realized that it is just the same as any sculpture, remove material with finer and finer tools until you have the shape you want. The key was in copying the plans from an old paddle that I liked and using the shape, transferred to a board, to rough cut it the shape on a bandsaw. Then using a draw knife followed by a spoke shave to get an approximate shape. Unfortunately, the high number of knots in the lumber made those tools particularly difficult so I eventually started using a grinder to work through the knots and get the blade as thin as I needed (about 1/4" at the edge). Then my Festool sander working 40 grit to 180 along with a rasp to get the handle shape. The final step being hand sanding. 
The feature I'm most proud of is the thumb notch on the handle. I haven't seen it on other paddles but I found that it really make them much more comfortable to hold.
Note the thumb notches!
You can see that the blades on the right and left had nails, which were rusted by years of horse pee, that cause a black stain -- I really like the look. I filled the holes and knot gaps with black epoxy.

I suspect all the lumber is old growth spruce but there is no doubt with the middle paddle. I tried to count the rings but had a hard time. My estimate is that, just on the handle, there are approximately 115 growth rings (plus or minus 5) within a 3" radius. I'll need to find someone with better eyes to get an exact count.
Approx. 115 growth rings  
So everything was ready for a test voyage on May 4. I took it out to Green River Reservoir, about 30 miles north of me. To be honest, I was a little nervous about whether it would float and how it would perform but it turned out to be great in every way. I'm very happy, not only in how it looks, but how it performs as well. One thing I learned pretty quickly though, is that when using it as a solo canoe, the bow and stern flip (since it is symmetrical this isn't a problem) because I need to sit closer to the center to keep the bow from tipping up too much. The paddle also worked great (I used the 68" one). I don't think I have ever used a paddle that was actually the right size for me, so it was a real revelation. I also found the large blade to provide much more power than I've ever found in a paddle before. I highly recommend making one's own paddles, in comparison to what you can buy, these are much better.   

As a final note, my wild life count for the first voyage was several mallard ducks, two loons (my first -- these are super cool birds to see and hear), a couple of kingfishers, and one beaver. Not bad for a three hour cruise.

Building A Canoe: Steps XI, XII, XIII, XIV

Part XI: Make and Install Gunwales

After finishing the fiberglass work, and cleaning up the annoying, unsightly, ridges, it was time to install the gunwales (or rails). Because the longest board of ash I could find in the lumber yard was only 12 ft, I had assumed I would have to splice two sections together. However, before I had implemented this plan, I learned of a friend of  a friend who had a 20 ft board of ash available. Luckily, I was able to use this person's shop to mill the lumber as well because there was no way I could have done it in my shop. In fact, even with a 12 ft board I was going to have to go to a friend's shop. It would have been helpful, however, if I knew the final length of the gunwales ahead of time because of the cumbersome nature of milling such long strips. I thought the curve in the canoe would result in strips longer than 16' but, it turned out, my outwales were only 15' 7" in and my inwales were 13' 7". I also milled them differently than Gil suggested. He suggested 3/4" by 3/4" for the outwales and 3/8" x 3/4" for the inwales; but I didn't see how 3/8" was wide enough to install the seat hardware, which are 1/4" carriage bolts, so I made mine 1/2" wide. With the outwales, I thought 3/4 stuck out too far so I trimmed it down to 5/8".

My first big mistake, though, was in trimming the outwales. I wanted to cut them close to the actual length because I was taking them to my shop to pre-drill and countersink the screw holes used to attach them. In lining up the outwales, I marked it from the top of the stem, and when I started to install them I realized that the canoe gets longer as you move down the stem, so it left me short to get the entire outwale covering the stem. Luckily, I had added a little to the length to make up for any small error, but it wasn't enough. I hoped that by pulling the canoe together, making it more narrow, I'd be able to squeeze another 1/2" out of my outwales, which worked well enough that in shaping the ends, it looks decent enough and maybe even mistake free.

After the shaping, they don't look too bad, and maybe even intentional
Unfortunately, I realized when I returned my canoe forms, and looked at the lender's canoes, that I didn't need to attach the outwale with screws from the outside, that the screws from the inside were enough. In my defense, in looking back at Gil's instructions, he doesn't explicitly say this and the images show the outwale being attached with screws at the stems in order to also hold the deck in place. The one hint he gives is that he says you need 65 to 70 screws, placed every 6 inches, to attach the gunwales to a 16 ft canoe and I thought his math was just bad when I realized I needed around 115. I could have just left the outwale screws in place but, in addition to the aesthetic issue, I thought it created an increase risk of rot at each of the hole openings so I filled them with walnut (and the occasional cherry) plugs. Problem solved and I think it ends up adding to the aesthetics rather than detracting. By the way, Gil recommends brass screws but my experience with them is that they are just too soft and the heads break off all the time (even with pre-drilling) so I used stainless steel. I had absolutely no problem with broken heads and I think they look just as good.

Part XII: Make and Install Yoke

For the yoke, I used a figured piece of yellow birch. I made the shoulders on it especially large, which I think works well. I had never carried a canoe on my shoulders before and the first time I lifted this one I had it resting on my neck. Big mistake. That doesn't feel too good. Better it should rest on one's shoulders, especially with a life jacket on.

Part XIII: Make and Install Decks

For the decks, I created a couple of blanks out of quartersawn ash and walnut veneer. The walnut is between each strip of ash, and as I cut and reglued the sections, I added additional pieces of veneer to create a complicated fault system (I suspect this aesthetic results from the lingering effects of many undergraduate geology classes).

Gil recommended created a cardboard template for marking out the shape of the flush deck. I highly recommend this method, it worked out well.

I didn't know how big the decks would be, so I made blanks much larger than I needed and turned the scraps in to art.

Part XIV: Make and Install Seats

Of all the aspects of my canoe, I'm most proud of the seat design (provided that it turns out to be comfortable for many hours of continuous use, which I won't know for several months). It is light weight, strong, easy to make, original, and, I think, very beautiful.

I didn't want to make a standard caned canoe seat, partly because I didn't want to be responsible for the furniture joinery and partly because I couldn't see spending 20 hours weaving it. In order to avoid that monotony, I mulled a few different ideas around for several months, including a Wendell Castle inspired sculpted seat but realized that that would be too bulky. Somehow the idea of making a bent lamination seat popped in my head, which seems perfect in strength and weight. Having never made any bent lamination work though, I needed to experiment a little to get what I wanted (of course, I could have looked on-line, but for some reason, I didn't bother, which is just as well, too many people recommend using urea-formaldehyde glue which is just too toxic for me to want to work with. Instead, I used my standard Titebond III which really is the worlds best all-around wood glue. It worked fine). For the stern seat, I glued 4 thin strips together (each about 3/32" thick) in the form. For the bow seat, because the gap is greater, I used five strips.

(this is an after-the-fact staged photo, hence, no mess or plastic keeping the form from sticking)

I wondered how many rows would be comfortable and thought that I would need three, but when I tested two, I didn't think that an additional one would have any advantage so I'm sticking with two until I'm proven wrong. I used some butternut that I bought from my neighbor when he cut down a tree in 2009. I've had it air drying in my shop ever since, which makes it perfect for a project like this because it is less brittle than kiln-dried lumber that I would have gotten at a lumber mill (maybe it doesn't make a difference but I like to think it does). They seemed to have plenty of flex in them, making them more comfortable, and they seem plenty strong too. I've stood on the front bow strip (160 lbs) without any negative consequences, so I figure two of them should be able to handle the weight of anyone getting in my canoe.

For the spacers, I played around with a scrap piece of maple and more walnut veneer. I think it is an interesting detail and it really didn't take that much time to make.

The final activity I worked on before stopping for the winter was to clean up the top edge. I had thought that a spoke shave would be the best tool for the job but it turned out that my 102 Lie-Nielsen low-angle block plane worked best (gotta love that little thing!). Now I just need to wait for spring to do some finish sanding (on the decks), touch up epoxy work (on the decks, gunwales, and seats), and then add a few coats of varnish. Until then, it is going to rest in the middle of my living room (which is fine, I don't like using my front door anyway). As is, it weights in at 66.8 lbs. Not bad considering Gil says this canoe should weight about 65 lbs and I used hardwoods that are much more dense than white or red cedar.

Building A Canoe: Steps VIII, IX, X

Part VIII - Fiberglass The Outside
After cleaning up the outside, the next step is to seal the wood with epoxy before starting the fiberglassing. I'm using West System's 105 resin and 206 slow hardener. For this size project, Gil Gilpatrick says you would need two containers of the "Group B" units, which is about a gallon container of the 105 resin. I really like West System's measuring pumps, which makes accurate dispensing so easy. The directions say that slow hardener shouldn't be used if temperatures go below 60 degrees (the directions warn about it possibly not curing at all), so it was fine for September, but I switched to the fast hardener, 205, for fiberglassing the inside, which I did in October. Actually, I found that 206 still works with night temperatures going down into the forties, it just takes longer. Anyway, the sealing process is the easiest part of the whole project, it just took a few minutes to mix up the epoxy and spread in out in a thin film over the hull.

After lightly sanding the surface, I reinforced the stems, as Gil recommends, with two layers of fiberglass on the bottom part of the stem and one layer on the front section. This is good practice for learning how to work with epoxying fiberglass. My work wasn't perfect but it can be sanded smooth enough and another layer or two of fiberglass goes over it anyway.
 Reinforced Stem
I should have taken a picture of the fiberglass before epoxying the hull. There are actually two layers on the bottom, one being an (American) football shape, the other covering the entire outside. I found the process of wetting out the fiberglass with the epoxy and getting it smooth to be very stressful because of the importance of finishing before it starts to harden. It is probably best done with two people, preferably with at least one person knowing what they are doing, but, all the same, it was doable. The biggest problem I had was in rapping the fiberglass around the stem. I ended up with a bit of a mess, partly because of inexperience but also because, when I read Gil's instructions I didn't turn the page and look at his picture, which would have clarified exactly what to do. Oh well, I figured I could clean it up with my Festool sander when it hardened, which I did. Problem solved.

It ended up taking about 3.5 hours (with a temperature of 77 degrees at 1:00 when I started) to wet-out the fiberglass (with epoxy squeegee cards) and by the time I was done, the first part had set up too much to be manipulated any more. I should have gone over the first part with a roller when I was halfway done, so the job wasn't as smooth as I would have liked.  
 Fiberglass Outside
After cleaning up the purely amerature, but passable, epoxy job, spreading out a second coat of epoxy was easy. Gil says that a third coat may be needed to fill all the fiberglass fibers, and mine were definitely not all filled, but other people I've talked with recommending using as little epoxy as possible because it adds too much weight and just looks bad the more there is. Better to clean it up and add many coats of varnish after the second layer of epoxy, so that's what I'm doing. 
 After Two Coats of Epoxy
Part IX - Clean Up The Inside
In turning the canoe over, I finally had to deal with cleaning up the inside -- not a particularly appealing task given the difficulties I had created for myself.
Start Cleaning Inside
Here is a better view of the hundreds of dowels (approximately 1500) I had sticking through the hull. I trimmed them with my dozuki (Japanese pull saw) before pulling out my Festool sander/grinder again. Because it was impossible to trim them flush, it was difficult to keep the remaining dowels from tearing up the sanding pads. Eventually, I managed to get it reasonably smooth with 40 grit paper before switching to 60 grit. After 60 grit, I started filling gaps with epoxy again, and then cleaned that up with 80 grit paper. I went over it with 120 paper before going back and rubbing it out with 100 grit by hand.
The hardest part was cleaning out the stems. I had to use chisels and coarse paper to get it reasonably clean. As long as no one is inspecting it with a flashlight, it should be good.
Unfortunately, the canoe flattened out as it rested on the saw horses without the forms. I added some support but it really didn't help much.
Part X - Fiberglass The Inside
So I put it on the ground before sealing with a first coat of epoxy. Again, pretty darn easy process. I used one of those cheap disposable Chinese brushes to get epoxy in the stems.
 Inside Sealed with Epoxy
I had to sign it before epoxying the inside and debated how to date it. I'm not sure that I'll finish this year but didn't want to pre-date it either. I decided to be optimistic and sign it 2012.

I decided I'd better pull the sides together before fiberglassing the inside for fear it would be too difficult to do after the fact. I used the forms to be sure I got the dimensions right.
I was fairly nervous about fiberglassing the inside. Gil's description made it seem pretty difficult and he ends the discussion with what I preceived to be hallow words of encouragement -- "You can do it!" I took this to mean, "I can't do it and it will look shitty" and thought it might make sense to do it in two sections that overlapped. My neighbor, who hadn't built a canoe but has plenty of fiberglass experience thought this was a good idea, but luckily I ran into a friend, who has built a canoe, the day I was going to do it and he talked me out of it -- just one piece, one time. 
It went smoother than I expected and only took 2 hours. The inside stems where much easier than the outside because Gil recommended just cutting the fiberglass short and not worrying about getting it in there.
I thought it looked pretty good when I was done and I had time to go over it several times before it set up but, unfortunately, the next morning I noticed a lot of ridges in the fiberglass. I guess I didn't pull the fabric tight enough as I was wetting it out. Oh well, again, this is what the Festool sander is for (and no, they aren't paying me to say this but I certainly wouldn't mind if they did). Of course, sanding it smooth really thinned out, or totally removed, the fiberglass in some small areas, but I'm thinking that on the inside it isn't going to make much of a difference.
Unsightly Fiberglass Ridges  
And here it is after the second coat of epoxy. It has settled a bit again. Though the width should be a little less than 35 inches, and it is about 38 here, I should be able to pull it back into shape when I add the yoke and seats. 
Fiberglassing Done!
