Mystery Wooden Object

Straight off I should say that I love a mystery. Puzzles and riddles too. I especially like them when they are connected to real objects. I�m not sure why. Maybe it is a quest for small truths. Or just intellectual curiosity. Maybe it is wanting to discover the secret clues to how each small part of the story fits together as the whole.


Or maybe � wait, I think I am doing it now � the mystery of the mysteries! Aaagh! Well, I guess I do fit my sometime nickname of �Mr. Theory�.


Anyway � here�s one I have been thinking about. If you like this kind of thing then enjoy � and feel free to speculate or poke holes in my theory. If you don�t � well, it�ll probably bore you to tears and you might want to stop now � but take a look anyway, because maybe you have some ideas about this�


Item: Mystery Wooden Thing


Known History: Not much. The woman at the store didn�t know anything about it, but said she bought it because she really liked how it looked and felt in her hand. I agreed and ponied up.


Front View: (Hand included for scale�)



Rear View:



Side View:



Detail View of Bracket:



Features I�ve noticed:


Faceted, rather than true curve on outside.
Thickness varies somewhat � not uniform.
Strange square insert in back � could be cut off tenon or just a patch.
Bracket opening at bottom (just feels like bottom�) shows wear pattern on inside.
Besides rosette, there are fainter decorative lines carved on the bracket.


Assumptions:

It had a purpose. Seems overly complex to just be a �doodle�.
It was handmade. Way too much character for anything else.
Something went through that bracket � a cord maybe? Functions like a pulley?


Ponders:

Why the square mortice? Wouldn�t boring a round mortice be faster? I can think of two reasons. First, if this was used as some sort of pulley it would need to resist pivoting back and forth from the friction of the cord being pulled through it. Square mortice and tenon clearly better here. Second, maybe he/she didn�t have an auger big enough, or even a brace. Could this thing be entirely carved with a knife?


One of a kind, or a lone wanderer from a set?


What type of wood is it?


Theory:


Okay, time to take a crack at it.


Here�s what I think: It is a pulley or bracket that was hung on the wall by way of the square mortice, now plugged by the tenon cut off when it was salvaged, and it�s use was somehow connected to window treatments. Handmade by the owner.


Theory Weaknesses:


Tons. Primarily, that the �cut off tenon� is very smooth and has similar surface quality to rest of piece � does not look like a recent salvage job�


Conclusion:


I don�t know what it is but I think it is a great example of how form might follow function, yet is not tied to it. I don�t know the function, but I really appreciate and love the form. Someone put a lot of time and energy into making this, and I love it for its form alone � I just wish I knew more about it. Any ideas?

Plane-On-A-Stick

Well, blogging continues to take a backseat to the ongoing bamboo floor project. I cannot believe how time consuming it is! My only consolation is that it sure looks great! But man-o-man, slow, slow, s-l-o-w! Glad I didn�t really know about this ahead of time � I never would have started�


One unexpected bright spot was actually getting to use my Stanley #70. This did not start out as a good thing � it�s amazing what a carpet and pad can hide. The plywood sub-floor was all over the map in terms of flat and smooth. I spent a lot more time fixing it than I anticipated � �I�ll just tear this carpet up and put down the bamboo. Simple.� Yeah, right. Anyway, some high spots were okay after screwing them down tight, but some were not. A few sheets of the plywood were thicker than the others (Apparent motto of the original construction guys: �Can�t see it from my house!�) and the abrupt edge had to be eased into a wide bevel that the flooring could cope with. Enter the #70 � �Plane-On-A-Stick!�


I had bought this years ago. Didn�t really need it, other than some vague idea it might be usable for Windsor chair seats. But it was in great shape at a good price, and it looked lonely and unloved. It has been sitting on the shelf in the shop waiting to get in the game, and now its day had come. And what a champ! Worked perfectly! Almost made the flooring job fun. Almost.



The plane end rotates, and can be used both pulling and pushing.




Cool! But after this job is done, it�s back to the shelf for a long while. The bamboo for the kitchen floor is on hold whilst I rebuild my depleted store of motivation and a team of chiropractors and physical therapists straighten my back.

Milk Paint

Just some thoughts, comments and advice on using milk paint based on my (limited) experience so far:


I have only worked with Real Milk Paint � I love their products (look at their Soy-Gel Stripper and Citrus Solvent too) but there are other companies out there�


I highly recommend the Anti-Foaming agent. With our water, things ended up more like milk paint mousse until I started using this stuff.


I like using quart sized, wide-mouth mason jars for mixing and storing the paint.


If you just mix the powder and the water by shaking, you get a much more textured (gritty) paint that has a very interesting look, but will need some work (rubbing down).


If you use some kind of blender/mixer (I use a mixing wand � corded no less! I am so ashamed�) you get a very smooth and even paint.


Remember to stir the paint often as you use it � there tends to be a subtle shift in the color/consistency as you use it up. I probably extenuate the situation by always trying to mix up �just enough� to get by � sort of like Kramer and the fuel light.


It dries fast! You can do a second coat or top coat with oil/wax in about 3 hours! Love it!


Non-toxic! Yes!


Low, low odor! Sort of a pleasing wet cement-ish smell to my nose�


Normal mix 1:1 (powder:water) for opaque (two coats) or 1:2 for a wash.


Very easy to mix colors to create new hues.


Get the Color Sticks - way better than the computer monitor for judging final results.


Keeps in the fridge for a good while.


Cleans up with good old water!


Dries FLAT! Which some people find attractive � but I like it much better after the oil/wax hits it.


I usually make a test board or two and play around with the paint and oil combos. Sometimes I like the Tried and True Danish Oil (cradle) and sometimes I prefer the look of the Dark Tung Oil that Real Milk Paint also sells. On the latest project (chest) I just went with my own mineral oil/beeswax mix � also looked great.


Here�s a (totally staged) shot of my paint kit:

Simple Chest

Well the storage chest for the shop is finished � and tomorrow it�s back to work on the bamboo floor. This was a fun project � if not as short and quick as intended.


First, I jointed the 1x10�s and glued up the width I needed. I always try to pay attention to grain matching, but as I knew this was going to get the milk paint treatment, I didn�t worry too much about it (fairly obvious from the picture). After cutting the parts to length, I smoothed them � again, not being too particular. On all non-face sides, I just wanted to clean-up the glue line and make the panel tolerably flat. These sides just got hit with the jack plane. Faces received a follow-up with a smoother (#3, #4 or #4 � depending on the wood and my mood�).



As this was not a fancy chest, the joinery was my favorite simple choice � rabbeted butt joints. These I cut with my Record 778, which I prefer to the Stanley 78, owing to its larger and more stable fence. It did have two problems, one of which I fixed and one I fudged.


The fix was sharpening the cross-grain spur correctly. I don�t know what I was thinking when I sharpened the first of the three spurs sometime in the past. I sharpened the wrong side! More correctly, I sharpened both sides - which of course meant that the spur was no longer flush with the side of the plane/blade. The result was a very rough shoulder with a lot of tear-out. Stupid mistake � easy solution: sharpen another of the spurs the right way. No sweat � clamped it in the Vise-Grips and after a short trip to the Scary Sharp� bench it was ready to go.


The fudge was remembering to account for the odd angle of the inside face of the fence when I was setting the fence for the width of the rabbet. For some reason, the fence face isn�t perfectly perpendicular to the sole of the plane, it leans in a bit. So if I set my rule flat on the plane�s sole and measure over to the fence from the edge of the blade, everything looks fine, but the rabbet will be cut too narrow when the bottom edge of the fence contacts the stock first. Stupid problem � easy solution: hold the rule on edge so that it contacts both the blade, and the closer lower edge of the fence. Just have to remember to do this every time, until I really fix it by adding a wooden face on the fence and adjusting it to perpendicular. Another day.




If you are a sharp-eyed, detail person, you probably caught my stupid lay-out mistake in the last picture. Yep, I wasn�t paying attention and ended up having to cut the rabbet right through a knot. Here�s a closer look at how I was saved by a very sharp blade�



After the rabbets, it was assembly time � clamps, dry-run, glue-up, blah, blah, nails (What? You got a problem with that?), adding the plinth and lid edging, filling the nail holes, blah, blah, planing, hinge mortises (just knifed them) blah, blah, blah and it was done.



Time to paint. Have I mentioned that I love milk paint? I do! A quick wash coat of yellow ocher and then a rub-down with wax. I make my own concoction of mineral oil and bee�s wax. Simple to make, use and it smells great! And of course, non-toxic.


I love how the look and feel of the painted wood changes when the oil/wax is rubbed in.






I was kind of going for a Shaker look and I think I got it pretty close. I think it will improve with time or maybe I'll just stop focusing on all the mistakes I know are there...

Sticking Board

Well, I squeezed in a little shop time during a lull in the ongoing "War of the Bamboo Floor" � a war in which I am forced to admit defeat. Well, at least defeat of my anticipated schedule. And schedule Plan B. And Plan C. Utter, utter defeat.

But my time in the shop was much more successful and enjoyable. I�ve been trying to create more storage space � particularly for some items I don�t like looking at. So I decided to make a simple chest to hide them. I had it started and rolling along smartly � until the floor project exploded. The next stage of the chest was making some mouldings to spiff-up the base or plinth.

I pulled my long dormant sticking board out of its corner and got to work. My sticking board is very similar to Chris Schwarz�s board � I don�t remember basing it on his, but it is so similar that I probably did after reading his blog (he posted about it around 1 year ago�).



The board is just a 2x6 with a 1x2 screwed to one edge (jointed straight first of course). Two sheet rock screws with sharpened heads are the stops � they can be raised or lowered as needed. The whole board is held in place by trapping it between a bench dog and the vice dog in the end vise.


For this moulding, I needed � by � sticks and I had some likely volunteers in the scrap bin, but they needed to be cleaned up and sized correctly first. I was about to reach for the marking gauge when I realized that I had a perfect jig sitting right in front of me! I just put the oversized stick on the sticking board, grabbed a #5 jack and planed down until the strip was flush with the sticking board fence. Very simple, no layout or extra steps. I just had to remember to rotate the stick before it reached its final size if I wanted to clean up additional faces � once it was sized in one dimension it was too late to work on the opposite face. Doh!

After the sticks were the right size, it was time for the molding plane. This is a 5/8 ovolo made by Brown & Barnard (British) somewhere about 150 � 200 years ago. I love putting old tools like this back to work!

Like a lot of moulding planes, this one is �sprung�, which means it is tilted over at an angle in use (the spring lines on the toe of the plane guide you with this). This spring makes the blade profile much easier to shape and allows for the mouth of the plane to remain tight. (There is a great web page out there somewhere that explains this with pictures � I�ll post a link if I can find it again.)

One of the great things about using old tools, is that they can teach you old ways of working. This old plane was about to teach me another reason for springing a plane. The plane has two stops � one lateral, which I have always thought of as a fence, and one for depth. The problem I have always had with this plane is that the �fence� is very tiny, and I have struggled to keep it aligned while planing. I kept thinking �Why did they make it this way?� and �Wouldn�t a larger fence be better?� The break-through came when I changed my assumptions and thought of the fence as a stop. Rather than starting with the �fence� riding on the wood, I tried starting with the curved section of the blade on the corner, or arris, of the wood (I tried to show the difference in the next two photos - click on them for larger images). Wow! Faster and much, much easier! The plane cuts directly in along the spring angle until both stops engage and that�s it. I didn�t have to mess with both holding the spring angle and also applying pressure vertically � I just sprung the plane and applied pressure at that angle. Very cool.





Once I had enough moulding cut (or stuck), it was time to miter it and apply it to the chest plinth. I was about to put the sticking board away and get out the miter box when inspiration struck again! (Twice in one day? What gives?) Why not just modify the sticking board fence and turn it into a miter box? Five minutes later, success!


(Oops! Uncle Henry has a tree growing out of his head! The thin strip of wood sticking out perpendicular to the fence in the photo above is a planing stop on the bench in the background � it has nothing to do with the sticking board�Funny how the human eye and the camera see things differently�)

Hopefully, this chest will be finished soon � but the floor war awaits�

Bench Leveler Feet

The floor of my shop (garage) is sloped towards a central drain, which creates some interesting leveling problems. A couple of years ago, I decided that my system of using shims to level my bench just wasn�t cutting it. Too much moving around and re-leveling. What I wanted was some system of leveler feet that would be easy to adjust and have good grip. All the locally available options where doubtful � either way too wimpy or too slippery looking. I decided to try to figure out how to make some.


After digging around online I found this article by Angelo at WoodCentral:

http://www.woodcentral.com/cgi-bin/readarticle.pl?dir=jigs&file=articles_374.shtml

Thanks Angelo! I liked the beefiness factor and it sure seemed like it would grab the floor and not slide around. I decided to make my own, but as always I followed my motto: �Why leave well enough alone, when you can mess with it!� Now, this usually results in my making things way too complicated and much longer to finish � sort of like my infamous driving �shortcuts� (which, bowing to pressure from more time-oriented observers, I have renamed �super secret back ways�). However, in this case, I think I actually improved on the design � at least for me.


The first major divergence from Angelo�s design was not drilling all the way through the puck. In the comment by Bob included at the end of article, he mentions his idea of just drilling a hole deep enough to seat the head of the bolt. I liked how this left more �meat� to support the weight of the bench, and I didn�t mind the puck not being firmly attached to the bolt.

The second change simplified how the bolt attached to the bench. I decided to see how things worked if I just fit the bolt into a snug hole in the bench foot rather than screwing into an inset coupler. Mostly this was because I didn�t feel like flipping the bench over to bore a larger hole and I already had �� holes in the bottom of the sled feet from the existing wooden shoe.


This necessitated the third change; leveling the bench with jam nuts and a washer rather than with the bolt/coupler. Basically, as seen in the photo, the washer supports the bench and is adjusted by tightening or loosening the nut directly below it. This nut in turn is locked in place by jamming it with the second nut. Very simple. The foot does not need to rotate and remains steady during leveling operations. (Side note: I used standard hex blots rather than carriage bolts � I don�t know if it makes much difference, but I suppose the smooth head of the carriage bolt might just rotate in the puck as you tried to lift the bench by tightening the top bolt�)


I have been using this system on my bench for almost two years now and it has been great! I think I have had to reposition the bench once in all that time � as opposed to daily with the old slippery shim system. And I have never had to adjust the level after the initial setup � jam nuts rule! Eventually, I will be replacing my bench (this is the first one I have made, and despite continually showcasing my lack of skills, it has served admirably) and I will definitely be using this same system � unless I can �improve� it again, because �Why leave well enough alone��

Saw Bench

Sometimes, when we struggle with learning something new (or in this case, something old), we are missing a key piece of the puzzle � some doors are hard to open, but they are surely easier to open when they are unlocked!

When I was first trying to learn how to use handsaws, I struggled. Even with a properly sharpened saw (and that was really more of a mental block � it�s not that hard to sharpen a passable saw, but you have to be willing to try!) I struggled to cut to a line. It was very frustrating � one quick cut, followed by a lot of fussing with a plane to try to square up the cut. I was missing something � I just didn�t know what.

Off to the books! In Alex Bealer�s Old Ways of Working Wood I found a sketch of a saw bench. It took me a while to find this, as it was in the �bench� chapter and I was of course looking in the �sawing� chapter, as I had no idea that a bench was the key. Slowly it dawned on me, the workbench that I had so painstakingly made, the centerpiece of my shop, was not going to be able to help me saw better. In fact, it was working against me. With a board in the vice, my posture and the angle of the saw to the cut were wrong (at least for a beginner�). I decided to make my own version of the saw bench I had found in Bealer�s book.

The saw bench I made is sized to me � the perfect height for my knee to hold the stock being cut. This brings my whole body into position�

Click. The door was unlocked! The very first time I used it, my results improved a hundred fold. Soon I was cutting to the line � or even splitting the line, with no planing required (unless I wanted smoother end grain). I found this very, very exciting! It wasn�t, and still isn�t, magic. I need to slow down and pay attention to what my brain, my body, and more importantly, the saw are telling me. But, it was the key I needed. I suppose I may have stuck with it; continued struggling and slowly getting better without the saw bench, but I�m not sure I would have, and I�m glad I didn�t need to.



The two primary duties of the saw bench: ripping and crosscutting.

Ripping: The length to be ripped off hangs over the right side of the bench as I am right handed. If it is a short rip, I stand at the end of the bench with my right leg on the floor and my left knee bearing on the board. If it is a longer rip, I either stand with my left foot on the floor to the left of the bench and rest my right knee on the board, or I climb up on the bench and kneel on the board with both knees. On occasion, I use the long ripping slot down the center of the bench � usually when the stock is very thin and needs more support.



Crosscutting: I stand beside the bench at the right end, and the board to be crosscut projects beyond the end of the bench by the amount that needs cutting. I line up the far edge of the board with the long edge of the bench which gives me a stronger visual sense of squareness.



Once I had the bench, many other uses became apparent. Chief among these is the bench is where I do the majority of my boring work. Working with the brace lower allows me to get over the work and increases efficiency and efficacy. And again, my knee becomes the clamp, unless I choose to straddle the work, in which case my rear becomes the clamp. It also works with its larger cousin to support panels or other larger pieces when I need to plane their edges. Additionally, the saw bench gets pressed into service for assembly purposes � at which time the added convenience of the saw bench having the same height as the seat of my shavehorse really pays off.



What other keys await?
