Drue Hogland – Square Bowl By John Torchick

The demonstration for this meeting was done by Drue Hogland, Knoxville, Tennessee. Drue chose turning a square bowl for the meeting. (Let me insert something here. My wife asked, “How do you turn a square bowl?” I said I would find out this evening.)

Drue began by showing a piece of wood that was a cube in dimensions. There were two pieces on either side of a waste block of about ¾ inch. He drew a sketch of how the pieces were glued- each glue joint included a piece of brown paper and glued in place with wood glue as Titebond oar Elmer’s glue. The layers were- wood block for the bowl, paper and glue, waste block, paper and glue, wood for a second bowl. He stated that CA glue wouldn’t work as it won’t “move.” Drue reminded us that this would entail turning both side grain and end grain. He showed us that the waste block was marked in the center of each side. He mounted the wood on the lathe and turned it down to the waste block on each side. He used a

From the Editor: We all owe a big THANK YOU to Woodcraft for hosting the July DAWG meeting. Be sure to thank them when you visit them, and be sure to visit them. Thank them for the food, the discounts to DAWG members, and for making room for us use their shop for our meeting. THANK YOU! I also want to thank John Torchick for his write-up of the meeting and his description of Drue Hogland’s demo for this newsletter. There is not a lot to report on this month. The DAWG board has taken a couple of months off, but will be meeting the first Thursday of Sept. It is time to begin making plans for 2019. I will have a little more to say about that at the meeting on Tuesday. ●

Drue Hogland… bowl gouge instead of a roughing gouge for turning to round. Next, he cut grooves at random with a pyramid point tool and followed up with a light brushing to eliminate any “fuzzies” that remain.

Drue then parted the pieces for the next step in turning each individual bowl. Each piece was mounted on Cole jaws and a small hole for a screw chuck was drilled with a Forstner bit. The piece was mounted on the screw chuck and trued up with sandpaper glued to a 2X2. The inside of the bowl was then cut into the piece. One could make the bowl as wide and as deep as you wanted as long as you didn’t hit the end of the screw chuck! The pyramid pointed tool was used again to put a series of grooves in the face of the piece. The piece was lightly sanded, and the wire brush used to remove any “fuzzies” left on the surface. The bowl was then mounted in Cole jaws and the hole in the bottom was enlarged with another Forstner bit. A plug was glued in place and turned to look like a foot on the bottom. Drue said he used a base coat of paint and a top coat of milk paint which doesn’t penetrate much. A top coat of lacquer is applied to complete the square bowl. ●

DAWG Meeting, July 24, 2018 Meeting called to order by president, Jared Bruckner. Pledge of Allegiance was led by Jared Bruckner. Visitor- Dennis Schreiner. Thanks was expressed to Woodcraft, Chattanooga, for hosting the meeting and demonstration. Also, Woodcraft offered discounts for purchases and selected items for that evening. Concerns were expressed for member who were experiencing some health issues. Dieter Kuberg will be having two more eye surgeries. Bert Workman is over chemo treatment and will be having surgery on his arm soon. This might entail some more chemo. The Bring Back Box was awarded to James Ridley. Aletha Browder had two items in the BBB. She had turned an attractive jar lid with a contrasting knob. The jar was filled with cookies! She also turned an ornament from a banksia pod. Show & Tell had several items in display. Charles Jennings displayed a pepper mill, an ice cream spade (very important item in any kitchen!), and a pedestal cake plate. Jared Bruckner displayed an attractive plate that he said was turned a bit too thin. It was well made and, by holding it up to the light, it was evident that the wood was turned thin. It might be a challenge to see if one can turn something paper thin. Rick Urban handed out sheets outlining the organization, Artists for Empty Bowls. He has registration forms and three sacks where the forms could be placed as to how we as individuals could be involved. ●

Wood Identification

I had always liked to work with wood, but before I retired I had little time to spend with wood. After retiring and started to learn to turn my teaching instincts made me want to do demonstrations. But, I was just a beginning turner, and was not ready to teach turning, especially to people that had been turning much much longer than I had. Then I had an idea. Why not study about how to identify wood and prepare a talk on wood identification.

I knew some about identifying trees, but not much about identifying wood, especially when one only had the wood and knew nothing about the tree it came from. So I started looking for information about wood identification and in 2011 came upon a book by R. Bruce Hoadley: Identifying Wood – Accurate results with simple tools. This by far the best book on wood identification that I know of, and I have ten books on this subject!

Hoadley states in the introduction: The equipment Hoadley suggests is merely a 10-power hand lens and a single-edged razor blade! Although he further states: “In some woods, however, identification requires examination of individual cells or even details of cell walls, which requires the much higher magnification provided by a microscope.”

One would not have to read this book from front to back, but I think it would be best since the beginning chapters give information that one needs to understand before reading later chapters. It is like most textbooks in that respect.

One criteria that I use when evaluating books is to ask: Has the book been useful to me in a practical way? Even though it does not keep me from making mistakes, such as identifying Bradford pear as Osage orange, it has been useful. Recently I need to positively identify some wood I was going to turn. I had several pieces for wood that I had gotten from Florida, and I thought that I had picked out a piece of Mango, but I was not really sure. I remember that Hoadley had a section on wood identification using fluorescence under “black light.” Looking the table he gave I noted that Mango gave off a Pale orange glow under “black light.” So off to Amazon to buy an inexpensive “black light” source and two days later I was able to positively identify the piece I had turned as being Mango!

So you may be wondering why you have not heard me give a talk on wood identification. Well, I wanted to be able to make some pictures for my planned talk, but was unable to properly calibrate the digital microscope I bought to show picture that I took at 10X magnification. But, recently I found what I think was needed to do the calibration. So be warned, a talk on wood identification may be coming in the future. ● Hoadley, R. B. (1999).

Turning Pages A book review – Jared Bruckner

The purpose of this book is … to answer the question “What kind of wood is that?” It is written for the beginner and attempts to provide a self-taught approach. It requires no prior experience either with wood itself or with the procedures and equipment used its identification.

Wood Talk By Lloyd Speer

Black Oak The Oaks are in the Beech Family with about 400 species worldwide, but only 69 are native to North America. Most are deciduous, but a few species in warmer climates are evergreen. Native oaks can be subdivided into three groups—the red oaks, the white oaks, and the golden-cup oaks (found in California and the Southwest). All oaks have acorns and buds clustered at twig tips. Oaks have a fairly coarse grain with medium-large pores. The wood is easy to glue and takes stain and finishes very well. It is commonly used in cabinetry, furniture, interior trim, flooring, and veneer. The Black Oak (also called Eastern Black Oak) is a member of the red oak group. It can grow to heights of 65-80 feet and with trunks 3-5 feet in diameter. Black Oak wood has a light to medium reddish-brown color, but there can be some variation. It should not be confused with Bog Oak (which is actually black in color). The bark of older Black Oak trees is nearly black, while the inner bark is yellow. In the early days of our country (and again during World War I when foreign dyes were difficult to obtain), the inner bark was prized because of its dye properties for cloth. When full grown, the leaves are dark, glossy green above, paler beneath, with conspicuous brown hairs where the principal veins branch. They tend to vary greatly in size and shape, measuring from five to ten inches long and from three to eight inches wide. They may be either shallowly or deeply lobed, and are always bristle-tipped. Sun leaves from the canopy tend to be smaller and more deeply lobed than shaded leaves. The light brown acorns are from one-half to three-quarters enclosed in the thin, dark red-brown, scaly cup. The yellowish kernel is extremely bitter. The average dried weight is 45 lbs/ft3, with a specific gravity (Basic, 12% MC) of .56, .71. The Janka hardness is 1,210 lb. Crushing strength is 6,450 lbf/in2 (44.5 MPa) with a shrinkage of Radial: 4.4%, Tangential: 11.1%, Volumetric: 15.1%, and T/R Ratio: 2.5.
