Default Ultra thin lines in segmented turnings...

Here's something I've been meaning to post for awhile.

Having been smitten by the stave/segmented turning bug, I've been on a quest
for creating ultra thin lines between the pieces. Formica has worked well,
but I wanted thinner (wife says I'm just never satisfied with anything!)

Walking in our local supermarket one morning, I spotted a rack with poster
board for sale at a whopping 2 for a dollar, in about a dozen different
colors. This stuff is about 1/16 thick, maybe smaller. Perhaps 80-100 lb
card stock?

Took home a few blacks, one white and one red, 2x3 feet in size.
Experimenting with white pine, I put together a small piece and low and
behold, it works! Solid as a rock. I used Elmer's Pro yellow glue for the
bonding. and lacquer for the finish. When I get around to doing a nicer
piece, I'll post pics.

Now, the white and black are perfect, while the Red (and I'll assume the
other colors as well) actually have a very small white center that subdues
the red color. So, the "red" in the line is very faint, but still there on
close examination. The card stock absorbs the glue from both sides and
literally pulls the fibers into the wood.

Contrasting CURVED lines are in the near future, and my cutting, glue-up,
prep times just got a little longer! (sigh)

As an afterthought...

Anyone ever considered taking a large stack of Newspapers, cutting pieces
into perhaps 8x8 squares, (all newsprint or all Sunday color funnies would
be interesting) gluing them together and turning a bowl or plate?

Sometimes I wish my mind had a brake pedal...



First, don't consider a brake pedal.

Second, please be aware that paper that is glued up between two wood surfaces
is an old and well-used method of splitting apart a turning. Yes, it looks
great, but it is also a weakness in your product. (I use brown paper grocery
bags) If its job is to just sit and look pretty, that is fine. If someone
decides to use this thing, it may be liable to damage.

As another poster here suggested, dye the surface (that will be glued later
in making up your woodblock) and when the project is turned, a very thin
colored line will show up. The glued (and dyed) surface is wood-to-wood, and
so will be as strong as any other glued part of your project.
