I saw David do something on a recent show that seems real trivial
until I realized that I didn't do it.
He was bringing a line around a rectangular piece of stock using a
tri-square to transfer tyhe line from one surface to the next. Rather
than trying to line up the tri-square edge on the edge he was
transferring, he put his pencil point on the line, then slid his
tri-square to that point. Yeah, I know it's trivial but I've done that
transferring around a rectangle many times and usually wind up on the
4th side 1/16 or greater than where I started. Using his method, It
his right on the money.For what it's worth.
Something else I was taught was not to wrap the line all the way around in
one direction. Go part way around one way and the rest of the way the other
way around. It prevents any errors from building more than necessary.
Ahhh - Another draftsman and all the baggage that comes with it (good and
bad). I learned the trade at Pittsburg State Univ (Ks) in the late 60's
then went on to do aircraft and airframe design for several years. I still
use a lot of drafting practices in my wood project designs and layouts.
After years of doing aircraft design, my mind thinks in hundreds and
thousandths and I find myself constantly converting from decimal to
fractional equivalents - easier to do the math.
I know what you mean. I was a graphic artist who worked exclusively in hand
ruling (in ink) of business forms. I can work/convert/divide in points,
picas, 1/16ths & 1/8ths, tenths and 5/32nds in my head. Computers took over,
but the skill helps out in woodworking and other jobs.
PS. One trick I picked up many years (decades) ago: Do you have problems
keeping a sharp point on your pencil when drawing guide lines on your wood
or drafting. When drawing the line don't keep your pencil vertical, keep it
at an angle somewhere between 60, 45 or 30 degrees above where you are
drawing the line and twirl the pencil as you draw the line. This way the
wear is spread all around the lead and keeps the point sharper and the
resulting line finer, much longer. It is a trick that is easy to use and
They now also have a saddle dovetail marking gauge.
If you use a marking knife rather than a pencil for layout
you can drop the knife into a scribed line at a corner,
move you're square to it and cut the next line.
