<DIV><FONT face=Arial size=2>A long time ago Barry Lloyd and I took a
machined straight edge and visited the scrap yard of our local tombstone
supplier. They allowed us to search through the sides that they cut from the
original blocks of material. According to them all the sides are
absolutely true.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Not the case. So we checked the scrap
pieces,and marked out the areas that were flat and true. Took some
searching. Then they cut the unwanted material off and we had two
pieces of 18" x 36" true stone (marble?) The pieces varied in depth
from 1 to 2" because of the rough side. We then made a proper size fence
on a piece of presswood,poured in some quikcrete,set the stone in this, smooth
side up and viola! A true and heavy building board.</FONT></DIV>

<DIV><FONT face=Arial size=2>A good thing wings were smaller then.
Colin saw our work and thought it a great idea,so he trooped off to equip his
workshop properly. Mine and Barry's still in use today after more
than 25 years. I thing Colin built a foamy on his recently???</FONT></DIV>

<DIV><FONT face=Arial size=2>For today's bigger wings,I use a piece of 1/4 plate
glass on top of the stone,suitably braced where it overhangs at the wing root
position.</FONT></DIV>
