[CBCmembers] 2009 Fun at the CBC Range Day!

[Fred Call]

Hello Bill,
Wish we could join you for the range work day and race, but it's a long
drive.  However, I can offer advice for a paint mask for your targets.  I
know that some of your targets are identical to mine, and they were
patterned from the Devin B500.  The mask plate (the one with the 115 and 45
mm holes) is constructed like an "I" beam, creating a space of approximately
1/2 inch between the face of the mask plate and the back of the target face
plate.  The space between the top and bottom of the "I" beam is 6 inches,
and the overall length of the mask plate is 48".

I use a piece of 1/4"-thickcomposite board or corrugated board measuring 24"
X 5.5", but a full-length 48" board could speed the process.  This board
slides neatly between the mask plate and the target face plate to cover the
mask plate while painting the target faceThere are some welds holding the
perpendicular portions of the mask plate I together, so rounding the corners
of the paint mask board will assure that it slides easily.  .  My painting
sequence is as follows:

*Black paint first*.  With multiple targets it is best to apply all the
black, then go back to the starting point and use the white paint.  This
allows the black overspray to dry and be covered by the white paint coat.  I
begin by pushing the 5 impact plates down to the "hit" position and painting
these.  Then, with the mask plate in the prone position, paint the mask
plate through the face plate holes.

*Orange/Red/Yellow paint next.  *If needed, paint the "Offhand position
indicator" end of the mask plate with a bright indicator color.

*White paint last.*  With the mask plate in prone shooting position, insert
the mask plate cover board discussed above and go crazy with the white
paint.  This should yield a race-worthy biathlon target.

Best wishes for a great weekend,
Fred and Amy Call
Green Lake, Maine
