I
was asked to build a ramped shooting board for client in the USA, so
I built two to choose from. 
Both
boards use Jarrah as the primary wood and Tasmanian Oak as the
secondary wood.
These boards have a few small improvements
over previous ramped shooting boards. The fence continues with
micro-adjustability, but now it also has a sliding secondary fence
that may be used when worn. The rear of the fence is no longer square
but rounded to prevent breakout.
The
ramp angle is 4 degrees.
Here is board #1: 
And
a close up of the fence. Not the adjustment knob in Elm. 
Board
#2: 
And
its fence: 
A
close up of the rounded section of the fence: 
And
what happens when the fence is square: 
There
is a mitre fence for each. 
The mitre fence is attached at the rear with a bolt. Standard hex key needed - same as for square fence sub fence.
This method allows you to use the fine adjustment on the mitre fence as well as the main fence.
Why
microadjustability and not a fixed fence? The adjustment allows not
only for fine tuning of the fence, which is necessary after the board
becomes worn and is re-planed, but it also permits one to do away
with shims. The adjustment is 1/8" each way.
The
breakdown ...
Close
up of fixed side. Note that this fit is very tight. There is no play
at all. I cut a groove for a bladed screwdriver so that the bolt may
be inserted and removed.
Close
up of the adjustable side. Note that there is 1/8" movement to
front and rear.
All
bolts are held by nuts recessed and epoxied in place on the other
side.
And
a breakdown of making the adjustment knob prior to shaping with
rasps.
For recognition, I added an Australian $1 coin (I think that they are bronze). It is dated 2008.

last picture. I always wanted to post this .. a shooting board
