Bill Of Materials:
One Piece Of Maple 3/4" By 1 1/2" By 6 "
One Piece of Maple .218" by .265" by 4 5/8".
Five Pieces Of Maple 1/4" By 3/8" By 1 1/2"
Ten 6-32 Phillips Head Machine Screws By 1 1/16"
Ten # 6 Flat Washers
Ten 6-32 T- Nuts

Take the block of maple that will be the body of the fixture.
It should be 3/4" by 1 1/2" by 6".  The closer to actual 
dimension you make it, the better the results. I am talking .750" 
by 1.500" by 6.00".

Place it in a vise on your milling machine. Put two parallels under 
our work block.  Now, slowly tighten up on your block. Gently tap 
down on the block until the parallels do not move.

Now, we are ready to locate and orient your work to the machine's axis. 
There are three. X,Y, and Z.
X is the movement of the long table to the left or to the right.
Y is the movement of the saddle forward and backward.
Z is the movement vertically of the head carrying the spindle

Pick up the two reference edges X and Y.  Make a note of the numbers. 
Move the table 1.00" along the X axis.Move the saddle .375"along the 
Y axis.  Always move in the same direction to take up the backlash. 
This intersection will be the location of the first hole.  Center 
drill and drill a clearance hole through the block.Use a #28 drill
(.140"Dia.).  Now counter-bore the hole for the barrel of the T-nut.

Use a #20 drill (.161"Dia.)drilled .187" deep. 

This will be a typical procedure for the remaining nine holes.
Follow the drawing  and location chart for the rest of the holes. 
That will  be the bottom of the block.The recesses for the Port 
Lid Posts will be milled in next. For clarification,I will supply 
a dimensional chart, and drawing. The recesses are for the Port Lid 
Posts,# 96 Corel Victory SM23.they are 10 mm square (.394"). There 
will be five at 1.00" intervals, and centered on the holes drilled 
for the clamp screws. 
 
Connected to the recesses are five slots.  The slots are.250" wide 
by .125" deep, same depth as  the recesses.  The slots will provide 
a guide for  the adjustment blocks. The slots go from the back edge 
of the main block and become an integral part of the 10 MM square 
recesses.  The clamp strap will have five holed drilled through it. 
They are central to the .265" width and go through the .218" 
thickness.  
 
The holes start .312" from one end and are 1.00" center to center. 
There are five adjusting blocks to be fitted into the .250" slots 
milled into the main block.The adjusting block has a slot milled 
through it central to the .250 width. The slot starts .375" from one 
end of the adjusting block and is .250" long.  At the front of the 
adjusting block is a glue relief cutout.  This is .125" high by .078"
deep.  This will be shown in the drawing of the adjusting  block.
