Carton 100mm f/13 "MD" OTA Construction - Dovetail Plate - Cut to Size and drilled
 

Completed cut and drilled dove tail plate. (Click to see an enlarged image)

 
To make the dovetail plate, I used a piece of aluminum that came from a network wiring rack I picked from items labeled as trash at my employer. The dovetail plate was cut to 3" x 12" x 0.3125" thick. A hole was drilled at both ends to attach the two Carton cradle rings and dovetail bar (not see here) using 1/4-20 stainless steel pan-head screws and countersink washers. As for the dovetail bar, it will be attached on the underside of the dovetail plate opposite the cradle rings.
