hi guys,

sorry for this thread. i tried searching the board but it looks like i can't find the exact dimension for pacemaker speed graphic. mine is the top RF by the way i'm sure crown/speed are the same. would you mind giving me the exact dimension / thinckness for the lensboard? anything i need to consider? i want to make for a few lenses (some barrel lenses) that i have.

thank you very much.

FG

Pacemaker series use the same board, within a format size, from the introduction in 1947 until the end of production in 1973.
In the 2x3 format the Century uses the same board as the Pacemaker.
In the 4x5 format the boards from 1947-1957 have 4 bumps, 2 top and 2 bottom for the slide locks. The boards from 1958-1973 have 8 bumps, 2 small top, 2 small bottom for Pacemakers; 2 large left and 2 large right for Super Graphics.
The corners are rounded on all boards. The boards are made from .049 inch aluminum.
Left - right = 3.710
Top - bottom = 3.648
small bump - .210
large bump - .241
front edge to base of lip , no bump - .20
Inside left - right = 3.612
Inside top - bottom = 3.550
Top left - bottom right = 5.041 outside; 4.938 inside.
