Kodak Ektar 203 lens size help

[gerryroberts]

I have just purchase a Kodak Ektar 203 lens, and ready to order a lens board from Mid-West Camera. The lens board is for a Pacemaker Crown Graphic. I need to know the size of the board for this lens. Mid-West is not sure. Does anyone knows off hand the size of the board?

Thanks

What size is your Crown Graphic? If 23 you need 2 1/2 x 2 1/2; if 34 you need 3 3/16 x 3 19/64; if 45 you need 3 23/32 x 3 21/32.

I'm sorry. I have a 4 X 5 Pacemaker Crown Graphic. I need the size of the drilled hole in the lens board.

Thanks

Gerry - The hole size in my board is 1 & 3/8 inches. My 203 Ektar is mounted in a Kodak Flash Supermatic shutter with a top speed of 1/400 sec. If yours is in a different shutter, the hole size may be different. 1 & 3/8" hole gives just a little "wiggle room" for the shutter; about 1/32". If you need a more accurate measurement, let me know and I'll scare up a micrometer.

I have the same setup and was able to make a wooden lensboard for my Korona with a paddle bit from Sears.

If I remember correctly, my 203mm ektar in supermatic shutter fits nicely in copal #0 hole.

I was able to find this discussion about the shutters that different versions of the 203 Ektar fit.

My Ektar 203mm is in a Compur shutter and fits in a Copal #1 hole.

Thanks for all your help. I have a Synchro-Compur sutter and I have taken the mesaurment of roughly 1 9/16 inches. I think a Copal #1 would work since Scott has the same one.
