The printer was indeed made by Omega/Arkay but do you really want to use such a beast??? There are issues with burning and dodging with such a printer (under/over coverage). I don't know of anyone using these printers for contacts but I do know a lot who use the plain wooden-hinged frames with a single bulb - far better control. As for buiding one, I reallly wouldn't waste my time as these can be had fairly cheaply.

Anyhow, good luck with it if you do choose to go that route.
