After finally getting on with my idea of putting a small Chinese-made circuit board in my Super Graphic to kick the voltage up, I find myself disappointed at the project. So I have another idea. How about putting a regular low-voltage solenoid from a Speed or Crown in place of the 45V one in the Super? I got out my dial caliper and it certainly looks doable. The Crown/Speed solenoid is actually a hair smaller in diameter than the Super one, except at the base, where the plug goes in. It's slightly bigger there than the diameter of the Super's solenoid. But I also notice the solenoid on the Super has a wee bit of wiggle room. And if that isn't quite enough, there's plenty of soft metal in the frame that could be wallowed out a hair, with no harm done.
And the Super's battery bay certainly has room for at least 4 or more AAA batteries. So first a question--just exactly what is the correct voltage of the Speed Graphic solenoid? Is it 3V or 4.5, or either? And what voltage would I end up running that battery power through the normal circuit in the Super Graphic? Attached is the circuit of the super Graphic. Does anybody see something wrong with my idea that I'm not getting? Thank you. PS attached also is a photo of the Super Graphic solenoid in it's correct position.
