I have a double convertable Schneider lens that I would like to use filters on t he copal #1 shutter when the front component is removed. Is the front thread on a copal #1 a standard filter size? It seems to be about 39 or 40 mm.

I use a yellow filter when the front component of my Wollensak triple converble is removed but rather than trying to find a screw in filter that would fit (none of the filters I had on hand would fit so I figured it was an oddball size) I hold a Lee 4" x 4" yellow filter over the front of the shutter. It isn't very elegant but it seems to work fine - at least I haven't yet gotten my hand in the picture. If you don't care to do this, and if you don't get an answer here, I'd check with Steve Grimes.

Before you criticize someone, walk a mile in their shoes. That way when you do criticize them you'll be
a mile away and you'll have their shoes.
Charles, I just purchased an adapter ring from Schnieder that allows me to use lenses with a 39mm thread on the front of a Copal #1. Seems as though that should do the trick for you. By the way, Schneider is very proud of those, they are not inexpensive. Steve
Front lens thread for a Copal #1 shutter is M39X0.75, An adapter to allow a more standard sized filter such as 46, 49, or 52mm is a special made item which I can make and costs $50.00 See www.skgrimes.com for more info about this.
