broke the red plastic, cam-shaped red slide for my rolleimatic enlarger. Can't remember what it is called but it allows me to focus without exposing my image. I anticipate that finding a replacement will be extremely difficult so I would like to cut out a new one.
Question: is the red slide just lexan? acrylic? What would be suitable to use for an enlarger? And if possible, sources? In canada???

I never got into the habit of using the red filter. Depending on the type of paper you use, it could fog the paper; definately if you use color paper. Unless you are using a very thick base paper, it shouldn't make much difference if you focus directly onto the easel. If you are concerned about the focus being different due to the thickness of the paper, focus on the backside of an old piece of the same thickness paper.
If you are really set on replacing the filter, the material is not so important as the color or the optical quality. It must be of a particular color so that it doesn't fog the paper, and it should be of an optical quality that it won't distort the image.

Some multigrade or polycontrast under the lens kits also have a red filter, or you could use a dark red camera filter sized to fit your enlarger lens or a 3x3 dark red filter in the filter drawer of your enlarger. When I say dark red I mean a Wratten 29 or at least a 25. Will NOT work for color (or panchromatic BW papers) and I would run a fog test on all variable contrast papers.
I prefer to not use a filter and focus with a grain magnifier set on top of a piece of paper the same type as I am printing on and I stop down before focusing (I have one lens with a bit of focus shift as it is stopped down).

You may want to join one of the Rolleiflex mailing lists, one is at Freelists and the other at Yahoo. I think its possible a bit of Rubylith, available at art supply stores, may work to replace the original filter. However, I've never used the red filter on an enlarger. I use a scrap of paper the same thickness as the paper I am printing on under the grain focuser. This is probably not necessary due to the depth of focus is more than sufficient to compensate for the paper thickness. The brighter image will make focusing much easier. About the only time I use the red filter is for complex dodging or burning in.

A Wratten 29 should work, but a piece of Rubylith will be cheaper. They do still make Rubylith, I'd hope -- but I have to admit I can't see why...

These were once a single list but it split a couple of years ago. On is on Freelists which is a mailing list service. http://www.freelists.org from there you must register and can choose which lists to join. This one is called rollei_list. The other is on Yahoo and can be accessed there or via e-mail. http://groups.yahoo.com/group/rolleiusers/join You will have to register with yahoo. Yahoo wants to send mailing lists in HTML with advertising but you can opt out of this in your settings. You will have to reset them periodically. While both lists are officially for discussion of Franke & Heideke products they range all over the place. I am co-administrator of the Freelists one and can help if you have trouble subscribing. Write me directly for that. You will get a challenge message from my spam blocker but just return it and I will unblock you and answer the message. There are people on both lists who know the Rollei enlargers.
