Negative masks for Durst Grahalon and how to use it

[Drew Wiley]

What you show in the correct picture is not the full carrier, but just the registration insert tray. Do you have what that slides into?

[foen]

Yes Drew, I've the second part of the carrier hold down in my enlarger right?

Check with Focal Point for the glass. He's going to be cheaper than anyone else and probably already has the dimensions. Anti Newton glass (or plain) on top, plain glass on the bottom. L

Ok Luis tank you. So I send a email to focal point.
So how about the best practices to keep clean and dust free the glass?

[Drew Wiley]

Carrier glass will be a bit thin and fragile, so you need to handle and clean it carefully. What I do is to remove the glass and use a bit of glass cleaner or dish soap and a soft nylon pad similar to what you clean teflon pans with. Then I fully rinse this off under running water, then blow all the water off using a compressed air line. Then I let each piece air dry a big more before actually placing any negative in there. This is done under an inspection light, so I can see any bits of dust on anything, beside an electronic air cleaner, pulling the air away from the work piece. A low-pressure, fully-filtered air line is beside this, with a blowgun for removing any bits of whatever. The room itself needs be frequently sponged down to keep all work surfaces clean; and for fussy projects I wear a true clean room smock, which resembles a lab coat but is made of 100% dacron long fiber, so produces zero lint. Some darkroom workers laugh at this degree of fuss; but when they have such a hard time controlling dust, it's my turn to laugh back!

On the focal point website.

Thanks foen to posted your carrier, if we look carefully the other one, it was in fact a Grane 205, the 8x10 version!
I saw that yours have four screws, can someone who had this carrier tell us if theses screws help to retain the glasses or if it is only the moving corner at top who secures the glasses.
Also if you have this carrier, let us know the exact glasses sizes and if it is 2 or 3mm.
I don't see thoses glasses on the Focal Point website, only the Nega 138 glasses are listed. Probably need to be custom cut.

Hi all, so the exact sizes are 14.5 mm x 18.1 mm x 2mm of thickness. I'm waiting for.

Thank you all for the right advices about glasses, my only fear is the dust.
