Advise for Durst L1000 Otoneg2

[photonsoup]

I have the Otoneg2, But I don't have any masks for 4x5. I have 3 weird sized mask sets that I can have a machinist cut out to 4x5. I found some new Otoglas inserts online, one plain one anti-newton.
Do they just mount in the Otoneg like the masks?
Is the glass better than the masks?
It seems like it would be a difficult to keep them clean, but I assume they hold the negative flatter.
Can you then stick any size (smaller than 4x5) negative between the glass?

Yes the glass inserts fit in the same way as the metal masks. And yes you can place any size negative (smaller than 4x5) in them if you want; they will just be unmasked as it were. Glass inserts will keep the negative absolutely flat.

Cheers, Bruce

You can also get an Omega D series negative carrier and have a machinist cut and grind to match the negative plates.
This is what I will be doing myself, as I have not been able to find the negative plates at a reasonable price.
