    If only you made them 1cm bigger...
    George,

    I had the same problem for my Omega DII but I bought the Ilford 15cm filter set.

    I made a cardboard holder for the filters that I put into the filter slot so they can't fall down. It also protects your filters from being scratched.
    Just wach for vignetting.

    The 0 and V are permanently fitted in a cardboard holder for splitgrade printing, the others go in a sleeve so I can change them quick.

    Go to the glass shop and buy some plain glass the right size. Put an edge around it. Duct tape? The put that in the filter slot. Place the filter on the glass sheet. You don't want to know how big the filter drawer is on my Beseler :rolleyes:

    Which Beseler do you own, Nick ?

    I thought about finding a way to make the smaller gelatins hold in the drawer, but it will still leave a part of the opening exposed to unfltered light. Or, as my Flemish friend suggested, I can make a frame that is smaller than the drawer and fit the filters in, if it won't result in vignetting the light coming from the lamp.

    Paul you're right, the 45MX filter drawer is between the condensors. Do, if the filter falls from the drawer it will not go too far, but this is no reason to let it fall...

    Finally, I will have to order the Ilford set from somewhere on the internet, because the Greek importer will never bother bringing it for me...

    I've got a CB-7 that takes 7"x7" filters. I think Beseler at one point sold a filter holder that held the filters in place. Odds are they did the same thing for your enlarger. At least I doubt it needs anything bigger then 6"x6" filters. Even if you're printing a 4x5 negative a 6x6 filter is at least 1" bigger.
