Hi everyone,
I have a Vivitar VI enlarger but it does not have a lens board and bellows. So I made a lens board from some pieces of wood. I don't know whether it will work or not

I want to buy a focusing mechanism but it needs to be 12x12cm to fit the enlarger.

The only thing I found on ebay is this one: http://cgi.ebay.co.uk/ws/eBayISAPI.d...#ht_780wt_1185

Do you have any ideas how to make the enlarger useable? Thank you.
