lens boards for 138s durst

I use step-down rings for any lens instead of the Lapla regular ring. As I have 5-6 lenses with different threads this is the easiest way to go (Rodagon 210, 105, EL Nikkor 210, 180, 150). the 77mm ring fit perfectly inside the 138 tripla turret and obviously also on my second enlarger M700, used for 35mm printing.

Great idea!

That's what I did for my 210 Rodagon.
