    Schneider Componon 5.6/150 Thread Size HELP!

    Hello, I am having trouble trying to get the size of the thread, I have checked the website I measure about 40mm just with a ruler. its a 70's lens, so I wondered if anyone can help or knows the size the serial number is 12 426 266.

    I will also need a mount so I can put in on my enlarger, where can I get one of these from in the UK? its for a Durst Laborator 1000.

    What's the lens board like, if it's similar to the M601/670 etc I think I have one but I'm not back in the UK for 3 weeks.

    OK, I wasn't or rather hadn't been thinking of selling it but I have no use for it, it came with a job lot I bought for an M670 and analyser etc.

    Look first and if you haven't got hold of one before I get back I'll double check it is M42. I know I have one board slightly larger than all my other Durst lens boards, all my smaller Componon's etc are M39 (some with adaptors) and the rest are far larger I have a 300mm Componon & that weighs about 5 kilos

    Went through a similar problem with my Rodenstock, but was fortunate that it was an M39 thread and was already set up to cut that pitch on my lathe - Len boards (can be) expensive on fleabay, and the M42 versions are like rocking horse.... Short term, you could always glue a few disks of mountboard together.

    and also stop talking to my self :S
    Perhaps getting out more might help

    M42 x 0.75 retaining rings and mounting flanges are available but might cost more than you'd expect.

    A coating of carpenters grade slow set hot glue laid out as a bead onto wax paper and then picked up and wrapped (by rubber glove protected fingers) onto a lightly vaseline smeared thread on the lens is a way that I have improvised lens retainer rings.

    Lens boards have been improvised with 3 layers of black matt board glued together with scotch 777 rubber spray adhesive. Cut the hole for the lens first. Cutting three layer of matt board at once is not easy; I have tried that only on the first one made this way.
    my real name, imagine that.

    Lapla 42 lens plates show up on ebay. I got one a while back for less than $50.
