    bellows material

    Has anyone used BK 5 for bellows? If so, how does it work?

    I am looking for something just like this for a MF folding camera restoration. The thickness seems right. I was advised to use 0.007 leather, if building from leather if the camera is to be able to close on the new bellows.

    Regretably, the quantity on offer is a bit too large for me to bite on buying this on spec. I need a a piece about 30cmx60cm maximum.
    my real name, imagine that.

    Hi Chris,

    I've made a set of replacement bellows for a Century studio camera using two layers of BK5, and it came out quite nicely. One layer of BK5 is not completely light tight. However, with two layers of BK5 bonded together with contact cement and railroad board for the ribs, the final sandwich is very thin, flexible and light tight.

    Best,
    Daniel

    Thanks Daniel, just what I needed to know.
    Did you use spray contact cement like 3M 87?

    I'm building a 6 1/2 x 8 1/2 "traveler". For my biking around the city. Not sure when I'll get around to the film holders but the camera should be done in a couple more weeks.

    Hey Chris, I believe there was a thread a while back discussing the various merits/weaknesses of adhesives for BK5, but I've found the spray contact cement like 3M 87 was adequate for my purposes.

    Hope all is going well for you.

    Best,
    Daniel

    Have you tried talking to the friendly folks at Custom Bellows?

    http://www.custombellows.co.uk/

    They may sell you some of the 'real' bellows materials and some plans on how to do your own. It's worth a try.

    Ralph,

    Thanks for the suggestion. I had them make a bellows for me and I was very happy with the results. I'll contact them.

    My search for bellows making material ended over the week-end. In my favourite camera store i found 2- 14"x33" rubberized cloth blackout window coverings. They appear to be perfect material donors for the bellows fix project.
    my real name, imagine that.
