PB-4 Bellows

[charlie]

My PB-4 Bellows has some holes in it and I was curious if anyone here has had to replace theirs and might know where to source a replacement?

A piece of black Permacel or acetate tape might work.

I'm not opposed to repairs as needed but was curious if replacements are out there seeings how it will only get worse over time.

Thank you.

If money is no object, I'd try this company first:  http://nabell.com/optical-bellows.html

Looking at my PB-4, I think the biggest challenge would be to remove the old bellows and adhesive before attaching a new one.  Horizontally, there's lots of room, but vertically it's a tight fit.

i would look for another on eBay.

Black liquid latex?

I thought about that for my own tatty PB-4 but have not tried it as I found an almost like new for next to nothing.

3 options:
1. Gaffers tape, I've tried it, works.
2. Black latex thingy. Repaint the bellows. Works.
3. Get something better than the fragile imprecise PB-4. A PB6 is a great start.

As a fairly impoverished Photography student (subsisting on a much-too-tight Allowance!), I once made my own bellows for an ancient mahogany technical camera.

They were made from brown paper with cardboard stiffeners for each pleat. Black fabric formed the lining and I painted the exterior with several coatings of black latex paint. Those bellows were entirely light-tight and functioned perfectly.

I can highly recommend black latex paint for bellows renovation.
