    The mat board is strong enough?

    I'm not sure of the one pictured, but on one of my heads those three fasteners are hex-heads that can be firmly snugged against a head that has recesses. They are accessible from the underside.

    Or if all else looks unclear, making a thicker wood or metal disc that fits between head and mtg plate, that might be drilled a little off-center so that the head is secured to the disc with a bolt, and the disc attaches to the mounting plate bolt with a tapped hole (for a metal disc or square, triangle, etc), or for wood, a T-nut in the wood that will hold the center bolt... That would do, and be very strong...

    As long as the difference between the 2 diameters is small (just a few mm) it's good enough. It wears, but then I simply cut a new one.
    Should the difference in diameter be larger then a metal disk would obviously be better, just like LabRat explained.

    I took the precaution of emailing Berlebach to ask their advice and they have pointed me to this:

    The recess is too deep and/or the fasteners are too short; they fall out before they engage with the head. And it's more cumbersome than the mat board.

    It turns out the Sinar pan tilt head also has a 1/4 screw. I've ordered a few bushings for now.

    It's funny as the only time I have ever come across equipment using 1/4 was an old Kiev MF camera I had. I did not think there was that much use for 1/4 everything else of mine has been 3/8.

    Really? Mine has 3/8 threads. I threw away the 1/4/20 adaptor that the guy I bought it from had put in it. L

    Clearly you have not come about some Deardorff nor Linhof LF cameras, but you might eventually.

    My Linhof Master Technika 3000 uses 3/8-16 threads. Of course that's a sample size of one.
