    Get thee to a good old fashioned hardware store (NOT a big box home improvement emporium!) There is usually some old geezer wearing coveralls and named Gus or Lionel or Chester sitting on a stool somewhere in the back, with a coffee cup grafted to his hand, who has the answers which you seek, Little Grasshopper!

    Justin,

    I'm not sure what if anything the foam is designed for. It is fairly dense and comes in sheets that are 1/16" thick. Look in the area that has stuff like craft paper, felt squares, etc. At least that is where they are at Michaels. If all else fails, send me you mailing address and I'll send you some - I think I have some more left over.

    Use glazing points from the hardware store. The mount is solid enough for permanent use.

    The one on the right is "stock". The one on the left was bent with pliers for the recessed thread mount for this old flangeless lens. This mounting is solid and allows the lens to be screwed off if necessary.

    Hey, Justin:

    If memory serves, you've been looking for this flange for quite a while. I remember seeing your first post and feeling guilty that I had one sitting unused in my 'hoard'. Take a look at the pictures and see if your shutter looks like mine. PM me and make me an offer for this flange. I've got a lathe, and can easily make another.

    JBrunner: there are a variety of ways to cut threads. Your post brought a smile to my face, envisioning a tap big enough to thread a flange for an 18 inch Verito :o They probably exist, but it wouldn't be anything you could lift or afford.

    A bit of pedantry:

    With a lathe, the flange is mounted securely on a chuck and rotated. Through gearing, a groove-forming cutting tool moves through the flange at a synchonized rate, producing the desired pitch. The tool must make numerous passes through the flange, removing a small amount of material on each pass, to reach the proper depth of cut.

    A faster way of producing flanges is to use a milling machine and a hog. Picture a cutting tool something like your threading tap. With multiple cutting edges, it can cut multiple grooves simultaneously. Rotating at high speed, it's lowered into the middle of the flange, and the flange is moved sideways until the hog cuts into it to the required depth. The flange is then rotated, as the spinning hog is lowered through the flange. At the end of one rotation of the flange, the hog has been lowered one thread's worth, and each cutting edge lines up with the thread directly below the one it originally started on. The movements are usually under computer control to achieve the necessary synchronization. Hope that explanation is clear.
