    FOTAR also used the Vapla round beveled edge lens board design, but a different OD size. Not interchangeable without mods.

    I was about to make a few from high grade plywood, but found 4 on eBay and bargained the seller down.

    If you have a Vapla with a big enough hole there are many ways to just drop a lens in the hole with almost any other lens board and gaff tape the lot.

    It is metric, about 200mm. Just shy of 8", so I was able to find some nominal 8" items at Home Depot that actually fit. Home depot had these "50mm lens adapters" on sale for a few bucks. I used it until I found the proper Durst item. As I recall the hole for the lens was even the correct size to hold it in with a retaining ring ... go figure.

    Oh gosh, a plastic ring from a big box store on the snout of the Grand Champion prize bull of the County Fair? Oh well. They all end up as hamburger eventually. If you make an actual replica in the shop, note that there is not simply a bevel around the circumference, set at a particular angle, but that this bevel does not comprise the full thickness of the plate. A tiny bit of that thickness is at a right angle, if you're after an exact fit with the tightening mechanism on the enlarger itself. Mine is bolted in at the moment with a lens in place, or I'd measure it; but I wouldn't personally gamble with nominal measurements.

    Actually steel. It is a lamp bezel. 8 inches is a standard size for many lamp fixtures.

    For example they also sell this. It is steel and 8" with a tapered edge. $15.

    No honorable bull would be caught wearing that either. Fortunately, all the bulls I walked right past today were young black angus bulls a lot more interested in chasing cows than another stupid photographer like me.
