As I said, there won't be any problems in the future. Even a loose thread will be tight enough when screwed home. The whole system is really over engineered. Even two bayonnet fixture type flange will hold a heavy lens firmly.

Just a note that you can securely mount most large lenses without a flange easily and cheaply. Here's my 13 inch Vitax and a smaller lens mounted with bits of a rubber sewer connector and a ring clamp, $7 at Home Depot. (Yes, I'd rather have the original flange, but we have what we have...)

That's a good idea, Mark. But in this case, I'm the crazy fool who is mounting a 13" Vitax on this 7x11 Eastman View No. 2, so I'll need it to easily screw in and out of the flange because I'll have to do just that every time I set it up and break it down. In an earlier thread I was asking everyone about a lens support. You can see my homemade solution in the picture. The camera has the sliding tripod mount so I'll be able to adjust the placement based on the center of gravity. I'm having a fellow in Chicago fabricate a mahogany lens board with the giant hole cut for the Vitax. I sent the original wide lens board to him so he could match the dimensions and stain. The original has been modified to accept 6x6 square boards and I have two of those that go with the two lenses that came with this camera, a Turner Reich Triple Convertible (12-21-28) and a Wollensak IIIa 159 mm/12.5. So I'm waiting on that lens board, now this flange (I found a willing machinist this morning), and Ilford to do its ULF film run in April so I can buy some boxes of 7x11. I also have the 8x10 and 5x7 backs, so I can really get started using it once the original lens board returns from Chicago, which should be as early as next week.

Thank you fellows once again for all of your insights.

I'd say that's a damn-fine idea right there!

A little complected, but such way is good for onto Sinar Auto shutter.
