This machine shop is one of the best in the multi-state region with experienced people and state of art machinery. They've made a couple of flanges and lens parts for me in the past. It wasn't someone working out of a garage. Will take it back for them to look at yet this week.

GOOD! IMO, this is the proper way to get this done. While at the machine shop, ask then to fit this flange to the lens board. Machine tools can do a remarkable job on wood or metal. If possible, remove the lens cells from the barrel before it's trip to the machine shop to limit damage to the lens cells.
As for home garage machine shops, it varies lots. Some are hobbyist tinker types trying to learn how to used their midget sized machine tools. Others, quite serious in every way. Years ago this story in Silly valley was told about a highly skilled and specialized artist who made quartz spheres for space flight gyros in his garage. These quartz spheres must be spherical to the extreme as the performance of these space flight gyros depend on it. Turns out, no "company" was able to produce these quartz spheres are good as this guy in the garage machine shop..

Finally got some time today to take the flange in. One of the machinists played with it for about 20 minutes and when he was done it works great! He said they did have it cut to too fine a tolerance. There was some variation in the threads on the barrel. It' goes on and off easily now.

Great news!
I once bought a giant lens from a faraway country, seller said no flange
I asked how much to make one
Glad I did

Once found and acquired a large Petzval barrel lens in an antiques shop for little money (so wish that I had kept it) in the 1990s. Went to a local machinist shop to have a flange made for the lens. Quoted price was several hundred dollars. Next went to my local High School's machine shop, and was quoted a price of only $20.00. In the end paid the school's machine shop $100.00.
