Looking for someone like SKGrimes in Europe to machine a speed graphic lens board and make flange to mount a petzval c. 52mm .
Anyone know anyone please?

I would visit several machine shops in your area bring your lens along. Talk to the machinist on duty. If they are slow they may set up on the spot & have it finished by the end of the day.
The only trouble I have ran into is when the flange is over 100mm. Then the lathe clamps can be to small to hold the brass/aluminum . They usually have to make a rig to hold the material in the lathe. Then the price goes WAY up.

I think I paid somewhere in the neighborhood of $400-$500 for a 200mm ish flange to fit my 21" J&D Petzval Cone lens . Man that hurt a bit.

The size your looking for should not be a problem.

52mm sounds very familiar. This is the most common flange size on smaller magic lantern petzvals. 4 of mine have this size. You may find it cheaper to search the bay for damaged magic lantern lenses with flanges or check the frequent lister of lost flanges there.

I've had decent luck with flanges under about 65mm. Anything bigger gets dicey and less common. TTH and Wollensak flanges are usually easy to identify with detailed photos. TTH are always marked if original, and are a bit more "standard" in sizes.

Where is Jorge from, William? or where is he located?

What do you guys find the average flange (<65mm) goes for? (if made of course.)
