Homebrew PCBs

Hi Everyone,

I'm a current reader of your posting and devoted to photographic process as I'be been working for years with graphic film isolating with UV and vacuum.



Please would you suggest how-to cut PCB (phenolic or FR4) in circles of 19mm ?

What first came to my mind, wah doing it with a small vise with circular movement working as a compass.

Do you think that there is any better method ?

Hope your hints.

Best,

Rafael

Hi Everyone,

I'm a current reader of your posting and devoted to photographic process as 
I'be been working for years with graphic film isolating with UV and vacuum.



Please would you suggest how-to cut PCB (phenolic or FR4) in circles of 19mm 
?

What first came to my mind, wah doing it with a small vise with circular 
movement working as a compass.

If you don't mind a hole in the middle, a tank cutter should work.
