Hey all,
I was in search of a lensboard extension and came across
https://rafcamera.com/ They make many adapters and tubes etc.
I had a spare Copal #3 lensboard and the hole is standard 65mm,
Knowing this gave me the idea to build my own top hat extension using parts from RafCamera
Here is what I ordered from them.
60mm extender for M65x1 thread
https://rafcamera.com/extender-m65x1-60mm
M65x1 female to M65x1 male thread adapter (30mm long extender)
https://rafcamera.com/adapter-m65x1f-to-m65x1m-30mm
41.6mm to M65x1 thread adapter for shutters, wide
https://rafcamera.com/adapter-41-6mm-to-m65x1-85mm
Lens board (lens flange) for M65x1 focusing helicoid, round
https://rafcamera.com/plate-m65x1-round-d82
Cost me $134, and a couple weeks shipping.
All the components fit together well. And are well made.
I have used this for my Fuji 400T on a Toyo 45AX to get that extra bellows depth.
Here are some pictures.
