I couldn't find the exact answer to my question from searching the forums.... I recently acquired a Speed Graphics 4x5 with the intent to use barrel lenses and other large lenses.
However I over looked the fact about lens boards. I know it's possible to use Aero Ektars, large petzvals, or any other large lens on the speed graphic. I've seen the JoLo stuff (plus he doesn't sell JoLo44 anymore) , but I know people for decades didn't use his equipment.

Any links to step by step instructions (with images)?
Or does anyone 3D print them?
Or selling a JoLo44 plate?

Again, I have a Speed Graphic, not a Pacemaker.
I'd like to use an Ektar or 8" Pentac soon.

Thanks,
A.
