Where to Have lens board hole mistake fixed?

[seabee1999]

You could have a shop drill a hole in the right place.

Assuming this is a cast lensboard not a stamped speed graphic styles one, you could then fill in the missing metal with either a tig welder or jb weld and spray paint that area again.

I was going to suggest this as well. Perhaps even welding a piece of aluminum sheet metal to the back, filling the hole with new metal, grinding down the excess and drilling a new hole; all of this provided that the metal of the lens board will accept the new metal being placed.

I wouldn't weld or even solder. That could warp the board. Not to mention that's more complicated than other options.

I would cut out all but a "lip" out of the back of the lens board. Then take a cheapo lens board with the correct hole> pop rivet and glue it on (black silicone) with hole in proper place>trim to fit edges that are sticking out.

Bore the back of the recess out, and have a "flanged plug" made, that attaches from the back to re-establish the correct depth of the recess. Local machine shop.

ok guys, here is said Toyo 25mm deep recessed field board after hack job, don't laugh too hard. But they actually charged me for this "work".

That's not that bad but if it bothers you (it probably would me) then...

Just have a precise #1 hole cut and buy one of THESE

You'll also need a #1 retaining ring which costs about US$7 delivered.

Or you could just use it as-is and replace it when another recessed board shows up. After using it awhile you may decide it's just fine the way it is... save some money. If you're not shooting precise architecture I doubt you'll even notice it. Knowing myself... I'm pretty sure that's what I'd end up doing.

Not so bad!
Maybe the easier solution is to ask to a machine shop to cut a clean and centered Copal 1 hole and to use a Copal 1 to Copal 0 adapter. This way, you will also have the choice of Copal 1 and Copal 0 on that recessed board.

Some people do not care about a lens curvilinear distortion characteristics. Others notice chromatic aberration. To each his own.


But thanks to everyone for suggestions. I have enough info to get a solution that will work for me. Thanks again.
