My Toyo 45A has, what appears to be, a 1/2 inch tripod thread. I've never seen a 1/2 inch tripod thread before. I'm looking for an adapter to convert it to 3/8 inch but can't find one. Anyone ever seen such an item? It does have an adapter for 1/4 inch already in it.

Such things may exist , this is one I found searching eBay. Mover seen or used one and the thread may be wrong , ideally a Toyo manual or accessory list would tell you the thread pitch

Thanks for that. But the 1/2 inch side has the wrong pitch. That is 13 tpi and the camera has 20 tpi.Such things may exist , this is one I found searching eBay. Mover seen or used one and the thread may be wrong , ideally a Toyo manual or accessory list would tell you the thread pitch

From the Toyo manual, the cameras were originally supplied with both 3/8 and 1/4 adapters. The 1/4 is fine to use, it's not a heavy camera, but I would have prefered to use a 3/8 if I could.

If you can't find one I can vouch for this place being able to make you a custom one. Prices are pretty reasonable.

The manual I have says both were supplied with the camera but, inevitably, the 3/8 one would have been rarely used and then lost.
That's the one.
I'll probably drill and rethread the one I have. I can then add a standard 3/8 to 1/4 adapter if needed later.

Would Toyo provide a 1/4" connection if it wasn't strong enough?
Probably not, but strength isn't necessarily the issue. Depends what you want to mount it on. I have a head with a 3/8 screw I would like to use.

My 10x8 Agfa Ansco cameras all have 1/4" tripod threads, as does my 12"x10" field camera, there are no issues with stability.
3/8" (or a metric equivalent) was used by many pre-W2 German camera manufacturers, but it was also used for heavy LF and professional 35mm cinematography cameras, also broadcast cameras.
Like you, I have a really nice big tripod that is a fixed 3/8" screw thread. It's actually an Australian made tripod for old TV broadcast cameras. It has a sort of large ball head that the centre column sits in. The stability of a heavy tripod but allowing you to pan or tilt while filming. I've had the tripod for 20 years, but no current LF camera that can use the 3/8" tripos screw.
The remedy in my case is make a new tripod block for my 10x8 Agfa Ansco and add a 3/8" tripod socket, I'm planning to make one anyway for one of my other 10x8 Agfa Ansco cameras, before I sell it.
