Time to Update the Ground Glass Thread?

[Ari]

Bill Maxwell doesn't offer a combined focus screen / fresnel larger than 5x7. In his opinion, there's no way such a product could maintain sufficient dimensional accuracy, even with the stiffening clear glass cover sheet he considers an integral part of his 5x7 and smaller Hi-Lux combination screen systems.

For 8x10, Bill supplies only a plain fresnel, which must be combined with an actual ground glass screen. That's what I have in my 8x10, as well as a cut down version in my whole plate camera. In both cases, I've placed Bill's fresnel on my eye side of Satin Snow glass. Should one desire the fresnel on the other (camera lens) side of the glass, it's necessary to mill the back's ledge so focus ends up where film will be. Since I'm more than 6 diopters nearsighted, I don't need a loupe -- just peering over my spectacles provides sufficient "magnification" -- and don't worry about scratching the acrylic fresnel.

Thank you for the information, Sal; I'm kind of relieved that Mr Maxwell does not make what I want.
If you've ever used the Wista screen in the RF, VX or SP, I want that, but in 8x10.
I think Tachihara makes the same screen, possibly Cambo; not enough details online to know which is which and which will fit.

I just spoke to Jeff at Badger, and the Tachihara screens are no longer available.
Those of you who own one now have collectors' items.

Thank you for the information, Sal...

You're most welcome.

...If you've ever used the Wista screen in the...VX...

I have.

The Wista 810DX specifications

say it includes a "Bright Fresnel focusing screen with grid-line glass overlay." You probably ought to contact Bob Salomon and ask that he provide you the exact screen dimensions as well as a price for it (as a replacement part).

Didn't Bruce Wehman supply 8x10 plastic screens? He might have a lead if you drop him a note.

yes, he did. It seemed like it may have been a peel & stick film which was applied to the plexiglass. I could be wrong. I've seen some very suitable window frosting material at work which seemed fine enough for this purpose but never followed up on it.

Thank you, Sal, a very good suggestion; I'll do that.

Thank you both, I will follow up on that; I did find some contact information online, but no specific details pertaining to GGs.

FWIW, since I know Vinny (and some others among you) is a customer of Rudy's bellows services, Rudy contacted me this afternoon regarding their acrylic GG.
He says that the company that made them before is making them again, but have yet to deliver promised stock.
As soon as he has delivery of the GGs, he will list them in his eBay store.

I don't understand, why don't you just call B&H directly, and ask them to measure it for you?

They don't keep them in stock and it's a non-returnable item selling for almost $300.

That's a shame, wish they could measure it.
