hey all. i've got a recessed board for my toyo view C. it's currently drilled for a copal 0, but the metal is also scored around the opening for a copal 1 size. i need the larger size so i can try all sort of wacky experiments with process and enlarger lenses. any idea how i can punch this ring of metal out so i can use the larger size hole? using Ordinary-Guy tools, not I-Hide-a-Machine-Shop-In-My-Garage-Guy tools.
I don't think that little groove is actually intended for punching out with ordinary-guy tools. You might try a half-round metal file, mixed with a large dose of patience. Otherwise, it's machine shop or at least a hole saw in a drill press with a centering/hold-down jig, I'm afraid.
One other alternative is a metal hole punch used for making holes in metal electronics chassis. They aren't particularly cheap in these sizes, but the only tool required is a regular-guy wrench.
I don't think it's scored really. That's so the shutter fits right. If that area hadn't been reliefed I bet the board would be too thick.
You need recessed board for process lenses? Considering the cost of a recessed board wouldn't it make more sense to hack a flat board?
Ralph: Rats. I was hoping you'd tell me a stout screw driver and a mallet would be enough to knock it loose.
Nick: it's definitely a groove, so it should have no bearing on whether the shutter seats properly or not.
The process lenses I have in mind are all short focal lengths, and would likely get used with a roll film back (or, with vignetting, on 4x5). I do need the recessed board, otherwise I would run into bellows restrictions. Lenses are anywhere from 50mm to 127mm. Some need it, some don't. But the recessed board was extremely cheap.
So looks like I'll have to take it somewhere? Rats.
Hi, Rippo.
You might check out used boards at KEH.com or on ebay. A trip to a machine shop can be very expensive (but that's you only good alternative). You might find a good used one at a much cheaper price.

thanks Tim. every recessed board i've come across on ebay has been sized for copal 0. i see others that have this same scored ring around the opening as well, but haven't yet seen any for copal 1. i can keep looking i guess, but it seems a shame not to use the one i have. but yes i don't want to spend tons of money on it.
The holesaw followed by a half-round file works. Or you can drill out a start hole - then use a jigsaw. Or just drill all around the circle with a small bit - then knock it out...finishing off with the file and or sandpaper. I have just drilled out one of mine ( holesaw wasn't big enough ) then epoxied on a front panel from a dead technika . So now I've got a recessed Technica adapter board.....which Toyo don't make...and i can focus a 65 and 58 XL schneider ( great lens ) no problem. So I'm having a resurgence of faith in my 45 G's. more customising planned. There used to be an add for Toyo tyres in Australia - but obviously thought of in Japan - " if you want Toyo performance, you must fit Toyo ! " Am now applying that motto to my photos. Will see what happens.
Keep experimenting Rippo - and others - surprising what can develop ( pardon the bad pun ).

Why not just go to Samy's and have them do it properly for you?
I have had good results with a Dremel on both aluminum and wood lensboards. After you enlarge the lens hole, then you can keep the Dremel for future projects
A bit like this grinds off aluminum pretty easily.
