Hi,
I am completely unschooled in metalworking.
I have a metal 8x10 on its way to me soon, and I'll need to make a few lens boards, maybe even a Technika adapter.
There are some cheap drill presses available locally, but I don't really know what they do other than punch holes in stuff.
What's your advice?
Thanks in advance.
EDIT: Whoops, posted in the wrong section...again.
Sorry, mods; please move to the lounge.
Thanks
Make a wooden lensboard and don't bother with metal.

Ari,
If you want a quality product in the long run, just contract SKGrimes to make an adapter for you.
Or get them to drill boards for you, they charged me $30/each, this also includes affixing flanges if you supply them(if you have lenses w/ flanges that is).
What camera are you (making) boards for?
Ari,
Some boards, Linhof for example, have light traps built into the back of the board. Will your camera need a trap? If so making a board just got more difficult.
The first step to making your own board would be to get a manufacturer's board so you can see and measure exactly what has to be done. Then you mill (not drill) the hole for the shutter.
Hi Daniel,
Thanks for the advice.
I have an Eastman Commercial View coming this way.
If it's a matter of having someone else make holes, then I can find a local shop.
Bob,
I made some wooden boards with a light trap, and they worked very well.
A Technika adapter might be a different story, harder to make.
There will be an original board included with the camera, so I can use that as a starting point.
Thank you for your advice.
Depends on how thick, assuming aluminum. I'd just go to ebay. Otherwise hole saws will do the job just fine on a decent drill press. Light does not bend around corners as far as i know. I've made boards from abs, plastic, wood and never had an issue with light leaks but maybe w/your camera i suppose light may bend. Aluminum can be cut on a table saw w/ the proper blade. I've made two linhof adapters from 1/4" ABS, it's easy to rout/cut.
Thanks, Vinny; yes it would be aluminum.
EBay would be better and easier, but I haven't seen a reasonably-priced metal board there for some time.
What I have done with the Plaubels I have bought (which have very costly and complicated lensboards) is to buy a Technika adapter from here which is the only one I could find with an additional inner flange. I then cut a square hole in the Plaubel lensboard a little bigger than the size of the inner flange of the adapter using a coping saw, I then mounted the adapter onto the Plaubel lensboard, stuck it down with gaffer tape whilst I drilled a small hole in each corner for a rivet. Before riveting I stuck some thin closed cell foam around the opening on the Plaubel board so that when the board was riveted there would be both a good light seal and some form of cushioning to prevent any movement.
Actually seemed to take longer to explain than to do.
Should be just as easy with any other type of adapter as I have seen varients to Sinar/Horseman boards too.
Ari, You have to be really careful drilling metal. The bit will have a tendency to grab the metal with unforeseen results, and whatever you do, don't use one of those adjustable (wing cutter) drill bits, you will lose a finger, or worse in a split second. The coping saw would be a better way to go, or a table jig-saw, that's what I've used with success.
Also, it seems if you're making a lensboard for 8 by 10, the lens is going to be big, thus you'll need thicker aluminum, and the light trap design Bob mentioned is important.
Good Luck,
-Brad
