Just thinking. Why not cast a slab of resin-set sand, CAD-Cam rout the letters into that, and use it as a mold to cast the plaque? Has anyone tried something...

... Here is an Instructables showing how to build a CNC mill for less than $200. I don't see any reason why it could not be scaled up to the size required for...
A suggestion. Why don't you just figure out how many letter "A"s you need, how many letter "B"s, and so forth, and make sand castings of them using CONCRETE as...
... That sounds excruciating! Especially when a machine could do it in an hour or two. In todays day and age, seems like only someone with something to prove ...
I hope to have at least 8 or 10 plaques done by August 14th of this year. We are having a 100th anniversary for a dam by our town. OK, its a small town and...
That would be a good idea for the larger letters, but even with plaster sand the sand would be to large for most letters, as they will be between 3/16 and 1/2...
Unlike metal, concrete doesn't shrink when it is molded. So you can make numerous copies, of your copies. So you take ten letters, mold them ten times, and you...
... To me, typesetting 40,000-50,000 characters by hand is the equivalent of moving 50 yards of sand with a spoon. Now, if you were tasked to move 50 yards of...
Hi Folks, How about doing it the way sculptors do? Make a clay positive with all but your letters. Get Plastic letters- Press them into the clay - along side...
We are all "brainstorming" here - trying to come up with ideas. Some ideas may be better than others; some not. What works, works. What does not work, can...

I think the method of casting is going to affect what process he's going to use to make his letters. I dunno...that's a lot of letters. Maybe go to an old...
If you can get access to the right equipment, the easiest way to do this would be a photopolymer plate. This process is used for printing. I have not seen it...
Check with a sign making company. the one I used acid etched an alloy plate to the desired depth of the letters including draft. the 1/16" plate was glued to a...
What you want is a flexographic plate. This is a photopolymer material it comes in MANY thicknesses, and your design is simply exposed onto the plate,...
You can build your own light set up for doing this and you can scrub the plate with cold water and dish soap. The depth of relief depends on the exposure time....
Just to nail down one loose end...the "flexographic" process is one and the same as the "photopolymer plate" process I was describing. Also, you will have to ...
If copper is good enough for your plaque, you might also want to look into the process used to photo-etch or toner-transfer etch printed circuit boards. To...
Perhaps I missed something- but the easiest way for me to figure doing a few plaques like you need may be as simple as hiring one of the many folks here in our...
Again I want to thank everyone for their suggestions, some were real good and some would have taken months to make a plaque. What I finally did was go to...
