Prospective customer just came in asking if I can do Dime size circles up thru Dollar size circles in "thick" matboard.

He proceeded to tell me he has checked "all over the country" and no one can do this for him.

But, being the connected person I am (yeah, right) I thought my fellow grumblers will know the answer and possibly solution to this!!

He wants a mat cut with a total of four sets across of all the coin sizes...

what'cha think?

Thanks

Roz

PS He's willing to pay for this custom project if it is "reasonable".
 
No problem. Here's a sample cut in a scrap of A4901. Dial caliper provides actual scale (0.7" diameter)

Nice job, nice pics Andrew!

The smallest I've done is when I use my Wizard to cut tiny circles out to use in the opening in the middle of CDs to hold them down to a backing board. I use the dropouts but the circle opening left in the board is perfect.
 
Andrew - nice cut!! Do you use any adhesive to hold it in place?

Thanks,

Roz
 
The customer also said "thick" mat board - to be the depth of a half-dollar or the dollar - I am thinking 6 ply?! Since I don't have a coin here to compare it to..

Roz
 
Does he want the board to hold the coins? Maybe he's expecting a non-beveled cut so they fit in there snug.
 
I think he is expecting a non-beveled cut - but if we do a reverse bevel - that could work!??!
 
I don't think so, unless there can be a separate backing board and the coins sit on them until the mat comes down to hold them all snug, which is probably a pain. I'd use my trusty C&H Oval Master with a straight cut blade if there weren't many to do and assuming I could get the sizing perfect enough. I tend to think I can do anything, gets me in trouble. If it was going to be a large production I'd offer to sell him my C&H Oval Master.

You can do a dime sized hole with a C&H??

Wow, I couldn't get down past a little over 2" with my Fletcher 1000.

I may buy a C&H if they go down that small and cut an even hole to boot!!

Roz - I have a Keeton circle Kutter which goes from 3/8ths to 8" - straight sided cuts - I'll lend it to ya if ya wants. It it vewwy vewwy precious to me but I trust you!!!

I even have extra XActo blade - #16's! Great little piece of equipment - perfect for coins!

Let me know!
 
I told ya I think I can do anything! Yeah, I haven't had to use that bugger in so long that I forgot about the size limits. When I go in Monday I think I'm going to bring my Wizard flowers and a bottle of Courvoisier just to remind it how much I love it. Maybe I'll even get some.
 
Mar- I've got one of those too. What an ingenious little tool. Saved my @ss on many projects over the years. RIP Keeton.

Rick - isn't it just the BEST??? I was helping Keeton at a NYC show one year and my job was to walk the aisles of the show just cutting circles "in the air" with the thing. Knocked people's socks off.

I bet there are a lot of 'em out there sitting in drawers or boxes and people have no clue as to what they do. I use mine A LOT!!!
 
Now let me get this straight. He has checked 'all over the country' and found this to be a most difficult task. He has hope, but it is fading. YET he says he'll have the work done if it is 'reasonable'. Now does he wish you to accomplish the Darn Near Impossible or does he wish you to do a Cheap Job That's Hard? Can't have both...
 
I have done this several times. A reverse bevel works fine. I don't recall matting a dime. I don't think radius would be a problem. The problem will be the thickness of the mat.

For example a quarter is almost exactly the same thickness as a 4-ply board. The reverse bevel holds the coin great! But if the coin is thinner than the board (like a dime) what is going to hold the coin? I think this would be a problem with dimes and pennies mostly.

You might get a regular bevel to work like the picture and let the glass hold it in place but I would think the coin would slide out of the bevel. I have the same fear of a reverse bevel and thin coins. At least with a reverse bevel you can use lots of glue to hold the coin in the hole.

Hogwarts has a spell for this but I can't remember it. Let me go grab my book of magic.
 
The newer CMC designs have better capabilities than the older ones, like mine. For example, the Fletcher/Valiani MatPro 150, their entry-level machine for under $13,000, will cut perfect circles about 1/4" diameter. They look like small, conical craters in the mat, because the bevel takes up most of the area.

That machine will cut 8-ply, too. But I imagine the circle would have to be somewhat bigger than 1/4" diameter.

Instead of trying to cut coin-sized circles in 8-ply board, especially if the bevel is undesirable, I suggest placing two 4-ply mats back-to-back with their bevels reversed. And if more depth is needed to acommodate thre coin's thickness, just add paper spacers between the mats.
 
Roz,

Let me know if you need help with this, we could test it when Greg is in town and he can take back some samples to you. Just define the requirements that you want, and we'll have a go at it for you.

Oh - You are all the best!!!

Mar, Thanks for your trust - I appreciate it and my just take you up on it.. and maybe I'll just send him over to you!!! Hey - it's only an hour drive!!

Ellen - typical eh!??! wants the impossible for not too much... we'll see what his idea of "reasonable" is...

Elaine, I'm not sure what he wants but will let you know when he calls back with more details.

Thanks to everyone for your responses!!
