Ehh a radius can only be found in a circle?

If you are looking for a corner rounder, I think what you are looking for is 1/8" (3 mm).

I just checked "The Gaff Factory", and Magiguy is correct.

Positive it is 1/8th?

I have heard 1/4 1/8th and 3/8ths so far.

Is there a definitive source for this information?

3/8 is HUGE!

I've read 3mm somewhere but don't recall the source! I've become pretty proficient with nail clippers!

I use a 3mm reverse angle nip, and the cards line up perfectly with poker size bikes.

I did a couple of quick measurements and a quick calculation and came up with 2.83 mm. I'd say that the 3 mm (1/8") guys have it.

I have always used a 1/8" corner gouge to round the corners of my cards and they match the standard playing cards.

1/8th" has in fact proven to be the exact cutting radius and as such an appropriate cutter is on it's way few UPS as we speak.

Thank you for the rounder recommendations!

I decided upon a heavy duty cutter.

This is probably going to ruin your day but Chris at Lybrary.com sells a corner rounder for under $30.

Some folks put quality ahead of price.

http://www.holepunch.com/cornerrounding.htm

No. 45-CR is handmade in America, and does a perfect corner. This tool is cast and machined.....not punched out of Chinese pot-metal.

I've got both the one linked to above, and the M.C. Mieth........there's no comparison.

One day in the shop I needed to just round a few cards so I took some 1/4" I.D. brass tubing (1/8" radius), ground it to shape, sharpened the outside edge and it works fine as a corner punch.

You use it on a soft board and hit it with a hammer if you can picture this, sort of like a leather punch. But this is just for an occasional radius since it's slow going.

There's a cheap dual radius one available on Amazon too with quarter radius and eighth radius on the same punch. Did I say cheap as in cheaply made in China. I think if I needed to buy another one I'd go for one of the better ones pictured in this thread if I had a bunch of cards to cut.

I have tried and purchased a number of rounders. The one I sell for $29.50 works perfectly and makes the exact corner rounding you find on USPCC poker sized cards. http://www.lybrary.com/corner-rounder-p-33513.html

Yes, it is made in China. If that is a problem for you then look for something else. But in terms of quality it is as good or better as any other rounder I have tested. Actually it is more heavy duty than others made in Europe or America. You can cut with it one to five cards at one time.

For those who need to punch a lot more I recommend a Lassco corner rounder for ~$150 like this one: http://www.factory-express.com/Paper_Cut......der.html

Chris,

I don't clearly see why the fact is made in China would mean it's crap. Of course, we all know that some products manufactured there are very poor in quality, but some are very good too! Depends the price you (wanna) pay. If one item is worth $250 in Europe or USA and if you want to pay $5 for it, of course, it's gonna be crap...

I've tried a corner rounder looking like yours and it did the job perfectly! There are many ways to round corner a card, in fact it depends how many you want to cut. For one deck once in a while, you don't need a dedicated tool, xacto, etc. will do the job. Of course, if you want to cut 250 decks per day you need professional tools.

Like his one for instance? http://www.kardwell.com/page/KII/CTGY/CARD-CUTTER-PED-MOD).

For one deck or two frequently, this one should have a nice ROI too: http://www.abcoffice.com/diamond1.htm

Just a quick chime in here.

I play to use this quite heavily. I'm a stickler for quality and cost doesn't much matter to me. I'm not rich but I understand the idea of amortizing which completely eliminates many of the lesser quality punches.

I did consider they Lybrary corner rounder but once I saw the unit silverking mentioned above, I was sold.

It's not about cost to me, it's about end product and based on a number of recommendations I am quite confident in my purchase. Also, the company producing the punch I chose is a sole manufacturer of punches. Various sizes, and shapes, they are based in North America, which is a plus but didn't really have much impact on my decision.

It has yet to arrive but I will be sure to let you know how it performs.

AMcD,
I looked at both rounders you suggested in my search. Kardwell's was a bit much for my purposes but I did strongly consider the Diamond Akiles, I had to consider types of cards I was going to be rounding and how to corner would be affected by various guides and such.

I'll let everyone know when it arrives and how it performs.

Here's the cheap one I'm talking about on Amazon:

http://www.amazon.com/Tonic-Studios-920-......&sr=8-18

Cheap as in under $12. Cheap as in mostly plastic. I bought it. It works but takes some fiddling with. I only needed it for a few cards. Pete Biro and I were working on a project that we thought might need a corner rounder but we changed the design and never needed it but we each bought one to use for a prototype.

Chris has some excellent information about working with cards on his site. I think if I'd seen his inexpensive offering before the Amazon one we might have ordered it instead.
