sorry if this is the wrong forum - couldn't figure out the right place for this one.

I do some low volume CD duplication. I print liner notes on nice, glossy paper and have a good system for folding and cutting. I now want to start printing jewel case inserts.

I don't want to use perforated inserts because
a) they cost a lot more
b) perforated edges look cheap (IMHO)
c) the paper does not give me the quality print I want
d) tearing out perforated inserts is a lot slower than a paper cutter

Printing and cutting is no issue for me - but I haven't figured out a good way to fold up the spines on the end. I can either fold before cutting or after - but cutting first seems to make the most sense as I'd need to unfold to trim the spines.

Anyone have a fast, accurate way to fold up 1/4" spines? I have a pretty well equipped wood shop, so making a fixture is certainly an option, if I can figure out a good design.

One of the concerned I've had is having a robust enough sharp edge on a folding fixture. As I was typing this message I realised I could use a scrap of Formica counter top - the laminate edge could be cut back at 45 degrees and probably give a good fold.

I'd love to hear your thoughts.
