You could use cardboard rather than wood if it’s just a one time job. ( or scan the tape into files and process digitally ?) We're so close, I wish someone would figure out a way to let a contemporary office scanner like the Fujitsu ScanSnap to handle paper tapes. Reliable feed mechanism, nice scanner, just needs a little software and maybe a guide. And a way to re-spool the tape. Darn, just got complicated. Same thing for a new way to read a magtape. You'd think it could be done with a universal read head and some software. Nine years ago I visited http://www.comco-inc.com/ , perhaps one of the last sellers and refurbishers of 9-tracks. I dropped off three 9-tracks I didn't need. He seems to be surviving because oil survey companies still call and are willing to write five-figure checks for particular working hardware. - John
