Making IDE and scsi cables?

Where is a good place to buy supplies to build regular IDE cables, 80 pin IDE cables and U160, U320 scsi cables?

So basicly any scsi cables and IDE cables.

Store bought cables will not do since this is for work and we have custom length cables for all the simulator systems.
 
My experience is that bulk ribbon cable for this kind of thing is pretty hard to procure, but the connectors are easy to source. Thus, I suggest buying pre-assembled ribbon cables and stripping the connectors off. You can then cut the cable to size and attach new connectors. This way, you also avoid buying a whole reel of ribbon cable from an obscure distributor in order to satisfy minimum quantity requirements.
 
I know I can get it at a Place in edmonton called active components. At least they used to. It's just a Electronics supply shop.

I just don't know how to crimp them. You can't do it by hand. The cable is pretty tough.

There are crimp tools specifically designed for 0.100" 2-row IDC connector housings like these, but a large, flat object like a textbook might work if you press slowly and carefully. I've had good luck with this method on 2x26 pin IDC connector housings--the larger housings should work similarly well.
 
The tools we have for making cables and funding shouldn't be a problem. Hell cards in the system cost more then my new car sometimes.
 
if anyone can post some links to get some connectors and ribbon cable i would love to make my own IDE cables.

i found a place some time ago that had cable but never did find connectors.

or even the name, specs, or dimensions of the conectors would help me out.
 
The connectors are called IDC socket connectors. The pin spacing is 0.100". For IDE cables you'd want the 40-pin (2x20 pin) connector; for floppy cables you'd want the 34-pin connector. Places like Digi-Key, Jameco, Mouser, Futurlec, etc. have these connectors readily available. The ribbon cable is harder to source. I basically gave up when I tried looking about a year ago.
 
depending on where you live, check surplus shops, here in toronto, there is a place called active surplus, and they had the ide cable in reels here for a while, off and on.
 
There wasn't any 68- or 80-conductor ribbon cable in that link.
 
note that you really cant make U160/U320 cables becuase they dont use ribbons... well, they do, but they have to have twisted pairs between connectors...

you can make UW (68pin ribbon, non-twisted cables) but they wont work @ 160 or 320 correctly
 
i didn't realize there was a tool to make those cables
i have always pushed the on by hand, i have yet to have a problem

meh, i always do it by placing a book on top of it, then hitting it with another book... cisco books work excellent for crimping (thats about all they have been good for so far)
 
www.mpja.com sells both the ribbon and the conductors. I'm lucky, cause a local computer store sells the ribbon by the foot :), as well as connectors.
 
Again, it only goes up to 50-conductor cable. The cable that MPJA sells is only suitable for ATA-33 and SCSI-1 and -2 narrow and wide cables.
