Replacement "pick" roller for card reader

Yes, HP rollers seem prone to that ;-(. I have an HP9820 calculaotr where the internal printer platten roller had turned to goo and dripped onto the printer driver board, and even onto the main backplane at the base of the machine. Cleaning it up took nearly as long as making a replacement Getting back to your machine, is this a normal cylindrical roller, or does it have a flat on it or something? Thanks to recomendations on the MoHPC froum, I'ce found that 3M 'Cold Shrink' is a suitable material to make cylindrical rollers from. Put it on in layers (don't pull too much of the 'core' out). It grips well. That's what I used for the platten I mentioned. Before I was alerted to this product, I had conisdered casting my own roller using one of the 2-pack elastomers, like Devcon 90. The basic procedure is to make a mould, coat that with the release agent, coat the spindle with the primer, then mix the 2 parts of the elastomer and pour it in. The main problem ia that you're supposed to mix the entire elastomer kit in one go, once mixed you have 30 minutes to pour it, and you have to wait overnight before taking the part out the mould. Thus, yo have another go (something that I was sure to need to do), you'd have to use a new kit, and that gets expensive fast (I found that an elastomer kit + primer + release agent was going to cost over \pounds 100.00, the kit alone was over \pounds 30.00...) But of course you can make rollers of just about any shape that way, including oens with flats, steps, etc. I would have been more likely to give that a go if I'd had someody local who'd used said product (even if not for repairing classic computers :-)) who could have told me 'No, pour it more slowly' or 'You'll never get that mould to fill evenly' or whatever. http://www.hpmuseum.net? The site you mentioned is for handheld calcualtors mostly. -tony
