Small gears Message #1 Posted by Vassilis Prevelakis on 13 June 2006, 2:55 a.m. This showed up in the classiccmp.org mailing list, so I am copying it here because it may be of interest to readers of this forum as well: From: "Robert Feldman" <r_a_feldman@hotmail.com> Subject: Re: atari printers - gears [There is a] shop in Letchworth Garden City, Hertfordshire, that makes gears for model railroad locomotives [...] Gear Services (Letchworth) Ltd., The Wynd East, The Wynd, Letchworth Garden City, Hertfordshire, SG6 3EL United Kingdom. Tel: +44 (0) 1462 685327 Fax: +44 (0) 1462 677821 Their Web site is http://www.ultrascale.co.uk/ggs0001.php They can produce the following spur gears: 48 DP from 12 teeth upwards 60 DP from 12 teeth upwards 64 DP from 13 teeth upwards 72 DP from 13 teeth upwards 96 DP from 18 teeth upwards 100 DP from 15 teeth upwards 0.4 MOD. from 21 teeth upwards 0.5 MOD. from 15 teeth upwards The price for a small gear (e.g., 15 tooth 100DP) is /Pounds 1.11, so it should not be outrageous to have a custom gear made.

How to make your own gear Message #2 Posted by Klaus on 13 June 2006, 3:07 a.m., in response to message #1 by Vassilis Prevelakis One gear of my sharp CE-150 plotter broke, and I managed to make my own. Just repair the broken gear with some glue, and press it into a soft material (like clay). Then pour some epoxy into the footprint, and you are done. My gear is about a year in use now, and it still works! However, having your own gear made is certainly better.
