josef posted:Just out of curiosity, do any of the other scales HO, S, and N have problems like this? My good friend and neighbor who is moving this week and had a sale on his HO equipment and was at one time into O scale when asked if he ever had any electronic or zinc problems in his 15 years of HO modeling, said he never had any problems as he read and followed on Forums. His layout was in the garage with only a fan to cool him when operating.
Yep - I noted earlier N scale with zinc pest issues with Rivarossi 1960s/1970s steam engine and diesel chassis. My brothers had a HO Rivarossi 2-8-0 that had its tender chassis crumble (tender had the motor mounted to it and the frame just fell apart - those were all made in Italy).A recent issue Intermountain N scale SD45 from China I recently obtained had its chassis disintegrate when I took the engine apart to service it. Prewar Flyer 3/16ths O gauge is notorious for being afflicted by Dorfan’s Disease - I’ve had first hand experience with all of these. Unless the zinc is kept as pure as possible the possibility exists for zinc pest to occur - it doesn’t show up immediately and so you never know when it will show up. Maybe plastic or brass shells over a chassis with a slug of lead tor weight is the way to go.
