I used to sell proximity switches for a living, and one of my customers made greasers. The idea was that the proximity switch would detect the outside of the wheel flange and operate a compressed-air solenoid that squirted a dose of grease onto the inside of the flange.HI Pete thanks well ive learned somthing today dint know that

Chris, Walthers Model Railroad catalog (it is on-line) is my USA source for most detail building supplies. Most of the piping, ladders & cages are from there. The one elevated tank on three legs is a kit from there as well. All the rest are from "found objects" ( the smaller "welded" pipe is from the little flags the lawn guy throws in the ground to warn you he just poisoned your lawn) my wife calls trash. I'll check on the maker of the larger cage kit as it would work for 1/72 as well. That is also where most of the Industrial Yard buildings & rooftop details came from. The commercial vent kit would prolly work for you also. PaulE
HI PaulE THANKS for your info on them ladder safety cages an yes I found up theThose large ladder/cage kits are easily extensible. Unfortunately I didn't save the wrapper or the instructions, but I'm sure they're still available. PaulE
