[quote]QUOTE: Originally posted by hoscalelarry Thanks Gary, -- The dehumidifer will hold it to any humitidy I pick -- I was thinking about a 40% during the summer & it'll drop to 25% during the winter. That is what the other side of the basement has done the last 2 years. Will that be good for the layout? I don't know how I can keep the winter humidity up when furnece kicks on in those 'snow days' here in northern Ohio. -- Larry [/quote] If your house has 25% humidity in the winter, you should add, check or replace the humidifier on the furnace for your health sake. I believe it should be 60 -70%. If you lay track this summer, perhaps on a hot and humid day, by the dead of winter you might see gaps in the rail open up a bit. However if you were to lay track in the dry winter, by summer you could get a kink in the track if you didn't allow for expansion by leaving slight gaps (.015" - .020") in some sections (read Jim Hediger's article). It's not the track itself that expands and contracts, but the wood and homasote and in all directions. But it's ony a few thousands of an inch, not fractions. Also, if you solder your rails, don't solder them all. Allow them some movement at the joints. I don't know if you had read the Model Railroader articles on track laying so here's the link on [url="http://www.trains.com/Content/Dynamic/Articles/000/000/000/110kfhum.asp"]Laying flexible track without putting a kink in your plans, Going beyond the basic oval[/url] by Jim Hediger [url="http://www.trains.com/Content/Dynamic/Articles/000/000/004/379dcjrm.asp"]Quick and Easy Flextrack[/url] by Chuck Hitchcock While I'm at it, I might as well throw a few other ideas your way.
