fashion) and Masonite splines.\u00a0 All will be topped by Homasote roadbed.\u00a0 I&#8217;ve used Homasote for many years and I&#8217;ve always had good results with it.\u00a0 I have a single sheet and also plenty of scraps from my old layout that will get used, but plenty more will be needed.\u00a0 A friend has several sheets that didn&#8217;t get used on his present layout that he&#8217;s willing to let go, and the last time I checked, there was a lumber yard about 60 miles from me that stocked it.\u00a0 Hopefully they still do.<\/p>\n<p>The two major complaints that I&#8217;ve read about Homasote over the years are expansion\/contraction from the humidity, and the dust generated when cutting it.\u00a0 I&#8217;ve never had significant problems with it in the former even though I don&#8217;t bother to seal it.\u00a0 As for the latter, I have never let the dust deter me.\u00a0 I just vacuum the area immediately after cutting to minimize the mess.\u00a0 I&#8217;ll try to do major cutting outdoors and I&#8217;m also going to try using the knife type sabre saw blades if I can ever find them.\u00a0 I&#8217;m told that they greatly reduce the dust produced, although they cut a good bit slower.<\/p>\n<p>On my former layout, after the track was down, I had gone back with a router and cut bevels on each side, creating the ballast shoulders.\u00a0 I did the cuts freehand and they came out rather well, but the process was slow and tedious.\u00a0 I&#8217;ve read an article from a fellow that makes his own Homabed (a commercial Homasote roadbed that has been planed down for consistent thickness, and has beveled edges) and I&#8217;ve thought about trying to produce some small amount of that to see if it&#8217;s worth the effort.\u00a0 The commercial Homabed is quite expensive and frankly, is out of my budget.<\/p>\n<p>For the yard areas, I&#8217;ll just laminate sheets of Homasote to the plywood sub base and the track will not have the ballast slopes.\u00a0 I want the yard and industrial trackage set in a mixture of ballast and dirt, really buried into the ground.\u00a0 I can cut some shallow ballast slopes or small ditches along the perimeter of the yard area using my router as I&#8217;ve done before.<\/p>\n<p>I&#8217;ll post more comments when I get to that step in the work.<\/p>\n<p><em>-Jack<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>As the basic frame of the benchwork progresses, my thoughts are turning to the next step which is the track structure: sub-roadbed and support risers, and the roadbed itself.\u00a0 For the sub-roadbed, I plan to use a mixture of flat &hellip;
