Adelie; <br /> <br />Thanks for the additional comments. Your radii are somewhat larger than I am planning. Your Rmax is about double mine! I am only planning about 200mm for the inner and 250mm for the outer ( um, about 8 and 10 inches ) because I am using small rolling stock. The loco is maybe 2 inches. The freight wagons are barely any longer (most are 57mm long) - so I can get away with a TINY radius! I may go larger, just so I can keep the grade lower. <br /> <br />I suppose I keep throwing in the ideas about change because that is a big part of what people pay me for. Many times we have found new construction techniques or radical approaches to our design work, and ultimately not a few patents, by saying "why". It is said by some of my contractors that if they don't ask why often enought hey will be asking why they arent getting any more work from me. <br /> <br />As for the ease of working it, I totally understand! <br /> <br />Before I left Australia I had a table saw, band saw, scroll saw and all the power tools you could want and a workshop to put it all in. Not to mention the lathe, small mill, drill presses, gas, arc and MIG welding etc. But I also had a place to put everything, I had a 40ft x 20ft workshop. Here? Well, I suppose I have about 13ft x 8ft for ALL my workshoip activities which includes art and craft for my wife and daughter. Hence pretty much EVERYTHING is contracted out, which is fine when clients are paying but a pain when I want something for myself. So I get small 'favours' done for me by the jobbing shops I use. <br /> <br />My laser cutting guy said he can do ply, so when I have some tiem I will do a set of drawings and we will see what we can do with some 6.5mm ply. Might just take the same drawings and run a sheet of foamcore then compare the two. <br /> <br />Many thanks for the ideas, <br />John <br /> <br /> <br />
