Edward Traxler is someone I’ve read about for a while. Only recently did I visit his website. Where I found today’s interesting set of resources.
Site 1: Edward Traxler’s The Deep River Railroad – PDFs and PPTs page
It’s just what the name says folks. A few really good clinic presentations and PDF files for building all sorts of interesting things. Plans for loading ramps, piers, and links to other resources for the interested.
Site 2 – as for site 1 – Building cardstock models the modern way
Also on Edwards site is a great tutorial on building using cardstock (thicker grades of paper). Both a PDF and PPT file are available for download and there is an overview on the page in the link above also.
