Conrail GP15-1 build... JUST DO IT.

[P5se Camelback]

Ubetcha! Lacquer thinner (or Toluol) literally "welds " the two pieces of plastic together. I learned of that method of joining pieces of plastic together in the early '70's, working in the shop at my second job out of art school, in a consultant design office where we did a lot of medical equipment. On one occasion, we built operating prototypes of six small, sun glasses case sized patient-work heart monitors for a beta test. These enclosures were built totally from "scratch" from several thicknesses of sheet styrene (purchased in 4x8 sheets) from engineering drawings that we had generated. The build included cutting tiny pieces of "cove molding" to be welded into all inside corners and then when it cured and was hard, was scraped smooth with an radius gauge. We even cut "very tiny double coves" to be welded on (and again scraped with the Stainless precision radius gauges) to indicate mold parting lines. After everthing had been sanded "baby's bottom smooth" with 1200 wet paper, they were shot with some paint and all "welded" joints disappeared. The product halves looked for the world like production injection molded parts, especially after we silk screened all of the graphics (company logo, LED indentifiers, etc.) on the front case halves. It was all very cool ... and a ton of fun! What a cool job ... dress casually (jeans, denim shirt,) design and build cool stuff in a well-appointed shop with a couple other fun-loving guys who all really knew what they were doing and didn't complain about pulling all nighters about once a week to get the jobs done on time ... and get paid pretty well to do it! Who could ask for more? But, as usual, I digress!

But back to the thread topic ... I've been using Lacquer Thinner ever since - much cheaper in larger quantities than the Testors Liquid Plastic cement or the Plastruct solvent. And I just decant some of it into an old Plastruct bottle that's double-stick taped to a good sized plastic drink coaster so it won't tip over.
