Tony and others- The dreadnaught ends I purchased from Richard's table at the Eugene NMRA '87 event were made of poly ester to my recognition. Lots of early resin casting was done in Epoxy, such as the exquisite 'O' Scale drednaught end boxcars and one-piece interurban cars made by Bill Clouser. He reportedly bought his epoxy in large drums and when good poly urethane resins came available Bill stuck with what he knew. Tony wrote- Ben is entirely right, and I appreciate the enlargement of the topic. But it’s worth mentioning that the superb sides made for the War Emergency box car were from a master made by Lloyd Keyser. Richard had reached out to a number of top modelers for help with the projects. And BTW, most of the smaller castings he provided weren’t resin, they were epoxy, a material he had learned to work with, long before many of the materials and tools we now take for granted with resin were available. TT........... BTW; Byron Rose did not make the 70 ton flatcar patterns. I think these were also built by Lloyd Keyser. After Richard was done being a resin caster he passed along the flat car patterns to Byron who did some upgrades and made an underframe. -Andy Carlson Ojai CA |

I think this is right. I wasn’t sure it was Lloyd for the flat car, though I knew Byron got the master afterwards. Greg Martin had said he wanted to make some of the parts available again, simply casting them in resin, but to my knowledge never did. Maybe someone more closely associated with the Shake ’n’ Take projects knows more. Tony Thompson |

I based my statement on Byron's reissue of the kit, and certainly didn't intend to short Lloyd regarding credit. Ben Hom |

Polyester... Polyurethane... same purpose, but different properties. On 2/9/2023 3:20 PM, Tony Thompson wrote: Richard always said they were two-part epoxy. I guess that is a polyester resin too? I'm not a chemist. --

Westrail and Byron did 50 TON flat cars. Sunshine produced the 70 ton AAR flats (one of his more difficult kits!) which was made obsolete by the Intermountain model. There was (or is) a small resin caster in Colorado (I think?) who produced a 70 ton resin AAR kit. On 2/9/2023 3:33 PM, Benjamin Hom wrote:
