    Thanks Paul, I have noticed that procedure helps. 1/32 model train car mold procedure-img_0564.jpgHere are some more parts for the truck, still mocking up. *I combined the spring cross bars with the mounting plate, so it makes it a little easier to assemble. Bob.

    Bob,
    The trucks look impressive. Looking forward to seeing these on the heavyweight passenger cars.

    I have been trying to get the perfect shape for the F cab windshield and I made a pattern for a mold. The shape has been scaled from the full size to 1:32 and is made with the seal. I loaded the program on my Anilam controller and had to delete all of my other programs just to get this file on my machine, about 4000 steps.1/32 model train car mold procedure-img_0568.jpg Here is the beginning of the operation. Bob.

    Here is what I have been doing in the last few days. I made a mold of the heavyweight doors so that they will open and be a split door. *I am still trying to make the perfect E and F series windshields. *I am trying to make the windshields, so that I may retro fit them into any one gauge E or F series loco. *I am designing them so that when installed in the loco, there will be no glass to make it easier for painting and then there will be a ring in the shape of the windshield, to be installed from the inside to hold the glass in. *I am using .020 Lexan for the glass, also making the side windows for the loco, and here are some pictures of the patterns and molds.

They came out just like I wanted them to. *I have to draw just one more part to complete the assy. then I will attempt to install them in an MTH cab and the other cab that I made the mold for. Here are some pictures. Bob.

    Bob,
    I like your clever use of the "scoring" method with the CNC inscribing technique. This would be very precise for any type of model making.
    Thanks Paul

    I should have described the cutting tool a little better. The blade in the cutter rotates 360 degrees and protrudes about .005 in. The blade is mounted with a spring loaded pad and moves about .250 in. for uneven surfaces. The blade was purchased at a vinyl cutting supply store and adapted to my tool. Thanks Paul. Bob.
