    Default A Borg Dozer on a 1:87 MTH 60' HTTX Flatcar

    Have been working on this the last few evenings, a Norscot D9T HO scale Dozer on an MTH HTTX 60' flatcar. MTH seems to be the only brand that makes this particular type car, and with an extremely high degree of detail. The only pity is that they opted for plastic decks, rather than like Intermountain did with their real wooden decks on the OTTX ones they make.

    The D9T, I have had dismantled for some time, an "interesting" project in itself. Here is a prototype picture of what I'm aiming at

    The Flatcar being used is TTX, I weathered the wooden decking by brush painting with Polyscale Reefer Grey, thinned a bit with 70% isopropyl Alcohol
    (sound just like MR mag, eh). Once dry, I rubbed some lamp black pastel, using a medium stiff, short bristle brush, along the "boards" to enhance the gaps and bolt heads. Went a little heavy on this, but was able to restore the greyness to the timber with a similar light grey pastel and soft brush. The metal groves in the decks where the tiedown chains lock into, I painted with a rust coloured acrylic I mixed up from various artists paints I have, to a color I liked, using a thin edged soft flat brush, which kept the paint in the groove much better than a small round tipped brush.

    The Trucks were removed and washed. They have working springs and rotating caps on the axle ends. Unfortunately the axle extensions pass through the sideframes, and the caps press on. Because the sideframes can move up and down on the springs, they are not fixed to the bolster. I did take the caps off one axle and attempted to remove the axle/wheels from the sideframe, but changed my mind in case everything came apart. Glad I did, getting those tiny, tiny, tiny caps back on was heart in mouth stuff. So wheels and sideframes got painted assembled. Was fairly easy in the end. After adding a bit of "Vallejo" dark rust wash to various parts, I gave the sides and bottom a dusting with the Frosted Glass paint I used on my Gravel hoppers and remounted the trucks. Another interesting difference to the majority (or all) other brands, the spigots the trucks pivot on are metal and separately applied to the car base. They appear to be those split spring dowels you would find being used in engineering for aligning two sections of a casting together.

    Some photos of progress so far

    The chains are yet to be secured to the grooves using the ratchets supplied with the flatcar, going to be tricky. More chains to be used to secure the other parts as well. A couple more pics to follow.

    Ah, and before I forget. Why the "Borg" reference? that's because this is "one of five".

    Sweet Toot, I'd say you nailed it!
    This has been on my list of to-do's for some time.
    I must say that's a strange way of tieing it down tho, never seen that before.
    Hard to dispute actual prototype pics tho, eh?

    Yes, the chains over the tracks doesn't seem a very secure method, although tightened well, it probably is. Odd that there are no provided tiedown brackets on the machine itself. Here's another of the larger D10T showing 4 chains per side, wish someone had done them in HO as well.

    These are D10's as well I think, note the overhang of the Flatcar sides

    The satisfaction of a detailed load, priceless.
    Good job Toot.

    Anybody notice there were no visible chains on those D10's? in the last pic because of the tracks overhanging. They seem to be secured by some special steel brackets (rust colored), apparently bolted to the tracks and presumably locked into the tiedown channels instead. The D11 range is the largest Caterpillar Dozer, so maybe that's what these are.

    This picture is taken from the Transportation Engineering Agency for Military Surface Deployment and Distribution Command.
    This is the tie down procedure for a D7 dozier. It appears to have tie down channels out the outside edge of the flat car as well as a second set of channels near the middle of the flatcar.

    Thanks for that diagram Ken, the military certainly seem to go with a more secure method. Would depend on the Dozer size if the blade was still attached, the model ones hang out about 7/16" each side. Doing a bit more research, found this y/tube vid which particularly near the end when the train stops and the taker gets some close up shots. Confirms that from ex factory there are no other chains visible apart from those over the Dozer's tracks. Confirms these are D10's too (nice, clear still shot) and even of the delivery sheet attached to the radiator. I might get as far as a yellow piece of paper with some squiggles on it.
    Fast forward 1:00 min to see train
