Well, it is a first effort at this kind of conversion. The scale is somewhere between 1/32 and 1/35; I've got another one slated to be IDF that will be closer to 1/32. For that one I built my own camelback springs and bogie carrier and had them cast in resin, but the results were only fair at best. I may yet return to the original R700 springs for that one. I burned out on it a while back before completing the front bonnet assembly. The wheels on this one are incorrect, having only five spokes, but at the time I had no source for the proper six-spokes. I found a solution for those for the second truck by way of an ESCI log trailer, a snap-fit- firetruck, rubber tires from a Hess oil toy, and a lot of scratchbuilding. They aren't perfect, but better than these 5-spokes. There is nothing out there for a 14.00 x 24 wheel and tire combo, which these rigs used. Same as the Mack M123, so I suppose you could use the axles, suspension, and wheels from Tank Workshop's kit if they would sell those separately. The trailer is based on an Israeli design, and is probably a little wide at a scale twelve feet.

Looks like you got your hooks in us, Greg! Now, reel us in with a fabulous finish!!! But, don't rush perfection.......we're patient! (Mostly) |

Seriously, that Mack combo has been gathering dust for the better part of five years. Looking at the photos I've still got some stuff to figure out, like where do I put winch controls? The images I was working off of are these:   Not much to go on, is it? I have a few more of IDF Macks, generally similar but with longer wheelbase, sleeper, and different winch arrangement. The black-wrapped things on the back of the tractor I've interpreted as something other than a winch with a tarp; those odd bulges don't look like winch lines or motors. But they could be, and I may have to revise that. Might make sense to the outer platforms and make an operator's station in the middle. Hmmm... |

Looks like the wheels on this one are the same as the ones you want to be cast up.

Looks like the wheels on this one are the same as the ones you want to be cast up. Not quite. These are an earlier version, and I no longer have the master pattern for these. I do have the masters for the fantasy tread pattern I would like to use on the Mad Mack, as well as a different set for a more realistic Mack DM895 tractor....I'm just fresh out of capable casters right now. |

You guys are something of a bad influence...just sayin'. You have me looking at these Mack DM895 projects once again though I haven't put a tool to either of them in at least five years. I've decided to rip the winches off the truck seen here to rework the area. The more I look at the image above of the sand-colored pair, the more I think I got it wrong. A winch or two on the centerline doesn't make much sense, especially since I can see the utility hose pole on the truck in the background, the storage and strain-relief fixture for the air brake and electrical lines to the trailer. Winches centered up would surely foul that when pulling a load aboard. I'm becoming more convinced that the black-wrapped objects on the outboard platforms are winches. The center area seems the proper place for an operator to stand with control levers. Slicing off the winches revealed a bit of modeling history, in that I've dinged up the deck surface and have to repair that. Back when I did this around 2010, I tried to keep material thickness at scale rather than building for strength so I've got holes to fill where now I would have surface divots at worst. Oh, well...live and learn. A shot of primer on the cab has revealed some blemishes to be rectified, so I'm working on that.
Then there's the IDF truck, elements are seen in rbear's thread on the Revellogram Mack. That one has a much better cab; I learned a lot from this first one that have made the second one better. But since I never finished the fenders and bonnet, I now have to stare at the parts and reconstruct what I was planning to do. That's a challenge, especially since I have two sets of parts in process. I was clearly playing with proportions, and I'm beginning to recall why. See, the brochure lists the overall width of the truck which varies depending on the size of wheels fitted. That ranges from 99" with standard 11.00-22 rims to 104.4" with 12.00-24 rims. Great, but it says nothing about the overall width across the fenders. The AMT truck scales at about 92", but I'm not convinced. The Mack line drawing on the brochure, which admittedly is something like 1/72 as printed, seems to show less of a tire-overwidth than a couple of inches. So now I need to figure out how wide I wanted to make the fenders. I never got an answer on that when I posted on the Big Mack Trucks forum years ago. Also, the front tread is listed at only 80.1 inches, rather narrower than the rears. But pictures don't show that the fronts are tucked well inside the fender line, but rather right out at the edges. I find it hard to believe that spacers were used. More puzzles to solve, which is probably why these two ended up on the unfinished shelf in the first place.
