With all the "stuff" being done today, why not these things!
1- better scale tires made from styrene. If the Armor Model Co.'s can do it, why doesn't AMT or Revell or Mobius do it?
2- I know it is a cottage industry but why can't resin vendors keep their web sites updated and current as to stock availability??
3- when are we going to get models of construction and farm tractors?. Not hay-baler or manure spreaders, things like those great big multi- wheeled John Deer's and some excavators or bucket loaders and such?.
After a while I personally get tired of seeing more Mustangs or Chargers or 32' Ford' and whats with all those NASCAR re issued smoothed over and re packaged. Let's try something daring and different? Just the results of a recent conversation with some of my modeller buddies after a night of six packs.L.O.L.
1) You say "better" scale tires made from styrene: Short of making the tooling to do that in styrene in multiple segments (think of slices of a pie here!) there is no way to get detailed tread on a hard styrene tire. Bear in mind that few military tires have the multitude of relatively small tread grooves, many running concentric with the circumference of a tire. Molding them in hard plastic will require multiple mold sections in order for the tire to come out of the tooling, and even then there would be compromises, as hard styrene will not pull out of a mold if it has to come out "sideways" against the raised detail in the steel tooling without damaging the tire, and badly wearing the tooling.
2) As a former resin caster, I can say, unequivocably, that resin casting is a full time job in and of itself--actually more than full time. Maintaining a website itself can be a full time job as well. Pay someone else to keep up the website? Well, that doesn't come cheap either.
3) Model kit of construction and farm equipment? That's been tried, several times over the past 60 years, as styrene plastic model kits. While I am with you on this one, those kits never sold at all well for their manufacturers. When a manufacturer is considering a new plastic model kit subject, the sheer cost of developing that kit, creating the tooling, and even producing it simply demands a large volume of sales from each kit--with a newly tooled kit, it can take upwards of 100,000 units SOLD just to pay back all the upfront costs (this has to happen before they make the first nickel of profit on the product).
Another issue here is scale: With farm equipment, there is already a very large hobby in collecting diecasts of that. As one might expect with our model car "love" of 1/25 and 1/24 scales, farm toy collectors have their preferred scale(s) which are different: 1/64, 1/32, and 1/16. 1/25 scale farm equipment to them is a "bastard" scale! With construction equipment subjects, it's all over the map, given the sheer size of such machinery in real life. Complicating this is the apparent lack of interest in the model car hobby for model kits of construction equipment sufficient enough to generate the sheer volume of sales necessary to make any money for the company(ies) who might enter that field in "our" scale. The Ertl Company tried that, in the mid-70's, with the likes of John Deere and Massey Harris tractors, and implements to go with them--they literally "died on the vine". The only reason AMT/Ertl reissued the two John Deere tractors in 2001 was that John Deere dealers often have "boutiques" in their dealerships, selling all manner of collectible JD items. AMT/Ertl released those John Deere tractors to the general hobby shop market, and many hobby dealers ignored them, sensing a lack of market for them (I bought one of each JD tractor myself, BTW, but have yet to build either one).
The model companies who supply our hobby do have a pretty good hand on what subjects will sell--cars such as Corvettes, Mustangs, '57 Chevies, even Nascar Cup Cars do sell, and in fairly large numbers--that's why you see so many of them over the years--if they know that certain subjects sell very well--make more of them! If not, then not.
