Goonie's Sci-Fi thread
« on: May 24, 2014, 03:51:32 AM »
Because I've got quite a lot of unfinished or planned to do Sci-Fi models, I would like to create a single thread for them.

First one would be Martian HEMMT escort truck, as I have mentioned in this topic http://beyondthesprues.com/Forum/index.php?topic=4280.0 I'm going to build escort truck for convoys transporting supplies from space port to the mining facilities on Mars.

As a base I'm using Italeri "HEMMT Gun Truck", with AFV Club "Remote Weapon System" on roof gun port. Original tires will be replace with Lego balloon wheels (they are more than 2x wider than the original + only 3 mm bigger in diameter than original one) and finally on the back of truck I'm going to scratch build some sort of autonomic rail gun (similar to Phalanx CIWS).

Whole idea for the model is the result of visiting this site: http://www.ga.com/railgun-systems and large disappointment when I had discovered that HEMMT with Phalanx system already exists ;)
After all I have also red somewhere, that Oshkosh is trying to adapt HEMMT design to almost any possible task, so why not use it on Mars?  :D
After a lot of reading on problem of adequate propulsion system for vehicles on Mars I've decided to ad some containers for liquid O2 and other gases required for effective burn of methane in engine. Next problem would be an adequate amount of power which rail gun will use during combat (as I've noticed its quite unpractical at the moment: http://www.janes.com/article/28774/ausa-2013-general-atomics-unveils-blitzer-land-based-railgun it looks like that most space is used by energy generators/fuel cells), so I've decided to scratchbuild some sort of fission battery. About 2 years ago I've red in "Focus" that some corporations are trying to create nuclear batteries for developing cities, so why not decrease it in size an implement on vehicle in future, especially that on Mars there is almost nothing (except possible Human settlers  ;) ) that could be harmed in any case of radiation leak.

and here are some photos:

2. building process:

original poorly detailed engine


same engine after adding a few more details:

Those lego wheels with the inserted hubs look awesome! They'd work for many projects, post apoc and sci-fi.

The wheels do look great, but I bet it costs a fortune to buy a set if you can't pick some up 2nd hand.

To be honest i bought all of them for equivalent of 10 USD on some ebay like polish portal (yellow are much cheaper than white od dark grey).

Once again thanks for kind words :D
Anyway I will have to find some way to get rid of "Lego Group" markings on tires. It looks to strange even for my standards  ;)

Oh and I've got one importatnt question about some element of HEMMT. Is it an air filter (part marked red on photo below)?

Finally I've made some progress with the model so here are few photos of it:

1. Early attempts to fix the whells:

I turns out that original suspension is a bit too small for them, distance between whells was minimal + pivots was to fragile and they tend to bend somewhat when I had mounted the wheels. Later I've decided to modify the suspension in a manner that whells are mounted now on Lego pins instead of original pivots:


Still it's not perfect, but in my opinion it looks much better now and way more solid.

2. In mean time I've thought that the asymmetric position of main armament would be much more interesting than the previous one:

That black part behind gun platform is some protection cap from old CPU and works perfect as socket for nuclear battery, speaking of which:

(original petrol tank is under modification to resemble a bit more the gas tank)

3. Progress so far:

Looking more interesting as you progress, Goonie. :)
