Title: 1/35 HEMTT Explorer
Post by: Frank3k on August 05, 2024, 10:41:22 AM
Inspired by Weaver's post of an AI generated HEMTT Expedition over at WhatIf (https://www.whatifmodellers.com/index.php?topic=40246.msg1047760#msg1047760) I decided to try and make a "realistic" HEMTT exploration vehicle. The back story in my head takes place after the inevitable and chaotic collapse of the Russian Federation and an attempt by NATO and others to get into the former Russian vassal states and ascertain what weapons systems were still a threat, disable them on site or mark them for future destruction. That may change, though.

I have an Italeri M977 HEMTT (https://www.scalemates.com/kits/italeri-0292-m977-hemtt--110045)

(https://www.scalemates.com/products/img/0/4/5/110045-54028-25-1080.jpg)

It's an average to good kit, withe the advantage that it's in my stash and not terribly expensive.

This is my preliminary design; I was tempted to try making the AI generated version, but I don't want this project to drag on for months on end:

(https://i.imgur.com/d6HOk9n.jpg)

The gray areas roughly define the living/working areas. I'm going to make this an electric truck with dual motors feeding the original transmission, and a diesel generator to charge the batteries and provide electricity. I'm guessing the range would be around 600-800KM, about 1.5x the standard HEMTT range.

One issue with the kit is the downright anemic tires. I've been lucky to have figured out the magic of making tires in CAD, so I took the design of the generic HEMTT Michelin tires and cranked it up to 11 (or 10.5).
I printed the tires on my new (to me) Saturn 8K resin printer, which hasn't been fully dialed in yet, but the results seems to be OK.

New printer, new resin I haven't tried before (Siraya Tech Fast Navy Grey) and I managed to drop the tires before they were cured, so they have surface scrapes and a couple of dings. Still, not bad:

(https://i.imgur.com/ffHWj7U.jpg)

One of the dinged front tires:

(https://i.imgur.com/tdHj8WP.jpg)

Compared to the kit tires:

Test fit - the tires (especially the front ones) aren't pushed in all the way, so they're a little wonky:

(https://i.imgur.com/uQx8IvA.jpg)

I modified the cabin to remove the engine cover. The front of the cab will still have one of the radiators, though.

The new tires/wheels look fantastic Frank.  The slight/subtle increase in dimensions really makes the things look more "rugged" than the original kit parts. 

Where are you going to place your auxiliary generator to charge your batteries?  Also where are you putting your battery banks?  Inquiring minds wish to know more.  :smiley:

That's sort of the inspiration; I like the exterior details. I'm using an ICM KUNG shelter (https://www.scalemates.com/kits/icm-35010-truck-box-military-vehicle-kung--1402698) to get ideas/dimensions, even though it's smaller than the space available on the HEMTT

I was thinking of putting the aux generator either at the rear of the vehicle (reducing the "office space" by a bit) or where the current engine is, only sideways to allow for a passage from the cabin to the shelter.

the batteries will be in the space under the shelter - it looks like there's room for 2x the number of batteries in the typical EV semi. I won't put that many in, since that would put the batteries at around 15,000 lbs. So about 1/2 - 3/4 the space will be for batteries. For the projected range, the diesel generator can charge the batteries and make up for the difference, so maybe this is more of a hybrid EV truck.

It is not about the PowerPoint presentation, it is about the number of people that you can torment with the presentation in one room.  The more that suffer through the presentation together the better.

-- The shelter component looks like a great idea so far.  Just like to add to that, Italeri did offer a nice (yet generic) S-280 type electronics shelter a few years back (2001) that would also be an excellent candidate for your HEMTT.  Especially if you could combine two of the things together end to end.

-- With the switch to electric motors would there not be space available behind the truck cab for the generator?  You indicated that there would be two motors (one for each set of 4 X front and 4 X rear wheels).  With the removal of the engine from the location behind the cab there would be enough space available for the generator unit to occupy that area?  Putting the generator unit at the rear would also be an excellent choice as it would/could replace the hydraulic lifting apparatus that is mounted at the rear of the vehicle.

This is what I designed today, based roughly on the  EPS 40kWh diesel generator (https://www.enginepowersource.com/generators/mobile-diesel-generators/45-kw-diesel-generator-details/). In 1/35 it's 62mm x 22mm:

(https://i.imgur.com/3TgNgic.png)

It fits over either side of the engine platform or in the middle, where the old engine would have been. The electric motors would be in the bay under the generator. It would also fit on the crane platform as well,
 although at about a ton, it should probably go on the engine deck

It's an expando van (like what they mounted on the old 5 ton trucks), it compresses to 1/3 the width when on the move.

I really should pause to calibrate the printer, especially now that I've used up this old (but excellent) resin. This is the generator - it has some printing flaws, but good enough for now:

(https://i.imgur.com/UHrn10Q.jpg)

Closeup. I sanded off some of the supports, hence the dusty appearance:

(https://i.imgur.com/JXrQ6za.jpg)

I have to rethink the location and layout of both the generator and office space.

Also, with all the tires on, this is a very heavy model. I have to rethink my approach next time I make tires this big (I could hollow them out, or make the tires and wheels/hubs separate)

I printed out a couple of generators, large electric motors and some motor supports. The generators came out OK; I started some pre-processing on them before I paint them tomorrow.

The generator in the middle was printed with 30 micron layers; the other two (and the motors) in 50 microns; much faster and the loss in resolution is minor. The motor in the middle lacks motor supports (on purpose):

(https://i.imgur.com/5s1CMgg.jpg)

Here's a closeup of the control panel for one of the 50 micron generators. The keyhole is just under 0.6mm in length:

(https://i.imgur.com/yhQw9X9.jpg)

The engines are completely made up; I used images of large electric semi engines that I found online for inspiration:

(https://i.imgur.com/H3ZjmI9.jpg)

The two smaller boxes are for cooling (oil, I assume).

Engine end. You can see some printer artifacts, but they'll disappear with some light sanding and primer (maybe only primer):

(https://i.imgur.com/3RLU1WQ.jpg)

Underside with the engines tacked in roughly the correct position:

(https://i.imgur.com/sMjCaPw.jpg)

 The white "battery pack" is from the Space: 1999 Nuclear Waste Disposal Area 2 Diorama Set (http://"https://www.scalemates.com/kits/mpc-860-nuclear-waste-disposal-area-2-diorama-set-with-1-24-scale-moon-buggy--1107833/inthebox") it's a good source of parts.

Thanks - at times it's 100% a PITA, especially the cleanup.

I'm thinking of replacing the former engine platform with a 3D printed slab (because it's easier to print a square 1mm think slab of plastic than it is to cut it neatly) that extends (or at least matches) the cargo area height.

@Frank. 

I was going to suggest the same option as Robin but opted to keep my pie-hole shut.  But as Robin said, adding the 20.0' ISO Container would be a quick alternative to the build a box from scratch. 

My own experience with the Italeri 20.0' ISO container had mixed results.  The roof and floor are created from two near-identical parts on two separate runners and getting the things to align properly when glue was applied caused some small hiccups for me.  The resulting floor that was created had a large obvious seam right across the middle of the floor.  Same problem for the roof but not much can be done about the top.  I added some ICM PAG-14 airfield plates to cover the seams on the floor and have something that resembled an actual floor.  The 1/1 scale 20.0' ISO container in front of my residence has a very crude floor so it was not too far off from what I added to the 1/35th scale Italeri ISO container.  I also have some of the Trumpeter ISO containers in the stash but have yet to actually do a close inspection of the contents. 

Also, love the GENSET and tires that you have printed.  How long would it take for you to print up some GENSETS and wheels?  :smiley:

I'll try it - at least the walls. I was planning on covering up the roof with equipment, anyways.

At 30u resolution, about 5 hours, each.

At 50u, about half that. I can send you one (or two) of the spare generators and a bag of wheels that failed. The resin I was using was old, so I risked using the parts as their own "calibration" so some of the axle connections are defective. Easy solution is to either drill out a new one or glue a plate with epoxy and add a new axle hub.

I should get some of my favorite resin today, since I still need to print more parts.

I have the Trumpeter 20 foot container, and it's almost a snap tight kit - and very heavy. Here it is on the back of the cargo floor:

(https://i.imgur.com/9VMy5Em.jpg)

It looks good, if a little tall. The main problem is the weight; the 20 ft container weighs almost as much as the rest of the HEMTT shown here. With the resin tires and motors, I'm afraid that it may break the axles or the spring supports (it's that heavy).

I Also printed a flat platform that sits (or will sit) level with the cargo floor.

Here's the lighter and smaller ICM "KUNG" truck box:

Eisenhower's post-WW2 autobahn system had height, width and (bridge) weight restrictions based on the MBTs of that period.  I'd have to dig but 14'6" seems to be a bridge clearance height that sticks in my head (although there are Route Calculators one can consult to see where the Low Clearances are these days).

As one of the components of the National Highway System, Interstate Highways improve the mobility of military troops to and from airports, seaports, rail terminals, and other military bases. Interstate Highways also connect to other roads that are a part of the Strategic Highway Network, a system of roads identified as critical to the US Department of Defense.[52]

Fast forward 70 years, if this is a .mil project those constraints would still be in play?

That said, what's the scalar height of the Trumpter 20' container? Maybe you could shortenify  it?

The ICM and Trumpter box bodies could also be Swoppet builts (held in place with tiny pegs?)

The wheels are solid resin and there's no easy way to lighten them; it would be easier to reprint as hollow, but i'm not going to do that. The Trumpeter 20 footer has a lot of material - the corrugations add a lot of area and mass.

The 20' on top of the H?EMTT (with the new wheels) scale out to around 16'/4.9 meters. It would make a mice target, plus making driving in a cross wind difficult, even with the added weight.

I think I'll go withe the shorter (but lighter) truck box and pimp it out.

Just my $0.02 worth. I’d go with the truck box and lengthen it as much as you can with still leaving room for the generator. The connection to the cab is a good idea.

I've made progress - but it doesn't seem like it. I've been folding PE for the cockpit cabin and in general finishing it up. Here's the cabin with some of the PE installed, before a coat of primer:

(https://i.imgur.com/wdQiiKC.jpeg)

I printed a small riser wall extension for the truck box, since it was too low for most of the standing figures I tried to put inside. I also leveled the "generator platform" to bring both platforms to the same height at the cabin.
I had printed a new back wall for the cabin with two hatches, but they would have been blocked by the platform at its new position. It may look like there's plenty of space where the current rear windows are, but there isn't. Instead, I used some spare hatches from the AFV Club M151 RWS kit (by itself a great source of unused parts) on the cabin:

(https://i.imgur.com/EZg8I2l.jpeg)

I also swapped the box and the generator. Not sure about this layout:

(https://i.imgur.com/9VUb7sL.jpeg)

One annoying thing about this ICM truck box is that the AC unit isn't included! I ended up printing a generic AC that I tacked on to the back of the box.

If you move the KUNG until the door is over one of the wheels you could have a groovy little fold-down ladder
Title: Re: 1/35 HEMTT Explorer
Post by: Frank3k on August 26, 2024, 03:14:06 AM
I'm leaning towards Dr. Yo's suggestion, since the two spare tires will be around 1400lbs/635kg which is around the same weight as the generator. They can go in the space behind the cabin, which already has a tire crane.

The KUNG has a step ladder for that hatch. I just need to move the box back a bit

It's definitely a game of Tetris, but with only a limited range of positions!

Today was another day of a lot of work, but not much progress to show.

I made two 3D printed laptops and a 24" monitor a while ago. I painted the screens with Molotow chrome paint, and when dry, I added color laser printed decals. The panel in the middle is just a a decal of EV status display I found online, sandwiched between a clear sheet and a piece of white plastic. All of these items look better at normal viewing distances, rather than zoomed in like this:

(https://i.imgur.com/YZK225f.jpeg)

Placement in the cabin. It's nowhere near finished; the radio (with the light blue screen) will probably be moved and so will the M151 RWS joystick. The 24" monitor is on a (working) swivel arm. The black box under the small table in the middle is actually the power supply for the radio, here used as a controller box:

(https://i.imgur.com/05HqVsB.jpeg)

As for the rest of the vehicle, I'm adding the electric motor wiring and coolant lines. The two spare tires weigh about as much as the generator (1400lbs/635 kg) so if I place the two pares behind the cabin they can balance the generator.

I painted most of the vehicle with a coat of Tamiya NATO green (that's not going to be the final or only color). I also painted the batteries, motors and the coolant and electrical distribution boxes:

(https://i.imgur.com/Mb9nSKq.jpeg)

The motors are painted with AK Interactive Atom Aotake blue and the batteries in  AK Interactive Atom Aotake green. There are some gaps and build issues with the batteries, but they'll be mostly hidden. I modified he kit's transmission transfer box to convert it into an  electrical distribution system for the motors. The coolant system box is a random plastic part. The coolant lines are from a Hasegawa 1/35.

I'll do some cable management before I join the two sections.

I printed some parts: Antenna mounts that I found online (see a couple of posts up) and some fire extinguishers I drew up (I was tired of making them out of sprue and bits of plastic). I also combined the radio unit (receiver, power supply, external speaker, handset) and drew up a camera ball. I think I'm set with antenna mounts, radios and fire extinguishers for a while.

Here are the parts off the supports and washed; they still need some cleanup:

(https://i.imgur.com/g7YPLDM.jpeg)

The thin wire for the large antenna mounts printed in most, which is surprising since they were very thin and I didn't add any supports. I made four types of fire extinguishers - small, medium and large (with and without mounting straps). The ones that had hoses mostly printed out - a few hoses broke off during cleaning.

This is a view of the camera ball. It's a quick and dirty design loosely based on some pictures I found online. The ball doesn't move (didn't feel like going that far down the design path):

(https://i.imgur.com/WGPqFL0.jpeg)

These antenna mounts printed well. The bases are very thin:

(https://i.imgur.com/TDptzwO.jpeg)

Thes printed less well. The shape made it difficult to place supports and I forgot to properly support the antenna end, so they mostly failed, but it's easy to drill out a new one:

(https://i.imgur.com/cKOqX5H.jpeg)

Some of the medium size extinguishers:

Large ones without mounts and the small ones. I'll trim off the excess supports at the bottom as needed:

No need to buy kits anymore, just print them out at home! That pretty much what Industria Mechanika does any more. You pay for the file and print it yourself.

In theory.

In reality, designing the model, getting it into a printable form, optimizing the printing and iterating the process until you get the best results can take a long time.

Some minor work in the "office" - I think it's almost ready to close up:

The radio is a recent print of all the radio parts combined. I added a small monitor on the driver's side to cover the otherwise blank space and I relocated the 24" monitor to the top of the dash. It can still sing out and face either side.

Still need to add a few PE bits, the cup holders, water bottles and piss containers, add a gun rack, fire extinguishers and emergency supplies box to the back wall.

Thanks, Guy.
Almost ready to close up the cabin.

Added an AC unit to the roof, which is the cut down original vent that intruded into the cabin, with some extra bits. The back wall is pretty bare, except for the emergency kit.
The main cabin has two fire extinguishers, cup holders and two gun racks and two AK rifles (without their stock):

Needs a few can’t wrappers and a McDonalds bag.
Seriously, awesome job. Lots of details I wouldn’t have even thought of.

I love the gun racks

Post by: Frank3k on September 08, 2024, 12:36:21 AM
The "gun racks" are just PE strips that I bent into a U until they clamped the guns. I trimmed them to length, glued them to L shaped plastic holders made out of strip styrene and attached them to the back wall.

I'm getting close to the finish line - maybe by the end of the month. All the parts below except the front cab are loose.

 I painted everything above the chassis (painted in NATO green) in Russian 4B0, since - unlike Olive Drab - everyone agrees on the exact shade ("roughly green, depending on how much vodka you drank when mixing it up and how long it's been sitting in the Sun"). I also added Ukrainian digital camo decals to the side of the shelter.

I needed a place for the sensors and anti-drone antennas, so I made a mast of sorts from a Plastruct "O" Scale ladder and cage that I've had in my stash for years. Of course, such a tall structure needs protection from errant cables, so I added a cable cutter as well:

(https://i.imgur.com/f4LrLbT.jpeg)

I made the solar panels in my CAD program, by pasting a picture of a standard 60 cell residential panel and scaling it down to 1/35. I printed them on photo paper with my laser printer and glued the results to some ABS panels I'd printed earlier. I think they look pretty good, even though the edges of the ABS still need trimming. The four panels would generate roughly 1200W on a good day. Enough for the electronics on the vehicle, or a very slow charge for the vehicle's main battery.

Here's a closeup of the solar panels (and cat hairs, which I'll remove later):

The 20kW generator is at the end of the vehicle, on and extension platform I made.

The location of the two spare s up front is also approximate. That platform still needs work.

I think I'm done!

Not too dirty; just some road dust and mud. I scratch-built the walls between the cabin and truck box/office; they would flip down as needed. The cable cutter at the nose looks a bit too complicated, but maybe it contains instruments to detect mines or something. There's a 3D printed winch (that I made for a Land Rover build) over the cab. I made a rough mask for the Ukrainian cross ID and painted it on with an AK pen (I'm not getting a kickback from them. I wish...)

I printed the sensor ball, but the drone detect/disable EW array is from the Magic Factory MRZR kit:

Other side with our French mechanic for scale. I left the large Diesel tank, since the generator will need fuel. The Ukrainian flag is just Tamiya tape painted with (...again....) AK pens:

(https://i.imgur.com/Ro5N5aE.jpeg)

The solar panels would generate about 1000W - 1200W on a sunny day.

20KWh Generator and fuel pump. The generator, fire extinguisher and antenna mount are 3D printed. I also have a small printed video camera in the upper right. The antenna is from some thin plastic wire that Jeff sent me.

Party time! The sensor ball has some Tamiya Interference tape on the lenses and so does the self driving/3D terrain scanner in front of the cab. This was inspired by all the Waymo driverless Taxis in my neighborhood; I see at least one a day (they also used my 'hood to train the cars):

I also started on an interior, but it exceeded my motivation budget. The doors to the truck box are only glued in place with acrylic glue, so I can open them at any time. There's a bathroom, some equipment lockers, a table and bunk beds:

This has been a long, but enjoyable project. It's also very, very heavy.

Wow! That is dead impressive, Frank!  :smiley: :smiley:

And a pretty decent deck to party on ... although those spare tires are kind of taking up prime BBQ real estate  :icon_surprised:

Moi aussi!  I definitely new new specs ... but, to be fair, it took me ages to realize that when Frank said "Ukrainian flag" he really meant "Ukrainian flag"  :))
