Boolean21's 1/10 M923 - 5 ton truck - Newbie try to scratch build a truck body... :D

found a photo of the m923 beside a pickup truck....


wanted to do a flip open hood like the actual truck... but too much work...
so did a removable hood instead....


more pics


Maybe should do a civilian one instead of a military truck?

whoa nice leh bro. do la bro! burn more midnight oils.

Not much oil left...

Do the flip open it will go for it be just like the scania. Go for it woohhh! or may be a later modification after its built lol

see how it goes man..

limited mid night oil to burn... and still a few projects in mind...

Placed the M923 cab on the unimog chassis to see and take some physical measurements for the new chassis to "double-confirm" that the drawing dimensions are ok...

have to trim off the fenders shorter... :S
purposely extended the fenders to make sure the crawler wheels are within the fenders... end up extended too much!

on "paper" the left side shows the extension.... seems like my extension too kiasu....


placed on unimog chassis...

nice

Swee swee!!

Lego! I see Lego! Can't show this to Patrick...

Thanks bros..
looking forward to you guys' build threads updates too!

hahahha!!! yeah... i don't have the scale jacks that the guys in rccrawlers and scale 4x4 rc use.... so lego bricks are the next better option!

Marked the cut lines....


Dremel off the fenders.... now left with a last piece of cutting disc....
where to buy the cutting disc ah? can the Hobbyking rotary tool use the cutting disc for dremel?

some photos after the CUT....


Sanded smooth.... now should look better... i hope...
lesson learnt... dont be too kiasu and leave too much allowance... hahahaa...



took some pics with the "driver" of the m923 to compare with the soldier pic... this guy is very tall compared to my other drivers... should have taken a photo with a more average height wrestler...




this is how the cab looks now....

Now looks nice !
I also want to buy cutting dish

Looks garang already.

Thanks bro...

got a little time to spare....
so started to work on the chassis rails....

using 2 strips of 80cm long, 1inch x 1inch, 3mm thick angle bracket...
need to cut out a groove to clear the venom creeper transmission case...

here's some photos.


lazy to set up the power drill, so tried using the IKEA power screw driver to drill the holes.... after 1 hole... seems like the power screw driver was burnt...

opened up the power screw driver to take a look at the motor and gear reduction unit...

metal gears in the GRU, and running a 380 motor... will keep this spoilt driver and maybe use as a GRU for future builds...

Like dat also can? Brilliant leh bro!

oceanic wrote:Like dat also can? Brilliant leh bro!

Saw a build thread using the great reduction unit from power screw driver before.... So steal the idea...

Dismantled my Unimog U300 transmission and axles from the chassis....


Mounted the transmission on the new chassis rails...


A mock up of the ride height and ground clearance...
I'm too greedy..... want to get a high clearance in the centre for more flexibility...
cos this chassis is planned to be used for a few different bodies!

clearance from the bottom of the chassis rails to the ground is around 11.5cm...
seems like i will be cutting away the bottom part of the fenders as they will be the first to get in the way when crawling over obstacles...

a result of my greedy-ness... drive angles will be too steep if the wheels drop to low in holes, etc.... so to prevent this... i will be adding some travel limiters to limit the axle down travel to prevent stressing the transmission and drive shaft due to the steep angle....


A top view of the transmission in the cab... the advantage of big rigs is the great amount of space... still spacious to put some seats and simple interiors...


Now... need to find time to mount the rear links and shocks to complete the roller....
as well as adding a drive shaft extension due to the long long wheelbase... around 40cm or so....

Nice.

Coming together quickly!

Looks like you made it so big that Patrick can ride on the back of the truck

Hahaha! Good idea!

Whoa its hugh! Awesome build!

oceanic wrote:Whoa its hugh! Awesome build!

thanks bro...
newbie at work...

Finally, found some time today to mount up the middle axle and the rear axle... now it's a roller!

extended the drive shaft from the transmission to the middle axle due to the long long wheelbase....

connected up the esc, rx, batts and did a run... then adjusted the middle axle drive shaft extension angle...

that's all for now...
here are some pics...

managed to find some time to work on the 6x6....

made the body posts using 4mm threaded rod and mounted the front of the body.
the cab mount is still incomplete, only mounted the front, the back of the cab will KIV and see how to mount it as i progress along...


Some photos with the cab mounted and the bed...


made the side boxes using styrene... still need to "mount" it up...


took a M4 bolt and will be using it as the spare tyre mount...


mounted the bed to the frame.... short of one long bolt.... need to top up more bolts and nuts soon....


this is the material and size of the bed... got the wood from Daiso... had previously measured and cut the bed out of styrene when i cut the styrene for the cab...

last week when i went looking for goodies at Daiso, saw these wood pieces and bought 2pcs to see what they can be used for... the wood turn out to be exactly the same size as the styrene i cut previously!


1piece used for the bed, the 2nd piece, used for making the left, right and rear sides of the bed...

some photos of the bed sides...


more bed sides photos with the bed...


next up will be going to get some hinges for the bed sides and rear side of the bed....
the front of the bed will be made with styrene...

till the next midnight oil burning session....

Nice work!!

Very nice indeed! Either the tires are too small or this will be heck of a big truck! Will be good use on the trail for carrying broken-down vehicles

The bed looks awesome with the wood.

Whoa its really huge! Looks great!
Boo use lego to build one mah hahaha, we were talking abt it during last sun trail.

Yes, it needs bigger tyres...
Planned to use super swampers or ripsaw, still havent change them...
