The Great LSM Twins Group Build ends July 3, 2024 √ó

OH! OH! yupp I did it, I'm starting another build project

Recommended Posts

Hey guys 

¬†Yeah I know another one...it's¬† a disease...please I need help...lolūüėĀ;):omg:

 Ok now that thats over. I'm starting a build thread on a 1/16 scale Monogram Kenworth W900 Conventional kit. I plan on doing it as a tri-axle heavy haul, with custom made headache rack, custom made air lift axle,  decals from Jerry at modeltruckin.com.

  I'm using the kit Caterpillar 3408 V8 engine, but I'm fully plumbing it with custom Cat oil and fuel filter decals. It's going to have aftermarket 385/65R 24.5 front floats, 385/55R 22.5 super singles for the lift axle and 12.00R 24.5 drive tires. I'm using the kit wheels, but I had to customize them to fit the front floats and the super single tires.

  I've  started in on the frame construction. This kit had a flaw when I got it, the passenger side frame rail was a short shot :wallbash:. I was devastated because these kits are scarce as hens teeth, or OH MY GOD! expensive on Ebay. So, I found a guy on YouTube that was making a custom stretched KW and I asked him if he had any left over parts and viola! He came through, he sent me a bunch of parts both rear frame rail sections, extra cross members and extra air bags. Here are some pictures to look at.


this is the kit I'm using for this build.

It's going to be for their 1/16 RC Freightliner Cascadia (the blue truck in the photo). If this is anywhere near as good as their 1/50 scale diecast one, I'll be using it for the Big KW's trailer, along with a Bruder Cat 336 excavator for the load. Yeah this is going to be HUGE!

Nice progress and the pace at which you work is unbelievable.

Keep 'em comin


Hey Peter 

  Well since I'm retired I  have all day to work on my models. I usually start around 11:00 or 12:00 and work to around 5:00pm. When I was younger and working I only got to work on them on the weekends. My wife still works. She works for FCA (Chrysler) but shes furlowed at home on the computor (Cad designer) so she keeps occupied and out of my hair...lol

Ok here goes, I think I got this right

1) 1/25 AMT Kenworth W925 - using this for the tractor for my Michigan gravel train.

2) 1/25 AMT (2) gravel trailers, front one will be stock length out of the box, rear one will be shortened to 18' length, with custom made dolly for the Michigan gravel train.

3) 1/25 Revell Peterbilt 359 tri-axle heavy haul tractor built from the Revell "can do" wrecker kit. With custom tanks, headache rack, etc.

4) 1/25 AMT Peterbilt 359 "California hauler" made into a dump truck with dump bed from AMT Autocar dump truck kit.

5) 1/25 AMT Caterpillar D8 bulldozer, with custom R.O.P.S., and fully plumbed and wired with custom 3D printed tracks.

6) 1/25 scale custom made from scratch, 3D printed and what ever I could find from the scrape box stuff. XL120 Specialized drop nose lowboy trailer, with 2 axle jeep and 2 axle nitrogen stinger/booster. With tractor it's just barely under 5.0 feet long!

7) custom made from scratch Caterpillar 374 FL excavator with tracks from Bruder to go on the XL120 lowboy trailer.

8) 1/24 6 axle 48' flat bed trailer built from scratch with real wood decking and custom rolled steel loads.

9) 1/24 Italeri Peterbilt 378 tri-axle heavy haul with 36" sleeper, Cat Ci5 twin turbo engine from Moluminum, headache rack and alot of extras.

10) 1/24 Italeri Mack Superliner II built as a Australian road train puller. It's got a Mack E9 V8 with Mack 12spd trans. 6 spoke color matched wheels fully wired and plumbed. I have a 1/24 tri-axle Italeri fuel tanker to go with this, just need two more plus dollys and I got me a road train!

11) 1/24 Italeri Western Star fairly simple build on this one. It will have a series 60 Detroit diesel, I  swapped engines with the one from the Peterbilt.

12) 1/24 AMT Peterbilt 378 being built as a long nose 379 fully wired and plumbed.

13) 1/16 Monogram Peterbilt 359 short hood, with functioning front steering, custom and 3D printed Cummins NTC-400, opening cab and sleeper doors, fully wired and plumbed.

14) 1/16 Monogram Kenworth W900 Conventional being built as a tri-axle heavy haul tractor. This has the kit Caterpillar 3408 V8 engine. It will be fully wired and plumbed, but no functioning steering or doors.                     This will eventually have a 1/16 scale Diecast Masters XL120 lowboy trailer (supposed to be coming around Christmas time) to pull the 1/16 Caterpillar 336 excavator that I have from Bruder, yeah its a kids toy, but I can modify it to look alot more real.

15) 1/24 Italeri Peterbilt 377 (this is the kit that got all this started) left over from 20 plus years ago that I'm going to do as a single axle daycab tractor.

WHEW!!!! :omg: I also have 12 or more 1/32 and 1/24 scale plane kits to finish too!

Lets see I'm 71 years old now so I think I'll probably get done when I'm about 250 years old...lol:DūüėĀ:hsmack:

Hey all 

 Well I have the 36" sleeper done. I cut 2 scale feet out of the kit sleeper to create this.

20210725_160453.jpgThis view shows the 36" sleeper in place on the frame. I have to cut off the rear sleeper mounts from the frame and move them forward to fit the new 36" sleeper.

20210725_160432.jpganother view of the sleeper. You can see the fender rubber lips that I added to the front fenders after grinding the opening bigger to fit the large front floats. Well that's it for now be back soon.
