Topics I've Started

Twins in different dresses

21 June 2014 - 02:21 AM

I had this idea the moment I bought the Revell USA snap kits, Kenworth W900 and Peterbilt 359. They share the same engines but I knew they would look different after I build them. But that required a little bit of study on my side since I don´t work in the field and never had a chance to explore these engines by myself. Here I want to thank all the guys who answered my questions in the Truck Stop section of the forum. With their help I was able to build two versions of Caterpillar 3406 engines.




This yellow engine is pretty much the box version with only a slight modifications and a few details added. I followed the article in CM magazine by Ken Smith...


Can´t be thankfull enough to this guy. He lead my hand on a number of projects already.




This white engine is also a CAT 3406 but it´s changed a bit to represent the aftercooled B version. Some parts are modified and some are scratch-built. Like the aftercooler and lines, dip stick and valve cover breather tube. I also changed belts using a rubber line bought in craft store.


Here is a couple of pics showing both engines. Note the differencies between them. The shape and location of the fuel pump, the aftercooler, the plumbing and timing governer cover in particular.
















More to come...




CAT 3406 question

05 May 2014 - 02:50 AM

Can somebody tell me what version of CAT 3406 engine is in the Revell USA snap kits? I would say 3406 A but I´m not sure. Some say that A´s started life as PCTA and then changed to DITA. The others say that PCTA was just the plain 3406 and they were marked A only after DITA came out. Not that it matter to me that much but I wonder what visible changes should I make to the engine to make it a B. Probably a different shape and location of the fuel pump, the conus cover in front, maybe a different shape of the aftercooler... by the way, why there are different shapes of aftercoolers anyway? And what about the turbo side of the engine? Is it the same for A and B or are there any differencies too? There are heaps of pictures on the net but I´m kinda confused. Need some educadion on that. Can somebody shed some light in it for me, please?

Thanks, Jarda  

Peterbilt 351 with Peerless trailer

11 October 2013 - 08:53 AM

I never thought I would build something as old as this - a logging truck of 1950´s. But I watched the birth of brand-new cab for Peterbilt 281/351 and was so impressed that I couldn´t resist. I bought two transkits straight from the author. I started working on one and I would like to have this



or that



As I do not know much about logging trucks of that era I will appreciate every information, every advice, every help that I can get from you. If you see me going wrong direction, please, don´t hesitate to tell me so and get me back on the right track.


This is the first big rig that I started out with frame and not the engine. It is also my first attempt to work with resin material at such an extent. But first, the good old styrene. I said I started with frame but that´s not quite correct. Actually, I started with the front axle. I didn´t have any spare one and so I copied the RoG Peterbilt 359 axle using styrene sheets and channels. Believe it or not but the axle alone, without springs, consists of some 30 parts.






The brake chambers are part of the cast set. The rest is scratch built. So is the frame. The rails are doubled for better toughness. The cross members is a mixture of resin cast, the original RoG parts and scratch built ones.










The rear suspension is attached just temporarily. I will rebuild it if I don´t get better one somehow. I hope this kind of suspension is okay for logging truck. What do you think?




I added some bolts cut from Plastruct hexagonal rod. The job is not finished yet but I think I will put them only on the outside.




Next time I will show you the birth of the cab using the author´s photos. And the modification that I have done to it. Till then I would like to know if a non turbo engine is okay for logging truck of 1950´s and if I can use two gear boxes for a twin- stick shifting. I would really appreciate this information.

Transmission for twin stick shifting

07 October 2013 - 11:33 AM

If I want to build a model truck with two shifting levers in the cab, what transmission do I need? Are two separate gear boxes in the frame or are they joined together in one block?

I´m talking about 1950´s Peterbilt. Can somebody tell me what transmission I should look for? A picture would help a lot.


Thanks in advance.


Peterbilt 379 with D.T.U.

30 September 2013 - 06:13 AM

With the sun in the sky on Sunday I took the outdoor pictures of my finished Peterbilt 379-119 Long Hauler with detachable towing unit. Those of you who watched the progress in "On the Workbench" know that the model underwent some modifications, like stretching the frame, reshaping the hood, changing the front springs, rearranging the firewall, adding the ultra roof, and some other things. 

Not only have I changed the truck but I also scratch-built the detachable towing unit (D.T.U.) and the headache rack. The unit is inspired by Holmes Miller unit. But with no dimensions available I can´t guarantee the dimensional and proportional accuracy. The unit is fully operable with the excetpion of the winch. The front supports can be extended and dropped. The desired position can be fixed with the pins, just like the real deal.
