48' MAC Trailer, Kenworth T800, Peterbilt 379 Tractor, and More

I continue to find bits of time to design more N scale models for printing, and attempt to keep up with the actual painting and finishing of the models that I have ordered.  I have resisted the creation of mudflaps and DOT stripes for a few of my models, but know that step is inevitable, and I will bite that bullet soon.  Meanwhile, my MAC 48' trailers are in fresh paint, and thought I would share a couple recent photos.  These are now available on Shapeways.

I just recently completed a Kenworth T800 truck body design, and submitted my first order just a couple days ago.   This model will be very similar to my first Pete 379, and will fit my 22' aluminum grain box.  That said, I also ordered a new revised Pete 379 tractor that I finished recently, which is still a day cab, but with a 5th wheel for trailers.  My Kenworth T800 will soon have a tractor version as well.

I have opened up a couple of my models for ordering for those interested.  Please check them out.

3D Printing - New Model: Tarped Grain Trailer

I just received a new package from Shapeways today.  I ordered a second pair of bottom dump trailers, and a new model, which is a tarped version of my 43' Wilson grain trailer.  It is soaking in Bestine now, and I can give you a better picture of the raw model after tomorrow.  For now, here is the model right out of the little blue plastic bag.  I eliminated some of the interior slopes from the open top version, and added a hole in each hopper to allow the supportive wax to escape, and also reduce the overall material used in making this model.  I am making these available on Shapeways now, since I have a physical model to validate my design.  I will post more photos on Shapeways of the finished model once I get that far.

Trains or Trucks? I Forget

I feel like all of my attention lately has been focused on N scale trucks, which is great, but I need to remind myself that this is a model railroad hobby, not a model truck hobby.  Although we need trucks to support our N scale empires.

I find myself making small incremental progress, and hope to get several models under my belt, build a small fleet of trucks, and then turn my attention back to my new layout project.  Of course I plan to keep allocating time to designing new truck models and anything else that I may need where 3d printing can fill a gap.

So far, I am very pleased with my experiences with 3d printing and Shapeways.  For those of you that have purchased my models so far, please don't hesitate to drop me a note and ask questions or share your finished models.  This whole experience is new to me, so I certainly don't have all the answers, and look forward to gaining some best practices from others as well.

The Trail King bottom dump trailer is almost finished.  I need to apply DOT stripes to each side and add mudflaps.  I will try to share my DOT stripe technique in a future post, however, in a nutshell: I use MS Excel to create a grid or line of red/white/red/white dashes, print them on regular paper, use a hobby knife to cut a very fine strip of paper, spray the backside with adhesive, and stick it to the model.  That is how I did the grain trailer.  On that model, don't forget to add yellow marker lights, 5 on each side.

Here I have the Trail King on an R model Mack which actually doesn't have a 5th wheel, but is a suitable model for a construction rig.  It looks a bit small on this trailer however, so it will likely need a Peterbilt or Kenworth tractor.  This model is available on Shapeways now:  http://www.shapeways.com/shops/NScaleAddict


The 379 Pete grain truck is nearly finished.  For those of you who purchased my grain boxes, the small nob on the side of the box is intended to hold the tarp handle which you can make out of a piece of brass wire.  The handles typically hook across the back of the box, or in this case on the side.  I chose to do tall straight pipes on this model, although shorter pipes are also common.  Why have the extra pipe extending up there if it is not needed?  I have seen low bridges, load out augers, and other things get hung up on tall pipes.  I personally like straight pipes, and made these out of brass rod.   

Now that I have a solid base truck, I plan to utilize this model for many different configurations.  Stay tuned on more designs.  The options are endless.



Here is a trio of nearly completed models.  Again, not as much progress as I would have hoped, but I feel like I have proven the original concept, and have a solid design to begin building my fleet.

Almost There... 379 Pete Progress

A few minutes here and there, and this is where I am at with my 379 Pete project.  My other time has been spent designing new models.  I just recently completed an MAC 48' all aluminum flatbed.  I have a pair on order now.  


This model will also make a nice day cab tractor, which will require a slight design modification to the frame, and the addition of a 5th wheel.



Here is the 3d rendering on Shapeways of my MAC 48' flatbed trailer:
