The rest of the details for my HO scale model Small Engine shop

There were a few items that I did not get printed in the first go around for the small engine repair shop. I added them to my last order.

I used an N scale tractor and some printed parts I designed to make an HO scale riding lawn mower.  Here we have a seat and steering wheel shown with the partially disassembled tractor.

In a previous post I showed the single blade model, so here is the double blade model with the belt drive.  I am missing the steering wheel on this one, so I guess it is in the shop for repairs.

Here is another riding mower I based on some online pictures of 1949 era Fairbanks Morse riding mower.

The bench grinder I ordered with my original group of designs was too small, I sized it wrong, so I resized it, and ordered it along with some more chain saws, a air compressor, a large engine to set out back as junk, and another rider. 

I will have several chain saw motors, both as junk out back, and setting on benches in the shop.  They are one of my favorite details.

The Winchell riding mower was manufactured in Fort Scott Kansas, so in the late 1940's, so I thought it would be a perfect fit for my model railroad.  Here is my model based on some pictures I found online. 
Two more post planed on 3D printed items from shapeways, then I will start on some items that I designed and printed on an Afinia H series printer to which I am a part owner.  There are a few pictures of items I have printed at http://model-railroad-hobbyist.com/node/11204.

I need to write HO scale and Model Railroading more often in my blog

All the adds on my blog are for building, nothing model railroad or 3d printing related.  This time I am going to cover the details I designed a printed at shapeways.com for a small engine repair shop.  
Here is an overview of several of the items I designed and printed for detailing my Lipasek's Small Engine repair model in HO scale.

The green tractor is an N scale model manufactured by Athearn, but I added an HO printed seat, steering wheel and mower deck.  There are more pictures of that particular model in an earlier post.  

Small engines includes chain saw, so I ordered some from the local hobby shop.  They have now been on backorder for several month.  Good thing I did not wait, and went ahead and designed my own to be printed at shapeways.com.  

I could not find commercially available models of 1940's era riding lawn mowers, so I designed mine based on photos available online.  If you search 1949 lawn mowers, there are several to choose from.  The drill press is generic, and the bench grinder I printed to the wrong scale so I have reordered it.

Both benches were printed, including the details under and on the benches.  If I had to do it over, I would not bother printing the square bench, as I could have built it from styrene or wood, and the boxes underneath would have been much easier to paint as individual pieces.  I also have a air compressor that should arrive today on UPS, a day late due to the snow storms in NY.  That and the grinder should complete the details from shapeways.  

This is one of my all time favorite pieces.  I have shown it to several people, and it is so fine, people are scared to touch it, for fear of breaking it.  Products printed this small in shapeways Frosted Ultra Detail material or very brittle.  The bell for the church has been repaired three times, and it is still not installed in the bell tower yet.  I am going to redesign it before I make it available on shapeways, http://www.shapeways.com/shops/nvrr49.

More 3d printing and model railroading to be posted next week...after the grand baby's shower this weekend.

Blairline Church

In this blog, I am only going to cover the 3d printed parts used in the construction of the Blairline church in HO scale.  If you would like to see more on the construction of the church, I am doing a build thread on kitforums.com.  Here is the direct link to it, http://kitforums.com/viewtopic.php?f=6&t=7876

I have always wanted to build a church and super detail it.  I chose the Blairline church, as I had never built a laser cut wood kit.  I started designing the interior furnishings by looking a different church furniture supplier web sites. I also decided, after getting the kit, that I would add roof beams and a bell.   

Here is the drawing of all the parts.  I sent the drawings to shapeways for printing.  I printed the beams in FD, Frosted Detail, and all the other details in FUD, Frosted Ultra Detail.  I hollowed out as much material as I could of the beams to save material, i.e. money. 

This overview of the furnishings shows the bell was so weak after printing, that it broke in shipping.  I reinforced the bell frame with some styrene.  In this picture you can see the inside of the rear door in the center bottom of the photo. There is also an interior front door that I printed.

Here is the front roof support being glued in place, and also you can see the interior front door. 

 After I assembled the bell, since it arrived broken, I set it aside, in its place.  It looked so good, I took a picture.
I still have a couple more installments on shapeway, maybe three, as I have another shipment coming from them this week.  Then I will be blogging about then Afinia printer that I own part of.

Details on the other side and the roof

This post will cover the 3d printed details on the roof and the other side of the building.

Here is a view of the other side of the building and a good view of the roof.  On many model railroads, the roof is the one side of the building that is the most visible, yet so many ignore the detail possibilities.  This particular building kit came with the chimneys, and detailed roof material.  I  added an access hatch and roof drains (note the corresponding drain tubes made from brass tube at the base of the building). 
These vents were printed a shapeways, and are 3/16" diameter at the base.

 This kit, due to it's design, had several seems that would look better if slightly hidden.  The pipe on this side, and the electrical service on the other were placed to distract the eye from those kit flaws.  The pipes I designed are hollow, real pipes, and can be assembled in just about any configuration.  These were printed
in the FUD (Frosted Ultra Detail) material, and are quite brittle.  Bending them or putting them under any stress will cause them to fracture, but with care, the go together rather easy.  Next time I will cover a few other details for HO scale structures walls and roofs.  In future posts I will be covering some lumberyard details and a small engine repair shop.  Both, detailed with items I designed and had printed at shapeways.  There will also be a few items in the upcoming posts that were printed on an Afinia H series printer.
