Shapeways is a big company and has certainly more powerful 3D printers that my makers, here, have not. I know now what they are able to do and what price they apply; Shapeways makes a very good work but expensive. And more, when I can find spare parts on the ATLAS website, I don't hesitate one second; cost is negligible! and I have, like everybody, to pay attention to my money!!!!

But thank you RDUN for your interesting comment. It's very useful and kind.

Have a good sunny sunday like here!

Before continuing to build the SD40, something I wanted to do since a while: update the motors housings.

The first I made were very simplistic but operational: motor housing on the left and middle dummy housing on the right (flat top because the bolster is just above.

motor block and dummy

I thought it was better to re-do these parts and update them to look like (almost!) the real one, always thinking that I had to fit them to my model, even if these parts are not completely visible.

I found a few photos on the net and here is the result of my work; the dimensions are always the same but I changed the shape and added some details:

10_01_1306 ensemble essieu moteur vue arrière

Without wheels and gears:

10_03_1234 carter moteur   10_03_1234 carter moteur_b   10_03_1234 carter moteur_c

An exploded view to show you the differents parts:

The dummy housing has had the same updates but the top is always cut!

All these parts are now ready to be printed, for exemple this one:

10_01_1311 flasques 1 et 2_grappe de 4

I notice now on the drawing above that it lacks a 1mm hole at the bottom of the left part!!!!!!!!!!!!!!!!! it means that I have updated the drawings but not the . stl print file!!!!!!! we should have four eyes!!!

That's all for this evening!

Many thanks BH! I never modeled in S scale, sorry!

On this forum? Perhaps a friend of mine; his pseudo is "Jamo" or "SJVRR".........

Work of the day:

Temporary assembly of the long hood to check out if I find something wrong:

First, insert of the screws in to the chassis from underneath:

17_7_2018a

Right side:

17_7_2018b

Left side:

17_7_2018c

Some views in adding the roof and the back end:

17_7_2018d

17_7_2018e

17_7_2018f

It lacks the motor side access on the left side and the rear air grilles: these parts are not in accordance with what I want; so my "3D guy" is doing them again. 

I asked prices for the door latches and other parts but no answer.................

As long as I don't have them, I can't give the long hood the first coat of primer!

I'm also waiting for the front short hood; I gave it to be done by another 3D maker; hope this time it will be all right!

A bientôt

A loooong break all summer long for working on this engine! forced break too because my main computer has broken; I just bought a new one last week. I have another older one which helped me but all the files were on the broken one! So I kept on making 3D drawings for other projects and they kept me very busy!

So I take again my tools out of the drawers and began to work!

What I wanted to finish: the rear long hood.

First all the parts were painted with a grey primer and nuts installed to fix the shell on the chassis:

25_10_2018a 25_10_2018d

Aftern came the assembly of the long hood; it's a shame that I had not an actopus near me to hold all together while I was setting the glue! ...but everything went well, doing slowly and quietly!!

Now, I am going to send to my 3D maker the stl files for the dynamic brake housing and all the parts for the cab.

So, see you soon

I finally received from SHAPEWAYS the first parts of the cab after many mistakes of delivery by UPS!!!!!!!!!! hoppefully, nothing broken!

The quality is top level, very fine making and dimensionning.

The two parts on the left are made in a resint that allows printing of details from 0,2 mm (hollow or in relief), the part on the right is made in another resine, more "ordinary" because less visible (it's the floor of the cab).

It remains now to clean them, add some more details on the two walls (door latches, grab iron, nuts for fitting with the chassis, etc...) and paint with primer.

Latches and ends of hand rails installed on the two sides:

24_11_2018

The holes for the end handrails (0,6 mm dia) are made during the printing.

On the right part, the whitish traces that you can see around the window, above and under the latches are inside the material, not on the surface.

You can notice the fineness of the details rendering; it's amazing! I didn't think that my drawings would be so well respected!

Great work mate.

I sympathise with you on waiting for parts.

I ordered some  loco wheel sets my mistake should have double checked the number I wrote, wrong one's arrived had to send them back yesterday now don't know when I will get the correct one's It's hard when your overseas.

Keep up the good work! and have a Happy Christmas from West Australia !  Roo
