Looking for Atlas rs1 install pics

(1/3) > >>

Mark Wengert:
I am looking for pictures from anyone who has installed a sound decoder in an Atlas classic rs1.  I want to convert from dc to railpro but i run a lot of rs1 and s2 locomotives and there doesn't seem to be enough room to install any of it.  I want to use railpro but if i cant get it to fit i may have to go digitrax dcc for a full board swap.  Thanks for the help.

I have an Atlas RS1 waiting for an install but haven't lifted the shell yet. I have done an Atlas S2 (old tooling). Sorry, no pics. I'll take pics on the next one. I have 5 more S-2s waiting.

The LM had to be removed from its plastic shell to fit inside the hood. Mounted just forward of the cab at the top of the hood. Two small styrene strips glued to the shell sides act as a ledge for the LM to rest on. Kapton tape protects the bottom of the bare LM. The rear flywheel diameter had to be machined down .065"  to clear the underside of the LM. Wiring harness extends into the cab. Extraordinarily tight installation. I can't imagine trying to do sound as well.

Mark Wengert:
Well, thanks for the ideas and info.  I think the product is great just not sure if it is in my skill level and tooling to get these installs done.  If ihave to mill the flywheel down, i dont know where i would get that done around here.   I am not giving up yet on rail pro.  Maybe some others will chime in with ideas and pictures to help out.  Thanks again.

Alan:
Poor man's milling:

Remove the motor. Tightly wrap the motor frame with a wash cloth. Clamp in vise. Cut a slit halfway across a piece of shirt cardboard. Slide the cardboard between the motor frame and flywheel to prevent filings from entering motor. Apply power to the motor. Hold fine file against rotating flywheel. Blow away any loose filings.

William Brillinger:
And don't be shy about telling Ring Engineering you want to see a smaller LM!
