          Great Caesar ghost ... you finished...looks great.. when you started I bet that wheel set had no rust...

      This should look great on the pike!

      Great Job !

       

      Thanks Sean.....the rust is real in this scale! No weathering needed :) I will set the wheels in the lathe and sand the rust off with carborundum cloth.

      99% Skill methinks! Great job.

      I'm voting for the  bridge with a bribe: you'll deliver umbrella drinks to your lovely on the pool float.

      Turned out great Gary!   You’ll get an overwhelming sense of satisfaction every time you look at it, knowing you did the job yourself.   I also have to vote yes on the bridge over the pool! Just tell the CEO it’s our fault, that we all demanded it.

      i think you will be able to get the spring action you want, you’ll just have to pick the right springs with the proper heft to do the job.  If I was going to leave my switch where it was at I’d be doing the same thing to it.   I’ll se we’re it ends up in the new plan be fore I go and do that thought.  I look forward to the switch stand updates!

       

       

      Randy, you guys don't hold much sway with the "CEO", after reading these comments, she said flat out......NO :)! After almost 49 years, I saw THAT coming! :)

      I looked up the spring number on the plans we got for the turnout and found the compression spring number they use. Century Spring right here in Los Angeles has them. Problem is that it is a minimum order of $40 and these springs don't come close to that. If you look in your Bill of Materials at the start of the instructions, the spring IS noted.

      I did lift the entire switch from the assembly table and onto one of my locomotive racks (an 8 footer) and it was a lot lighter than what I figured or imagined. And surprisingly sturdy.

      During the build of this turnout, I used MasterCam to try various designs for the switch stand and the throw bar mechanism. These drawings show the final design I will use.

       

       

      The doub;le compression springs to compensate for over-travel and hopefully function as a spring switch :).

       

       

       

      I added the drawings of one of my Baldwin P.E. electrics and my 72 inch steel gondola (to check clearances on the switch stand and how the 6 foot car would look on the 32 ft. radius on the turnout.

       

      Now out to the shop to start machining parts for the mechanism. :)
