ah...now you are into 'verification of position' on a machine, which is a whole science in itself -> not the least of which is room temperature control.
as CTM asks -> is this a hand cranker, stepper or servo machine?

Re: turbulator on vert boiler worth it?
Half as**d or not, it will help. Some of the original industrial turbolaters were on gas fired vertical boilers, or water heaters. Absolutely no reason they shouldn't work.. The other option is a lot of small tubes in the vertical, which from a heat transfer perspective amounts to the same thing but...

Re: 3/4" scale Juliet 2
don't remember anything about the springs...sorry...that was before breakfast .....40+ years ago. I am pretty sure we went with the standard, and when they sagged, stuck in the rubber bits and ran it that way for 20 years....it is just sitting now because of a boiler problem related to threading scr...

Re: 3/4" scale Juliet 2
Many of us whom have been there done that with Tich and Juliet models have benefitted from added weight between the frames in the form of blocks of lead. I seem to remember adding 4# of lead. Does not sound like much, but on a 25# loco. While you are making springs, a few that are 10-15% stiffer tha...
