Does all this add up to a group of S gaugers where some are hinged and others
are unhinged??

Subject: RE: Re: {S-Scale List} Hinged or solid points to throwbar
I soldered all my points to the throw bar and all the points were hinged for
both code 100 and code 125 rail. I made the hinges for 125 rail out of SHS
insulated joiners and for 100 rail out of PECO insulated joiners. The throw
bars were made of PC board with a gap in the copper foil. The rail soldered
like a charm to the foil. The main trick is to heat the end of the point so
that it would melt solder before making contact with the foil. The foil
delaminates if it gets too hot. Only failures were initial bad solder joints.
They held for 10 years or more. One aspect I didn't like was that some of the
point assemblies would work their way away from the hinge until the throw ran
into its adjacent tie. There was not enough movement to cause the rail to work
free of the hinge joiner; I just didn't like the unsightly gap. I think this
creep was due to the tension at the rigid joints at the throw bars.

Michael,
I have elected to go with soldering the rails to the throw bar, but I
don't have years of "in use" experience. Therefore I would also like to hear
from anyone who has had such in place for some time.

Time for a final (?) decision. Should I solder the point rails to the
throwbar, or solder a tab to the rails and put a screw through the tab into the
throwbar? I'm most curious to hear from people that solder the rails to the
throwbar. Fill in the blanks: In ____ years of operating them I've had _____
solder joints come apart.
