Just to keep things clear, you referred to a 'latex mold' but the bottles shown are Room Temperature Vulcanizing silicone rubber.

You are correct - some of the first materials I used for mold making were called "latex" so the name has stuck with me. I have been buying my mold making materials from Micro Mark lately - I have tried three different silicone rubber types with similar results. They are classified by mold strength and curing time.

Thanks for the kind words and for stopping by the thread. Great to see you on the forum.

I returned from my fishing tip all ready to work on the layout.  I had lots of time to come up with new ideas for the layout because the fish didn't bother me.  Wayne Olson was also along on the trip so we got some quality Model Railroad BSing done between casts. We also solved all of the worlds problems if only we were in charge.

John,  Model BSing is the best kind of problem solving. Obvoiusly, the bureaucrats in the nations capital don't do it. Oh wait, they do in front of the cameras.

So Tom..........

So are you saying that model related BSing is productive and congressional BSing is not............

Unbelievably insightful.

Thanx

ELECT a Ledbetter to Congress -
They'll teach'um proper BS'in'!!!

Dave..............


A Ledbetter in congress............... that absolutely staggers the imagination.

BSing would rise to a completely new level...........

This would surely be marked as a high tide marking on every bridge abutment in the country.

COOL  ! ! ! ! !

I agree that the BSing is a great way of solving problems on the railroad. The problem is when you start paying someone to do the BSing - that's when it all breaks down and you get what we have in Washington. They even think they have the power to change the definition of words. Take progress for example. Okay enough of that - back to the railroad.

So it's time to get back to building the layout after our BSing.  I made a mold to capture the detail on both sides of the concrete wall castings from Brambell's - because of the site layout I will need to extend the wall so I'm making some extra castings.  Here is a picture of the mold box.

This a picture after the pour - I made the mistake of not gluing the metal castings to the foam board before pouring the rubber and one of the castings fell over during the pour. No real harm done - I will just have one casting with one sided detail and the rest with two sided detail. Here is a picture of the mold box after the pour.

Here is the rubber mold after the metal castings have been pulled and the flashing cleaned up.
