While I rarely make molds of stuff, I just want you to know how much I like your old timey equipment..archbar and Fox trucks, truss rods, and HANDLAID track! Modelers of "turn of the century" and earlier are rare as hen's teeth and should be appreciated. Show us some more photos of the layout.

Wow! its been almost a year since this topic

has seen any activity, it would have been longer

but I was clearing space in the hobby room and

I found my little stock car hiding under all kinds of

plans and unfinnished stuf. Looking it over and

you will see in the pics that this first attempt

at casting was a success in at least learning

what not to do and what should have been done.

Don't get me wrong, the mold is something I

can work with and build credible cars, but I

am thinking about building another master

and trying again. Time will tell.

So here are the pictures with the side boards

painted and placed.











I am now attempting to cast trucks for this car,

as I type the resin is curing in a mold and it

needs time to harden. Pictures tonite!

Carl,

Pasco, Wa.

I have found that putting the castings under a floodlamp warms them up slightly and really helps then sections cure quickly and completely. You don't need them hot, just warm.

Seems like an inexpensive way to de-air a casting, but it does not specify how much of a vacuum it creates, too little, and the bubbles won't burst, they'll just get larger.


I used a Food Saver http://www.amazon.com/FoodSaver-Advanced-Design-Vacuum-Packaging-System/dp/B000AAYD6W/ref=sr_1_4?s=home-garden&ie=UTF8&qid=1338299867&sr=1-4  because we own one and use it to seal canning jars, food bags, etc. and it has separate containers that can also be sealed.
I am new to this and just used it to de-air the RTV and the resin (before pouring).   Worked fine.   I may try it on the actual casting after my new masters get here from Shapeways.
:cool:

Going to make a string of stock cars by casting
resin into molds I made many moons ago.
