Thanks for the building thread. Looking forward to learning. The casting information alone is invaluable.

Tonight, as promised, I'm trying to update this thread with the pictures and explanation of the casting process.  I'm dealing with a very slow internet, so we will see how far I get before I wait for better service.

Here is a picture of the last card of castings as they come out of the box.  Bob does a great job of packaging them.  I cut them out of the bubble wrap and place them directly into the mold box.

The material I use for my mold boxes is foam artist board.  This looks like gator board but it's a much cheaper version - in every way.  I get it for less than a dollar a sheet at the craft store.

The castings for Delabarre's are now on the bench in this picture - I will be making mold boxes and molds for all of these castings in one batch.

One of the best tools that I have found for cutting the artist foam board is this little knife that allows me to cut nice even strips for the side walls.  I bought this at Micro Mart.

Don't put it in your drawer or on your workbench without the blade guard - not included.  It gives you a great reason to drink a bottle of your favorite wine.




It uses a #11 exacto blade.

Here is a picture of the slitting tool in action.  It works great - I'm very happy with it.

For a mold like this - that I'm only going to make a few castings from - I make the walls of the mold about 1/16 of an inch higher than the casting.

Now that we have our strips for the sides - it's time to get out the hot glue gun.  But first, get out the gloves. Credit to Frank Baker for this tip.  Cotton gloves work great - when your working with a hot glue gun - to keep you from getting burned.  I keep mine on top of the glue gun in the drawer so I don't forget them. This is one of the few jobs I still use a hot glue gun for but it does work great with the artist foam board.

I split the casting up into three groups, three different mold boxes. I try to arrange them so I use as little mold material as possible.

I have all the pictures ready to post to complete the castings but it will be a couple of days until I can post them. I need to wait for a new modem that is compatible with an an upgrade to my internet service. It took 15 minutes a picture to upload them last night. I will keep taking pictures and building while we wait. Please stay tuned.
