Picture 1 :
Here are tools to work during the foundry process.
Prepare your tools.
Picture 2 : Put half-pattern into the frame (we first use the bottom part of the model)
Add some talcum powder onto the pattern.
Picture 3 : Sieve the sand upon the pattern to get a better quality of sand just around the pattern.Finish filling the frame with normal sand.
Picture 4 : Press the sand with your hands in order to get a more compact block of sand.
Picture 5 : Add some more sand over the first layer.
Picture 6 : Add some more pressure with the help of a pneumatic hammer.
Picture 7 : Use a shovel to take the extra-part of sand away.
Picture 8 : Turn the frame over.
Picture 9 : Pour some talcum powder upon the whole. Hmmmmm !
Picture 10 : Put the second half of your pattern (as well as frame) onto the first half.
Picture 11 : Position the vent on the pattern to let the air away and let the metal come instead of it.
Also place the downsprue in the sand : it will allow the metal to flow in when casting.
Picture 12 : Repeat the operation from step 3 to step 7 to prepare the second frame.
