Great tutorial on solid pattern casting! I've had a bit of trouble with projects like these. But this video will help considerably... very educational! THANKS!
I'm at 13:00 in and wonder.... Why do you completely fill the design completely in the drag as opposed to filling the drag say 80%, submerging the design and then filling the cope? In other videos I notice where people do a half and half design (even with a solid object), and with a packed enough drag and cope are able to make perfect pieces. Just curious if you've found any advantages on doing it this way.
Hi Shawn, I am filling the drag part of the flask as Its very important to have all the sand rammed in thoroughly, If the sand is not rammed properly you will have a bad finishing after pouring the aluminum. This is the down side of using a solid pattern, its time consuming to make the sand mould. The ideal is to use a split pattern like the one I made in my video: Aluminum casting of a boat cleat ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-G1Re8gdSPDU.html
I Thank you a lot for your tutorial but i can't catch your pronunciation so that i can't spell what powder you are using, can you please spell what kind of powder you are using to separate the two parts of sand casting? & thank you again.
Hi Tesfaye thank you for your comment, the parting powder that am using Is a simple baby powder, however you cam get commercial grade as well (Calcium Carbonate). I made quick research for you: "Parting Powder prevents all types of moulding sand that is packed around the pattern to be removed easily from the sand without sticking of sand to the pattern or adjoining sand. Recommended application The parting powder is sprinkled from a finely woven dusting bag over and around the pattern onto any surface that easy separation is required from. Be careful not to use too much in corners and on fine patterns as detail can be lost".
