I've already made a review where I made a key ring bottle opener. This time I've decided to make a classic style bottle opener. As usual I will make this bottle opener using lost-foam casting technology.
Step 1: Cutting a Bottle Opener
First of all, I need to cut out a shape of a bottle opener from a polystyrene sheet.
Step 2: Making a Mold
Using green sand I'll make a mold. I always use 2 risers. In my opinion, it's the easiest way for casting.
Step 3: Casting
Before casting I load as much aluminum as possible into the crucible. When aluminum was melted I added more. On the final stage I threw away the dross. After that it was time to cast
Step 4: Opening a Mold
After casting I waited for 15 minutes and opened a mold. Casting result is not bad :)
Step 5: Cheers!
When a bottle opener is ready it can be used for opening an appropriate bottle :)
