Well, I managed to really screw up here.
I was casting a nice golf ball. It was going to be a handle for a tee and golf ball tool that will allow my father to stick the tee and the ball into the ground without bending his knees. Even had a depth setting with automatic opener.
The golf ball is going to be mounted on a carbon fiber rod of 21 mm diameter.
So I thought I would cast the ball with a core, but I had forgotten the correct way to make a core (something with white sand and molasses?) I had a piece of steel, nice and smooth and exactly 21 mm diameter. So I used that as a core, fully expecting it to be easy to remove.
Yep, you guessed it, no way in h*ll am I able to get it out. So I heated it up, no help. Froze it all and heated up the aluminium quickly, no help.
Now I drilled a hole throughout the steel, tapped it and filled the cavity with vaseline. I am freezing it again and then I will try to screw it out. You know the trick, force grease into a blind hole. But I have little hope.
I probably will have to cast a new ball, make it solid and bore it out. But my fathers birthday is in 2 days! Getting close.
