Apdriver Posted January 13, 2015 Report Share Posted January 13, 2015 Within the last few days, I have read about polishing the sandcast molds. I have never done this and find it interesting. Will the guys that do this share their methods for polishing your molds? With the smaller cavities and limited work space inside that cavity, I see this as a bit challenging. Thanks.....Bill...

bass100 Posted January 13, 2015 Report Share Posted January 13, 2015 I just use a dremel and various bits. Quote Link to comment Share on other sites More sharing options...
robalo01 Posted January 13, 2015 Report Share Posted January 13, 2015 First Tape the edges so you don't create a flash like, start with about a 120 grit and work up to 1000. Then use a polishing compound. I make my own bullet concave worm sinker and polish then like this. The sinker falls out of the mold easier and you get a very smooth mirror finish.

cadman Posted January 13, 2015 Report Share Posted January 13, 2015 I use a dremel, with a rubber tip and then rubbing compound followed by finishing it off with toothpaste. 1 Quote Link to comment Share on other sites More sharing options...
CNC Molds N Stuff Posted January 21, 2015 Report Share Posted January 21, 2015 Toothpaste is an amazing final finish polish. I've been told spit and cigarette ash work fairly well for final finish polishing as well. 1 Quote Link to comment Share on other sites More sharing options...

I've heard the same thing about cigarette ash as well, however the smell is a tad nauseating. Quote Link to comment Share on other sites More sharing options...
