Saugerman Posted March 30, 2013 Report Share Posted March 30, 2013 I recently bought an old injection mold ,from a company that was in business in the 70's.It appears to be made of aluminum, that has dulled pretty badly. When I shoot it, it makes a dull worm. I sprayed oil on it before shooting it ,and it helps but before long they are dull again. What would be the best way to shine this old mold up? Other than the dullness it makes a great bait. Quote Link to comment Share on other sites More sharing options...
tupong Posted March 30, 2013 Report Share Posted March 30, 2013 Maybe polish it up with a little buffing wheel on a dremel with some cutting compond ? Quote Link to comment Share on other sites More sharing options...
carolinamike Posted March 30, 2013 Report Share Posted March 30, 2013 tupong is exactly right, your mold needs re-polishing. The shinyer the mold the shinyer the bait. Quote Link to comment Share on other sites More sharing options...
Saugerman Posted March 30, 2013 Author Report Share Posted March 30, 2013 That's kinda what I was thinking, It will be a pretty good job, it has 6 cavities. and sand blasting would probably hurt the mold. Quote Link to comment Share on other sites More sharing options...
carolinamike Posted March 30, 2013 Report Share Posted March 30, 2013 You definatly DO NOT want to sandblast it, and only polish the cavities. That way there is less chance for error. Quote Link to comment Share on other sites More sharing options...
Jig Man Posted March 30, 2013 Report Share Posted March 30, 2013 For really good polishing I use Semi Chrome. I put it on 1/2 of a Q tip in a Dremel. 1 Quote Link to comment Share on other sites More sharing options...
Saugerman Posted March 30, 2013 Author Report Share Posted March 30, 2013 Thanks for the replies, I will try the semi chrome. Have been working on it with some old polish that Iv'e had for a while. It is coming around ,but I think if I had some good polish it would do better. Quote Link to comment Share on other sites More sharing options...
JSC Posted March 30, 2013 Report Share Posted March 30, 2013 I am thinking that you have one of the "Sand Cast" Molds from back in those days. Dont know if you can really polish it up ... Could You post a pix of it ???? Quote Link to comment Share on other sites More sharing options...
Smallie Posted April 7, 2013 Report Share Posted April 7, 2013 The polishing compound mentioned above is Simichrome. Mothers aluminum mag wheel polish or Flitz are two others that would work. Quote Link to comment Share on other sites More sharing options...
Saugerman Posted April 7, 2013 Author Report Share Posted April 7, 2013 Jsc, the mold looks to be aluminum, If I can borrow a descent camera, and can figure out how to post a picture, I will try to put a picture on the forum, It has cleaned up some already, but I have not had a lot of time to work on it. Thanks again for everyones response. Quote Link to comment Share on other sites More sharing options...
Smallie Posted April 7, 2013 Report Share Posted April 7, 2013 If it is sand cast, the cavities will look like the cavity in a Do-It mold. Quote Link to comment Share on other sites More sharing options...
