Wooly Posted January 3, 2011 Report Share Posted January 3, 2011 I am looking to modify the 5/8 cavity in the do-it screw-lock football shakey head. I was wondering if I could fill the cavity w/ JB Weld then put a 3/16 football head into the mold to form a new cavity. If anybody has any experience -- their insight would be most appreciated. thanks, Quote Link to comment Share on other sites More sharing options...
airbrushextreme Posted January 3, 2011 Report Share Posted January 3, 2011 I have used JB weld for this also it lasts forever and can be chipped out if you decide later I have built molds out of jb weld all by itself so have at it Quote Link to comment Share on other sites More sharing options...
cranker Posted January 10, 2011 Report Share Posted January 10, 2011 Read my post about permanent mold cavity filling here.JB weld works great and is perfect for projects like you are talking about.Just let it set for 10 to 15 minuted or so after you mix the two parts to allow it to start setting up or when you make your new cavity with the jig head it will want to stick and pull out some of the JB when you remove the jig you are using to form the new cavity shape.
