Austin NJ Posted January 25, 2018 Share Posted January 25, 2018 Hi everyone, I was trying to find a topic on here about casting your own backing plates but could not find anything about it. I have a set of scale 40 Ford backing plates and was wondering if and how I could make an "unlimited" amount of them for my own personal projects by casting them in resin.. if that is the right term? If anyone has any tips on how to mold my own brakes that would be greatly appreciated. Thanks, Austin Quote Link to comment Share on other sites More sharing options...
Flynlo Posted January 26, 2018 Share Posted January 26, 2018 Austin, If you can post pictures of the front, rear and side profile of the parts then I'm sure that many on here can help. The methods for making the molds and casting will depend on the profile and details of the part. Quote Link to comment Share on other sites More sharing options...
GerN Posted January 31, 2018 Share Posted January 31, 2018 Since these parts are basically thin discs with detail on only one side, it would be simple to use Permatex red RTV to make slush molds, no mold box needed. I'll provide more detail if requested. Quote Link to comment Share on other sites More sharing options...
Austin NJ Posted February 2, 2018 Author Share Posted February 2, 2018 I got a mini casting kit so now I’ll be able to cast a bunch of stuff! Thanks for the reply GerN, I will look into that. I want to try making a dropped axle next, but I’m not sure where to start. Quote Link to comment Share on other sites More sharing options...
GerN Posted February 2, 2018 Share Posted February 2, 2018 If you try the Permatex, either build up thin coats (2 mm max) or mix in a little baking flour (about 1/20 by volume, max) or only the exposed surface of the RTV will harden.
