Phenix72 Posted May 28, 2015 Report Share Posted May 28, 2015 hi, someone has tried to produce jigs with tungsten powder and resin? If you are with what results? Quote Link to comment Share on other sites More sharing options...
Jigatollah Posted May 31, 2015 Report Share Posted May 31, 2015 You need very high pressures and temperatures to form tungsten powder into whatever shapes you need. Not worth the investment in that type of machinery. Quote Link to comment Share on other sites More sharing options...
CNC Molds N Stuff Posted May 31, 2015 Report Share Posted May 31, 2015 (edited) I think he was talking about simply suspending tungsten in a resin matrix, not forming sintered tungsten. I considered something similar with lead at one time, but haven't had time to do any experiments with it as of yet. Here is an old conversation on the topic right here on http://www.tackleunderground.com/community/topic/8438-pouring-tungsten-jigheads-and-weights/ Edited May 31, 2015 by Bob La Londe 1 Quote Link to comment Share on other sites More sharing options...
CNC Molds N Stuff Posted May 31, 2015 Report Share Posted May 31, 2015 FYI: Small quantities of tungsten powder are expensive. Around $75-80 per pound retail. Quote Link to comment Share on other sites More sharing options...
Phenix72 Posted May 31, 2015 Author Report Share Posted May 31, 2015 Yes, powder of Tungsten and resin. The powder find cost $70,00/kg and resin $ 30/kg. Recently protocol talking about 97% of metal in the final density. Quote Link to comment Share on other sites More sharing options...
CNC Molds N Stuff Posted June 22, 2015 Report Share Posted June 22, 2015 I've done some research on this idea. I can not find tungsten powder much cheaper than finished tungsten sinkers. Maybe in huge quantities, but I haven't ask for any quotes. Quote Link to comment Share on other sites More sharing options...
Munkin Posted June 24, 2015 Report Share Posted June 24, 2015 Yes but so far I cannot get a high density head and the powder is expensive. I made some shakey heads and they are only about 75% as dense as lead. Allen Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted June 24, 2015 Report Share Posted June 24, 2015 Allen - that is good information for all considering this method. It is unfortunate, but about what I was expecting. I was hoping that it would at least match lead, but the gap between the grains is averaging out pretty high. The only way to improve the numbers is to compress it somehow, but I don't know how to make this work for any shape other than a simple cylindrical weight. I guess it is back to the depleted uranium then Dave 2 Quote Link to comment Share on other sites More sharing options...
Munkin Posted June 24, 2015 Report Share Posted June 24, 2015 Pouring a mixed two part epoxy is tough because of how thick it is. My next plan it to use a syringe to try and inject like you mentioned. I think I can get this to work but it will not be a way for a hobbyist to do large production of tungsten heads. On a good note I was able to make brown, GP, and black heads by mixing soft plastic dye into the epoxy. Allen Quote Link to comment Share on other sites More sharing options...
FrogAddict Posted January 4, 2016 Report Share Posted January 4, 2016 (edited) I have a question about this. I know the post is old but I hope someone can answer me. I'm looking to add tungsten powder to resin and poor a bass jig head using a two part mold (1/2 oz.). I'm being realistic here and I am hoping to get 3/8 oz. out of a 1/2 oz. lead jig sized mold. What do you guys think? Will the resin be too thick to pour? Will I be able to achieve the 3/8 oz. weight?
