sammy01007 Posted September 11, 2011 Report Share Posted September 11, 2011 I made a two, two peice molds today. One came out great. The other however is less than desirable. In a couple of spots the top half of the mold stuck to the bottom half, and tore the bottom peice when I seperated the two. I am considering trying to lay my positives back into the bottom mold. Filling the tears with fresh molding material (Oomoo 30), spraying the top peice with mold release, then laying the top peice back down. Hopefully the new mold material will fill and adhere to the bottom mold and fill in the imperfections. I made a cast and although useable, they could be a lot better. My biggest concern is I have very little Oomoo 30 left and if I destroy the mold, it will be a week befor I could fix it. So do I attempt the fix, or leave as is until I can redo the entire mold?

hillbilly1 Posted September 11, 2011 Report Share Posted September 11, 2011 They only problem I see is the seams the may not line up after the repair and may have defects. I see one of 2 ways 1 cut the broken part from the top and CA glue it back to the bottom you will wind up with a hair line but this is just short term sooner or later it will break on that same hair line or 2 hold out for more oomoo then cut the broken peace off the top as strait as possible then make the top the bottom reset the master release then pour a new top this will be your best bet it will give youu a better seal and seam over all Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted September 11, 2011 Report Share Posted September 11, 2011 If the problem is not in the cast face, then you have no problem. If the tear is in the cast face, then this is only a minor problem, as the fault on the cast can very easily and quickly be removed by sanding. Yes, it is annoying, but two minutes extra work is not a big deal. Dave Quote Link to comment Share on other sites More sharing options...
sammy01007 Posted September 13, 2011 Author Report Share Posted September 13, 2011 hillbilly, I like your idea of cutting out the defective area, and only repouring part of the mold. The mold is for a 4 peice swimbait. Only one section of the simbait is messed up, so I think I could just cut out that one section and carefully repour the one half of the mold.
