t-billy Posted January 2, 2012 Report Share Posted January 2, 2012 I was making a couple pop molds yesterday when the idea occured to me. Cement mix is cheap and there are several different varieties. I was thinking it would probably be stronger than pop,giving better durability to the cavity edges. Longer working time too,I would imagine. Anybody here ever tried it? Quote Link to comment Share on other sites More sharing options...
Travis Posted January 2, 2012 Report Share Posted January 2, 2012 I am sure it could be done if the right product was found or sifted but not for sure the gains would really out way a durhams rock puddy or POP mold to begin with. Once those are sealed well with an good epoxy they last a long time from my experiences. Some of used dental molding products and similar media to make molds but never really seemed to take off. I don't know if price, ease of attainment, or if basically ended up not being much better than the usual methods. I have several boxes of PermaStone laying around to use on a vivarium project and might make a mold out of it to see how it does. http://www.activaproducts.com/products/casting-mold-making-compound/permastone Quote Link to comment Share on other sites More sharing options...
Smallie Posted January 4, 2012 Report Share Posted January 4, 2012 Take a look at UltraCal30. It is a plaster with Portland cement mixed in. Quote Link to comment Share on other sites More sharing options...
t-billy Posted January 4, 2012 Author Report Share Posted January 4, 2012 Thanks for the input. I don't really have any serious issues with pop. It's cheap and works well. It's pretty durable once sealed with wood glue,but there's a long cold winter ahead here in Ohio. I think I'll pick something up next time I'm at lowes and do a little experimenting.

smallmouthaholic Posted January 4, 2012 Report Share Posted January 4, 2012 Precision CNC aluminum injection molds simply can't be beat for- 1- durability 2-ease of application 3- precision alignment 4- superior finished product 5- continuous productivity day after week after month after year They may cost more initially but save $and time in the long run.

I agree. Especially when it comes to injection molds. I have a growing collection of those too but, I also enjoy making my own molds/designs as well. For that pop and rtv both work very well. You can produce high quality baits with either. Neither one is as durable as aluminum but,both will last a long time and produce thousands of baits with proper care. I generally make prototype molds with pop. If I decide I like the bait enough I'll make rtv molds of it. Rtv molds are very durable and if I drop one it's no big deal, They're hard to damage and pretty much maintence free. I was just thinking maybe it would be possible to get results similar to pop with added durability and a longer working time with cement mix. I'll be going to lowes someday this week. I'll post results after I give it a try. Quote Link to comment Share on other sites More sharing options...
t-billy Posted January 14, 2012 Author Report Share Posted January 14, 2012 I Looked at several cement mixes. They all seemed too coarse/gritty. I'll be sticking with the pop/rtv. Quote Link to comment Share on other sites More sharing options...
