Hello everyone, I'm new here & to lure making, so I hope I don't make too much of a fool of myself!
I would like to ask for some guidance regarding some 7" resin lures that I cast yesterday, these particular ones where going to be a slow sink jerk bait. After speaking with the supplier of the products I needed, he suggested what casting epoxy resin I should be using & told me he already supplys this resin to other lure makers.
I have watched numerous YouTube videos of how to cast resin lures & pretty much followed them to a tee. I calculated the resin needed to create my lure which was 120ml/g total & added 10% 12g fillite (company's branded glass spheres), which by my understanding of the YouTube videos should give me a good buoyant lure.
After the resin lure had cured, I weighed it and it was 106g, I next tested it's buoyancy and it sank like a brick ha ha. I was quite confused by this, so I made another lure but added a 50% 60g fillite mix to the 120ml/g resin mix.
The result seemed good, it floated, however if I added 5g lead it sank slowly, bearing in mind I need to add 2 hooks, split rings and a through wire still, I would already be over, or near too the 5g with the hardware & if I was to make a topwater glide bait for instance it would already be sinking.
I would have thought, with a 50% mix of fillite glass spheres I should be able to add more lead than 5g to get my desired sink rate & swim action?
So can you help me please?
Are different brands of casting resins more or less buoyant than each other? I see on YouTube that a few lure makers use alumilite resin & I'm wondering if there are specific brands I should be using to aid buoyancy.
Does the 5g lead added that sinks the lure sound correct? They are my first so I'm unsure!
And could the fillite glass spheres that I'm adding somehow be different to the microbubbles that I've seen in videos, as in creating better buoyancy?
I really appreciate you guys who read and help me with this.
Thank you, Andy.
