Allumilte or Feather lite?

4 posts in this topic

I have finally achieved the action and balance that I have been looking for in my baits, and am ready to mold a few for some limited production.

What are the pros and cons on these two casting options?

Floats? Hardness? Accuracy in molding details? Holds screws well?

I will be using a two part mold system.

Thank you,

Billy

Alumilite has a density of 1.05g/cm3, this means that it is slightly heavier than water and will sink. Silicon microspheres can be added to reduce the density, but the more spheres you add, the thicker the mix and harder to pour. The viscosity without the spheres is 190 cps.

Smooth-on feather lite has a density of 0.67g/cm3, so floats. It is an equivalent density to beech. It has a viscosity of 400 cps, so is much thicker than standard alumilite resin. This will not allow much room for adding additional spheres, if at all.

As for your questions, I have not used either of these products yet, just done the research. I would not anticipate any problems with either.

All the work that you did setting up your bait for your required action, may well have to be repeated, unless your prototype wood was of a similar density.

Here are a few links:

I would say the feather lite was the way to go. Less hassle mixing the microspheres (not healthy, mask required), also the density will be (or should be!) consistent, which is the whole idea of casting.

The reason there is such a difference in the products is, Featherlite

already has microballoons in it.

Go with Alumilite RC-3, you will really like it.
