Has anyone any thoughts?

This is the only thread I have found in the forum:

viewtopic.php?t=614&start=15

Lead isn't the preferred option, but it's pretty clear some of the big boys are using additives, the epoxy is no longer clear (semi-opaque and or other colours)

I'm not thinking UV additives, more enhanced performance for the epoxy.

What kind of "enhanced performance" are you looking for exactly, Rich? Are you having issues that you're trying to fix, or just looking to experiment for the fun of it? This seems like a little bit of overthinking to me, but you know how I tend to be conservative on things like this

Wood as core material comes with certain inherent issues to resolve. If so, then I'm really thinking of this in terms of increased durability. The second issue, is a greater ability to absorb impact - particularly important if you want to continue using virgin veneers.

Make sense?

Largely thinking out loud (again), prompted by all those videos Falls has made available.

There are many solids. Most manufacturers use dyes that match the plastics. So, I guess a nano-particulate that aligned while under a slight electric current during layup may be beneficial...depends.

By additive, you mean something like carbon nano-tubes suspended in the epoxy?

No. Thats a waste of time.

Background colour - yes, but it accounts for all the different colours on view?

Thanks for the tips, hints and website.

Sounds like there's a bit of experimenting going on.- groovy

some of the ski epoxies are "rubberised" aren't they. Is that the kind of thing you are talking about?
People have had varied opinions on adding things to epoxy. Some on this forum have been pretty stridently against it.

That is a link to hpr epoxies in NZ. Kingswood use the hpr5 (scroll down to rubber toughened epoxies).

Yes

- its this type thing. I'm thinking about additives on the basis that I can stay with the same epoxy.

Interesting video: http://www.leang.com/academics/project_movies.html , but I'm wondering about uniform dispersal. Perhaps I should play music to my press? Any advice 393?
