Resin additives?

[chuck1]

Question for you resin people, is the swarf from key cutting any good for resin filling for cracks?
As I saw all the mess at Mr mint key cutting the other day, got me thinking!
I would like to have a dabble with some resin as I have been impressed with others work with resin.
Thanks in advance

Probably finds its a bit coarse, I use powdered metals instead

Yes a bit course, so will not appear as a solid metal when cast, but can still be used. Will result in a bright brass spots, where actually turned, amongst darker unturned brass background.
