Filling in wood holes/cracks: product? technique?
I woukd like to fill in wood holes and cracks on slabs as to maintain structural strength and provide a pleasing surface that can be sanded/polished with the rest of the wood.
A clear /transparent fill would be ideal..
Can anyone recommend the right product for this and where it could be purchased?
Would epoxy work?

Minwax makes a stainable wood filler. It's not bad for small holes and cracks. I don't know if it is available in Australia.

As you mentioned "maintain strength" then epoxy is your only solution aside from butterfly keys and wood patches. It's stronger/sticks better than polyester resin, and yes, it's available in clear.

photos of the slab would be good
but why do you need to maintain structural strength?
All the slab furniture I see is made from slabs as thick or thicker than the planks used to deck timber bridges -- you're not planning to use your slabs to support a B-Double truck are you?regards from Alberta, Canada

Definitely agree that Butterfly cleats or some kind of stabilisation should be used for large cracks as no amount of resin/filler etc will add much to structural strength.
If you want an opaque finish then Builders bog turbo mixed with cement oxides works very well,I have used this combined with black oxide on timbers such as marri and jarrah that have black resin veins.
If you want a clear fill then West stytem 105 resin works ok with the 205 or clear 207 hardener.
without resorting to colloidal silica filler the west system has very low viscosity so can easily "escape" so plug or tape any escape routes.
There can also be considerable heat build-up during curing of large voids.Last edited by mark david; 9th January 2016 at 05:38 PM. Reason: TYPOS
