This is the first time i have posted anything so bare with me.
This red gum platter 400mm in diameter has a inlaid black epoxy ring which is iimpregnated with aluminium particles.
See attached image.

Pretty classy nine fingers!

Wonder how you'd go with eight ;-}

Nice work! Can I ask how you applied the epoxy? It is an effective combination with the aluminium as well

A groove was cut in the platter approx 14mm x 2mm deep.I removed the chuck with the platter still attached so as to pour the epoxy into the recess.
The aluminium I used was obtained from a metal turning lathe,which was sprinkled on and puddled in.
After the epoxy was cured,the chuck and platter was returned to the lathe for final sanding and polishing.
I have tried brass ,but does not look as good as aluminium.

Thanks for that. I have wondered myself about pouring "stuff" into grooves (paint, molten metals etc), but haven't tried it yet. But judging from the look of your effort, it is worth trying!

ernknot I learnt very early in life how dangerous wood working machines are.
I was a first year apprentice , over 50 years ago , no supervision while useing a spindle moulder.

Nine fingers,
Sorry to learn that, thought you were kidding with your name. I think there are times we forget just how dangerous machinery really is. Even with all the best guarding we still seem to get into strife at times.
Love the bowl!

Nine fingers,

Sorry also to hear about the finger, though if you are anything like some similar people I know you have long since adapted and don't even miss the finger!

Anyway, where do you buy your epoxy? I have looked in craft stores and also Bunnings and can't find anything suitable. I have thought of using surfboard resin with paint added to tint it, but haven't tried yet.

Thanks for any help,

Hei Ninefingers,
Great work, the epoxy gives an added dimension to the timber.

Fibreglass and Resin Sales on Kew St in Welshpool is the place to go, they have all the resins in various sizes and they do matting as well.

you can buy west systems and microfibre and then just but oxide colourings to which ever colours you want.

West Systems is a little over rated and over priced.
I used Fibreglass and Resin Sales gear when I was flying radio control aircraft and the stuff works - there is nothing like a mistake during an inverted low pass to test glue strength.

Hi SeanS, The epoxy I used was obtained from a fibreglass supply in Geelong
It is a surfboard repair resin ,250 ml tin .The black coluring came from them also ,but in future I would use paint tint.which you can get for nothing from your favorite paint store . Take in an old film container ,you only require a couple of mils.
Good luck with your project

I may be new to wood turning but plastic casting is somthing I do know about....!
There are basicly four branches of plastic famlies which are hand cast/poured etc.
1 Epoxy
2 Poylester
3 Urathane
4 Vynal
Each has diferant merits and also diferant set backs.

There are other plastics eg Butyl acitate acrylic nylon teflon etc etc
then just to confuse you there are plastic cocktails like PVA ABS which are a bit of all sorts of things but not hand mixed so not relavent here.

Epoxy is strong, easy to pigment slow to cure and seriously nastely toxic both in the gasses released and in the dust created in sanding it.
Basicly I use it as a glue/laminating product but avoid it for casting.

Polyester is the most common form of laminating resin (i,e what you get sold as fibreglass resin). It comes in many specialised grades eg winter/summer grades, laminating, flexable, gel coats, flow coats and casting resins.
It is toxic as well but slightly less so than Epoxy.
Mixing ratios are tight but do alow some flexability. It pigments well and accepts some addatives eg mettel powders perlessant powders etc.

Urathane now this stuff is "da bomb". It comes in a mirriad of types for diffreant aplications, It pigments wonderfully, accepts all the additives and is the most easy to use some cure in as little as 30 seconds! The fast cure times do cause bubble entrapment and so big castings need to be de gassed in vacume chambers.

Vynal is genraly not used as a free pouring hand mixed plastic but rather as a cooked type affair injection moulded etc.

One warning plastics are NOT cheap!

If any one wants to experement and or know more give me a call!

PS a realy helpfull company is Barns Products in Sydney who provide pattern making and sculpting supplies. The have great stuff and informative catalogues.
