This one turned out much better, although there is still room for some (lots of) improvement.
I dyed the cones first, under pressure, then set them up in a PVC tube and poured in the resin, then into the pressure pot for approx. 24hrs.
Upon removal from the pot there was some bleeding up through the cones. So back into the pot for another 24 hrs. Then sat outside in the sun for 3 days.
I then removed the block from the PVC and sat that in the sun for another 2 days. By this time I just couldn't wait any longer so I cut the blank in half and drilled a 10mm hole down the centre.
THERE are times in a mans life when he should stop, but I continued drilling even though the cones were still soft and there was some tear out occurring.
This morning I filled the blank with thin CA, let it soak for about 10 minutes then poured out what was left of the CA.
I found a couple of bushes to fit into the holes and turned it down to about 5/8in diameter and had to CA the outside to fill a few holes where the cones had torn out.
Sanded to 1800 then buffed.
Somehow the next lot of cones have to be hardened or stabilised before casting.
WHAT DO YOU THINK?????????
