Thread: Conduit

I have tried this with no luck. But if you use the black pipe that you use for the garden sprinkler that will work. After it set use a bit of rod to push it out.What are you doing?

Haven't used conduit or black pipe, but have successfulyy made moulds from polythene cutting boards, either single blanks or 4 blank size.

The 4 blank size is cast as one block and then cut up on the bandsaw. Particularly good for swirls etc.

I also have 2 silcone rubber moulds (purchased from US) that cast 4 individual blanks, not cheap but excellent.

Boomeranginfo has a thread somewhere where he shows how to do that yourself. I looked at the economics and decided it was easier and cheaper to buy them.

Fred it is more fun making your own, I have made 4 now one that is a block of about 4, 4 single ones, one that holds 2 tubes for label casting and a bottle top.
David

thanks guys

the main reason i was thinking of conduit would be less waste due to it starting out round

not sure what to try to start with, i have some pearlex sets 1 & 2 coming as well as some powdered paint, both of these i believe can be used to color the resin, unfortunately they never arrived today so it will be next week before i can play

what sort of mixing container would you suggest??

thanks

I use plastic cups or any thing that will hold the resin. If you turn some resin to a U shape (ie off centre) you can poor silicon around this to make a mold. If you want to talk or need any help PM me for my number.

I agree David, and I have made quite a few out of cutting boards, but when I looked at the price that silicone rubber (the 2 part mould making stuff) sells for at Barnes it actually worked out more expensive. I have made several of the cutting board ones for casting "worthless wood" blanks. A $4 cutting board makes 3 or 4 moulds, and the cured blank releases very easily from these. Just remember to remove the mould from the blank before you post cure it in the toaster oven!

Did you see that on IAP. I have got silicon from Barnes before but get it cheaper now, I like the idea of the cutting boards if I had known about them before I would have given them a go. You could use them for casting with the tube by using a slide in one end to adjust for different size tube.

.

thanks again, i will be able to have a play at making a few different types of moulds over the weekend

the post cure thing, do you have to cook them for a while or will they cure by themselves over a week or so??? what temp and how long??

I made a light box with a 70w globe and it works fine for me leave for 24hours drill glue turn sand then post.

Yes, that gave me the idea, I make them slightly different though. So where do you get your silcone rubber now and is it much cheaper than Barnes?

The other thing the 4 blank block moulds are great for is the embedded strips type moulds.

No, you don't have to cook them, they will cure reasonably well in 24 hours, but they usually have a certain surface tack.

I have one of those little toaster ones in the shed from one of the cheap shops (Warehouse I think - $20), after about 3-4 hours (or overnight, whenever I do the cast) I take them out of the pressure pot and out of the mould and in the toaster oven they go, 30min at 120C and they are ready to serve

Do you mean ribbon casting?
There is a place hear in Perth that sells it but if you do a search on the net you will find some place cheaper I will ask where I get mine from if they have a shop near you.

So, how much do you pay there?

Yes, ribbon casting is the term I was searching for, this sort of thing
