Good question! The answer is a razor saw. They are sold at hobby stores or hobby supplies places. Cost around 5 to 7 bucks. There are different sizes you can buy. It is a strip of steel with very sharp teeth and has a handle formed on the back edge so you can saw. Great tool for accurate cuts on balsa for model making. I think the brand is X acto. That is what I use a lot and find it will cut many things better than jewelers saw blades because of the stiffness of the blade. Hope this helps.

This thread brings back some old memories.

I tried this once about 35 years ago and ended up with 2 pieces because I pored to slow. bricks

I still have the 2 pieces. Maybe I will put my parts together some day for a vacuum caster.

The next time I go to the city am going to a pet store so I can try again.

Bless

 I had fun making this tutorial and am happy that you enjoyed reading it. I will do more castings in the future and post some pictures of them for your viewing pleasure. I actually need to buy some more cuttlebone myself as that was the last piece I had left from last years batch. I have a few ideas for future castings I would like to try out and I hope that some of you will try this sometime too. It can be addicting, be warned! LOL ... All the Best, Marty

If you have a pet store that sells large birds, they will also have large cuttle bones, I get mine from a bird seller for about 3.00 each and they are about 10 inches long.

travelerga have you done any castings using this method with the cuttlebone? I plan on ordering some this week sometime and try out some new ideas I have been thinking about. I just got a new Durston rolling mill and I am rolling out some of the plates I cast along with some wire from casting square rods from scrap silver. These will be used in  some other fabrication  work. I plan on trying out casting some Celtic style Trinity pendants with the cuttlebone though. I did one last year and it came out good. It sold fast, wish I took a picture so I could post it. But anyways,  I learned a few things and the next one will be better. I hope that others will give this a shot and post some pictures of their successes or failures, as this is fairly inexpensive casting method to attempt to do.
