Forgive me for popping in after a long absence, (still here regularly, just lurking) but has anybody any photo examples of items made with machinable wax apart from the test cuts shown here? How would the machinable wax behave for use with lost-wax casting? |

Weston, I believe the wax companies make a wax that is specified for lost wax casting. http://www.trycut.co.uk/ These do one called jewel wax but I have never tried it. When Aidie was here last week he brought a sample of the wax he had cast as shown on here, I also had a sample of what we had cast for the shows doing loco wheels and some of the blue stuff from Trycut above. In terms of hardness mine using the thumbnail test mine was the softest, followed by Aidies, then the Trycut I put the difference in mine and Aidies down to the candles, Aidie used paraffin wax and we used surplus candles from Ikea which were a 2 part wax, inner and outer coatings so I don't know which one of the two was the better material. I can get an example of a mouse chewed loco wheel later if you want, these are about 3" in diameter and machined with a simple D bit to get a draught angle on the spokes. They are not for a loco, just a machining exercise to do at the shows. John S. |

This wax would be good for making the original model in, but I wouldn't try to use it as the wax that gets melted out - it's a bear to get properly molten, and is considerably more viscous than pure paraffin wax. |

Just popping in to say, I am watching with great interest :thumbup: Keep up the good work as I'm learning lots in this thread :ddb: |

U'all just reminded me of wax baths that physiothearapists use to treat folks with arthritis. If u are doing lots of smaller castings a 4 Kg bath that plugs into mains power can be purchased new for around $200. Seen heaps when I used to do the rounds of physio clinics in my past life. Not sure what temp they run at. They do take a while to melt parafin wax, but it is its kept at a nice constant temp and it can be left unattended. Did a quick incanink search, didnt see any power ratings for the element....sorry. |
