    Announcement: Diffused LED ring light - New release.

    Hi Michael, There is no site to purchase the ring light. I send them directly to the buyers using some of the couriers available (UPS, FedEx, etc.) I am producing these products here, in Argentina, and there are not special instructions to import them to USA, at least on my side. Finally I...

    about air gravers

    Hola Onofre, bienvenido al foro! Todas estas inquietudes técnicas suenan como que quisieras fabicarte tu propio sistema de grabado. Hay algunos proyectos hechos con pequeños compresores portátiles para coches, pero no se que resultado han dado a la larga. Los sistemas de grabado profesionales...

    I would like to add that burning with sealing wax hurts a lot! So take special care and use gloves and eyes protection. Sebastian recommend in his video that you do not try to pull the wax from your skin. You must cold it in water and then dissolve it with some solvent.

    The newspaper test is to check the sealing wax flexibility. If it breaks you will need to add more tallow to the preparation and then repeat the test.

    You are welcome Monk. Thanks for the suggested translation. As for the recipes I think that the following translations may work: Recipe #1, 1 kg (2.2 lb) of rosin (colophony) 1 kg (2.2 lb) of chalk or industrial talc a bit of beef tallow Recipe # 2, the better one. 1 kg (2.2 lb) of rosin...

    Monk, I found a video by Sebastian Lopez showing two recipes to make sealing wax: The title "Como preparar lacre" would be How to make sealing wax, but with the purpose of using it to fix objects in engraving, so he is adding fat to the recipes. Hope this helps a bit more.

    Monk, I do not know if olive oil may work. In the recipes they mentioned animal fat. Unfortunately my English language is not good enough to assure you the exact name... cow fat? If I would will try to reproduce some of these recipes here in Argentina I would use cow fat.

    Problem with the use of commercial sealing wax to fix things is that it is very brittle. To solve this problem you must make your own sealing wax adding a bit of fat to the formula. The fat will do the trick making the preparation more flexible but still strong enough to fix the pieces very...

    I must say that you are wrong. Monk answered about the material Dimas use in the video and it certainly is not dopping cement or dopping wax. Although both materials may look similar, they are different. Dimas is using sealing wax for sure.

    Hi Monk, Dimas is using sealing wax, the same used with seal rings. The red square bars that you can see in the video are commercial ones. The other, the yellow one, he said that was prepared by someone for him but it is the same material. Jewelers in Spain traditionally use "lacre" (sealing...

    Roger, Although I have not signed any Confidential Agreement I must say that I do not know what my customers are doing with their machines. By the way, I am not producing the machine in series nowadays, just would assemble units on demand. Best regards, Leonardo
