Well done Cam, after 20 years, and getting back into the heavy casting work, would not be easy. You are also doing great work on bettering your machines to make them easier to use.
The Frytol tin took me back to the '70s, my family kept horses and we used those for mixing feed, and for water. In those days the fish and chip shops were keen to get rid of them.
G'Day Geaser, I got dozens of these tins over time from my local Chicken Star shop. Sometimes bought a family meal there and noticed them in the back of the shop. Asked if I could have a couple and was told take as many as you want cause they only get thrown out. Cam
Hi Cam, hope all is running swell at Viva, I’m guessing your foundry was in Melbourne? Enjoy watching the casting of anything metal, never had to do it though. So yes I watch those Pakistani vids on the tube a lot. I’m retired now after the big turnaround 2023, and enjoying life. I have 2 locos I’m building in my little workshop in Geelong West, 7 1/4 & 5” gauge. I’ve caught up but still not making boilers yet. Your vids are excellent, keep up the great content.
G'Day Rob, yep still at Viva and still looking after the Jetty, coming up to 10 Years in June. My foundry was in Leather St out in Breakwater. Myself and my mate Ian ran it as a part time business but it was almost full time given how many hours we spent there, we did Aluminium, Bronze and Cast Iron. My Father built a 31/2" gauge Evening Star which was a 9F Class. He was well on the way to completing a 71/4" Victorian H class and a three cylinder version of an R class with Baker Valve Gear. If you need a boiler built my brother designs, fabricates and organizes the inspections and all certs for Loco Boilers both in steel and Duplex Stainless Steel. His quality is second to none and every inspector who has looked at the many boilers he has fabricated (Australia wide) all comment that they are the best they have seen. He currently has a Heidi, a NSW 38, and a Black Five with a tapered boiler on the go. Cam
Hi Rob, regarding the boilers I make that Cameron replied to you about. If you would like to discuss anything about this, give us a shout out. Also, Cameron has a couple of clips showing him machining some of the Duplex Boiler Barrels and fixtures for me. Cheers Andrew
Hi Mark, yep it is Kbond (starts of cream in color) that has been well seasoned and used over time, it has turned black so no coal dust added. Check out the Kbond recipe here - www.afsinc.org/sites/default/files/inline-files/k-bond%20sand.pdf It was developed by the Kent State University to make a Petrobond type sand but at a much reduced cost, check out the article here - wiki.opensourceecology.org/wiki/Definitive_Article_on_K-Bond. I got a bag of the Bentone from a speciality paint producer in Melbourne arond 30 - 35 years ago (cost a bomb to buy) and have been using Kbond ever since for the finer casting work. I have tried to get more of it recently but can only buy it in large bulker bags. However I have now got a supply of the "Red Oxide" Petrobond at a very reasonable price. You can purchase it here in various quantities along with any other supplies from a foundry supply business in Melbourne. The guy is fantastic to deal with - www.greensand.com.au/ Cam
@@camatbattler2233 Cam, I was sent the raw bentone and the catalyst to make my own K-Bond by one of my YT viewers. I was able to make around 25kg of the stuff. Mine is quite red in colour but it is going darker as I use it. I still find it kind of funny to use. It seems to be a lot fluffier and it rams quite differently to my greensand. Maybe I need to add more IPA when I mull it. Regards, Mark
G'Day Mark, yes the Kbond certainly holds its body and is quite different to ram up. Put it into the Muller and add a small amount of 2 stroke oil. Allow to mix and add the IPA until your happy with the feel. You will find that you don't need to add any additional Kbond for quite some time. Was the Kbond red in color, this is the color of Petrobond due to the red oxide thats added in?
What type of clay is used in your petrobond/kbond? Bentonite? Have you ever used portland cement mixed with 2 stroke motor oil as a casting "sand"? I've tried it as a backyard casting hobbyist, and it gave a really nice surface finish with aluminum. Thanks.

Your Kbond sand looks completely different to mine. Did you add coal dust to it? I always thought it was red.
