- This is the first in a series of three videos showing my evolution towards water-bonded sand commonly referred to as greensand. The series may be viewed here • Escape from petrobond
I've been using petrobond and then my "refreshed" version of it (simply adding non-detergent motor oil to it) since I started casting two years ago. I've never liked the cost of petrobond or the smoke and smell that comes along with it. I've decided to make my own green sand. I talk about the sand and do my first casting with it.
Best tutorial I've found so far.
Nobody likes a show off Poppa P🙄!!
I have been using this stuff for about a year now, was thinking of switching to petrobond, thanks for talking me out of it 😋👍👍👍
Great work buddy thank you for sharing 😊
You know I've been planning the same switch, you have convinced me to switch sooner. On the kitty litter thing, you can buy powdered bentonite from pottery supply places, usually 325 mesh. Also sand usually at different meshes if you decide your sand needs different particle sizes added
You just saved me hundreds! Thanks for the valuable information
Great video. I've been casting for about a year, and the first lesson I learned is to protect the molding sand from sawdust. It's a real problem in my dusty workshop, especially when I make wood patterns at the same table where I mix green sand and pack the molds. It's very discouraging when you see carbonized specks marring the surface of a new casting. Thank you very much.
Sweet pour buddy!
That worked great Perry! Good to see that it worked so great for you 👍🏻 no more smoke and burnt looking pieces. I may have to try it again one of these days
Petrobond is so expensive. That is enough motivation to change to green sand. Thanks for the demo and chat. I have all my ingredients and will try to make some today. Be well...
You did it! Thanks for saving me all the time I would have spent making a ball mill to grind kitty litter. I'll repurpose that project into making a muller.
Nice work, I'm saving this for my future sand recipe
Nice work mate keep them coming
This is a great video! You did a great job of explaining how to make green sand and how to use it. I used to work for a disposal company (I.E. trash and pota-pots) and there was a section at the land fill where they would dump contaminated soil. That being said, you could call up your local landfills to see if they’ll let you get rid of the petrobond sand there.
I agree with Paul on the powdered bentonite. That’s what I used. You might try to mull the sand and bentonite to get it finer. The reason it looks grainy in your cast is the bentonite has coated your sand like a jaw breaker. That happened to me too.
Received my petrobond not 2 days ago, and then I discover this video lol!
A well done informative video- thank you.
Dude, great stuff here! Just starting out in the casting craft myself.
Very helpful content for us newbies ... I saw the cost of that petrobond, thought someone on you Tube must have their own recipe, wqatched a few of your videos, now I'm a subscriber ! Thanks so much for your great content
Nice casting!
