Now I have painted all the small ducks. They are so cute! These are the last ones:
The work on the big duck mold is progressing. I have finished the latex mold and have made a support for it using plaster bandage. I have made it in two halves to make it easy to remove it. On the first half I made a small ridge about 10 mm in from the edge so the other half gets good support. When it had hardened I trimmed it with my dremel so it looks nice.
When the two halves was finished I needed something to keep them together when casting. I used a strap for this but needed something more to hold it in the right position. I filled a small plastic jar with plaster and put the head down in it. I had put a thin plastic film on the head so it didn’t got stuck in the plaster.
Now I was ready to try it out! The mold and the support worked very well. It was easy to cast and everything went well. When I removed the mold, I saw that the beak was a little too thick in the upper part because I hadn’t put in a support for the beak in the two halves.
Now I have fixed this and I hope the next big duck will be perfect!

They´re soooo cute and I love how you´ve colored these small ones here. Looking forward to see the big ones all finished too.
Do you sell the duck molds?
No, I’m sorry. I only make molds for my own use.
Could you make concrete rubber ducks that weigh from 100-300 lbs? Hey again! This is the second year of my benefit strongman competition for veterans and first responders and we have paired with Jeep to have it at their JeepFest here in Toledo which draws thousands of people to Toledo. I want to do a stone load but have the stones look like the rubber ducks people put in their jeeps! Is that possible?
That idea is awesome! If you’re going to cast such big ducks, the mold has to be really big and strong. Maybe you could make a mold out of fiberglass, two halves that you can screw together. Search the internet and you’ll find several descriptions of how to make larger molds. I wish you good luck, with or without ducks! 🙂
