The formula for the kneadable concrete is as follows:

1kg coarse sand
1kg fine quartz/silica sand
1kg Cement
500g Cement based tile adhesive
2% by weight of fiber
600ml Water

Thanks for the recipe and the link. Thumbs Up

Now the main question.  If you make one of those, let it dry, and sling it against a target, what does it look like afterward?

Making clay projectiles is not difficult. I use two methods. You have to practice a method a bit, but then it is the fastest method. The other method is also very simple. You can find them in kitchen supplies. They are completely perfect shapes. Search for kibbeh maker. It costs little money. It couldn't be more perfect.


I tried a Kibbeh maker today but I had no end of problems with the unmoulding. Do you use anything to stop the clay sticking?

Tested today;
600ml of water was too much, I had to add more of the other ingredients. The formula needs a bit of revision, as it doesnt behave quite like clay does in my roller, I'm guessing a tad more tile adhesive. I ended up using just the lower section as a rolling surface to form the projectiles by hand. Once they are cured I'll see how durable they are.

I made a few more clay glandes well. They are great to shoot and I've already gone through 10kg of clay. A better constructed roller and a dosing scoop would speed things up, 2hrs of work for 20mins of slinging wasnt quite my intention Grin.

thanks for sharing the results. some of those concrete slugs are very nicely shaped( 2nd, 4th, 5th from low left.) If you plan on going for range shots consider sanding and painting the concrete.

nothing beats a natural source of stones
maybe steel rods cut with hydraulic cutters could be as fun (relatively cheap and more durable than stone/clay/concrete/lead)

Steel rods can be quite terrifying if they ricochet; especially if you shape them into biconicals

The main time killer was individually weighing out each lump of clay/concrete. I might try and build a trough type thing like you tried a while back, but out of a few offcuts of wood I gave laying around, sanded then sealed

I started with a trough which was also taking time then used a pvc pipe  thinking that a cylidrical shape would be easily shaped into a pill but the pipe was trapping air increasing times and inconsistencies. I ended up using a short pipe cut off that was the volume I wanted each projectile, I picked up concrete from the bucket with that and shaped the concrete by hand.

I'd say concrete wins only in price, it can't win in time spent.(just because it needs mixing)
The good with clay is that maybe you could fire it and be more durable than concrete.

I think the only way to have concrete win timewise would be to make up a PU / Silicone mould with multiple cavities then use a casting concrete formula with added plasticiser and accelerator.
