All Soil Block Principles remain the same, except this makes round cakes, not soil blocks. Makes a nice round 1-1/4" soil block. Total cost= $7.00-10.00 with easily found parts at any hardware store.
Try this "blocking mix" or soil cell mix:
These ingredients work well for soil cells rather than soil blocks. Other than these low compression machines, DO NOT use vermiculite in a Ladbrooke soil blocker. The blocker will just crush the vermiculite rendering it useless as an aerated medium.
Warning: The whole soil block art & philosophy is about root growth in a compacted soil block. Anything that looks "much simpler or easier" can't compact soil enough to adhere to our science of soil blocking. Do it right, or don't do it at all.

If you are unable to acquire the parts in their sizes or cut them yourself, ask if your local hardware supplier will cut them to size for you.
Making the Plunger
Special Note: I was able to tap all the drilled holes to have threads so I could screw everything together. If you do not have access to a tap, some type of water resistant durable glue will help hold things in place.
**Filler for Part A – in order to have a flat surface on the top of the soil cell, the 1 1⁄4” cap needs to be filled with something hard. For my project I chose Resin. Which lends itself perfectly to making a hard surface that is easy to clean. In the center of the resin is where I inserted the wood screw, which gives the soil cell a divot in which to place a seed. The filler will ultimately secure C on to the end of B, which is inside the bowl of A. Make sure the measurements are where you want them BEFORE filling. If G is too snug, make the hole in E a little larger, but not so it is sloppy. Over time it will become less snug.
