My wife was making sauce the other day and I seen four tomato paste cans sitting in the sink. I decided to make a multi block soil blocker.

The nut and lock nut on the center all thread is for setting the block height. The distance between the nuts and handle, sets the block from zero to 3" high.

It worked well enough but it was difficult to get four consistent blocks. I made 12 blocks and it was quicker than making them one at a time but not anywhere near four times quicker. Come spring, I am not sure which one I will be using. John
