Sorry meant to add a pic to show how I use the stone slabs. One lag bolt holds the caterpillar in place. Western red cedar 4" fence post.

Got it, now lets say you start to make about 15mm hole; how deep a depression do you get in about one hour? This just to get an idea how long it takes to make a hole let's say 4cm deep/long.

Constant work ?
You'll be right through it in forty minutes.....well that was something grey and hard and had been rumbled about in a glacier and we lifted it from the loch foreshore.
Sandstone and you'll be through it in quarter an hour....if you have good grit
