[QUOTE="archive10, post: 890121"] Good progress! But I'd reconsider the angle-grinder thing if I were you. Put in the 3" pole for the summer-cottage-CM this afternoon. Got down to 60 cm with a spade, then 70 cm with hand-showel. Then I hit hard-packed gravel, had to use metal-bar (not sure of what the things is called) to loosen gravel all the way to about 80 cm. Would have liked to have reached 90 cm. But then I thought: 1) Gotta cut lawn and pack car before leaving for home. 2) 80 cm below / 100 cm above should be good enough for a ligtly sheltered position. 3) I have just hit bedrock (or a very large stone). Next step is probably dynamite. In therefore went the pole with rebar, and concrete. Kept the thing level with the trusty work-mate. Needed to keep checking verticality with a spirit-level as the concrete sets. Seems to be slight movements as the setting progresses. After one hour the pole was nice and firm in the foundation (but I did not want to overdo the leaning-on as the concrete was not quite dry yet). Will post mounting process when I return to summer-cottage later this year. Good luck with the digging... maybe the hour-and-a-half required employ the metal-grinder may compare favourably to what you spend on exploring the netherworld of your garden as it becomes juuuust out of arms reach... 8) [/QUOTE]
