Attach rotary dryer to post/raised deck

[londoncarl]

I have a challenge. My decking is about 1.2 metres high and I want install a rotary dryer.

The best position on the deck is next to a wooden post so my options are
a) fix to the post (how would I do this?)
or
b) somehow extend the rotary dryer into the ground below the decking. Any suggestion on what I can do?

Thanks

Carl
