Auger Extension

[sodamo]

I have to sink nine 4in pipes 56 inches deep in 12 inch holes as supports for my tractor/utility shed. Requirement is 1/2 the above ground height has to be in the ground (112 / 2 = 56). These are 12in diameter holes and will be filled with concrete. My 12in auger for 3pt phd is only 45 inches, 2inch shaft. Is there such a thing as an extension available? Perhaps a home-made solution? I anticipate fairly easy digging as I've hand dug about 20 holes to the 3 ft level by hand about 300 away and figure similar conditions. Guess I could get the last 11 inches by hand /forums/images/graemlins/frown.gif, but prefer not to.
Thanks

This company lists PHD extensions for Danuser PHD's.

What make and model PHD do you have?

Will you be able to lift it high enough to clear the hole? Other than that little issue, I can't see any reason not to add an extension /forums/images/graemlins/smile.gif

Thanks for link.
Unfortunately, I don't know the make/model and it's 6000 miles away right now.

It's only 9 holes, if I have to add/remove an extension "in the hole" I don't see that as too much an inconvenience.

Here's the followup to original post.
Due to mods, the holes had to be 60 inches at the finished depth, rough depth 63-64 inches to allow for a concrete base.
I looked for an extension. The local Massey dealer could get me one from Gearmore, for $100 - and 5 week wait for no cost shipping. I could get in 2 weeks for additional $80 shipping. This was too much for my nine holes.

I bought 2 16 inch lengths of pipe - 1 2" and 1 11/2" at Home Depot and fabricated my own extension - total cost less than $15 including the 1/2 inch bolts.

The following pics resulted.

First is 6 of the 9 holes laid out and hand started (to get through packed rock and weed cloth)
