T-posts in hard ground - a hack

[oosik]

I had about 65 locations where the exposed bedrock made me use 2x4 - "L" posts. My neighbor has a commercial air compressor/jack hammer. This will be the final year where we replace the last "L" posts with T-145 steel posts. That jack hammer makes a 2" hole, about 16" deep, fairly quickly.

How big is the jack hammer? Do you have any info on model/cost.

Bill - the actual hammer is pretty big and it's heavy. The air supply comes from a three cylinder diesel mounted on a trailer. It's the type you see at highway construction projects. It is DEFINITELY not a homeowner model. He tows it around with his pickup. When he gets here - I tow it with my tractor. He let me try the hammer once. Got down about 6" and he took over. The major concern - getting the bit stuck in the hole you are drilling.

There is compressed air hissing everywhere - dust and rock chips flying all around. It makes quick work of our basaltic lava.

Another hack. I didn't want to start a new thread just for this, and thought it would fit in here.

That's pretty slick. A very cute girl and a slick way to pull a T-post.

I see powered post pounders for around $300.

Powered T-post pounder

Wow! Solar powered and 110v AC. They really know what they are selling.

I have some exposed rock on my property. I bought the largest hammer/demo drill Makita makes (SDSmax) Purchased a 1.5'' drill bit and drilled the rock and hammered the T post into the hole.
No need to cement in as the 1.5'' hole is a very tight fit for T post.
You just have to knock the plate off the T post

Our clay soil doesn't give up a T post once shes been in the ground for a fw years. Takes a big tractor to pull em out and they take a lot of bonded dirt with them.

pretty inovated method... The way I always done it was with a chain, I wrap it around the post three time and use a farmer jack or FEL to pull it out.

that's a trick of the trade... if you want lots of views just use a pretty girl.
