If you’ll go to ICE, (International Construction Equipment) web site, in the hydraulic vibratory section they give a break down of how these hammers work. Iskysoft Registration Codes more. If you build one I wonder if you’ll need a clamp? I can only remember driving a few timber “posts”, but pulled thousands! Without a clamp I can visualize mushrooming the top of the “post” the same as an impact hammer does. Air / steam impact hammers, (picture) have a floating striker plate so the lump, (weight) doesn’t do too much damage. Diesel and some hydraulic impact hammer have a series of cushion plates with a striker plate to remove / limit the shock of the impact.
Mar 17, 2013 Here we are putting in post and rail fencing by simply sharpening a point on the post with the chainsaw, standing the post where we want it, slotting in.

When driving concrete “post” the same system is used along with 12-inches of plywood cushion placed right on top of the concrete “post”. I found a break down on the net of a rotary vibrator as build by 'cougar industries'. Not much to it really,just a short shaft with couterweights inside a cast housing.driven by an orbit motor. Problem is nobody there knows what size it would take to drive a certain size of post.only thing they said was that i would prob need 2 rotary vibes,1 turning CW and 1 CCW mounted foot to foot to get a liniar action. At 800 pop a piece is kind of pricy to start experimenting.
Of what i have seen,you dont need a clamp to drive them in,just a little weight,and it won't cause mushrooming either. My first thought was to use a plate compactor, but that may not be heavy enough. Then I thought if a guy could salvage the components out of a roller / compactor, the type you drive. Yes weight is the trick. I’ve used electric vibrating hammers to dive “post” before, they’re a lot heavier than a hydraulic hammer. For driving “posts” I’d rather have an electric hammer, but for pulling “posts” I’d rather have a hydraulic one!
Less crane needed! When pulling “posts” a good trick is to let the hammer move the “post” down with the weight of the hammer before ever trying to pull. Another trick with your post driving, if you get into hard soil rig up a pressure washer with a 3/8 or 1/2-inch pipe. Jam the pipe, (probe) into the ground next to the post. We called this an external jet, (we used 4-inch pipe). Not nearly as good as internal jets, but really makes a big difference in hard ground!
This won’t hardly work in clay, but in sand it’s like a hot knife through butter! There is many ways to skin a cat. I used to have acces to a big JD wheel loader yrs ago,i used it with the bucket full of concrete to push 200, 9 to 12' thick x 10' long powerpole stubs in the ground for my corrals. That worked slick as sh#T.I could have pushed them in flush with the ground by weight alone. The water jet could be usefull,i'll keep it in mind.I got sandy soil too. Hydraulics is on the tractor so why fart around with dragging other equipment along,sides that i got 15 mls of fence to maintain. Yea i could experiment with diff vibes, but i hate doing things twice or 3 times.
