I made a drop hammer piling rig for a job knocking 300mm steel casings in the ground 3 m deep and made the weight out of an empty oxygen cylinder cut the top off welded the end of a hydraulic ram on for the lifting eye then melted lead into it.
Now that weighed just over a tonne and by god that could shove them in for such a small weight

I was studying my mates Bryce a couple of days ago with a view to making something maybe a bit simpler. Why do the feet on the Bryce and other professional machines adjust on rams when the mast also has adjustment for angle. Couldn't the machine sit on fixed legs even at an angle then use the mast ram to plumb it?

Hydraulic legs are great, I've go a Protech with them, great for rough ground, can lift up to slide the boom out, then plum.

The legs on the Protechgenerator are on the sliding carriage then? I'm sure the ones on the Bryce are on the main frame but I'll have to go back and look. ie drop the legs then side shift and power out to the rear as required.

The adjustable legs on machines the Bryce make a big difference to overall stability over the machine and the tractor it's mounted on - needed with a hammer weight of up to 800kg on a Bryce. They can also help to increase mast height.

Bob c and gav0994, those machines look good. Do you have more pics and some dimensions? Did you have side shift and and rearwards movement. (Not sure what you call that!)

25 deg of angle movement each way
600mm of side shift
but no rearwards movement

I was considering building a post knocker as a winter project and priced up a 200kg solid round bar 380mm diameter 205mm long and it was £300+vat with local steel supplier

On the machine I built it has 600mm side shift, no idea what angles the mast moves in and out at as I've not measured it but it is plenty for what we need. Also got hydraulic top link to angle the whole machine forward or backwards. No backshift on it as I couldn't justify the extra cost for a 7 lever spool valve.

This post driver on the front of the FW looks pretty good, pity there's such a small report on it inside, the best pic is on the cover. I like his idea for the back shift.

Making a post driver at the minute and just finishing off the post cap / holder . What's the opinion on the little spikes to hold the post . Should there be 1 or couple spread apart / or none at all . Would the hole they leave not let water in to the top of the post ? .
