Another barn build

You are in a battle of wills. You against the rock. It's going to be worth it in the end, but I understand how frustrating it is to battle the land!!!!

Years ago, I was thinking of buy an excavator and an old timer told me to never buy one that had been used for jack hammering. He said that they have been abused more than any other machine, and the reason they are selling it is because it's too worn out to fix.

Ha, good thing my heads full of rocks too

I have heard the same about excavators, and it will be interesting to see what the final toll is on mine. After this it likely won't get many hours of use. So far all my bushings seem to be holding tight.

I just pulled out the stone that was the worst remaining at 3' or so above elevation, so today is an "I think I'm going to make it" day.

I looked into that, but they require 1-1/2" holes drilled 80-90% of the way through the rock. That's bigger than any drill I have can handle, so I'd have to buy or rent a drill, then spend a bunch of time drilling. I figured hammering from an air conditioned cab sounded better.

Oh, and I just replaced the chisel AGAIN. There goes another $700.

With a new one being $700, I'd be using up a bunch of grinder wheels to repoint the old one(s) - at least for spares.

This looks like quite the project. More than you planned on?

I would also think about repointing the chisels earlier than later. Don't let them get so flattened off before repointing. Yes it would be more often, but not as long at the grinder each time. Jon

I don't think I would use a grinder to sharped those bits. I would find or buy a carbide bladed chop saw and set it up in there and have a new point in less than 5 minutes.

That old bit is still good at work we would hammer that bit till it was a nub. My boss would flip out if I change that bit out....

I knew it was full of ledge, but it has definitely been more work than I expected. Moving the building is the obvious alternative, but doing so creates a bunch of other issues long term. So I’d rather put the time in now and have the building in the optimal location.

Would that work where a machinist said it was too hard to cut with a mill? I was wondering about cutting with an abrasive saw rather than grinding it down, thinking that would be less material to remove. Those point faces are 5”, and the chisel is 3” diameter. So it’s a lot of material to remove.

So much seems to depend on the material I’m trying to break up. Splitting granite, and breaking out the stuff around the big granite pieces definitely goes faster and easier with a good point. Softer stuff still breaks up easily a blunt tip. But I’m new to this and learning as I go.
