Don, I guess I don't understand "External Power Supply."

Gary, I started a little brick project yesterday. It's been foggy as all git-up for the past week or so. It doesn't clear up until around 11:AM

Somebody slid on ice into a brick wall with lettering at the entrance to a residential neighborhood.

It so happens I did the job 12 years or so ago. Before I take anymore repair jobs, I'm going to make sure that it's not one of my jobs. I used an air hammer gun 4 or 5 hours yesterday and 4 or 5 hours again today.

The mortar was so hard some of the bricks would break before the mortar would come off, as I was trying to clean them. I can't get new brick locally to match.

I left some of the sections that broke off alone. I just cleaned them up along the edges where i new to replace them in the wall. It's too hard to get them apart and clean the brick.

Some of the sections are 8 to 10 bricks stuck together. I hope this works! This is a new experiment for me. I make good money doing this but man it's rough. I'd rather be tooting my sax!
