You’ve probably seen decorative joints in concrete before, from faux paving stones to circular medallions. You may have even wondered how they’re made. After all, saw blades only cut in straight lines, right?
According to Bob Harris of the Decorative Concrete Institute, not really.
Harris shows you how to cut both round joints and precise straight joints with walk-behind saws and angle grinders in this ConcreteNetwork.com video. (You may remember him from another ConcreteNetwork.com video that we featured two weeks ago on cutting control joints in concrete). Since this is a video about decorative concrete, there’s also a section on dyeing and acid staining. Watch it now, and let us know what you think in the comments section.

There are times when you want to attack a door’s hinges instead of its latch side during forcible entry, say Lt. Samuel Hittle of the Wichita, KS Fire Department and Capt. Chad Dailey of the Kansas City, MO Fire Department. (We agree; we’ve had videos on attacking the hinges of outward-opening and inward-opening doors on this blog before) Maybe the occupant’s loaded the latch side with lots of security devices, or you want to remove the door so that your lines won’t be obstructed.
That’s why they wrote this article for Fire Engineering. It tells you how to attack door hinges on outward-opening doors with saws (our personal favorite) and the irons. Whether your department emphasizes these skills in their training or not, this is still a good article. Read it now.

We’ve shown you how control joints in concrete work. Now we’re going to show you how to make them with cut-off saws.
You can make these cuts with walk-behind or early entry saws, of course. However, some surfaces like stamped and other decorative concretes demand smaller cut-off saws, according to Bob Harris of the Decorative Concrete Institute. This video from ConcreteNetwork.com shows you how to do cut control joints in these surfaces with these saws. Watch it now, and let us know what you think in the comments section.
Lt. John Hayowyk, Jr. of the Passaic, NJ Fire Department has been running a three-part series on accessing the roofs of Type 3 construction buildings over at Firefighter Toolbox. He’s already covered using the roofs of adjacent buildings and ladders. Today, Hayowyk wraps up his series with one of the most dangerous and least desirable ways to access roofs: fire escapes.
This article covers choosing which fire escape to use on a building, sizing it up, climbing it safely, getting your tools to the roof, and then climbing back down. Oh, and if you’re not checking out the fire escapes in your district on a regular basis, both for yourself and for potential victims, then you just don’t get it.
