TIPUse the jackhammer to crack the concrete, not to punch holes. If the chisel bores into the concrete without cracking it, stop and try another spot. Getting a stuck chisel out of solid concrete is a cursing waste of time.Rent the jackhammer''s smaller cousin, a "chipping hammer" ($30 to $40 per day), for lighter tasks: breaking up a few airnailergaugerecommendations square feet of basement floor for plumbing work or chipping ceramic tile off a concrete floor.Brad nailerCOST: $50 per day with compressorBENEFITS: Better results with less time and effort. A series of accidents involving air-powered nail guns last summer brought home the fact that the productive and powerful tools are airnailergaugerecommendations and airnailergaugerecommendations also highly dangerous and need to be handled with respect. In the most tragic case, a framing nail punctured the heart of carpenter Camillo Juandelos on a home construction site in Ocean View, Md., in July, ending the man''s airnailergaugerecommendations life at the age of 25. Police said Camillo''s brother Jesus was holding the gun that fired the deadly nail.According to reports in the Delaware News-Journal, the accident took place as the two men were framing new homes in a development airnailergaugerecommendations in Ocean View. Jesus had been airnailergaugerecommendations bending over a airnailergaugerecommendations stud wall using the air nailer, and then straightened up and turned to call his brother. But Camillo was not on the other side of the room airnailergaugerecommendations as Jesus thought; he was already standing right behind airnailergaugerecommendations his brother. Camillo made contact with the nose of the nail gun, triggering the bump-nail mechanism and taking the nail in his chest. "It was just a strange thing that happened," Ocean View Police Chief Kenneth McLaughlin told the News-Journal, "a very, very unfortunate accident." The young carpenter died at the Peninsula Regional Medical Center in Salisbury, Md., after being evacuated by helicopter.A nail-gun accident in Mississippi had a happier outcome, reports the Biloxi Sun-Herald. Stone County, Miss., contractor Duncan Hatten was crouching down to nail a 2x4 block onto a column when he lost his balance and fell against the airnailergaugerecommendations nail gun, which fired two quick nails into his heart. "I just figured I was gonna die," Hatten told local TV station WLOX. "I told my coworker to tell my family that I loved them." But the two framing spikes had narrowly missed major blood vessels, and surgeons were able to remove the nails from Hatten''s heart in a two-hour operation.
