Today we started off the day we started off learning about the Ramset explosive power tools. I learnt that there are two main different types, the direct and indirect tools. The direct firing fires a single shot and must be reloaded each shot, it hits a cartridge and then the cartridge hits the pin or shank located inside the barrel. The indirect uses "magazines" of cartridges that are pulled through as the gun is "cocked". The cartridge is hit with a pin and explodes but it then pushes a piston, which transfers the force to the pin or shank with contact force.
When we used the ramset i expected it to be quite loud just like a real gun, but to my disapointment it was quite quiet. The handling force that is returned is pretty forceful though. It was interesting to learn about misfires and how it is standard procedure to hold the gun against the object, in the firing position for 10 to 15 seconds until removing it from the object. This way if misfires have a delayed explosion from the cartridge no damage is done to the operator or persons around the operator. It seemed like a practical and efficient alternative to tek screwing the timber plates onto the U-beams, but if you use pins it doesn't get enough grip on the steel.
After this we did an assessment on the sub floor, and although i didn't study i felt confident that i did very well on the test. I enjoyed doing the sub floor and because things were being taught to me verbally as we were physically building the floor i learnt and retained it with ease. I am certain i will have defeated Greg on the test and yet he studied and is still there right now, thankyou and good day sir mwahaha.
