[Music] alright welcome back folks in this video I want to take a few minutes to talk about the difference between hand tools and power tools and I also want to talk to you about hand tool safety so before we begin we should ask a simple question what's the difference between a hand tool and a power tool my students often say a hand tool is a tool that you hold in your hands and a power tool is a tool like the tool back here that you turn on well this isn't always the case there are power tools we hold in our hands too if we take for instance the hand saw this hand saw is a hand tool I hold it in my hands and I'm actually gonna use the power of my body power this off so I cut the piece of wood with this saw and my body I can use a circular saw which does the same thing I'm holding this on my hands and it'll do the exact same thing the difference is this tool was powered by a motor and electricity so power tools are tools that are powered by something other than our bodies whether it be electricity or gas or air the list goes on but right now I want to focus on hand tools sometimes I ask my students what do you think is more dangerous a hand tool or a power tool and students will often say power tools well the truth is any tool that you don't know how to use safely is dangerous and in fact I think more people hurt themselves with hand tools than they do power tools and part of its psychological that is if you see that circular saw spinning and you hear it moving it seems dangerous to you if you take this handsaw which no they're fairly ubiquitous we see these around quite a bit it doesn't seem as dangerous but you can still hurt yourself with a hand tool hand tools deserve just as much respect as power tools so you can see here on the table we have the hand tools that we commonly use in our woodshop a screwdriver which I'm sure you've all seen a hammer chisel a rasp hand plane and a handsaw and of course there are many others too but these are the ones we most commonly use what I want to do right now is talk a little bit about safety when you're using these tools so first the most important thing we need to remember is that you always need to wear what safety glasses and you know what I forgot to put these on when I cut with that circular saw I don't know if you noticed that but first you always want to make sure you're wearing safety glasses even when you're working with hand tools it's very important to keep them on so number one always wear safety glasses ok the next thing I want to talk to you about is about how to cut safely and to do this I want to tell you a quick story so when I first started teaching which off I had a student and this particular student was working on a cutting board they had just finished the cutting board or finished gluing together wood for the cutting board and it looks something like this let me grab I don't know if you guys can see here but here's a piece of wood three pieces have been glued together and there's some glue that squeezed out onto the cutting board well this student brought the cutting board to me and asked me what the next step was and I told the student I want you to take the cutting board I want you to clamp it down to the bench and I want you get a paint scraper and scrape all the extra glue off something like this does that make sense well this is what the student did they took their cutting board they set it down on the bench and instead of grabbing a paint scraper they grabbed a chisel now the reason they grabbed the chisel is because they weren't paying attention to the names of the hand tools we used in the shop and they actually thought that this was a paint scraper but this is not a paint scraper it's a hard and piece of steel with a razor-sharp edge on it they took the chisel and they use the chisel to scrape the glue off the piece of wood now let's look at what happened here when they brought the chisel over to the piece of wood they started scraping the glue now the wood moves what did the student forget to do the student forgot to clamp the piece of wood down to the table if they had just taken the clamp and clamp it down to the table right they then could have used the chisel to carefully scrape the glue off the piece of wood now this is not the ideal tool to use to scrape food but it'll work right they could have done this they could have kept two hands on the chisel instead they do this the wood started moving so what did they do they became a dolphin club hey you see where this is going now right so now they have chisel sharp objects in one place and they have their body in a position where tool can cut it and they're cutting towards themselves so you've got this scenario and sure enough they scraped it a little bit scraped a little bit and they found a big chunk of glue so they lean all the way back they put their weight into it and they forced the chisel through the piece of glue into their hand not good so we never ever force some tool or overload cool because when you do this you have all your weight and momentum behind the tool and you can cut yourself the same would be true on a power tool if you're pushing a piece of wood really hard into a power tool and you have all your weight behind it your hand could then go into the power tool so quick review here number one if this student had clamped the piece of wood like I asked they then could have kept two hands on the tool if the student were using the right tool for the job the paint scraper instead of the chisel they would have been much safer if the student had not put their body in a position where it tool can cut it and cut towards themself they would not have cut their hand and if the student had not forced it there's still a chance they could not have cut your hand there handy so all those rules are really really important when we're working with all tools but especially hand tools there's something else I see occasionally in the shop which makes me very scared people working towards their leg or their body right this can be very dangerous I see it a lot with screwdrivers setting screws and a piece of wood okay if you have your hand behind a screwdriver while you're setting a screw into a piece of wood you can stab yourself with a screwdriver that's very dangerous as well so you need to keep all these things in mind always consider where your body is in relation to the tool that you're using the next thing I want to talk about is the hammer we occasionally drive nails in our woodshop with a hammer we sometimes use the nail gun as well but let's talk really quickly about hammer safety number one when you're nailing two pieces of wood together you always hold the nail in the hand you are not hammering with you're going to push the nail into the piece of wood and you're going to gently pound the nail in as soon as the nail is set you're going to remove your other hand from the nail because if you are pounding and you miss and hit your finger it is really going to hurt that's a nice way of saying okay so when we pound the nail in you always keep your eye on the nail just like you're hitting a ball you guys keep your eye on the ball you always keep your eye on the nail and you get it straight in the claw of the hammer is only used for pulling nails out of a piece of wood we never use the claw for separating pieces of wood or for doing other things like that okay it's just used for removing the nails from the wood so quick review remember always wear safety glasses make sure you never have sharp points or sharp things pointed at your hand and you position yourself and tool where it's will can cut you that's always very dangerous always use the right tool for the job make sure you are clamping the piece of wood you're working on whether it's with a bar clamp or a bench vise make sure you always clamp the piece of wood that you're working on and when you're using a hammer watch out for your fingers okay I look forward to working with you guys soon in the shop I hope you learned a little bit from this video see you soon [Music] you
