Drill Square holes in steel with REBAR -NO SPECIAL TOOLS needed

today I'm gonna show you how to put square holes in steel with no special tools pretty much just nose machinist tools no way there's no meals just regular crap that everybody has in the garage want to find out how keep watching how did I make a piece of rebar put a square hole in a piece of quarter-inch plate easy let me show you so we're gonna do is take a piece of rebar grind four sides flat so we have a square the same sized hole that we want we're going to sharpen the edge harden it and it is a broach we can hammer through this is one I made before it's kind of quite a few holes a little beat up so we're gonna start over from scratch I'm going to make a new one and you can keep sharpening and editing this once you make it one time just keep going hey this is a piece of half-inch rebar you can barely get a three-eighths you know a 3/8 square out of it this is a piece of 5/8 rebar and you can probably get about a 7/16 square out of it you want to be able to get a half inch square out of it barely not maybe but it'd be closed it's all we're gonna do is chuck this in the vise the hand file if you wanted before rebar is actually not that hard before you actually harden it but it hardens amazingly well so now this is the matter of I'm just gonna take my flat disk and we're just gonna square it up there we go roughly 3/8 by 3/8 the more time you spend on this the better but but we're they're good enough for a carriage bold or whatever now what we're going to do is most brooches you see people make our interior brooches and they kind of just push the metal out this is actually going to shave the metal off the outsides and push it towards the center so now we just need to dish out the center in there and so you actually need you could drill it with the drill bit and then kind of fine-tune it you could use a file or something else like that I actually like to use a dremel with the really small wares that we're just a really small blade because then I can just use the contour of the dish of the blade just to kind of ride in there you don't need huge but I'll just write it around in there and I'm going to keep each one of these four corners as points and so each one of those need to come to like it's gonna look like a king's crown essentially like a four-pronged king's crown dished dished every single way with these little four points as the as the crown so I'll play around with that now just taking around like chainsaw file I'll show you the contour in a second there you go not perfect but that's what you want sharp edges a dish like I said you can even kind of use a drill bit and kind of drill in there first but chances are you're gonna do a little off-center I think the grinder works a little bit better a little bit of a file it'll just combination everything try to make your walls as flat as you know as straight as possible and now we're just going to harden it and we only want harden the tip because we're hammering on this part and so we don't want to make any of this part brittle so it's just the very tip and so is this matter of heating it up till it's red hot and just quenching it in water you see Waddell as well but I think water actually makes it even harder and it'll actually retain its edge really well we use two propane just propane huh this into water just a tip we want this to be soft so we don't want any of that we just want that to cool off naturally it's actually not that hot but we want to make sure we kept our nice edge and it feels like we did because now you won't be able to run a file across this this right here is going to be harden that is nice and hard that whole you know the whole probably half to three-quarters of an inch is nice hardened steel now and it holds up really good so now it's just a matter of let's make the hole if you're this far in the video don't be a square make sure you hit that subscribe button got a piece of quarter-inch plate here we'll just come over and we're doing a 3/8 square hole so first thing we need to do is just drill a 3/8 hole so wherever now it's just a matter of actually taking our brooch setting it over where we want to drill the hole where we want to approach the hole and then it's just a matter of just hammering at home first we're gonna start out on a flat surface like this and then once it gets through a little ways we're actually gonna move it up to so it can push through you know like the vise jaws or you could lay two flat pieces of metal just so you have somewhere to push it through if you do on too wide of surface obviously hammering I'm gonna start bending the whole piece of metal but we'll just start it out right here put the safety glasses on because we do have hardened steel down here and if you get it too hard sometimes it'll tip off a little corner or something like that it can fracture so if you do that after you harden it with water it depends on the the the rebar some is harder than others some has different content than others but if it chips off just resharpen it and heat it up just like warm it up till it's hot not red-hot and then let it cool and that will anneal it a little bit and it shouldn't chip off again we'll get it right where we think we want it I don't know if you can see but it's starting to push the material into the center you can see we're getting there this is such a small piece I am starting to bend it just a a little bit but you can see it's there and it's mushrooming out the other side so now it's just a matter of driving it all the way home square-hole cares bull you could touch it up a little bit with a file I guess if you wanted but we damage the tip a little bit but I mean once you have this square shank right here it just takes a second to resharpen it up and you just go again you know this is quarter-inch this is thicker than you probably will ever need to draw one in generally you're you know both time I do this I'm doing in 8 inch max maybe you know maybe we're going up to 12 gauge or something but you know you could I see no reason why you couldn't drive this you know my ops sharpen a couple times why you can drive this through 3/8 or even 1/2 inch steel if you just you know if you're just really determined you might want a bigger sledgehammer but you you know the bigger recess you do in here the better but you need to keep the integrity of these teeth 16 gauge steel fueled my approximate 3/8 hole we'll put this around it we can put this on just 2x4 backing or some sort of hardwood Carter would any sort of wood I guess hardwood would sink in last line that up we're all the way through there was some deformation a little bit not bad I mean it's only as good as the diet that you make just to see if it's possible here's a 5/8 hole that I just barely made and what I did is I just ground off one side so I essentially just almost made it a chisel there's a little camp chamfer in there but I just took it here here here here here here and just went around maybe two maybe three times and just cut it all the way out and there was no issue whatsoever so hey thanks for joining me in the shop if this video helped you out help me out thumbs up leave a comment below read them all or even better yet subscribe see you guys soon bye don't be a square subscribe hurry it's not gonna last forever bring here come on bring here I gotta go that far for it
