Make a Simple Jig for Cutting Complex Miters/Angles | How to Woodworking.

hey guys welcome back to the channel before we get started with today's video i want to talk about a couple things real quick first of all i did a tedx talk that's right somebody let me in front of a stage it was pretty much fun actually we ended up doing it in the shop but if you'd like to check that tedx talk out there'll be a link in the description box below that you can do it and would definitely be interested to see what you have to say about us i'll be watching the comments section of that video next up i've been getting a lot of interest in the makers playground signs so we made some little versions and these are available on my website again i'll put a link in the description box below we'd love to have your support and if you can do that that's great if not that's okay too we'll keep making videos before we get into today's video there's just one more thing i want to let you guys in on the secret of life and the next winning lottery numbers thank you very much for your time guys i hope that was helpful and um let's start the show everybody welcome back to makers playground hq i am izzy and i have a fun one for you today we're getting a little bit of jiggy with it so let me set the scene for you guys i have a friend who's a millwork installer picture a friend right here and don't let her look slow she will work circles around most boys i know now right now she's working in a hotel down somewhere in the atlanta area and they're installing a bunch of fancy wall panels and stuff but then you need to do some trim so what they're doing is they're installing a wall behind the entry desk and it's some kind of fancy pants thing with a bunch of really cool panels that go in there but they have this piece that they need to have a double miter in or a convex double miter that goes right here so think of it like this this piece is three-quarter inches in this direction but it's one and seven eighths deep so it's pretty deep and the angles here are not like a 45 so this is a one side is like a 32 and the other side is like a 58 degree angle and they need a way to cut those with job site tools therein lies the problem so when you're not in a fully equipped shop cuts like that can be fairly tricky so today we are going to show you how to build a simple jig to make that kind of cut relatively quickly [Music] so this is not a job site table saw but it's what we've got so that's what we're going to use now if you have a job site table saw and you do trim work or you know finish mill right work it's really good idea to have a small table saw sled for that table saw because you can do a lot of things with it so we're going to do is accessorize our table saw sled to make that cut quick and easy so as a point of reference i'm going to use material that i would have on a job site and the tools that i would have on a job site i'm not going to use anything fancy so we're going to kind of pretend like we're in the situation that they're in and we need to rig something up relatively quickly so we can get the job done so i'm starting with a piece of scrap plywood this is some three-quarter inch plywood and i'm going to cut two lengths you know probably about 12-16 inches because i want some support for that piece that i'm cutting and let's make it 18 inches [Music] i'm going to cut one more piece of 18 inches that i'm going to cut down into slats [Music] so the first thing i need to do i'm basically making a table that's going to lift up like this so i want to be able to put the slats like right there and i'm going to put a pivot point right there so i can lift it up which means i need to remove a little bit of material from here and here so i'm going to do that again on the table saw and then we can start putting this thing together [Music] so we're going to assume since they're pros and they're on a job site they're using power pro screws so you don't need to drill holes hashtag not sponsored wink wink now this doesn't have to be super sexy you can use a nail gun as well if you've got one already plugged in all right so this spot we wanted to pivot and now remember how i was just bragging on power pro screws about not needing to pre-hole pre-drill but because i am so close to the edge here i'm pre-drilling so what i want to do is lift this board up just a small amount so it kind of offers a little bit of free space under there i don't want it sitting tight i just want it up a little bit so i can make a nice little pivot spot there that this will easily move up and down so in any way you can use any number of things to create that spot there um in this case if i had change i would use a couple of quarters but i don't but since i don't have any quarters in my pocket i'm just going to use a couple of washers you could use cards business cards folded pieces of paper a chunk of cardboard any one of those things as long as it keeps you fairly consistent across the surface of the material like this so you'd want to mark beckett so this is three quarters of an inch wide and i want a central pivot point so i would mark 3 8 inches down and i would mark 3 inches down here and 3 8 is in over but i'm just going to guess same on the other side and then run a couple of screws into those positions now if you wanted to make this for your shop and you wanted to get super fancy you could do that but like i said we're pretending like we're on a job site and we need to get this done in a hurry all right two final pieces of this puzzle make sure it moves up and down freely it does yay so now we need some way to hold it up in its position once we find an angle there's a couple of different ways you can do that the simplest way is to just put a piece here and a piece here or just to put a piece loosely on the back that you can screw in here or you know whatever position you want it in and i think that's the route we're going to go so you just want to put a loose screw in the back of here doesn't have to be super tight if i can you know do this without it coming flying out of my hand [Music] so to keep it loose i'm just going to go ahead and put it in the piece before i do that make sure it's flush with the board that's probably a little bit more than that so that way it's loose and i can move it to wherever i need it and run a screw in there and hold it in position now once this is fairly stable so once that screw is in position that'll hold that where it needs to be now the last thing i need is a fence along here to go ahead i can either go that way or that way that way i can clamp a board onto that fence so um for for argument's sake or just to get this done quickly i'm going to go ahead and screw one right down there now you'll notice i'm these are inch and a half screws a three quarter three quarter which aren't really three-quarter and three-quarter so i'm going at a bit of an angle so that piece doesn't pierce and i'll do the same here [Music] and now we can still move this up and down so what i need to do now is cut a piece of material that we can cut one of those little double convex miters on let's do that next so all i have is some 15 16 alder in the shop that i can cut down to use for this to do this demonstration so we're going to plane it down real quick so this is completely unnecessary planer shot to throw in the video just so i can show off my new quick lock system that we'll have on the market in a few weeks over here as long as we're showing off our quick lock system let me show you another accessory we're doing right here check this out so you all know how what a pain these are not anymore and these lock in place once they're in they're really really really really sturdy i'll have more content and videos coming out about that stuff soon let's get the plate in [Music] okay so what's really cool about this jig is it gets rid of all of the math for you as long as you know one angle let's say the angle we want is that 32 degree angle we mark that on our board let me do it right here so i've marked 32 on here and if i move that up here that's going to be a 58 degree angle because that is what's left over with 90. so i'm taking 32 subtracting that from 90 i get 38. so how the way we set up the jig is we're going to find our center mark here so we know that's our center mark ish it's close and then we take our the jig we just made and we throw that on a flat surface and this over here and we find our line let me let me move this where you can actually see what i'm up to all right so now what i want to do is take that line right there and i want to put it on a flat surface and then i want to bring that up to a piece like this that tells me hey i am i am right at that line right like that then i'll mark it here and put my screw in now because this is just screwed together and i don't have a really good way of controlling that i'm just going to take a piece of material and shove it back in there that way i can take my time and make sure that i've got my line exactly where it needs to be now if you look back here in order to adjust that i just move this block in like that until i get exactly where i want to be dude that's it right there so before i do anything let's mark a line here so i don't lose my place in case my board drops and then i'm going to come back over here and add my second screw now we have now we have a sled with that angle so let's take this over so the first thing i'm going to do is raise my blade so it trims everything off right here so i have a really good defying spot i'm going to cut that extra bit off with my sweezen saw and if you don't have one of these on a job site you might want to ask yourself why don't i have one on a job site because they're super handy in lots of weird places all right we're getting there so now if you're this is like really hard because we're in this little weird area so i'm going to bring this line to my center to my center mark right there so that's the the line that we're going to take off there's our center mark and then i'm going to throw a clamp on this all right i'm going to bring my blade down so i'm not cutting all the way through the material a couple ways you can do this is you can put a mark right where your center line is right there on the on the jig bring it over to your blade and then raise the blade up to that line or you can do what i'm about to do and just raise the blade slowly in little increments until you get where you're happy with it [Music] okay so now that i'm happy with where the line is i'm simply just going to move this over by about a sixteenth of an increment [Music] and repeat that process [Music] so you can tell i need to bring my blade up just a little bit more but you all are getting starting to see the idea here so this is a perfect 90 degree angle and i only had to do the math for one side and now it sits just like it's supposed to so now that i've got this and i want the inverse of this on this end i can still do i can still use this jig right here what i'm going to start by doing is finding my center point and let's say i'm going to measure from this point right here to the center point of wherever i want that measurement to end so this is how i will measure the length of this material so now i'm going to bring that up to basically where the saw is going to come through and it's going to cut this off at that angle so i'm going to go ahead and raise the saw blade up so it'll cut it'll cut through most of that and if you needed this to be a little bit lower you could make it out a half inch so you're not quite so high above there probably a caveat that should be added [Music] now i need to bring sure i need to make sure my blade is back down to the same position it was before so to do that i'm just going to flip i'm just going to flip the material back over and bring it down to the to the blade lifts let it back down so i'm transferring that center line right onto the material here i'm going to bring that down to the table saw blade height right there throw my clamp back on and start the cuts over [Music] and now you have the inverse of that cut so i hope that made sense to you on the on the back cut the front cut's easy or the um the convex angles are easy the concave or the concave the conch i've been saying convex that's a concave concave angles are easy the convex ones take a little bit of figuring out but it works so uh if you're ever in a situation where you need to do that you're on a job site you don't have your bandsaw you don't you're not setting up in a full equipped shop it's a really easy way to do it all you need is a table saw sled and a jig that you can build in probably five minutes if you're not recording a video and i you can like be the rock star on the job site for that day so i really hope you enjoyed this video i hope it made sense to you guys and um oh i guess i'll see you in the next oh wait i'm supposed to say subscribe and thumbs up you know what i'm talking about see you guys in the next video
