00:00:00.030 if you're new to the combination square and have questions about what it is and what it can do then  
00:00:04.470 stick around a combination square consists of a straight blade that slides along a handle and  
00:00:09.210 the handle is made up of an anvil and a shoulder which is at a 45 degree angle to the blade this  
00:00:14.670 particular combination square also is fitted with a leveling file an describing tool which we'll  
00:00:19.950 talk about later the most common two sizes are the 12-inch like the one I have here and a six  
00:00:24.930 inch version this measuring and marking tool has multiple uses let's cover seven of them the first  
00:00:30.420 and most common use is for marking or verifying 45 or 90 degree angles it's great for marking  
00:00:37.020 those angles on the face or the edge of stock and it works well at verifying and or checking 45 or  
00:00:43.410 90 degree angles on previously cut pieces it's also used for verifying and checking angles on  
00:00:49.140 power tools and accessories which leads us into the second use which is to aid in power tool  
00:00:54.840 maintenance and set up because of normal wear and tear on power tools like table saws and miter saws  
00:01:00.120 they only need adjustments made to the blades to keep them cutting at a true 45 or 90 degree  
00:01:05.670 angle with the blade of the combination square set to the end position it then can be slid up  
00:01:11.160 to a fully raised table saw blade to verify that the blade is indeed at 90 degrees to the table  
00:01:17.490 the combination square can also be used to check if the blade is parallel to the miter gauge slots  
00:01:22.710 which is very important to check and adjust if needed in addition if you remove the blade from  
00:01:27.660 the handle it can be used as a straightedge to check that the saw blade is in line with  
00:01:32.070 the riving knife and set to the proper position now that the handle is removed you can use the  
00:01:37.020 shoulder to check if the blade tilts to a true 45-degree angle you can also then take that over  
00:01:42.510 to the miter saw to verify its 45 degree bevel and miter the next use is a marking tool it's great  
00:01:49.260 for marking reveal lines on window trim like in my window casing video and it's also really great  
00:01:54.810 at transferring lines around a piece of stock on top of that it's a rock star for making long  
00:02:00.600 lines on the face or the edge of stock and you can use the blade by itself to mark out and lay  
00:02:06.450 out almost anything the fourth use is a depth gauge and last week's video we looked at making  
00:02:12.270 notches with a sir I saw and the tool I used to set up the depth and transfer those measurements  
00:02:17.140 to the other pieces was the combination square and that's what makes this tool so great is that once  
00:02:23.770 you set a measurement it's easy to transfer that measurement to multiple pieces moving on similar  
00:02:29.350 to using it as a depth gauge its next use is to set blade and bit Heights there are two ways to  
00:02:35.290 use a combination square to set blade height the first method is to slide the blade to the end of  
00:02:40.030 the handle and then place the handle flat on the table with a blade facing up then slowly lower  
00:02:46.420 raise the blade until you've reached your desired height on the ruler the other method which most  
00:02:51.580 people seem to like is to set the measurement first on the ruler so say to a half an inch  
00:02:56.650 and then stand the square up on the blade while using the handle as the blade height marker these  
00:03:03.490 two methods can also be used to set router bits and other tools in the shop no matter which way  
00:03:08.110 you do it just make sure the blade is at the top center of its rotation the last few uses number  
00:03:14.020 six and seven are not available on all brands but it's definitely worth talking about number six is  
00:03:19.600 to use the combination square to roughly level a surface using the built-in leveling vial this is  
00:03:24.970 a very small level and would only be useful on small surfaces however if you're trying to draw  
00:03:30.190 a plumb line from an unlevel surface like the top of this cabinet the leveling vial definitely helps  
00:03:36.310 to plumb the blade the last use is actually an accessory that fits into the handle and  
00:03:41.110 that's the scribe tool it's used to mark lines by scribing or scratching a mark into the surface of  
00:03:47.110 the wood personally I've never used the scribe tool because I've always had a pencil round but  
00:03:51.700 it got me thinking about what I could use this for and this is what I came up with if I needed  
00:03:56.770 to drill a hole every inch down the length of this board I would first find the center and  
00:04:01.270 then set up the combination square to mark a center line all the way down the length of the  
00:04:05.830 board I then would use the ruler and the scribe tool to mark each location by using the scribe  
00:04:12.280 tool more like a scratch al or a punch punching small holes every inch this way I would benefit  
00:04:18.250 twice from one step I would get both my layout marks and my starting holes at the same time the  
00:04:24.700 starting holes would then help me to locate the fit properly which helps to keep the bit tracking  
00:04:29.740 correctly it's amazing what happens when we take the time to think about like what I just did  
00:04:34.810 what's possible with the tools that we have and I encourage each one of you just do that with all  
00:04:39.550 the tools that you have in a shop you'd be amazed at what you come up with and what's possible with  
00:04:44.020 what you have thanks for watching this video as always if you have questions you can leave  
00:04:48.400 them below you can always email me thank you for joining it's good to see you see you next week
