How to Make a Spline Jig for Picture Frames and Boxes

How to Make a Spline Jig for Picture Frames and Boxes

Want an easy way to strengthen up mitered corners on picture frames and boxes? Check it! This is the second video in a multi-part series on picture frame making. You can find the other videos in the links down below. This here is a real simple and easy to make jig that rides along your table saw fence and allows you to cut splines in picture frames. Just using glue on mitered corners may seem good enough but over time as the width of the wood expands and contracts with the seasons the joints will eventually break. And that’s why you need splines. Unlike a lot of spline jigs this rides along the fence and not in the miter slot which means you can place the spline anywhere you want and even cut wider splines by moving the fence and making multiple passes. Setting the blade height is easy since the corner sits just a hair above the table and the two guides easily clear the blade. Let’s get started! I’ll measure the height of my fence and cut two pieces of baltic birch plywood to that measurement. Then I’ll measure the width of the two pieces and the fence and cut the top on the tablesaw. I’ll attach the top piece by lightly clamping the two side pieces to the fence and then glue and screw it together. Making sure it slides nicely along the fence I then attach the support board to the assembly. You’ll also want to make sure it’s square to the table before gluing it up. You can use any material you like but here I’m using MDF that will be used to hold the the picture frame in place. Although this step is not necessary I’m cutting 45° miters on the ends as you’ll see why shortly. I’ll then clamp down a drafting triangle to the support board and use a speed square to make sure it’s at 45°. The drafting triangle is then used as a
guide for the two MDF pieces The 45° angles we cut earlier align with the edges of the board. Again not necessary. After the MDF is clamped down I can then remove my drafting triangle and once everything dries we’re all set to cut some splines. Setting the blade height is just a matter of setting the picture frame in the jig and raising the blade to the desired height. I then slide the fence over and visually align the blade to the center of the frame. I suggest clamping the frame to the jig as you run it over the blade. I like to shut the saw off between every cut just to be safe as I don’t like handling material over a spinning blade. Over on the bandsaw I’ll then cut out the spines and glue them in place. A nice fit and doesn’t need to be too snug. No clamps necessary. And when they dry I just sand them down flush. You can also use this gig to cut spline keys for boxes using the same steps. I suggest using a full kerf blade with a flat grind. A thin kerf blade will work just fine and if your blade doesn’t leave a flat bottom cut, don’t worry about it too much. The tiny little gap that it may leave may not even be noticeable and it could always be filled in with sawdust and glue. Well thanks for watching! This is a multi-part series in picture frame making and I encourage you to check out these other links. Well that’s it! Be safe, stay passionate and make something!

    i will be building this. thanks david!

  8. Matthew Diresta says:

    Great jig!

  9. Dustin Penner says:

    Who are the jackasses that disliked this video?  You could tilt the blade and do some cool angled splines too.

  10. Danny Shackleford says:

    I love the simplicity of this jig. I am going to build one for myself. Though I will have to modify it some to work with my homemade fence. However, if I'm not mistaken, didn't you say at one time splines were unsightly? Lol.

  11. Ali Salih says:

    Nicely done. I am wondering if it would be a good idea to add a handle to help to glide it easily? 🙂

  12. Christopher Demetrick says:

    I like to know I am not the only one that turns the saw off between cuts for the same reason you mention. I am heading to the shop to make one. It will be perfect to run splines on the corners of the boxes I like to make.  

  13. Crafted Labs says:

    Nice shirt!

  14. Bob Phillips says:

    I really enjoyed this video. I think I might make one of these to frame some of my old artwork. Thanks for sharing the jig sir. Awesome and simple.

  15. Rock-n H Woodshop says:

    Now that is a great jig.  I use mine quite often.  Great way to simplify it.  Mine was a little bit different but I like yours very much.

  16. Lazy watchsmith says:

    Love it!

  24. Jeffrey Kuhn says:

    Good job buddy! Are you going to bring the bongos back?

  25. Joe Dimitrijevich says:

    Where was the: "How…are you doing?" At the beginning? That's my favorite part! It's like your catch phrase! Lol Great simple jig! Love it! Thanks!!

  26. Mark Hazlewood says:

    Thanks, David.  That is the simplest spline jig I've seen.  Mine is about 5x bigger and very clunky.  Now I gotta build this one.

  27. Stone and Sons Workshop says:

    Good idea! I will definitely be making one of these.

  28. Andy Friedt says:

    Wow, that is super simple, but high quality just like the video. Definitely going to be building this. Thanks for the idea!

  29. Tim Starr says:

    I really like this jig. I plan on making one when the weather breaks. I was also thinking of putting in a slot in the center to install an adjustable cam clamp. That way the piece can be clamped closer to the table. Love your videos. Keep it up.

  30. Studio Zaccaro says:

    Good idea, man. 

  31. Greg Machar says:

    Very clever Mr. Picciuto, very clever indeed! Still loving that 80's music. Love your stuff!

  32. m4u11 says:

    Another jig to add to my to do list.  Nice work.

  33. John Turner says:

    Very cool jig. I like!

  34. Upper Cut Woodworks says:

    @Drunken Woodworker  Looks good! Everyone is so obsessed with dovetails for boxes but splined miters look great and are strong.

  35. Euripedes Reis says:

    Mais um projeto simples e de grande utilidade que embeleza e torna resistente uma moldura para quadros

  36. Ant Mallett says:

    Great way to align the supports using a speed square and drafting triangle. Nice job.

  37. James Campbell says:

    very nice

  38. john cooper says:

    All your videos teach something useful. I love the pace you use and not a lot of useless dialogue. Keep it up! 

  39. Brad Huffman says:

    Great stuff.  Completely unrelated question about your glasses.  Are those prescription shop glasses @ 3:00 or something that you added to keep the dust/chips out?  Thanks!

  40. Gold63Beast says:

    Hey drunken woodworker I been looking and looking to see what wood comes out at 0:15. It's really red and been wondering what kind of wood it is. Thanks.

  41. charlie-g says:

    nice added to project list!

  42. Joe Basement Woodworking & DIY says:

    Good stuff dave! I made one a while back .not like this one.gonna tackle this one tomorrow and get rid of my old one. Is there a certain height the to 45dgr pieces need to be or does it not matter how high or low they are? ? Thanks man!

    WHERE U BEEN??:)

  43. Ken Dometriosis says:

    Just what I was looking for! Good job dude!

  44. bora sok says:

    | like this Video So much . thankyou for made thế viveo

  45. Atelier Good Wood says:

    I tried this today, works great. Thanks for the idea 😉

  46. Charles Holland says:

    making this right now, thanks!

  47. NW says:

    Very clever!
    I'll be building one of these for my box making. I like this design much more than the miter slot type. More compact and easier to store.

  48. Jamie Siebold says:

    just finished making this job. it was super fast and works perfect. thanks for the video, man!

  49. Leaping Lemur Craftworks says:

    Nice and simple and effective – thanks, this is going on my to do list.  Scott

  50. Tim Bruno says:

    Thanks for this video! So simple and looks easy to use. Just in time for a frame project I'm making right now!

  51. kimbow555 says:

    Gee! Great tools make it look so EASY! But not everyone can afford to buy expensive tools. Mind you, I now have a Table Saw, so am looking forward to making all sorts of things.

  52. kimbow555 says:

    Great video. Thanks.

  53. kimbow555 says:

    Can you tell me what type of Drill you use Dave?

  54. Bruce A. Ulrich says:

    How did you get it to where your work piece is just above the table of the saw? Did you use the drafting triangle for this purpose…slightly extending it past the edge of the board? Cool jig…I'm going to make one.

  55. John Cole says:

    Really sweet jig

  56. Ricardo Steigleder Endres says:

    Ótimo! Obrigado

  57. Lynn Lacey says:

    Thanks for a simple to make jig. I like that you can see where the blade will hit the frame, easier to center the cut with this setup. Thanks again

  58. Dhir Am says:

    Put the spline jig into the basket..

  59. Chris C. says:

    Dave Pachuto, you are great!

  60. scott mclean says:

    Hy after seeing your spline jig I was hoping you may be able to do a video on building a box/comb jig please. your video was really clear to understand

  61. Kevin Schwy says:

    done and dusted!! great deal man! easy peasy!

  62. Derek Jacobson says:

    Glad you referenced this video today. I need to build this. Thanks.

  63. Toni Hagen says:

    Great jig, tossed my old spline jig out, this one is so quick & easy to set up!

  64. Bobby Oates says:

    What is the measurements on your spline jig. Great job Bobby.

  65. Rok Podlogar says:

    i can't for the life of me find a speedsquare here in slovenia lol

  66. Emory Gilbert says:

    How high off of the table are the MDF pieces?

  67. John Roth says:

    Love your tutorials, thanks

  68. DanKmake says:

    I sort of miss these glasses David! 🙂

  69. Ken Bickel says:

    does this work with bigger frames or would you need a bigger jig for the different sizes of frames?

  70. Logan Brunson says:

    great video – just what i needed thanks. Also i found this funny…
    3:23: "I like to shut the saw off between every cut, as I don't like handing material over a spinning blade"
    4:11: Doesn't shut saw off and handles material over a spinning blade

  71. Jeremy says:

    Next build, thanks!

  72. Jason Carlin says:

    Any recommendations for a flat bottom blade? I've never had one before.

  73. Brett says:

    Love the attention to safety.

  74. Brett says:

    Classic glue & screw

  75. Jeremiah's woodworks says:

    Awesome video

  76. The Thirsty Craftsman says:

    Hey David, I'm a fan of your new stuff but found this vid when looking for info on a spline jig. Just want to congratulate you on how far you're come, the info you share is still as good, but your production, confidence and lack of swaying has come such a long way 🙂 Look forward to seeing where you are in another 2.5 years!

  77. Browning Lui says:

    what happen if you have to frame something very large for example like a 60" long?

  78. Darin Cates says:

    I made this today! Next, the picture frame jig!

  79. Myles Hurlburt says:

    I wasn't able to find your plans for this?

  80. JBratt says:

    I lke to make my keys a little tight and hammer them thinner.  They swell up later in the slot with the glue and time.

  81. ANuisanceRockBand says:

    A vertical slot cut in the vertical board would let you clamp through the jig and hold the frame in a more stable way, instead of at the top.

  82. Coquel says:

    You are the man

  83. Tom Zahlman says:

    This jig works great and very simple. Glad I didn't have to cut and fit runners like a normal sled.

  84. Turners Shed says:

    This literally made my day. Great simple jig 😁

  85. Angie Williams says:

    Last week I made a spline jib. I wish I had remembered this one and made one like this. The one I made was fine and worked. But this makes setting the blade height easier.

  86. Willem Kossen says:

    I revisit this vid as im now actually going to need the jig. I wonder how many views and comments you get on the older vids. This one popped up on top on youtube search on spline jig.

    Will this work for really big picture frames, like 70x60cm (sorry, i dont do inches)? Or do i need a bigger jig?

  87. Michael Box says:

    Does the drafting triangle need to be a certain size? All I can find locally is a 5in.

  88. Kit SUiam says:

    U can make a handle on the top of the jig…..looks nice and a place to grab back n forth the jig…..jus a suggestion ….anyway nice jig …✌👍👍👍👍

  89. TeknixTrix says:

    I was going to use a biscuit joiner but this idea gives a larger gluing area and I like the way the jig does a better job of alignment. Thanks for the inspiration.

  90. Crackerjack says:

    Very nice!

  91. Mrwolf4day says:

    What about jig for clue-ing

  92. Jason Heisey says:

    I just built one today, and it works amazing. I had to build it for an old Delta table saw, and notch out the housing over the guide bar because of screws on the back side of the guide, but that helped it to keep it more aligned.

    I left my frame guides a little longer beyond the jig for 2 reasons: 1) to support a larger frame, and 2) I can use the back one for a handle to push the jig through.

    Thanks again, this is great. Love your tutorials!

  93. Speedygoodyear says:

    Really good jig to have

  94. Ken Singh says:

    Mate, it's AWESOME!

  95. ekimusman2 says:

    what's the difference between your SS fence and the one that came with my PCS? i've never seen that SS fence before

  96. Robert Brunston says:

    Very good! I like it! Thanks.

  97. Nathan Terepocki says:

    I appreciate you! Whipped up mine super fast just now after watching

  98. Isaac Zeitoun says:

    Hi Dave. That's awesome and definitely the best I've seen. Where can I find the cut list? Would really appreciate it.

  99. Shane Stephens says:

    how long is the piece that is on the table saw guide
