  • This week I’m building a simple spline jig. Plans are available on my website almfab.com/plans
    This jig can be built in less than an hour with plywood scraps and works on any table saw or router with a fence. Splines reenforce miter joints and they look good too. I use them in my shop on picture frames and decorative boxes.
    Big thanks to long time supporter of my channel, Rockler!

    It seems that the evolution of all woodworking/maker CZcamsrs is to have a Dewalt contractor's saw, then later to get a SawStop. You've done it, Tamar and Wesley Treat both did the same.

  • @xeren45

    Just built the jig from the plans and I have one suggestion!
    For people using this with a router table I would recommend using 1/4" plywood as the base instead of 1/2" plywood, as routers can't reach up as high as a table saw blade.
    I had to extend my router bit up from the collet higher than normal and got some predictable chatter as a result. I ended up using a mortising bit to take a quarter inch off of the bottom of the jig (and used a 1/4" piece of plywood to stabilize it as I got more than halfway done) and now it works perfectly!

    The Murphy Bar! That's a blast from the past.
    I scored an offcut of Bolivian rosewood still coated in wax from the bin at the Northgate Rockler about a year ago. I've been meaning to make a splined vanity tray and figured the rosewood would be an excellent contrast with maple. This jig just spurred me into a project for tomorrow. Thanks for that, and excellent work as always.
    BTW, I have one of those DeWalt jobsite saws as my only table saw. I live in a condo, so as much as I'd love a nice cabinet saw, I have to make do with what will work on my patio. It does the job, but finding good blades in 8 or 8-1/4 can be a bit of a pain. I make it work, though.

  • @CubeTricks
    @CubeTricks Před rokem +2

    I just finished building this jig, and I am really excited to use it. I did have have one issue where two of the screws broke off when trying to remove them, luckily both on the same side so I should be fine as long as I don’t pass the whole jig through the saw, but I wish I had thought to wax the screws before the glue up to keep them from sticking after the glue dried. I may try to core the screws out eventually or just rebuild the jig later as I plan to make frames frequently.

    • @rodc4334
      @rodc4334 Před rokem

      Just a suggestion. Mark very prominently on the box with a sharpie or something were the screws are where you will see them so you don't forget. I know sooner or later I would forget. Or if close enough to the edges, just rip to make the jig narrower and minus the screws.

    I work with a Bosch GTS10J, almost like that table saw of yours and I had a kickback, few weeks ago, doing exactly spline cuts, but the other way around. As I don´t have an affordable Rockler´s stuff access here in Brazil, I´ll have to build a jig like that. Thanks for that tip.
    And by the way, I love your plywood pattern works. Trying a few here.

  • @dankinsky9543
    @dankinsky9543 Před 9 měsíci +1

    I used your plans and worked great but one suggestion is to add removable 1/4" plywood to your jig. Having the spline cut with a 'zero clearance' at the exit
    is really imprtant when using a dado BUT where I screwed up was not allowing for a smaller spline after initially cutting at 1/2" wide. My next project using 1/8" splines had a lot of tear out so I added cheap scrap plywood 'faces' to the jig and now have a 'plate' I can remove and add a new one if I have a new width of spline. I also like your 'sandpaper' table! Can't believe I never thought of that!!!

    Do you use a thin kerf blade when ripping your splines, if so how many teeth, and what brand?

    Another great video! Thanks, Michael. As I saw you make the cuts, I couldn't help but think that there's a good chance for this jig to kick back especially if you're taking out the workpiece, flipping it, etc. Have you had any close calls? Any thoughts on a design that would accommodate an accidental bump or wobble?

    Great video and jig. I have a question about using it over time. How chewed up does the bottom get with many cuts in different places? As the slots widen do you begin to experience tear out? (I’m building it regardless because it’s a great looking jig. And it’d be easy enough to build another later.)

    Wouldn't it be better to make the jig wider so that it can fit along one of the rails of your table saw. The way that you've made yours I'm assuming you'd have to make another jig after a while because you put so many spline holes in it, am I correct?

I am looking for the best finish to keep the natural look and make the colors Pop. Anyway I could send you a photo I really want to do the best finish and I have tried a few things on scrap and I’m not happy like polyurethane oil based and it doesn’t look good? I need your help I’m 60 hours into this table and I’m stuck on finish. Thanks

    What is the measurments of the kerf on the saw? The biggest size I can purchase (here in the UK) comes in at 2.8mm, and it produces a very thin gap for the mitre bits. Using a Biscuit Jointer seems to create a more pleasing mitre insert.

    • @MichaelAlm
      @MichaelAlm  Před 3 lety

      It served me well for 5 years. My biggest complaint is that it only had a 20" rip capacity, and the infeed support is too short. I think they've increased the rip capacity now, and you can build both infeed and outfeed support into your workbench. (which I highly recommend) Great tool for the price.

    • @jimblackwood1693
      @jimblackwood1693 Před 3 lety +1

      I’ve had the Dewalt for a couple of years. It has been a reliable saw and has been worth every penny I paid for it. I would second that the indeed/outfeed distance is pretty short. I have an outfeed/assembly table but because of the way the fence rides on a geared track and because the power, depth and angle adjustments are in the front I haven’t been able to come up with a good indeed attachment that has access to the power and height adjustment. I made a cart for it that has extra width on both sides to help support wider boards. The only other negative I have is the noise (which applies to all job site saws). It is way louder than a cabinet saw because of the type of motor and because the motor is exposed.

      Sorry about that! Send me an email thru my website and I’ll get it sorted. www.almfab.com/about

    Nice again. :-)
    I have been wondering so long, so I will simply ask now: are your ancestors on your fathers side from Austria or the south of today's Germany? In Austria, the family name ALM is found quite often in the country mountaineous area of Salzburg, Kärnten and Steiermark. Also, many Austrians from these regions moved mainly to the United States, when they were Protestants fleeing from the Catholics in their homelands. Just wondering.... ;-)

      Interesting. As far as I know my last name is Swedish. It means Elm tree.

      @@MichaelAlm Oh yes, that's right. In German Alm means alpine pasture. which is why most of the people with the name ALM have ancestors, who were alpine farmers. Nowadays, there are only a few alpine farmers left, as this work is extremely hard and even today incomparable with historical farmers in the valleys.

    Why didn’t you end up using a runner?

      Because you have to move it left and right to set up the slot. Besides, the table saw fence does the work, so It's not necessary.

    Why does this add strength? There can’t be that much grain in that corner? The grain runs out on the corner just like the miter from the main piece. I do like the look tho

      A miter joint is weak because it glues end grain to end grain. Wood glue doesn’t bond well to end grain. A spline bridges the gap between the joint with a long grain connection with a lot of added surface area. It adds a surprising amount of strength.

    Warning: Timestamp 4:53 -- Pause at this timestamp please. Note: Michael stated earlier in the video that he would remove the screws at the bottom of this jig. Also, Michael comments that the pin-nails he is using in this shot are only placed higher up on the jig so that they will not come into contact with the blade. My point is this, "This is serious!", "Pay attention!" "NO METAL SHOULD BE USED IN ANY PROJECT CUT ON A TABLE SAW AS A GENERAL RULE, BUT ESPECIALLY IF YOU HAVE SAW-STOP TECHNOLOGY IN YOUR TABLE SAW." If you hit metal with my table saw it will trigger the Saw-Stop system and cost $170 to get the saw operational again. FYI plastic nails, and plastic pin nails exist and would have been a better choice for this build. Also Note: There are super sensitive Saw-Stop sensors that can get trigged by wet wood glue. WTF! Let your glue dry. Don't be the dork that shuts down the workshop. Remember, as a last resort... you can always blame the New Guy. : )
