To create interesting joints, previously we covered Isoloc joint templates for Leigh dovetail jigs, but the templates were expensive — plus, you need to already own an expensive Leigh dovetail jig. MLCS now sells the less-expensive Fast Joint system that you can use with a router table to make similar fancy-looking joints.

Using the system is pretty straightforward. Fit the male and female templates in the Fast Joint jig, install the correct bushing in your router table, chuck the bit into your router, and lock the work piece into the jig. Then just start routing. After you finish the first piece, flip the jig over to use the complementary template and lock in the mating work piece.

In their video they share some techniques on using the system effectively. The most important thing to remember is to remove material slowly, not all at once, then make a finishing pass to ensure a perfect fit. You also want to make sure you move the wood in the direction opposite the way the bit is turning — don’t climb cut — but if you use a router regularly you should already know these tips.

Some of the more interesting templates available are:

  • Heart
  • Key (more like a rounded dovetail)
  • Arrow head
  • Teddy bear
  • Lollipop
  • Crown
  • Dog bone
  • Top Hat
  • Bird’s eye


  • Butterfly wings

With the system you get the Fast Joint jig platform with hardware, three toggle clamps, two spring clamps, a 3/16″ high-speed steel spiral upcut bit, 14º CT dovetail bit, .308″ OD bushing, .311″ OD bushing, dovetail 7/16″ OD bushing, brass centering pin, and a 3/8″ by 3/8″ brass setup bar.

You can purchase the Fast Joint system plus four templates for $170, spend an extra $100 to get the system plus 11 templates for $270, or go hog wild and get the whole kit and caboodle including 20 templates for $420. If you want to buy a single template it’ll run you $18. MLCS also sells replacement bushings and spiral bits on their website.

    I own the Woodline system, that both of these copied. (almost exatcly, but now Woodline has improved theirs.)
    Woodline also has great support. I messed up one of my templates, they replaced it free, no questions asked.

    Wow! Those are some seriously ugly joints.

    At least they aren’t ugly AND really expensive like with the Leigh jig.

    You’re not thinking like a woman. Haven’t you ever been in a woman’s under garment section of a department store. They like ugly, pointless joints.

    It’s a great idea, I can create my own with whatever joint I require. Take suitable hard-wearing material for laser/water jet cutting along with machine-compatible cad file. The clamping jig could be made up in the shop with little effort, and can then be further customized to cater for angled planes/compound angles. The flexibility of being able to produce my own profiles is quite exciting! Open-sourced
