Overarm Pin RouterOverarm Pin Router - Information

ust mount the Overarm and Router Table directly to your MARK V's twin Way Tubes and Worktable and in minutes, you'll be performing many operations faster and with far greater precision and repeatability than you could ever hope to achieve with conventional routing methods.

You'll do all this with your overarm Router:

  • Form decorative edges and surface designs on straight or curved stock.
  • Cut precision dadoes, rabbets, sliding dovetails, drop-leaves and similar joints.
  • Repair furniture and veneers.
  • Joint workpiece edges for glue-ups.
  • "Saw" straight and irregular shapes.
  • "Drill" round or oddly-shaped holes.
  • Pin rout exact duplicate workpieces.

And, since it operates with the bit cutting down from above the workpiece, you'll have a clear, safe view of your work at all tiems...and be able to make depth-of-cut adjustments with a simple drill press-like quill lever.

So...what exactly is Pin Routing?
It's a simple operation that uses a shop-built guiding fixture to make exact duplicates of workpieces, just like they've done in cabinet shops and furniture factories for years.

Overarm Pin Router

Here's how the Pin Routing process works:

  • A particleboard or MDF ficture is made by cutting grooves in one side, matching the shape of the pieces you want to make.
  • A straight bit is inserted into the router motor (mounted in the Overarm).
  • A tracing pin (same size as the groove in your fixture - and your bit) is inserted into the Table Plate. The pin and bit are then aligned perfectly with one another.
  • A workpiece is temporarly screwed to (or clamped into) the opposite side of the grooved fixture.
  • The fixture is then flipped over (with the workpiece attached) and its groove dropped over the tracing pin.
  • The router motor is turned on and the bit lowered into the stock. The groove is traced over the pin, creating a workpiece that matches the size and shape of the groove in your fixture, perfectly.
  • The workpiece is remvoed and replaced with a new blank...then the process is repeated, if desired.
  • Once you've made a fixture, cut out as many parts as you like, then set it aside until the next time you want to make more of the same item.
