Adhesives in Woodworking: Tips for Finger Jointing

From the weekend woodworker to the experienced industrial wood manufacturer…. whether you make furniture, cabinets, windows or doors, we know how important it is that your finished results are attractive and strong enough to be enjoyed for daily use.

When two pieces of wood are cut in a rectangular pattern complementary of each other so that the joint is glued and interlocks,

that is a finger joint. It is a simpler less-famous cousin to the dovetail joint, but still it is a useful technique that will add durability and style to your project.

To achieve excellent finger jointing, you’ll need to consider several factors, which include:

  • Adhesive selection
  • Wood and adhesive temperatures
  • Wood type
  • Tightness of joint
  • Adhesive application
  • Squeeze pressure
  • Handling of stock
  • Storage

Regarding the TIGHTNESS OF THE JOINT in the attached article, we at Shopsmith believe that the fit of the finger joint can just barely slip together with hand pressure, again with no gaps when dry fit, before final assembly. Today’s woodworking glue has good gap filling qualities and the glue will be strong enough to hold finger joints that slip together with hand pressure.

With that note, clarifying the different tolerance requirements of industrial//high production wood working industry from the more-realistic needs of the home wood-worker, the folks over at rsindustrial.com have put together this infographic filled with helpful tips on finger jointing:
