Router Safety Tips:

  • Always wear eye and ear protection.
  • Always use properly sharpened bits.
  • Never use bits that are dull or damaged.
  • Shank must be completely inserted into collet and then backed-off approximately 1/16".
  • Don't "bottom-out" bit in collet.
  • Never partially insert bit into collet. Minimum 1" of shank needs to be in collet.
  • Tighten bit securely and recheck periodically for possible slippage or "run-out" due to wear.
  • Keep collet clean and replace if worn.
  • Never start the router with the bit in contact with wood.
  • Always feed your work or router in the proper direction against the bit rotation.
  • Don't force feed the bit or overload your router, Feed at a constant moving speed to avoid burning the wood.
  • Do not face tool's discharge when operating.
  • Always unplug router when changing bits or making adjustments.
  • Use a router table and fence whenever possible.
  • Make sure your work piece is properly secured and use push blocks, sticks and featherboards whenever possible.
  • Keep all your bits, bearings and assemblies clean, lubricated, and securely fastened. To avoid damage, store them properly in a pouch, box or tray.
  • The bigger the bit, the lower RPM recommended (see chart).

I have been building electric guitars for several years now, and tearout from routing perimeter curves has plagued me for years. The amount of extra caution needed to route properly with a straight flute bit was a hassle. With the use of these Spiral Upcut bits, a router table, and template, I am able to route 1 3/4" guitar bodies and 1" thick rock maple effortlessly. The time saving, and smooth cut makes the expense of these bits neglible. Every luthier should try one.
