  • How to drill perfectly placed hole into outside corner

    Trying to drill into a outside 90 degree corner, 45 to each side, is tough, the drill bit keeps wanting to walk off.
    You can whack a small flat on the corner.
    But here is a way I did it perfectly. Using this corner drill jig

    Using the drilling jig, One hand is enough to hold the jig while drilling. The small board touching the top of the jig is my measurement stick. I use that to set the precise reproducible location of the hole relative to the top of the workpiece.

    I was able to attach this brace block to the inside. I prepared it by cutting off the tip and drilled a pilot hole in the tip on the drill press prior to assembly. The pilot hole location in the center of the brace and the precise location of the hole puts the brace at a precise location, too.

      by LCHIEN
      So you want to buy a BT3 clone. Been out of production for a while. Shopping on Craigs list or for sale ads is hard

      You have to keep an eye out and you have to be used to spotting the appearance giveaway features of the various models... Ryobi BT3000, BT3100, Craftsman 22811 and 21829
      There are certain things that clue you in and there are many ads that don't give model numbers and have crappy photos. Search for keywords RYOBI, Precision, System are often used in ad listings and

    • How to tell plunge router bits from non-plunge router bits.
      by LCHIEN
      Do you guys know your router bits?

      Do you know how to tell a plunge bit from a non-plunge bit?

      A non plunge bit has cutters around the periphery, but not the center. It can enter grooves from the side and cut moving sideways.

      A plunge bit has cutters that go all the way to the center of the bit face. It can cut moving vertically as well as sideways.
      Above see the bar across the center as well as the two edge cutters? Without this bar, when you drive the...

    • Festool Domino Settings for Evenly Spaced Mortises
      by twistsol
      I was in the shop this weekend and was trying to figure out the math for the settings on the Festool Domino to space the mortices evenly and centered across a cabinet front to back. After a bunch of trial and error with my math, I gave up and got close enough and cut the Domino slots for most of the cabinets before my shop time ran out. It was still bugging me, so I figured it out on the plane on the way to work.

      Very simply, we need to subtract the width of all mortises created from...

    • Sharpening Woodworking Chisels
      by Sam Conder
      While attending a "fundamentals of woodworking" class taught by Marc Adams at the Indianapolis woodworking show a few years ago, I was most impressed with his simple yet effective method of sharpening woodworking chisels. I contacted Marc and asked him for permission to write an article for BT3Central on how to sharpen chisels using his method. As expected, Marc was very receptive to the idea of sharing one of his "secrets". His exact response to me was " Absolutely, please feel free to teach anything you learned from me." So let's dive right into this and sharpen some chisels.

    • Primer on air fittings for the woodshop
      by LCHIEN
      Most common places to use air fittings in a home shop:
      Air compressor to hose or female QD fitting
      QD female fitting or male stud to hose
      male stud to tool (such as - air nozzle, nailer, screwdriver/drill/impact driver etc, spray painter)
      any semi-permanent 1/4" NPT to 1/4" NPT fitting

      To add to the confusion, there's nothing on a 1/4" NPT that really measures 1/4". THe threads are visibly tapered and the overall outside size of the male NPT...
