    on that same subject...

    [u]Kyle.w</u> brought up a good question for us novices about the throat length of scroll saws. I finally figured that "inch" designation out after researching some band saw info but was wondering if it applied to drill presses as well? A 9" drill press has a 9" throat depth, and so on - am I getting it right? Along those lines, anyone find a DP throat depth greater than 12" useful for occasional hobby and amateur use?

      The throat depth on a DP is measured in terms of the "swing" in inches....meaning how large a piece it will drill to the center of. An 8" DP has 4" of depth and will drill to the center of an 8" board. A friend of mine has a huge 465# Grizzly DP with a 46" swing, and yes it does come in handy sometimes.

          Actually it (the swing of 9") defines the twice the distance from the edge of the vertical support post to the center of the drill axis...

          Pretty much as dustmight defined it above.

          If you have a swing of 9" and a 1" drill bit then the edge of the hole to the edge of the board will be 4" (because the hole center is at 4.5" and the bit radius is .5".


          BTW that's in the BT3 FAQ, too.

              To confuse issues - 12 inch, 14 inch (etc.) bandsaws on the other hand are listed as the amount that is between the frame and blade, the maximum it can cut in a pass.

                  Actually that only applies to cuts on the left. Cuts on the right can be unlimited...

                  and table saws and miter saws are rated in the size of size of the blade they take, has nothing to do with crosscut size, depth of cut or rip width.

                  go figure, eh?

                          bandsaws are measured by their wheel size, which btw will give you the same measurement as their "max cut to the left"

                              OK, let me get this straight. A 12 inch drill press can drill 6 inches towards the center of a piece of material. so, if I had a 2 foot by 2 foot piece of plywood I could only drill into it roughly 6 inches on any side. Am I getting the concept?

                              Band saw, miter saw, and table saw specs are much easier to figure out by just shopping around and reading the tech info...

                                  that's exactly right.
                                  There's roughly 1 ft x 1 ft are in the middle you'd have to use a hand drill for. But its not so bad as it sounds.

                                  in plywood its not so important to drill straight vertical because it's only ~1/2 inch thick.

                                  The drill press real value comes in thicker pieces where vertical, straight, parallel holes make for a nice project. This starts in piece of 1x, 2x and 4x materials, most of which don't exceed 12 inches across.

                                  Not to shortchange the DP - a Drill press also offers the ability to use a table and fence/stops to precisely repeat positions plus depth stop to get precisely the same depth holes.

                                      Yup - it's definately on my list of tools to get. I've had a number of projects in the past that needed a DP - especially when needing to use forstner and spade bits on them.
