In relating to the above posting, this drawing is meant to represent the roof, wall and floor of a house. The rectangle is to be a 2x4. Arrow #2 denotes the intention to move the 2x4 to the left until it is snug with the floor and roof and can be used as a stud in an interior wall. The arrow labeled #1 denotes a cut to be made in the top of the 2x4 so that it will be cut at the same angle as the roof. I would like to know what method people would propose of getting the right/most accurate line drawing on the side the of 2x4 before it goes to the saw. Thanks, SD

  • I like to cut the piece a little longer, then I can trace the angle in place, and cut it perfectly. Especially on an old house, where every one is going to be different.

  • Arrows!!!

  • I guess where I'm stuck is how do you get the stud held up and be able to trace the right angle? In the past I've held a chunk of scrap against the ceiling,then put the stud along side the chunk so that the correct angle is telegraphed out from the wall and I can hold the stud vertical and trace along it without the corner to be cut off getting the way. But how do I do that and still have the stud be long enough be flush with the floor?

  • Geometry! Whoo hoo! (This is where my geeky engineering undergraduate degree raises its nerdy head.)

    Do you have a protractor? And a level? You can set the bottom of the protractor against the slope of the roof (use it upside down). And use the level vertically to find the angle (the level will represent where the stud goes. Make a paper pattern or experiment with a piece of scrap wood to find the perfect angle setting on the miter saw or box that corresponds with you measuement. Voila!

    There is probably an even easier way, but that is my cheap, geeky technique :)

  • You can see a geeky online flash protractor here

  • Here's another helpful link for measuring an angle with a protractor. Just remember...when you are measuring the roof angle, you will be using the protractor upside down and your angle will be between 1 degree and 90 degrees.

  • You need a carpenter's sliding bevel. About $5. Here's one at Amazon.

    For your application, place a level where the stud will go and hold it vertical. Use the bevel to copy the angle between the level and the roof truss, then place the bevel against your 2x4 and copy the angle.

    You can also use the bevel to transfer the angle directly to your new saw. Place the bevel on the saw's fence, and adjust the blade against the other side of the bevel.

  • Carpenter's sliding bevel... I like it. I could probably even get away with making one with a wing nut, bolt some washers and sticks, no?

    I think I get the protractor technique...

    To measure the vertical length of the stud, should I use a tape measure and level, running from truss to the 2x4 that runs across the floor or should I use a plumb bob instead?

  • Duh, you use a nice elm wand, wave it a couple times and say studis correctoangleii! Jeez. Duh.
