10 - Heavy Duty Lathe Stand, страница 23TECHNIQUE MEASURING TIP Using a rule to get an accurate measurement on a workpiece can be tricky. The problem is getting the end of the rale to align exactly with the edge of the workpiece. To solve this, I use a stop block, see Drawing. Just hold a scrap of wood up against the workpiece. Then push the rale against the block for an accurate measurement. PARALLEL LINES To quickly draw a line (or lines) parallel to the edge of a board, I use a combination square and a pencil, see Drawing. Start by setting the square to the desired distance. Then position the head of the square against the board. Now with a pencil at the end of the blade, pull both toward you to draw the line. FIRST: HOLD STOP BLOCK AGAINST WORKPIECE SECOND: PUSH RULE UP AGAINST STOP BLOCK Measuring Inside DimensionsSCRAP BLOCK Measuring the inside of a drawer or a box can be a problem since the blade of a tape measure doesn't fit in a corner, see Detail. One solution is to use a block and a tape measure, see Drawing. Use the tape to measure from the opposite side to the edge of the block, then add the length of the block to this measurement. MEASURING STICKS Another solution to finding an inside dimension is to use "measuring sticks," see Drawing. They're just scrap sticks with pointed ends. To use them, just slip the sticks inside the box or drawer and extend the ends until the points touch the workpiece. Then clamp the sticks together and lift them out. Now simply measure from point to point. USE TAPE TO MEASURE FROM OPPOSITE SIDE TO BLOCK THEN ADD MEASUREMENT TO LENGTH OF BLOCK EXTEND STICKS TO FIND INSIDE DIMENSION AND CLAMP No. 10 ShopNotes 23 |
