Woodworking is the process of building, making or carving something using wood.
2.Materials
Historically, woodworkers relied upon the woods native to their region, until transportation and trade innovations made more exotic woods available to the craftsman. Woods can be sorted into three basic types, Hardwoods, typified by tight grain and often derived from deciduous trees, softwoods, typically from evergreen trees, and man-made materials, such as plywood and MDF.
I printed spreadsheet charts like this to hang behind my lathe and
mill, showing the RPM for each belt position and the resulting cutting
speed for common diameters.
If I want to drill a 12mm hole in hot-rolled, for example, I look in
the 0.500" row for the highest pulley setting under 80-100 Feet per
Minute. Any comments?
---------------------
If you can find a drill press with power down feed, you will find that it
gives better results and drill life. Especially if you have to go to 1/2" or
larger in 303.
Woodworking drills often seem to have table mountings that are lighter than is
desirable. I have a woodworking drill (12", open slot, round table, 3"
pillar) and a metalworking drill (12", closed T slot, square table, 2 1/2"
pillar) and it's quite worrying how much the lighter table on the woodworking
drill moves when you lean into a 1/2" or larger drill in steel. Having said
that, the woodworking drill is where I can use it easily and the other drill
doesn't get used very often :-)
If the motor struggles with the monthly metal jobs, don't forget that a pilot
hole, about the diameter of the main drill's web, will make the main drill cut
far more easily.
