1) Steve Ramsey (WoodWorking for Mere Mortals
) does a great job at helping beginners get up to speed. He sort of de-intimidates woodworking yet still articulates safety issues.
2) Watch videos that explain the physics woodworking.
Matthais Wandel has several that have helped me. Understanding what forces happen in which direction is immensely helpful to stay safe.
3) Go to IFTTT.com and set up some reliable Craigslist alerts for cheap routers!
The physics involved with high speed rotating cutters is very important to understand. Throwing apiece of wood against a 3600 RPM saw blade without knowing what to expect can be dangerous. Let alone the internal stresses within a piece of wood which are unknown until you make that cut. Then, having router bits spinning at 20,000 RPM and not knowing which direction to feed the work into them can have disasterous results. Ripping wood on a RAS without knowing that the work will tend to lift OFF the table is another common mistake made by beginning woodworkers and has given the RAS a bad reputation.
Proper wood preparation before using a table saw is vital to not only get good results, but to accomplish it safely. Twisted boards do not sit well on the table saw, either literally or figuratively. This is why there's a jointer in every professional and well equipped woodshop that uses powered machines. Jointers are NOT thickness planers and there's another source of confusion for beginners.
Everyone thinks they can make a mitered corner picture frame using the miter gauge on their tablesaw, only to find out the joints don't mate correctly. Precision cuts are necessary for even the most simple of operations and that requires knowing how to set up your equipment properly. You may need a special tool just for setting up your machine that is never used in making your woodworking project ... a dial indicator comes to mind, as does a digital angle indicator.
Experience using different species of wood gives you knowledge that you can apply when making a new project. How they look when stained, when clear coated, how they move across their width will all affect the look and even the performance of the finished piece.
Knowing which joints have the most strength against racking will give the piece added strength and make it last longer. Which glues to use and when to use them always comes up here. How much clamping pressure us required and how closley should the pieces mate before gulling them up are other commonly asked questions.
Do I need 220 Volt service in my shop? Countless questions on shop wiring deal with electrical issues. I probably have 10 220V outlets in my woodshop alone. The motors that require a 220 V servive are 3 HP or greater. There is no such thing as a 3 HP motor that runs on 120 Volts, regardless of the label on the side of the cabinet.
And speaking of wiring, if you can't see what you are doing, then you won't be safe or get good results. Get adequate lighting before anything else.
A solid, non-movable secure workbench is as much a safety item as it is a convenience. If your workpiece is jumping around while you are handplaning it, it won't be easy to work on OR be pretty afterwards. Sharp tools work better than dull ones, so learn how to make them sharp and keep them that way, especially handplanes and chisels. There are You Tube videos on the process and the various types of stones used for each one.
There Ya go, that will get you thinkin'
