I'd like to preface my response by first saying that I am fairly green when it comes to woodworking. I haven't built much outside of jigs and other things that I needed but couldn't afford for my shop. I have a two year old, and am only working part time "on the clock", so I am about as poor as poor gets. Having said that, I will say that I can empathize with every single one of your frustrations. Having to purchase sub-par tools is a fact of life for the inexperienced would-be woodworker living well below the poverty line. Harbor freight has been my best friend(I know, I know) through the initial setup process, with Craigslist coming in a close second. I have learned more in the past 3 months about machinery than I did in the previous 30+ yrs of dicking around. Likewise for measuring, cutting, budgeting and anger management. I have a lot of firewood outside of my shop right now. Really nicely dimensioned firewood. Some of it is from user error, some of it from impatience, and some of it from rage. None of it can be directly attributed to shortcomings of my equipment(yet). Use free wood for as many projects as possible. Pick up broken furniture from the free section on Craigslist and fix it. Why? Because you can. Leave the press board garbage for the waste management company, but anything that is made of real wood should come home with you. If you can't fix it, break it down into it's component parts and repurpose them. Salvage all hardware(even ****ty hardware) for a rainy day. Why? Because we're really poor, remember? Make your measurements as best you can, and make them relative to one another for now, so at the time of dry fit, while everything may not be square to a machinists standards, the parts will fit together(mostly). Remember to have fun. If you're not having fun, sell your gear and find a new hobby. Do what you can with what you've got, hustle hard to get more, and better, and treasure all of the lessons that these hard times teach us. I hate to sound like a Dickens-Ian motivational speaker, but real skills and beauty tend to be forged in the fires of real adversity. Keep your head up, and keep plugging away. It'll get better. It always does.
