It is near impossible to learn how to do carpentry from either books or the Internet. I know because I’ve tried really hard.
Let’s say you decide you no longer want to buy bookcases from Ikea but you want to make you own. You decide a book case is simply a box and decide you want to learn how to make a box with a few tools and some simple instructions.
If you go search for help with your box, you may very likely come across instructions like this: www.popularmechanics.com/home/how-to-plans/how-to/g1591/how-to-make-a-box/
It makes assumptions that you have lots of tools and you can do hard things like cut joints. After a few hours of searches, you will find most sites are like this: tailored to woodworkers making wood pieces that are hard to do and not anything near modern looking.
IT is different. For any technology out there, you can search for the name of the technology and “tutorial” and find something. You can be up and running using the technology in the time it takes you to give up looking for carpentry skills.
I am not sure why that is. Maybe there is more interest in IT so there are more tutorials on it. You could argue carpentry is harder but I have done both and I disagree.
I especially disagree because there is one site I could that actually does make it easy to make furniture and that is Ana White’s. Because of her I have made a wide range of furniture with basically a hammer, a jigsaw and a drill. The furniture isn’t fancy but it was cheaper and better and as modern looking as Ikea.
I think that is a problem with a lot of woodworking sites. They assume you want to do fine woodworking. Find woodworking is fine, but for people starting out, they likely want to make a simple table, a bookcase or set of shelves, perhaps a storage chest. A good joint may be best, but most Ikea furniture is held together with dowels and screws. If you make a book case with dowels and screws and glue, it will last and hold lots of books.
I wish there were more introductory sites on the internet that help people who wanted to learn how to make furniture and do carpentry, like there is with IT. Right now all I have found is Ana White’s site. I highly recommend it.
