I really want to design and build my own pinball machine. I've re-themed, rewired, and rebuilt a baby pacman pinball playfield in the small mudroom of my house, but my parents have made it clear that I need to have my own workshop before I start on my next, more ambitious (and expensive) pinball project.
In an ideal world I would have unlimited money, time, and resources to make my own perfect homebrew workshop, but that is sadly not the case. I'm fifteen, still in high school, so both money and time can be hard to come by.
I have considered trying to build a workshop myself since it's usually cheaper than buying a pre-built one, and I have an employee discount at my local hardware store. That being said, I lack expertise in general building, and building it myself will inevitably be a long learning process, that may not produce good results.
I have also considered pre-built sheds, which, although more expensive, will be quicker and pretty much guarantee me a good structure, which I can improve upon later.
My main point is I want to build a (relatively) economical workshop, but I also want to have enough space to work and have room for equipment.
How small of a workshop is typically viable? 8x16? 12x12? Is pre-built the way to go if I have no prior experience?
Any advice is much appreciated!
