For the past four weekends I have helped my father in law build a shop in his backyard. It ended up being a much bigger project than we thought. All he wanted was a small garden shed but we ended up making it into a 14×14 shop, complete with peaked roof,  shingles, and hardi plank siding. From the experience I now know how to construct a building all the way from the pier blocks for the foundation to the peak caps on the roof. I am now a skilled door and window framer as well as a siding specialist. Just today I also fixed our hot tub. We have not used it for a few months because the lid broke. We recently refilled it and the breaker kept tripping. I did some research on the internet and found out that the heater element must have failed. I took apart all the electrical components and replaced the element. So after that repair I am now an electrican and a hot tub repairman.
