I'm deep into my 51 Ford Coupe right now. I realize how easy it is to waste money or spend too much on stuff that's never used. It's real easy to spend money on fixes that never work out. It's real easy to get tools that you'll never use. Most aggravating is buying hardware putting it away. When it comes time...it's lost and you buy it again only to find the lost pieces when you are finished. A project that is a wandering zero as far as direction, can bleed money. Sometimes doing stuff "on the cheap" winds up costing more. I'm not meaning substandard repairs, rather good quality stuff that in the end, you don't use or change direction. Buying used parts because "it's too good to pass up" or a "good deal " and you never use them. Another hidden cost is time and gas. It's real easy to shop at the parts store and buy stuff you really do not need or think you need but don't. Blowing money on substandard parts....this is especially true with wiring components such as splices, the splice kits and crimp on wire ends. You can use some of that stuff but to use it properly, it has to be modified. A good example are those cheap blue crimp on connectors and splices. I was asked why am I using a expensive replacement wiring harness rather than a universal kit or making it my self..... This harness is already done...all the connections. All the splices. Even the main body of the harness is wrapped in friction tape. It's pretty much ready to install. I know if I tried to make that I would blow a lot of money. It was worth it to me just to spend a little more up front than nickel and dime it. Sometimes I find nickel and diming can cost more. This is especially so if you wind up getting the expensive part anyway. Parts... I need some parts right now. I'm going to order what I need from a Specialty Supplier, this time CG Ford. I'm going to order all I need for this task. It's a little more and there is shipping but I feel it's cheaper than the multiple trips tp local parts store. One.... I have to research and find that they have the part. Two...I have to drive to town go in and ask for the part and they have to look it up. Three....If they can get the part...sometimes their websight lies, I order it. Four....I go to get those parts....only some have come in so...that's another trip. Five...Impulse buys at the parts store. Ooooh! Shiny! I need that. Personally It's best for me not to get too far ahead. How do you try to avoid the waste?
