Today, I joked with my older brother than retirement allowed more time for seeking out spare parts. The 1.5 year old oven broiler had a problem. The manual drawing by Maytag was incomplete. Three trips to the appliance repair store and I may have fixed the broiler seal. The email help from East India online was no help at all. Starting one month ago, I visited my official Stihl store for chainsaw parts. Multiple visits. No, the air filter replacement has not come in for 30 days. There was no ability to make a chain two weeks ago because the "tee" part was not in inventory. Imagine a chainsaw dealer not having the parts! I gave up on the official dealer in the local community and sent an email to another official dealer nearby to learn if it is stocking parts. A few years ago, I visited a brilliant gunsmith. He had all kinds of equipment, but very limited spare parts - and he worked on only a few models of firearms. He would order parts by mail and wait weeks for them to come in. It was an American professor who purportedly taught the concept of "just in time inventorying" made famous in the Japanese auto industry. Now that model is used all over the world. When you combine that concept with big box hardware stores, you have a potential problem in getting spare parts. I try to deal with the problem of spare parts (largely the cars) by researching the maintenance manuals and buying ahead. If I end up with parts at the end of the car's life cycle, I simply give them to my reliable auto mechanic and he gives me some money or free servicing. This is just a reminder that if it is hard to obtain spare parts in a modern economy, it is going to be considerably more difficult when shtf.
