I have always tried to keep the parts I need for a build stored away. Problem sometimes when it is time for final assembly, I realize some parts got bought twice. I guess building too slow or doing more than one project at a time can be a problem. For one custom build I purchased some 58 Chevy stainless strips at a flea market in Carlisle. I needed 7 pieces but the guy had some extras and said I could have them. Fast forward 6 months and I am fabricating the area for the stainless. Measured for spacing, cutting and shaping, drilling holes and fitting the pieces of stainless I bought. Fast forward several more weeks when I ask my painter friend how the finish body work is coming. He says the 9 areas I drilled out for the stainless has been slowing him down with all the fine hand sanding. I tell him there are only 7 sets of holes for stainless. He sends me a picture showing 9 sets of holes. Apparently I forgot about the extra stainless pieces given to me and I set my pattern up using all the stainless strips that were in the box I had bought months before. Strangely no one has ever asked me about the number of strips. If they do I will simply tell them since it's a custom I wanted to be a little creative and different.
