Paying rent on build space is great incentive to experiment with ways to improve productivity - anything that looks like a useful tool is probably worth buying if it's not too expensive. I spent some time browsing other builders' comments and made a list of useful items to have. I probably ended up wasting money on shipping costs by buying from so many vendors, but there were so many odd items to buy I really didn't have much choice. Hopefully this stuff will all end up being useful. The only items I believe I'm still missing at this point are some items related to specific steps in specific chapters. For instance, I may need a few extra drill bits for specific steps. I'll purchase those with the steps they relate to.
