Make: Online regular Craig Smith wrote in with a clever fix for his durable no-name electric drill:

Six years ago I bought a cheap off brand cordless drill for work. My namebrand loving co-workers give me grief for it, but it does the job year after year at a fraction of the price. These are people who think the tools make the tech, and not the craftsmanship and skill in the workman. After recently buying new replacement ni-cad battery packs for it, the electric motor smoked and died. Since I have a reputation for keeping the oldest of equipment humming along, I jokingly took it home to fix it. Darned if I found an exact replacement motor in my storage tote of motors that I collected over the years. The problem was the gear was pressed on the shaft so tight it wouldn’t budge with a pair of screwdrivers harmonically prying it. So with some micro spot-welding on some nuts & bolts, in 20 minutes I made a gear puller. I’ll show up for work with the old drill ready for another six years of duty. And I’ll have to toss them the gear puller to reinforce craftsmanship.
