It was good. Reminds me of something you would do RC.

This isn't really nerdy enough, but my furnace motor died. The "technician" (they don't call them repairmen anymore) recommended I replace the whole 20 yr old furnace but said he could try and find a replacement motor. Long story short, he "found" a new replacement motor and the furnace works great. Furnaces and hot water heaters sure do not last like they used to and are becoming as disposable as modern dishwashers.
