Found a game changer for squaring up cabinets on site
I used to just rely on my speed square and eyeballing it for box assembly, but after 5 kitchen jobs I noticed I was fighting doors that wouldn't close right. Switched to using a simple 1/2 inch plywood squaring jig I knocked together in 20 minutes, and it cut my adjustment time by about 45 minutes per job. The difference was night and day after the first 3 cabinets I clamped it onto. Anyone else got a homemade jig that saved their back and their sanity?
