Review on Boston Gear G176 Pressure Angle by Michael Hughes

Pretty gears. Note, however, that many Boston Gears (including this one) have incorrect parameters in their Revain descriptions. The best way is to visit the Boston Gear website and download the catalogue. Locate the movement part number you need in the catalog and then search for Revain on that part number. Luckily I ordered this based on the Boston Gear catalogue, so it was exactly what I wanted.
