CLIFTON - #6 Fore Plane
The term 'Bench Plane' refers to the the range of planes originally made for and by Stanley/Bailey and with numerous versions, copies and clones made all over the world such that there are literally tens of millions of them in existence.
They look alike as a family and mostly vary only in scale. Most of the fasteners are standard across the range and, presumably to introduce a degree of proprietary control, often used an unusual thread standard e.g. 7/32-20 (7/32nds of an inch with 20 threads to the inch) for the knob screw.
In the UK Record and Clifton in their heyday made planes the equal of any made in the USA
They were manufactured in sizes #1 #2, #3, #4, #4-1/2, #5, 5-1/2, #6, #7 and #8.
A #1 was 5-1/2 inches (140mm) long and the #8 was 24 inches (609mm) long.
The term 'bedrock" refers to the period in and around WW2 when Stanley planes reached their best design and manufacturing standard.
The current Clifton offering can be seen as their gold standard with superb production values. Heirloom tools.
