A bench plane will flatten a surface to an accuracy equivalent to the depth of cut over the length of the sole. So the longer the plane, the greater the accuracy.
At 22" (over half a metre) long, the Clifton No.7 is big, solid, accurate plane designed for flattening surfaces and preparing the edges of boards that are to be joined together. The balance of the Clifton makes it much less unwieldy than you might imagine, indeed for some woodworkers the No.7 is their main handplane.
By no means limited to edge jointing, the No.7 try plane excels at flattening large surfaces, tabletops, bench tops, large panels etc.
Like all Clifton planes, the casting is ring tested and fully stress relieved before being pre-loaded and individually precision ground. British Standard tolerance for a bench plane is 3 thou (+0.0015"/-0.0015") so Clico work to a unilateral tolerance of -0.0015"/+0.000" in order to fall well within that range.
Every plane is tested for flatness with a 1.5 thou feeler gauge, against a granite bed and then against a 'grade A' (accurate to two ten thousandths of an inch per foot) straight edge in the centre of both the length and the width. If it passes, it goes on to be assembled, and then the finished plane goes through the whole process of flatness testing a second time before finally being signed off by the workshop manager as flat.
