Clifton 770 Plane Review By: I.Ball
Category: New Bullnose Planes
Manufacturer: Thomas Flinn & Co
Plane Type: Bullnose
Model No: 770
This Clifton bullnose plane review is of the current Clifton 770 plane manufactured
by Thomas Flinn & Co, Sheffield, England.
The plane had previously been made by a tool company called Clico (Sheffield) Tooling Ltd until 2014 when Thomas Flinn and Co took on the Clifton tools part of the business.
The Thomas Flinn version of the 770 is made in almost identical circumstances to the Clico version including being made by the same skilled personnel:
"We will still be using the same great production staff to manufacture the Clifton planes, so the knowledge and expertise will continue as before".
Please see the old Clifton 770 plane review for more information about the Clico (Sheffield) Tooling Ltd Clifton bull-nose plane number 770 (virtually identical other than the blade type and the box).
The Clifton 770 is a 4" (102mm) adjustable,
fixed nose bull-nose rebate plane.
The one-piece plane body is constructed from quality grey cast iron with the sides and sole being precision ground.
The 770 can be used left or right handed and can be laid perfectly flat and used on either of its sides to trim rebates, shoulder lines and tenons.
The plane has curved areas on top of the plane and finger imprints on the plane sides offering added comfort and control.
The Clifton 770 bull-nose plane is equipped with a blade adjusting mechanism. The blade adjuster control is located at the rear of the plane in the form of a knurled nut. The adjuster is used to control the depth at which the blade will cut.
The plane is fitted with a shouldered cryogenically treated O1 steel Clifton 770 plane blade. The cutting edge is 1 1/8" (290mm) wide with a bevel edge. The top of the blade has a slot to allow the blade adjuster to locate with the blade. The blade sits in the plane with the bevel edge side facing upwards.
The blade is held firmly in place with the use of the securing cap / lever cap.
The cap locks the blade in place by locating the securing cap into the two notches
in the plane body and then turning until tight the knurled securing wheel located
on the underside of the securing cap. The securing cap is constructed with unbreakable
The plane is presented in a brown cardboard box with the Clifton logo.
The Clifton 770 bullnose plane is a modification of two similar planes produced in the first half of the 20th century:
The Edward Preston bullnose plane 1355, was produced in the first 30 years of the 20th century.
The Record 077 bullnose plane, was produced by Record in the 1930's.
