The A27 Bullnose Infill Plane.
This plane was traditionally a casting and not dovetailed, although I have seen a version by Spiers that was dovetailed. It is my intention to make a dovetailed version of this plane in the near future along with the Chariot and Thumb planes.
This plane has the advantage of having a badgered mouth on both sides, as on a rebate plane. It can gain greater access due to it's smaller toe. Much sought after by cabinet and instrument makers and therefore was made by most of the early makers.
It was only Norris that incorporated an adjuster in this style of plane. With its adjuster it makes a very desirable balanced hand tool.
The photographs show one of only six planes I have ever made. It will be interesting to see my dovetailed variant of this.
