Making planes can be a difficult task, but the most difficult part is actually finding good information on planemaking and how to go about it. Handplane Central simplifies the process somewhat by providing a wealth of information and various tips and tricks on making planes, as well as the tools and materials necessary for planemaking (and how to make the plane making tools themselves in some instances).

Other Notes: An extraordinary and very rare plane (there are only four known to be in existence) which can change the bedding pitch of the blade through an adjustment of the specially designed frog. There are two types known of this plane and it should be noted that, with so few planes spotted in the market, its difficult to readily suggest an "average price".
