The circular cross section bridge has become a distinctive feature of my planes of late. It is fixed in place using integral riviting - the same technique used to join the sides to the sole which gives superior strength and ridgidity compared to more traditional fixing methods.
The adjuster recess is milled along with the blade bed - both surfaces are in true station, I decided not to fix the adjuster as it only needs to be positioned.
The adjuster will support the rear end of the blade in line with the frog which makes up the blade bed. The adjuster is allowed to rotate and position the blade,
this system was also used on the No.98 (excluding the retaining screw).
With this plane I have returned to integral riveting as first used on the N0.98 (also fabricated from stainless). The rivets have a small leading chamfer which also helps to prevent splitting when it comes to peining.
Many people who read my blog and visit my instagram and facebook pages enjoy the workshop pictures I post there showing my work in progress.
Some time ago we collected pictures of my last A13 build and published them together under the heading 'Making the A13'.
Although this was never intended to be an exhaustive documentry of a plane build, it does go some way to illustrate the variety of processes and number of hours which I put into making a plane.
I also tried to show some of the unseen work which goes into my builds, such as the custom tooling, work holding jigs, setting up for milling or lathe work and of course all the handwork such as filing and sanding.
This article has now been made into a PDF document which you can view on the planes / in depth / making the A13 page.
It is best viewed on larger screens as it is A4 page size and runs to 50 pages in total.
