	Now we have a set of sections. These need to be glued together and then reinforced with dowels.
	To glue the sections we need a gluing jig as we will need a production line for the 26 sections. The gluing jig needs to have glue slots so that the sections do not end up being stuck to the base board.
	Here's the gluing jig in use on the first section.
	The baseboard for the routing jig has been built. This will have strips of wood added to the bottom sheet to hold the section in place while it is being routed.
	Before the sections can be routed, Tony will fit dowels and then glue them in place. This adds strength to the joint.
	With the glue set on the section, routing can start.
	The router cutting bit has a support bearing which runs in the jig slot. The dimensions of the jig ensure that the cut will form the correct dimensional profile.
	This upside down photo shows how the sections will form the core box. The lugs on the outside are easily removed. Only 21 more to do! The motion cylinder core box is relatively straightforward as it a constant dimension through the cylinder. The valve cylinder will be more difficult as it has a number of galleries and will require sections of 3 different diameters.
