Yesterday was spent completing and painting the new gusset plates and the two extra brackets for the replacement OS upright (no.3 in the boot counting from the back).  I also cut a piece of hardboard to exactly half the length of the boot steel closing panel so I can use it as a template.

Today the two for upright no.3 were installed.  I also cleaned and primed the outer faces of timber that form the frame the boot closing panel is mounted on.  Once this is dry they can be painted with aluminium paint then the closing panel can be cut and fitted with screws and coach bolts.
