Some progress today.  Work on the three remaining half-drop windows continued with cleaning and preparing for paint the fixed-glazing bottom clamp bars.  This involved the use of citric acid to remove the aluminium oxide from the corrosion pits, luckily this is all on the inner surfaces where these were screwed to the steel window frames.  It is surprising (and annoying) that Weymann did not at least give these a coat of paint as a barrier between the steel and aluminium to prevent electrolytic corrosion.

The completed first window has had as much excess sealant removed as possible whilst it is on the bench and all the steelwork has been treated with waxoyl on top of the paint to seal any exposed metal.  It is now ready for fitting.

The aluminium waistrail panel was fitted in the first bay today, this was a pre-requisite for fitting the window.
