Chris T, his brother Tom & Dave R all spent the weekend on site again. Chris appears to have turned into our resident pipe fitter, with three more air pipes for the brake frame fabricated in the clean air room. He fabricated a new section of conduit for the fire bottle activation cable in the thin man's passage, making all four runs complete. Six internal doors had replacement locks and handles fitted making all these complete. In No.2 cab all exposed conduits were cleaned up & painted in primer. The window quarterlights were removed & the steelwork behind cleaned up. His brother Tom continued work in No.1 cab, which looks pretty good now, with most of the interior surfaces cleaned & painted, and all the rear bulkhead equipment & the roof lights refitted. Chris B examined the four brake cylinders Mark B brought with him, finding two good ones, one that may be usable & one scrap one. He then cut & drilled pieces of steel which Mark, after tidying up the sales stock, fitted on the inside of the opening doors we are not using in the BG to make it more secure. Ian & Pete freed off & lubricated the cam followers on 'B' bank. The four suspect inlet/exhaust cams cleaned up okay, so hopefully the camshafts will not now have to be removed. The tarp was removed from the power unit so Mark B could phot progress & more oil was smeared round the inside of the liners. I cleaned & fitted the contact tips to no.s 2 & 3 field divert contactors, likewise the copper braids to the no.3 contactor & started reassembling the no.3 auxiliary contact block.
