Hi Brian if I’d built with balsa I would simply have sealed it with thinned down varnish about 4 coats rubbed down with 240 grit sand paper/wet or dry used dry. then prob used a spray can of red primer. as I did with mine and then mask of below water line spray the black then mask the whole outer hull and use white on the decks. make sure you allow each colour a couple of days in a warm place (20/25c) to dry before masking. the smaller items on deck like the crane’s masts and funnel I brush painted before fitting then the finall step was a couple of coats of satin lacquer to give a uniform finish to the paints. the sprays I used were Acrylic colours from a car spares shop, cost me about a £5 er a tin and used only 3 in total with plenty left over. the thinned varnish will also adequately seal any card you may have used in the construction.
my pulleys were bought from
here the larger ones have a 3.5mm hole through the centre and I threaded this to suit a 4mm threaded shaft then fitted it with a nut and washer either side. the little 10mm pulley has a 1.8mm pilot hole and this I drilled to a tight push fit onto my JP400 motor shaft.
Hope this helps
Phil
Ps nearly forgot about the figures they are HO scale figures bought from a model railway shop.
