Too bloomin' cold to put filler on, its about -1 in my garage at the moment!
Decided to tackle stern end instead, easiest solution I think is to glue blocks of balsa together, then sculpt it to shape then glue it to the deck, then I can tackle the bulwark rails. Not looking forward to that as lots of fiddly bits to make and fit, cold sausage fingers are not ideal............
I did manage to get some more pictures of the Granit so these are going to help with the build and also some of her sister ship Bazalt in dry dock, helpful for Kort set up and stern as she is slightly different from the drawings I have worked from, nowt major thank goodness.
Ta for watching, will post more pics of progress when my fingers thaw out!
