Ice breaker IJN ODOMARI meaning night (大泊)


ODOMARI was purpose-built and equipped as the first Japanese naval icebreaker. The hull had modern installment of ballast tanks to be able of a rocking hull movement for better icebreaking capability she performed icebreaking and fisheries protection services up in northern waters. The Imperial Navy established guard districts in the outer portions of the Japanese Empire Odomari were based at The Ominato Guard District had responsibility for the Kurile Islands and Karafuto. In 1937-38 Odomari was rebuilding with a new strengthen bow as well as raised hull after. Remaking consists of the fore bulwark and enclosure of the upper bridge etc. She survived the war and the intensions for using the former icebreaker as repatriation transport ship was abandoned due to the heavy insulation. Odomari was laid up at Yokosuka in until 1947 finally broken up at Tsurumi in 1948-50.


Building the model:


I draw the model on millimetre paper in scale 1/700. Here after the paper was glued on the styrene plates 1mm thick for the decks -now very easy to cut in right shape. The most important parts were: waterline bottom, main deck and upper deck. Between the decks I added correct height spacers of styrene plastic bars. When the glue was dry I filled the huge holes (not very huge in scale 1/700) with plastic putty - Next day the sanding process was preformed - easy as the styrene plastic decks was fine guide markers of how much sanding required. The plating was attached by stripes of masking tape. Anchors were PE-set parts from Lion Roar.


The decks was given some planks (acto-knife blade stacked - for further explanation please look on IJN HOSHO build process) to give parallel groves. Homemade anchor chains were added as well as cable drums and bollards of styrene plastic. 

Guns and boats:

The main guns are surplus from Pit Road spur as well as the boats. The small AA guns are PE-set (13mm) and Pit Road plastic (25mm)


The most challenging parts were the swan neck vents 14 in all. But when the technique was fund by my Dremmel tool it was easy. This is all styrene plastic from Evergreen incl. the stacks. Floodlight was surplus from W-spur. PE-set parts mostly from Lion Roar and Tom's model Work's and GMM merchandise - ship etc.


I chose to give the model the usual Kure gray, but the most famous picture of the ship in her early day show a very dark paint scheme - IJN Aux. where black up till 1925. Here after they also where gray (Thanks Juergen).



Itís hard to give any conclusion as the model is totally homemade. But fun it was indeed. I'm sure this is not my last scratch build project. -Very cheap too.
