Update on the sumwings (2)

The sumwings are finished but not yet complete. That comes when I give them their final positions.

Update on the sumwings

Some progress on the sumwings, It's not an easy shape to make but I am satisfied with the wings I have now. After this I start adding the details (which are many) And then I want to figure out to find a way to make the fishingnets. (I eat lots and lots of garlic these weeks. Maybe next time I tell You why)

Sumwings

I started to build up the back of the ship but when i was looking at the photo's I realized I have not build yet the most important piece of the ship. Its called the sumwing and it is a Dutch invention to drag the nets over the seabed with less agitation off the bottom and less fuelconsumption. The sumwing 'flies' over the seabed draging the nets forward. The pulswires attached to the the sumwing and the nets give electric pulses which makes the fish jump up in the nets.


On  http://www.sumwing.nl   You can find more images and some video about the sumwing.

Next update I hope to show you my finished model sumwings

Kind regards, Kees

last update on the mast

One of the last things to build on this ship are the portals on the back of the ship. This portal is placed a few years after the ship was build. First there was a crane and a rubberboat

The portal is used for the two puleys that guides the pulswires to the nets

Here the placing of the portal


And how it looks now



No drawings so I had to use photo's for measuring the right dimensions and proportions









And the last video from tonight

Video: Building a mast

Today I build the mast on the aft deck of the ship. I made a video..... But don't worry.... No more talking in the next video... just some writing..... which you can skip.....

Enjoy the video and keep on scratchbuilding

Take care You choose the right glue..... :-)

Pulswinch and another block again

Hello to You all.

Today two parts I finished.

At first the block which is used to haul in the sumwing. Sumwing is the wing on which the net is attached. It flies over the bottom. In this block there is a big pully which I made on the lathe because it is very vissible.

Example


And how I made them. The coin is 1 inch in diameter




And I made the pulswinch. The ship works with pulsfishery (most Dutch beamtrawlers do). It means that the nets fly over the bottom and instead of chains (that goes trough the bottom) there are electrodes whitch give short electric pulses. The fish are disturbed and 'jumps' into the nets. The electrical current comes from a cables whitch is reeled in on the pulsewinch (2 on each ship)



And how I made them. They are very little (18mm) so I had to compromise a little, some times.




And a little bit off topic but I think it is fun to show you. This ship is made/finished by my father last week. It is in scale 1/100 and 43 cm long. The ship is the 'old' KW88 Pelikaan. I made a few trips on the trawler when I was a boy. My father has always been an example to me when it comes to shipbuilding so I am happy he has build this ship.
