G'day Guys, I have been taking my time in building this cool model (have received up to part 115) just finishing the first Hull planking as per part 23. Question to you all is, What type of filler do I use to fix the small gaps in the Hull planking.
Regards, Chainfire from Oz

Think it would partly depend on if your going to make your model r/c or static.

i used wood filler on my first hull planking and the second i made sure i put glue not only on the hull but on the edges of the wood to be glued then pinned it tight thus ensuring not many parts to fill on the 2nd layer

I am looking at making it a static model. I dont want to put all this effort in and have it end up like the real Bismarck.

Hi chainfire Filling the planking is a bit of a hassle No matter what, the hull is going to have some movement once its finished. I was planking in the garage and then taking it inside., then back out to the garage for more planking (on & on) to try and keep it in a more constant climate all the time. After 6 months the hull still ended up with fine cracks in the primer. Unless you can find a filler that expands and contracts when cured and is also easy to sand, premix polyfiller is fine. I've had no cracking from the areas I have filled (which was mainly the wood / resin at the bow and stern. With your second planking, try and get the planks tightly abutting each other, then when you sand back, there should be no need to fill Baz |

Hi chainfire
Im building a static Bismarck also. I sanded the hull as smooth as possible, Then filled
any dips with Isopon P38 filler.
Sanded down , then a coat of primer and another sand down. Did this up to 10 times
before I was satisfied.
My Bismarcks had about 15 coats of primer all together
hope this helps

I think that one of the main causes of subsequent cracking is not the surface filling of slight hollow imperfections, but poor edge gluing of the planks. If the planks are not edge glued properly, this can give rise to some contraction or expansion of the planks due to humidity changes. If they are properly glued edge to edge, this gives a more stable and rigid hull.
