Planking Lady Nelson questions

[Bostaevski]

Hello

 

I am building my first* ship, the Lady Nelson.  There is this stop-motion video on youtube that shows the planking, and when they measure for the 10th bulkhead they only measure the bulkhead itself and not the space that goes from the bulkhead to the keel.  Surely the measurement needs to go to the keel?

 

A few frames later in the video he has his chart showing how to taper each plank.  If I were to taper all the planks based on this then there would be no planking between bulkhead 10 and the keel...?

 

A couple other questions:
* Is it correct that when you taper you always taper the top of the plank so that the bottom of the unbent plank remains a straight line?

* When you bevel/chamfer a plank so it will fit better against the next plank, is it best to chamfer the bottom of the plank?

* Am I better off in the beginning to cut each plank individually, alternating between starboard and port?  Or should I try cutting them in batches?  I tried using magnetic jaws on my bench vice but they aren't strong enough to be stable when I clamp down on the planks.  I've ordered the amati plank/hull holder thing but I don't expect to receive that for a few weeks - so for now I'm tapering with a straight edge and hobby knife.

* Is there a way to unglue something?  There are two pieces at the stern that I somehow glued on crooked and after reviewing the plans they are supposed to be parallel with each other.  I glued them with both CA and PVA.  I was thinking of possibly just cutting them off and fabricating new pieces on the scroll saw.

 

Thank you so much - I apologize if these are FAQs.  I've tried searching but am a bit overwhelmed and not even sure what the correct terminology is that would help in my search.

Yes.

if you glued something with CA, it's not coming off again, trim it off and make a new piece you can glue on correctly.

 

I'll let others answer the planking questions, as I did my planking in a totally different way involving tapering the planks once they're already on the ship. But it requires very sharp matching single-bevel knives to work, so it's not something I would recommend to most builders.

BTW your best plan is to start a build log so you can ask ship-specific questions and get help from lots of people.

Isopropyl will loosen PVA and acetone will loosen CA. Be careful as you don't want to get it on any finished parts as it may stain them.

It doesn't really matter which side you choose to tapper, just pick one side and stick with it. Theoretically you could just cut the correct curved shape out of sheet stock, but using strips you need to do a combination of edge bending and tapering to get them to fit right. You should be able to just place the plank in the right place without any effort if you have done it right.

I do planks individually, but do one on one side then one on the other. The reason is to make sure that the plank ends at the bow and stern are lining up with each other.

 

You should check out the planking tutorial videos (look under modelling techniques in the top bar). Also take a look at some of the build logs for people who have done similar ships. As @vossiewulf said starting a build log is a good idea.

 

Good luck.
