Planking processes

[MESSIS]

 

Need advise guys....
So: Tapering the Garboard plank its made on the plankside facing the keel... the other side stays a straight line. All the other planks are tapered on the oposite side. That is , the planks are tapered on the side facing the wale.

 

And ofcourse at the end, the last plank which closes the endgap, is between two straight sides (garboard and last planank facing the wale),  it can be a spilled plank, tapered on both side. Is that correct? Do I get the planking process correct so? Are there also other proceses?

Rather than trying to give detailed explanations, I recommend you read an excellent book (brochure) "Planking the build up ship models" by the late Jim Roberts, or articles on planking that you'll find here, in the "links" part of this forum.

Thank you very much Sir

Problem is cant find it.... could you be so kind and advice me where I can get it?

[mtaylor]

Model Expo used to sell that book, Cristos.   I've also seen it on Amazon.

 

Or go to the top of this planking forum and look at the pinned topics on planking.  http://modelshipworld.com/index.php?/forum/14-building-framing-planking-and-plating-a-ships-hull-and-deck/

 

There's also a tutorial here:  http://modelshipworldforum.com/ship-model-framing-and-planking-articles.php

Thank you mtaylor. Idid found it in model expo as you advised me.... amazon de and uk dont have it.

 

Thank you again

Christos,

 

Don't worry - it's not as complicated as it sounds.

 

Once you have tapered a plank, I doubt whether you will be able to tell which edge is which.  That's particularly true once the plank has been softened (by whatever means) for bending, because when you fit it in place it will also deform up and down to fit to the adjoining plank.  As long as you have marked the frames to ensure a true line along the planking, all you need to do is ensure that each plank follows the line.

Thank you John for your response. If I get it right, you mean that I mark on the bulkheads every strake line from stem to stern?

Christos,

 

Yes.  

 

Measure around the midships frame or bulkhead from keel to wale on one side.  This will tell you how many strakes of planking you will need.  For example, suppose the measurement is 156mm and you are using 7mm planks, you will need 23 strakes.  For each bulkhead, cut a strip of paper equal to the distance from keel to wale, mark 23 divisions along it and then transfer these marks to the bulkhead. 

 

The easy way to do this division process is to draw two vertical lines on a sheet of paper, each easily divisible by the number you have just calculated (in this case 23), one longer than the maximum length around the bulkhead and one shorter than the distance around the shortest bulkhead.  In the example I have given, you might choose 184mm and 92mm.  Divide each one, and join the marks:

 

 

Now you can take any of your strips of paper, lay it on the diagram so that the ends lie on the top and bottom lines, and mark off the 23 divisions.

 

Once you have marked the bulkheads, you will be able to see the line to follow for each strake.

You may find that, as you reach the ends of the hull, the strakes become too wide or too narrow – in which case you will need to think about stealers or drop planks, but that’s a matter for a separate discussion.  You should read the primers on planking elsewhere on this forum, e.g. http://modelshipworldforum.com/resources/Framing_and_Planking/Plank_Bending.pdf

Thank you John for your time and valuable help.... I downloaded the link and am going tu give it a good study, so as with your comment. I think am moving forward now thank you again.

When you lay the garboard be sure to keep an eye on the upper edge - the straight edge. Most people have a tendancy to slide the garboard too far forward. To the point where the bow end wants to start curving upwards. This is too far. What happens is all the subsequent planks above the garboard will pick up that curve, compounding the problem.

 

The trick I use is to lay the garboard against the keel - lower edge in the rabbet - bow end about 2 inches behind the stem. Keeping the garboard in the rabbet, slowly slide it towards the bow watching the leading edge. When you see that upper edge begin to lift up stop sliding, backoff a bit and try again. You want to stop sliding right before the point where the edge begins to lift.

Thank you mikiek.... I think I got it

Just to stir things up - here is a whole different take on planking

 

See post #32. It takes care of correctly shaping the planks for you.

mikiek   thank you. Just went over it... great practical help! Very usefull.
