Planking calculator advice.

[John Murray]

Evening, I am starting to get close to 2nd planking on my Victory Models HMS Pegasus. I think I have the idea of a planking fan sorted out. Does this look a reasonable way to approach this? Do the calculated tapers seem reasonable?
I have seen other more involved methods but being my 1st wooden model in 40plus yrs, I think this will do for this one.

Impressive work on the calculations.  I am by no means a planking expert, so I will have more questions for you than answers.  
 

are you planning on edge bending your planks to achieve the required curve at the bow, or will you be cutting curved planks out of sheet stock?   If you are edge bending will you make the tapered planks based solely on you calculations?   
how will you handle the taper required from your last bulkhead to the bow or stern?  
 

I am near the end if my first successful planking project, so to repeat, I am not a planking expert, but you will likely need to adjust and fit these based on the hull and not just these calculations.   They will be a great starting point.

I measure the run of each bulkhead once the first planking is done and pencil them in on the hull at their appropriate bulkhead. I then do a run of 10 planks and remeasure allowing me to adjust plank widths ahead of time repeating every 10 planks. This prevents me from running into trouble and having to use a drop a plank or stealer. I do trenails and plank lengths in scale. To help facilitate this I may add false bulkheads where needed to allow me to stay below 20 feet to a plank in scale.

There are a number of posts regarding the use of a proportional divider for calculating the number of planks. You might find the information helpful.
