Inner Bulwark Pattern not matching the Gun Port Pattern

[mrcc]

I am at the stage on my Caldercraft Granado build in which the patterns do not match. I knew earlier that I placed the gun port pattern low (by mistake) by about 4-5 mm at the bow and 1-2 mm midship but need help from any members who may suggest the best course of correction. The patterns match perfectly laterally in the openings.  Thank-you!

Julian,

 

I think you can correct this by adding some scrap wood to the top edge of the outer gun port pattern to match the inner gun port pattern.  Then you can add some scrap wood to the bottom of the outer gun port openings and cut the upper edge of the outer gun port opening to match the opening in the inner gun port pattern.  Basically, you will rework the outer gun port pattern to match the inner gun port pattern.  I think it is essential that everything matches the inner gun port pattern.  When you install the second layer of planking on the outside of the gun port pattern, no one will know of the modifications that you made.

 

Many builders of this kit have had the same problem.  Maybe someone else will have another solution.

 

Glad to see that you are making progress on this kit and I am sure that the gun port issue will be only a minor set back for you.

Thanks Ryland for your advice and direction!

On the face of it it looks like the outer gunport ply is too low to the inner bulwark ply - two options build up the outer or reduce the inner , either is a lot of work I suspect. You need to keep an eye on the channel positions now otherwise you will encounter problems in the deadeye stropes and metal work being to long and terminating in the wrong position.

I had the same problem on my Granado currently underway but not to the same degree. My outer patterns were too low by about 2mm at the bow ports and I built up the upper edge of the outer pattern and refilled and framed the outer pattern to match the inner. Before hacking away I'd suggest measuring carefully off the plans to establish the true height needed. It's most likely the inner gunport is closest to correct as it should sit almost directly on the deck, which - as it is essentially the top surface of the framing bulkheads is the truest level. Most other measurements and placements stem from this - ie the level of the gunports to match cannon height. As Norman says make sure there's going to be room for fittings like the chain plates on the outside of the hull first.

Thanks Timmo for your reply and advice. I noticed your build log and it looks great. You are right though and I am reworking the outer gun port pattern to reflect the inner profile and port holes. Cheers, Julian
