NMBROOK wrote:Looking good Alan.You may have noticed already but just check the gunport upper deck third from stern looks a little twisted on the photo.If you chock the hull level fore aft and side to side you can double check your bottom cills are horizontal using a short spirit level.When you come to sizing the ports I recommend sticking abrasive paper to some scrap wood.If you use say 10mm square strip and glue the abrasive paper you can rest the smooth side against one finished edge whilst sanding the adjacent edge,this helps a great deal in keeping the ports square.I used to use needle files but they soon loose their edge doing gunports unless you use permagrit ones.
Kind Regards
Nigel Thanks Nigel, especially for your eagle eye..... that port was about .5mm out on the right side which is why it looked a little twisted..... corrected now...  .. Am now in the process of making a cradle for the old girl to hold her steady and level on all planes... As I said, my intention will be to double check each port in turn just before I start cutting and will also look to use your method of using a square strip with sandpaper glued to one side.... It's always the simplest methods that turn out to be the best..... Thanks again for pointing out the flaw.... On the subject of the hull profile, I have been checking my hull and also looked back through the pictures I have posted along the hull profile and for the life of me I cannot see the dip you are referring to... maybe I have been lucky I don't know but am sure we will find out for definate when it comes to applying the lower whales....  Thanks again... Regards Alan

No problem Alan sometimes it takes a fresh pair of eyes.I find with something like this you need to walk away then comeback later and most importantly stand well back and cast an eye over everything.When you are marking them out you are up close with the model and especially with the hull shape,discrepences dont stand out.Another trick is to look along the side of the hull from both bow and stern and check your gunports follow a smooth line.With the most accurate marking in the world you may find you have to move a port up or down fractions of a mm.
As regards the hull check stujue's post on the thread he's posted a photo that clearly shows what i mean.
Kind regards
Nigel

Nigel Hi Nigel, completely agree with your comments and it will be advice I will be following... The cutting of the ports are I believe a crucial part of the build, get this wrong and the whole build will be spoilt.... As for the dip in the stern, is this what you are referring to????

Hi Alan, having a closer look at the gun ports you've drawn, it might just be me, but i think the top deck gun port between frame 20 and 21 is a little off? should it not be right up against frame 20? Processing - Progressing
Previous builds: HMS Victory
Current build: HMS Sovereign of the seas

No mate if you look at the hull from above with the hull upside down look at the sides of the hull just before the stern.The dip you are showing is as it should be.
Kind regards Nigel

Hi Admiral, you are spot on and a huge thank you for pointing that out... not only was the port twisted slightly but it is completely in the wrong position.... Port has now been rubbed out and will be done again tomorrow.... Just goes to show the benefits of having other eyes look over your work.... . You're a star.... Regards Alan

Your portside looks pretty good but the starboard looks like it dips in then theres a little hump just before the stern.If you place a ruler where i did you will see what i mean.This last 200mm wants to be straight.
Kind Regards Nigel

Kind Regards Nigel Thanks Nigel, can now see what you are referring to... Will rectify this when I come to planking the second layer.... .. Thanks again.... Regards Alan

Well have done quite a bit of experimentation in order to find the best method of marking and cutting out these ports and finally came up with a method that suits me best... First thing I did was to make up a port jig from a piece of 12x12mm walnut glued onto a 12x10mm piece of pinewood. Using serious glue, glued a small level onto the pinewood...

Cut a piece of 12x10mm pinewood and to one of the 12mm sides glued some fine grade sandpaper.... .. This helps to tidy up the port edges and help to ensure the ports are square.... Gandale attached the following image(s):

Now that is a seriously good idea Alan.I have never seen nor read of this but when you think of it,it makes so much sense.Absolutely brilliant,I for one will be pinching this one Kind Regards Nigel

Just seen your sanding stick,my only critiscism is if you are sanding the ports out to 12mm,how does the twelve mm side fit in as you are opening it up?
Kind Regards Nigel

Next came the problem of ensuring the hull was secure and level on all planes. Build myself a cradle for the ship to sit in and leveled it off... Gandale attached the following image(s):

It has many uses as you will see during the explanation of my process... .. As for the sanding stick, it does fit as will become clear... ports are 13x12 and stick is 12x10... Regards Alan

With everything level and secure marked out the port roughly where they are to be locaated. Double checking all measurements I then got down to ensuring the port was square and level... .. Did this by first marking in the uprights using a set square... Gandale attached the following image(s):

Using the port jig on its side then marked up the top and bottom of the port again double checking all measurements... Gandale attached the following image(s):

Once happy, got down to the business of actually cutting the port out... Using my dremel with flexi drive and router bit carefully cut the port out ensuring I stayed inside the cut lines.. Gandale attached the following image(s):
