Nigel, what an excellent discovery! I have been using pencil, marker and black paper and all have their pros and cons, This looks like it is the best method. I will have to search for some black tissue paper as well. Great work on your ship so far.

Not a very exciting update today,however my experiment has been a success.I have been debating about caulking techniques and despite using a pencil for longer than I care to mention,it never looks as good as the black paper route.However after watching Dr Mike's dvd explaining that black paper prevents proper glue bond strength,himself using cheap white paper and dying it black,I wanted to find an alternative with a bit less faff Having to visit town today for other reasons  I did stumble upon black tissue paper.I thought this would still allow proper penetration of the glue,but would it be easy to work with?I adopted worse case scenario for the test and cut some planks roughly(not even changing to a fine blade )on the table saw.Smearing one edge of these with alaphatic and placing them on the tissue edge on.Having left to dry for a hour(would really leave overnight in practice) and then cutting the tissue with a new scalpel blade close on the underside and a little above the face side,separated the planks.These were then glued to a sheet of ply.Two hours later this was scraped and sanded back.Again I would leave overnight but I was being deliberately rough for the trial.Anyway complete success.No issue with the tissue paper wanting to drag out of the joints as it was fully impregnated with glue and razor sharp black(not greyish you get with the pencil) lines.The only imperfections are from the rough edges of the planks.In reality these would be smooth .I wanted to crack this dilemma as this technique will be used on the whole build which includes the scarph joints in the keel and the hull planking so strength is important.A couple of pics but the difference between this and pencil isn't truly conveyed with my iphone camera.

I have started to fit the upper hull starting from the stern forwards.By notching back the temporary stringers,I am able to use plain pear strip overwidth,rather than trying to develop individual shapes for each of the frame sections.There is a not very clear photo showing this.Each piece was fitted with an obechi infill individually.By using the digital vernier to check running dimensions as I went along,this avoided any accumulative build up of error.The obechi was thickness sanded(using a sanding block   )to suit each location.There is variation in frame spacing due to working with the constraints of bulkhead positions,but it is so small,it unnoticable to the eye.I have set the obechi 2mm above the base of the upper trim(bottom of the ebony planking).This is to allow fine adjustment of the ends and then capping with 3mm boxwood.Doing it this way means no tool marks will be visible on the frames from shaping the ends of the obechi.This complete section has been trimmed 3mm below the cap rail so I can fit a square pear 'binding' stringer to tie everything together.I got this idea from Dr Mike and makes alot of sense to tie all these laminations together.It also provides a sanding guide for upper frame thickness.This will be pinned later into the top of some of the frames for additional strength.The length of this upper edge is overlong at present and steps down to a lower level,which will be cut back when the next section is complete.My technique just leaves a section to sand back when the temporary stringers are removed.I am considering replacing these afterwards,but bolting to the hull with M2 bolts as this area will be planked over.I am also considering using threaded rods as well to keep the upper hull the right distance apart as work progresses.

Hi Chris
 
I think not only does it increase the glue area but also the rigidity.When I used to build on open bulkheads all the time,using kit 1.5mm first planking and the 1mm second,I used to find the hull flexed when sanding.You only have 2.5mm of material,take away the amount removed from sanding and in my opinion you are left with a very thin hull.As I mentioned earlier in the log,if the model gets exposed to increased humidity for any length of time then dries out again,this can result in the bulkheads 'ghosting through' in the finished profile.As I build models to outlive me many times over and if sold on have no control of the environment they reside in,I like to adopt a little extra 'insurance'.It is more work,but time is saved by not having to remove much material when sanding planking.Sovereign was double planked over a birch ply infilled hull,The two layers of planking over the top only needed the minimum amount of work to sand smooth.IMHO it is well worth the extra effort unless of course you are building a POF or model with many bulkheads where the planking is adequately supported.

Hi Nils
 
The infill is my own addition.The kit is open bulkheads and double planking.I am using single planking of scale thicknesses due to the exposed framing on the upper hull.The planking will be spliced at the waterline,Ebony above and boxwood below.The bulkheads would not provide the necessary support for this procedure with single planking .I would have probably infilled anyway as it is my own preference but also there a many complex curves to this hull and to ensure everything is faired properly this is easier in the long run.

Work continues moving forward with the framing.When it came to sanding back the inside,unfortunately the 'binding' stringer that will be fitted at the top falls below the level of the temporary stringer on the outside.I measured the overall thickness including the outside temporary stringer on the thinned section on the stern using the verniers and used this dimension as my point of reference to sand down and profile the central section.Work now concentrates on completing the obechi infill.I have already started at the bow,this will need increasing in height at the sides as the hull edge flows down in an arc to meet the stem.

My trial with black tissue paper has been a success.Using a similar technique to Steve,the tissue was glued to the plank edges first,trimmed back and then the planks laid in the normal way.The glue fully penetrated the tissue so there was no issue of it 'tearing out' when sanding.The glue penetration was an important issue for me as this will be used on the hull planking and keel scarph joints as well as the deck.Having used a pencil for many,many years,I do feel that this gives a superior look that is jet black without the greyish tinge you get from graphite.The picture doesn't really do it much justice and the planks were rough cut for the test(I didn't even put a fine blade in the table saw)

I use a Chinagraph Pencil on one edge of the planks, as seen on the deck of my Xebec.

Hi Matte, I totally agree with Nigel about making a dust cover for the ship. Take the opportunity to make it a lot bigger than the permanent case to enable you to take it off and on the ship without catching it. I'm due to start my Wasa / Wasan / Vasa now and as soon as I can get my daughter to show me how to post pictures I will start a build log. Coincidentally, the ship looks more like a log in it's present state I wont start it until I learn to post. Theres no way that I can come anyway near your beautiful build but your log has been, and will be a source of inspiration for me
Tony

Matti,
 
Looking better than ever.  What Nigel said about a cover up is a good idea.  I've done a similar thing and recommend it.

Work continues moving forward with the framing.When it came to sanding back the inside,unfortunately the 'binding' stringer that will be fitted at the top falls below the level of the temporary stringer on the outside.I measured the overall thickness including the outside temporary stringer on the thinned section on the stern using the verniers and used this dimension as my point of reference to sand down and profile the central section.Work now concentrates on completing the obechi infill.I have already started at the bow,this will need increasing in height at the sides as the hull edge flows down in an arc to meet the stem.

I think Matti you may be better of making something temporary like a light softwood frame and even just covering that in clear plastic film stapled on.You will have to lift it on and off many times so something a light as possible but still offers protection from dust is adequate.I know it won't look glamorous   but it will keep the dreaded dust at bay while you are still working on the model.
