Thanks for the replies Iíll keep the detail coming until it gets too much for you all  %%  or me  :embarrassed:


Nigel - Could be my next build but I am sooooo slow you probably be waiting for years!


Jim - Iíve seen your build and that is one lovely boat your going to build so Iíll be following


Ian - I think your spot on there. Fortunately the part I wanted to measure was the bearding line at the stern as the planking runs off of the frames and ends up flat along the keel. Iím just going to do it by eye and as long as both sides are symmetrical it will be okay. I think a less confident builder would struggle a bit but could sort it out with s bit of help and advice


tghsmith - I meant to say that your idea of using paint on the frames to help fare  them is brilliant. Iíve actually been using the burn marks from the lazer cutting for roughing out which I guess is the same thing

Hi Mark,
Keep on with the details. My first attempt at a plank on frame was a Dumas kit, which assumed you were a Danish Shipwright. That is a neat tip about the stir sticks (would have to buy some, over here the coffee shops all use plastic ones). With the burn marks from lasers I found you had to sand them off to get the glues to stick.

Hi Gerald you are spot on there mate; I learned that lesson the hard way with my last build so now all of the burnt edges are sanded clean.


I've not much to update this week as the faring process is a slow one for me to get to a point where I'm happy with it.  I'm sure that you could get equally good results without going to the hassle that I do but thats just me.  Any way I thought that I would post a few pictures of my technique of getting this right.


Firstly its difficult to see where you are sanding as matching one frame to another involves so many different angles.  I get around this by marking the frame with pencil to see where I am sanding.  The far edge is my guide and requires no sanding as otherwise I would loose the shape of the frame and therefore change the shape of the hull.  This marking is done time and time again.





Once I've taken quite a lot of the excess material off I then only mark the highest point on the frame; again using pencil.





And then keep making and sanding until I get a clean sweep on the frame.  At this point the frame is just about right.





This process is laborious and time consuming - Its the sort of thing whereby I have to do a couple of hours work and walk away for a while.  It works for me and will make the planking a whole lot easier in the long run and something that I believe is worth spending as much time as necessary to complete.


I've got it wrong a couple of times which has involved bring the frame back up using my favourite coffee shop stirrers.  I have also found that CA is not good for this job it just doesn't seem to give the quality fixing of aliphatic resin.











And finally this is how I check to see if the frames are correct.  I use a 3mm diameter plastic rod and lay it across the frames.  I prefer this to using planks as its got a very small contact area and shows up the smallest of errors in my work.  This little rod has become my nemesis  {-)
Ignore the strengthening on the frames its the light coloured frames that matter.








And thats it for now.  I've got lots of sanding and repairing to do but I am enjoying it which for any hobby is the most important thing.


Thanks for looking - Mark  :-)

Hi Mark,


Lovely work. As you say, the the most important aspect is enjoying and gaining pleasure from the build process.

Mark I am enjoying your build thread. I'll be starting the same kit next month when I get back from a family vacation. I have to say I've learned more in your thread than anything the booklet has taught me so far. My version will be "slightly" less complicated with an electric motor instead of steam. Right now, Iím only in the planning stages trying to rectify the ladder (Google image from another build) going to the 2nd deck?? I do not want to take away too away much from the charm of the design, but there are a few items still to be sorted out Ė at least in my head! Thanks for posting and as far as Iím concerned please be a descriptive as you want. I for one do not tire from the detailed explanation.

Hi Rmay - good luck with your build  :-))   Your electric build should cause you less issues than I have as I've really had to knock the hull around to get the steam plant to fit.


A small update which doesn't look much but there have been plenty of Mark hours put into this.


First up I marked out the bearding line and cut the rabbet on the keel for the planks to sit in.





Unfortunately I discovered that I had been a bit too heavy handed when I faired the first two frames at the bow.  This meant that I had to build them back up again with some wood and then reshape them to the correct level.  This is very tricky as its all done by eye and took me several attempts to get it right.  Now I know it doesn't look exactly amazing but I now know that its right.  I have also finished fairing the one side of the hull.  In this photo you can also see the finished repair on the 3rd frame back.  Honestly these low points are literally slivers of wood and nothing else.





I've also marked out the stern and skeg to where the planking goes too.  This has really caused me to think about how the planking must be done.  Ok I'll try my best to explain.





This is a double planked hull and the planks on the skeg sit on top of the skeg and are proud of the surface. Now if I put both layers of planking on top of the skeg it will not look right as it will be too thick and stand too proud of the surface.
So I only want the second layer of planking to stand proud - So the first layer needs to stop 1.5mm short of the finished line and also be rebated into the keel so that they sit flush.  So my next jobs are to repeat the same jobs on the other side of the hull and then rebate the bearding line at the stern so some careful chisel work is needed to get this right.  I'll get some pictures up to explain this better when I've done it.


Here's a couple of pictures showing the transitions between the frames on the finished side.  Goodness this takes ages but is worth it.








Thanks for looking - Mark  :-)

Hi Mark fine job you are doing ,If I may suggest filling the stern section with balsa as the planks may be too narrow and as I assume it will be painted should look ok

Hi John that's a lovely hull that you are building there with some really twisted planks too that look nice and straight.  Thats a difficult thing to get right and your looks perfect  :-))


I have thought about putting balsa into the stern - but wait for it - famous last words here.............I'm going to try and plank it first as I see this as a real challenge.  Lets hope I win  {-)   If not its balsa all the way  ;)

Hi All


I hope that this photo explains better what I was trying to say with regards to the keel and skeg.  I have now chiseled out a tapered rebate so that the first layer of planks sit flush against the keel on the skeg.  The second layer of planks will sit on top of the first layer and therefore stand proud on the skeg.  The first layer is 1.5mm inside the final finished line too so that the second layer sits where it should.  If that sounds complicated you should try working it out with limited instructions  {-)





This was done on both sides and I'm quite pleased with the transitions between the frames.  I've lost count of the hours of work that have gone into getting this right.  The other thing that I became aware of is as i was cutting the rabbets on both sides the keel strength lessens and becomes quite vulnerable to snapping off.  I just treated it very easily to save any damage.





Then it was a good clean up to get rid of any dust and I also used white spirit to get it spotless ready for the planking.  The hull was put back onto the building board to make sure everything was straight and level.





Now this is where I have had to stop due to the way the first plank is installed.  The picture below shows where the very first plank is laid following the line of the top of the bulwarks.  To fit this plank it must be bent and twisted through both planes which ironically goes against planking in general by not being able to let the plank lay naturally.  I can see why its has to be done this way and because its the top plank the curve should reduce as it comes lower down the hull.  Anyway I've tried and tried and I've realised that this plank is not going on without being nailed to I've ordered a tool for the job.  The plan is to fit three planks on the bulwarks to add some strength and keep the whole thing straight, and then turn it over and start at the garboard plank against the keel.





I hope that all makes sense?

I've managed to get a bit more done but not much due to having man flu  :((


Now this first plank has caused me a few more issues than it should have to be honest.  Firstly the picture on the plans which shows where the first plank goes is really just a "This is roughly where it needs to go" picture and is just a representation.  The builder has to make their own decisions and I have had to try to get the best possible position mainly by eye.  Anyway as per usual it has taken up lots of hours and in the end I just stopped over thinking it and put it on.


The other problem was that I found that the stern wanted to twist when the planks where installed due to the twist in the planks applying pressure to the frames.  I cured this first by making a temporary support at the stern which looking at the pictures is a bit over the top  %%





Then the first plank went on and I've tried to keep a nice clean sweep in its lines as the plan suggests. I gave it a bit of a soak in some warm water but this lime wood is very flexible without getting it wet.





And it was extremely satisfying to see that all of the effort that when into cutting the rabbet has paid off. A nice clean joint on the bow with the plank.





And then for the other side - I've used a mixture of brass push pins. map pins and clamps to hold them in place.  The brass pins have been left slightly proud as they are all coming out once the aliphatic resin has set





It doesn't really look much, but this is quite a mile stone for me in this build.  Its also one that has really made me think about how to get the best result from the planking.  I just hope that I've got it about right.

Hi Mark usually the first plank is the garboard plank which is the one next the keel then continue with exact pairs on each side. O0

Hi John - yep I fully agree but the plans on the kit say that this is the first plank to be laid (well in Italian).  My plan is to put 2 more planks below this first one on each side to give the hull stability and then turn it over and make the garboard plank.  That way I can then come off of the keel straight with the following planks as a said in my previous post.


I'm sure that the reason for this is due to the way the frames are supported by the false decks that are supplied with the kit.  I guess that normally the basic framework would be fixed to a board upside down to keep it all straight.  Therefore the garboard plank would be the place to start and build from there.  Bear in mind that this is my first POF build so I do need to follow the instructions up to a certain point.

Hi Mark I really hope that you don't find my comments derogatory ,but as a scratch builder and thrown at least one crooked hull in the bin ,lesson learned ,and without the help and advise from fellow Mayhemers I doubt I would still be building model steam boats.
I am not into kit models but it can be seen on your plans that some planks will be pencil point thin at bow and stern ,will the model be painted or glass fibre?
Cheers

Hi John all comments are welcome on this thread as everyone has a different point of view, and I like the way fellow Mayhemer's care about each others builds.


The hull is to be double planked and then it will get a coat of resin and cloth and be spray painted as I've had nice results doing it this way before.  Ignore the picture on the plans as its just a rendering and is not really representative of the model as I've discovered going along.  I shouldn't get many thinly tapered planks as I'm going to use drop planks and stealers.  Getting around the propshaft is going to be tricky though.


Anyway I've planked the bulwarks and they have come out quite nicely.  This is quite important as the bulwark supports are all removed once the deck is in place so it needs to hold its shape on its own.  I have had a little but of clinkering on the bow due to laterally bending of the planks but nothing thats bad and its only slight. I shouldn't get anymore as further planking doesn't need to be bent that way. The hull is also nice and straight so here's a few Pictures.


The planks are fitting very nicely into the rabbet on the stem











The planks cut to length at the stern





Looking from the inside








And above at the bow stem





They are glued using aliphatic resin as I like to glue the planks together along their entire length which seems to remove any springiness that can occur.  So far so good and the next stage is to turn the hull upside down and make the garboard strake. Then I'll start planking from the keel upwards
