Hey Eric, great to have you along for the ride. As you know I need all the help I can get with planking especially on this small bendy beast. I have started from the garboard up and am indeed tapering the planks. The supplied wood is complete rubbish but I am trying to use it. I received some lovely lime strip today which I can use now before my language gets too bad !! The second planking is walnut strip which I have never tried before. I have always had sapele before. Any tips in advance before I get to it ? (I did get some new walnut in case!!)

Thanks for that Popeye. I thought that's what might be best. I understand the 'stealer' and such but my idea was that if I got the first planking right it would make the second so much easier. I think most of my difficulty, apart from being a rubbish planker, is that it is a very small boat for such a bendy bow ! Re the PM's. I don't understand - I have received nothing from you ??

Please can someone tell me where I went wrong. I have had trouble before because I didn't taper strakes enough so I tried to make sire I did enough early enough. I am however left with a very unpleasant hole to fill in and some clinkering at the bow. The remaining spaces with my current tapering seen to be about right but I am going to have a big hole from about bulkheads 1 - 4. So, not only what did I do wrong but what should I do next ? I don't think I can strip anything off because, as I usually do I glued stuff on too well.

The first planking is taking forever and I think the bottom part is going to be a bit 'patchwork'! It may well be that I over tapered some of the bow strakes to early. Anyway, I will get it covered and adjust my technique for the second go. Whilst waiting for soaking wood to dry I have been making the top rails. This involves laminating 4 pieces of 2mm x 1mm walnut together whilst bending them in jig. Not an easy task! On the outside a further 2 pieces, one of walnut and one boxwood 1x1mm have to go on the outside. There is less than 1 inch of excess wood !!! I have surmised that Mamoli kits are not for the fainthearted and definitely not for the beginner.

This is the best google translate could manage so thank you Hubert. Very helpful. The only comment I would make is that I NEVER use contact adhesive. It is horrible and totally unforgiving. I always use white wood glue or occasionally a very small amount of CA. Hi Mike, here an article from me in German for my forum on planking. It is an absolute MUST that the straightening of the ribs with a strake-line (as it seems to me, for some a disagreeable, but by no means exceedingly important work) is carried out with painstaking precision. Also, a Auffütern on the ribs can sometimes be necessary to ensure the lines. What is ground too closely here, must later be compensated with spatula and regrind and multiple labor input. , For the Unterbeplankung I cut myself with a large circular saw with guide rail of 5mm pine board bars with ~ 2.5mm thickness. There are then quite a few tenths mm tolerance in it. The bending of the strips at the bow is done by slight buckling in 5 to 10mm intervals, depending on the desired curve of the strips. This allows me to bend the bar practically as I want it and need it. With the bending pliers in about the same kinking effect is generated. To the rear of the bar must then be partially twisted in order to sit well and over the entire surface of the frame. This works perfectly with the spruce strips. It is glued with express wood glue and the strips are fixed with model needles to dry. Glued is not only on the bulkhead, but also (important !!) the whole length of the strips with each other. This results in a very compact, solid hull at the end. Due to the thickness of the strips, I have enough "meat" when grinding to produce a nearly perfect outer skin. Due to the tolerance when sawing the strips, it may happen that in places minimal fillings with wooden spatula are necessary. The shape of the plucking is absolutely nothing nachzuspachteln! A perfect Unterbeplankung I need it because the 2nd planking is done only with veneer (0.6 to 0.9mm). With this thickness, I could hide absolutely no more mistakes. The veneer is applied with contact adhesive. For the hull with liquid veneer with gel. Gel is cleaner to work, you do not smear everything completely and it does not pull strings. First apply the bar exactly with little pressure then a slight gap can still be pushed. Only with perfect fit press the bar. With a small metal ruler, the bar is then finally pressed. In doing so, I drive with the front of the ruler over the entire length with great pressure. The quality of the strength of the contact adhesive is achieved by the force of Andruck`s, even if it takes only a short time. The high pressure can in turn be exercised only if the Erstbeplankung has the appropriate strength. The first plank has to be laid as planned! As far as mine, for me very good working method, Greeting Hubert

Hi Brian - great to have you along ! You know I am rubbish at planking. Stick your oar in as often as you like. I can't for the life of me remember but did you know that someone has bought Mamoli and is producing a lot of their kits again. Someone on here will know who it is. The false keel and bulkheads are incredibly pale - perhaps they have been unwell - but they are definitely not plastic.

Thank you for that. I thought you had some crafty method of getting the taper right and you progress down the hull. My method with the pins is OK for the top planks but I think I will just have to guess the lower and back ones. Lots of folk have tried to explain the 'fan' method and tick strips but I just can't get my head around them at all.

Thanks for that. Yes I have had a look and see what you meant about the almost straight top. I had decided following your suggestion to do something similar. I know I will have a lot of wood to remove later to get the shape right but I think it might work. The supplied wood is supposed to be lime but it is a very strange colour. Very yellow ! I had soaked it for ages but it just wants to fall apart and split along the grain, it's not a problem I have had before. I have found lime to be quite obliging in the past. This is due to be double planked so I am just going to aim to get the hull covered for starters!

About the NRG
If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.
The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.
The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
