Yes I looked at that and thought how much easier it would be if I could tongue and groove my planks. I'm not really up to it though on .055" thick planks. -
Yes Eberhard - Thank you for the video, I found it very informative - what a lovely yacht.

Planker's Progress 5 - Day 9 I had a bit of a frustrating day today so I took it out on paper:- Planker’s Lament. I scratched my head and gave a sigh. The plank won’t go. It lies awry. Its tortured course. From stem to stern. Describes an arc of some concern. Concave, a twist and then convex. Its aim, I’m sure, is to perplex. I scratch my head again and sigh. And wonder where the time went by.

Jon An interesting little project which I will follow with interest. Seems to me that the new will be much more extensive than the old!

Dan It is always a good Sunday afternoon when one of your updates appears. Lovely work on the funnels.

Isn't it annoying when your fingers are just too big. Very nice work despite your finger problem.

Planker's Progress 4. It's now day 8 of planking and I am about half way. Most of the time isn't actually work, as glue drying and thinking take their toll on productivity. I continue to work my way up the stern and I am managing the symmetry reasonably well. I have started to cover the rear of the keel in preparation for the next stage of planking. I am still cutting the fine angle at the plank ends with a razor saw but increasingly it is becoming a compound angle with the saw cut currently deviating by about 15 degrees from vertical. At the bow I am starting to move on to the flatter section and in consequence the port and starboard planks are overlapping along the line of the keel. As I complete a plank I sand the end flush from the opposite side and then notch it out to take the next plank ( a bit like interlaced fingers). 80 planks are now in place. Over the next couple of days those awkward hull / keel intersection planks will go on (hopefully).

Funny you should say that - I just sat down for a cup of tea and as I mused on todays progress I thought "I have spent most of the day wondering how I was going to do the next bit. Welcome to the indecisiveness club!

Ah I see, only 3 years to go. Tweezers - I bought a set, my son bought a set - the manufacturer probably never knew why his sales took off.

Eberhard. Yes I will need to manage the "flow" of the planks quite well particularly at the hull/keel intersection. The mahogany I am using beautiful close grained stuff but being 100 years old it is somewhat brittle and hence does not like challenging shapes. Thank you for your earlier help with SV Eduard. We obtained a copy of the book you recommended and also turned up an image from the family photo library. My wife's grandfathers Masters Certificate specifically states he was licensed as a Master of fore and aft rigged vessels. She was an elegant looking vessel - at least until UC-70 got her.

Paul. She is looking good for a 4 year old. I once took 20 years to complete a model so you have a way to go until you can claim she is a veteran build. 12 deg C in my workshop for the last week, I assume you are benefiting from the same mild conditions? P.S - we must have all bought those nice cheap tweezers.

Thanks Pat. Im hoping it will look much better when sanded. I need the finish to be very smooth.

Amazing work - almost impossible to believe.

Planker's Progress 3. Michael / Pat - thank you for the feedback. Another 2 days gone by so that makes it 6 days since I started. I am still progressing with the easier planks i.e. those where the curvature is relatively gentle. I don't need to do any heat or steam bending at this stage. The most awkward aspect is the twist that occurs as the planks turn from the more vertical side on to the more horizontal stern. You can see the twisting region below the 7 pins towards the right hand side of the photograph below. The stern planks are progressing quite neatly. I am taking care to eliminate any potential gaps between the planks. I also used circles on the bow to ensure symmetry. It is more obvious in the following photo how the circles assist with this task. The flat keel line will be covered by a keel plank before sanding to a "sharp" line. Finally a side view of a section of planking - pleasingly gap free.

Plankers progress 2. Days 3 and 4 were reasonably productive. To keep things symmetrical I dew a series of circles on the underside of the stern. As I planked I checked that the plank intersection with the circles were mirror images on each side. Slight adjustments were made by sanding the appropriate plank edges as part of the chamfering process. I I also did the circle trick on the underside of the bow. Progress looks better than it actually is - I estimate I am a little under 1/3 of the way through. My circles on the stern however are disappearing at a pleasing rate. The side view gives a better impression of progress. The stern view shows that I am not following the previously drawn (parallel to deck) lines. I am finding that my guess that I need to taper the planks at the stern by half their width is proving to be about right. About one plank in 5 is going in as a parallel plank. At the bow I need less taper and every other plank seems to want tho be parallel. I'm expecting the next few days to see some disruption. I have been left "Home Alone" to look after the dog. Progress may be slow.

Pat, I'm not sure that it is the grain direction. As I am using salvaged mahogany it could just be that this was on the surface and over the years had become encrusted in grime and is contrasted by the freshly cut planks on either side. It is in a position that I was planning to paint so I think it will be alright.

I am calling the next series of posts "The Plankers Progress" - Chaucer is probably turning in his grave. I am going to try to post this as I progress to give an idea of my (slow) progress. Here goes with the first 2 days of achievement:- Before starting the planking I gave the hull a coat of one part PVA one part water. I did this to seal the balsa and give a better foundation for gluing the planks. Once dry i gave the hull a light sanding to remove the raised nap Before starting I estimated the number of planks I needed. This turned out to be a bit disconcerting - circa 150 nearly all of which need to be shaped. I thought of the guy estimating the bricks for the great wall of China and decided that my task wasn't that bad after all. I started at the deck level with 2 parallel planks and then it was into tapering all 4 planks in each layer. The bulwark planks will be added once the hull planking is complete. At the stern I attached a "keel" plank as an abutment for the hull planks as they curve and twist towards the stern. `The slight curve at the rudder end of the keel plank was formed after soaking it in boiling waster for a couple of minutes. Because of the narrowness of the stern it didn't take many planks before the I was cutting the plank ends at a fine angle to abut the keel plank. The angle was established by laying the plank on the hull and marking the line with a fine razor saw. Where necessary the angle was corrected with a sanding stick. The plank transition on to the transom was roughly sanded - to be finished once the hull planking is complete. I also did a bit of light sanding of the hull planks to test that they were going to sand flush. I'm not sure why one plank is so dark - hope it will not be a problem later. 2 days progress looks small but inevitably progress was punctuated by drying interludes as each layer of planks dried - allowing the holding pins to be removed. Still a long way to go:-

At least the rudder is going to be simple to make.
