Hello Derek,

Are you by any chance thinking of my Eilean Mòr thread from a few years back? If so, it is still here: **LINK**

Cheers,

Thread: 121 gun warships

Hi Stephen,

If I understand your post correctly, you want to scratch build a static model of a sailing man-o'war of the larger sort, i.e. a ship of the line from the 1700's (which, given your mention of the Victory, I suppose might inlcude the Napoleonic Wars era).

This would of course a pretty ambititious build, and I sincerely hope that lockdown will be but a long-past memory by the time you finish it, but there's nothing inherently impossible about it; where there's a will, there's a way.

Firstly, as most of the people (active) on this forum tend to be more interested in (a) more recent prototypes, and (b) the r/c side of the hobby, I suspect it might be worth your while for you to check out an American forum, called Model Ship World (see **LINK**) which, I believe, has a centre of interests much more in the direction you are looking at.

Then a quick search of the list of plans published by Brown, Son & Ferguson in Glasgow threw up a set of Harold A. Underhill plans for a c. 1813 74-gun two-decker (see **LINK**). Please note that the link is only to the first of a total of seven plans, so at £10 per plan, it is not exactly inexpensive stuff. On the other hand, it is a set of Underhill plans, and there were few better than Harold A. Underhill when it comes to plans (and he was a top-notch model builder, too), so likely to be worth the money if you want an ambitious build.

For even more money, there are also a number of publications available from SeaWatch Books in the US, that provide not only plans but also very detailed build descriptions by contemporary masters of this type of build, see **LINK**.

Finally, another possible source of plans is the Brunel Institute at the S/S Great Britain Museum in Bristol. They hold the David McGregor collection of more than 7,000 plans, a list of which is available on their website (see **LINK**). For a fee, they are happy and willing to provide scanned copies of most of those plans (exceptions may apply for very fragile material).

Good luck with your build,

Mattias

Hi Bob,

I remember reading in another book on another conflict (Peter Englund's book on the battle of Poltava in 1709, during the Great Nordic War, to be precise) that the main point of battlefield tactics and behaviour in the era before widespread use of precision, long range, high rate-of-fire and (not least) smokeless fire arms was not primarily to kill or maim as many as possible of the enemy, but rather to get them to break and run by the psychological pressure of a massed advance.

Furthermore, given the lack of workable means of communication, what with all the smoke and noise, dense grouping was pretty much the only way to keep units reasonably together, and may well have helped the individual withstand the fears involved.

In most cases, I think the casualty figures also make it clear that the precision and rate of fire was low enough that you usually stood a sufficiently decent chance of coming through alive and unhurt that the odds would not have seemed too long for those involved.

One my my big regrets from travelling in the US, also back in the 1990s, is that I did visit the battlefield at Gettysburg, but only stayed for about two hours. But I didn't know then what I do now, about neither the battle itself, nor how well-preserved the place is, and we had further to go that day, so basically only saw the museum and the view from the top of Cemetary Hill.

And if you haven't read Shelby Foote's three-volume work on the US Civil War, it is seriously recommended!

Hi Eddie,

That is absolutely true, and my wife and I are well aware of how fortunate we are; both able to work from home, a comfortable house with a lovely garden (and a nice workshop, too ) and on top of that the village bakery and pharmacy are still open for business, plus we live more or less at the nexus of a network of walking paths that take us straight out into the open countryside whenever we want a constitutional (which is expressly allowed under Belgian lockdown rules, as long as one keeps one's distance to anyone one happens to meet). Here are a couple of photos from a nice 6 mile walk we made last week:

And yes, we do indeed have a lovely dawn chorus! We get quite a number of birds in our garden, and this time of the year they're of course really at it!

I forgot to say about the charging and storage charging that the former was done at 1C, so that it took just over half an hour to get the battery up to full charge, while the discharging down to storage level was a rather slower process.

The max current setting for the Storage mode is 1.0A, which is what I selected, but the charger decided for itself to run the process at 0.5A, going down gradually to 0.2A for the final balancing act; that thus took neigh on three hours, but it was a lovely evening to sit reading out back, enjoying the garden, while the book I'm currently (re-)reading is thick enough, too, to last me rather longer than that, so all in all, no worries ...

Well!

Yesterday afternoon, the postman turned up with a nice, big package, that had taken a full week (!) to travel the +/- 14 miles (!!) from Albatros Modelbouw in Mechelen – but then I read in the paper yesterday that what with lockdowngenerated on-line ordering, the Post Office has to handle the same volumes now, week in, week out, as it usually only does in the run-up to Christmas (which might incidentally also explain why I've not yet recieved my copy of the May issue of MB).

In any case, there it was, and first out of the box was this beauty: a Robbe RO-Safety dedicated LiPo charging and storage box:

verktyg497.jpg

According to the specs it is good for simultaneus storage of up to the equivalent of two 6S 5,000 mAh packs, so my little 3S:er had plenty of elbowroom, all to itself.

verktyg498.jpg

For the details on the features and specs, see **LINK**. Obviously there's only one way to really know if it does what it says on the box (ha!), and I most sincerely hope I'll never find out, but in any case it is a pretty nice piece of kit. Rather more pricey than the usual soft LiPo bags, but I'm happy enough to have spent that on peace of mind.

Furthermore, there was a couple of packs of Z-Poxy finishing resin (and no, I don't expect to use all that on this build; I'm just stocking up, is all) ...

verktyg499.jpg

... and glassfiber cloth in 25 and 100 gram/m2 weight respectively.

verktyg503.jpg

I also recieved a receiver ...

verktyg500.jpg

... and a Hitec HS-81 servo.

verktyg501.jpg

After my days work was done (I'm still working full time from home), 'twas time to set uip out on the back terrace, and fully charge the LiPo, which went completely hassle free, I'äm delighted to say ...

verktyg504.jpg

... and then to bind the receiver, solder on a Deans plug on the powefr leads of the esc, connect it to the LiPo and set it up with the programming card (another doddle -- that card was well worth he money!) and finally test the motor-and-esc set-up.

Everything went swimmingly well: the motor runs nice and smooth, forwards and backwards, and is very quiet, too.

fhbygg9.jpg

All in all a very successful afternoon, which I then rounded off again, back out on the terrace, by running the storage mode (dis)charging programme on the LiPo, to take it back down to 3.8V per cell. As I won't be using it very much during next stages of the build, I figure it'll be better that way; it can still be used for any occasional testing needed, and then topped up every now and then back to said 3.8V/cell storage voltage.

verktyg505.jpg

A couple of things rather struck me during the charging and discharging process.

Firstly, the LiPo didn't increase its temperature in any way that could be detected by simple touch, which of course was reassuring.

Secondly, with the press of a few buttons, the charger very neatly displayed a lot of measurements, including current voltage per cell, which meant that progress was easy to follow, which in turn also felt very reassuring.

All in all, I rather think I've been getting me boxers in a little more of a twist over this whole LiPo thingummy than what was really necessary – but then again, I feel much happier with having been perhaps overly cautious than the opposite.

Hello Ray,

Yup, 'tis 35C – and as it happens the exact same brand and spec as the packs that Dave M. put into his two prototype boats a few years ago. So, there's precedent

Mattias

21/04/2020 10:29:03

Hi Ray,

Oh, I think I will continue to worry slightly and build that boat

And indeed things such as barbecues and fire places (both of which we have here at home) can cause fires (and probably do much more often than LiPo:s). Back in the 1980s, an aunt of mine made a very serious error: she'd enjoyed a cosy wood fire of an evening, and then, being (too) tidy, removed the (as she thought) burnt-out ashes before going to bed. The ashes she put in a plastic (!) bucket, which she then pushed under a chair in the entrance hall, intending to take it out to empty next morning. However, she woke up in the middle of the night (actually, the cat woke her up!), with flames coming up the stairs from the hall to the second floor, where she slept! She had to climb out through a window, and was lucky to survive! If it hadn't been for the cat, who knows how it might have ended?! The fire brigade managed to save the house, although it needed extensive repairs.

From which I learned (a) never to clean out the grate (or the barbecue, for that matter) on the same night as it was used, and (b) to use a proper, made-to-purpose steel ash can with a heavy lid and a bottom raised to two inches above the floor for storing (even cold) ashes until final disposal (on the compost heap, usually).

As for the balancing dervishes and all that, my charger does have a mode (called Charge) expressly for the purpose of charging LiPo:s without a balancing lead. But I'm not going to use that mode, am I now?!

Thanks again, though, for your encouraging words and kind help

Gareth,

Thank you very much, too!

Just to be clear, the manual does of course say that balance charging (i.e. using the Balance function) should be done with the lead; it also implies that the same goes for the Discharge function. It is just when it comes to the Storage function that the manual is really not clear at all.

Any road, 'tis balanced 'twill be!

Most emphatically THANKS!

Bob,

I'm sure a tin hat is much better than a tin foil one, eh wot wot?!?

That pile'll just be for storing the stuff. I plan to do all charging out of doors (there's a handy electric outlet on our back terrace) in a protective box on top of some fire bricks.

Thread: LiPo storage charging
21/04/2020 09:17:03

Here's one more newbie question on the by now slightly worn-thin subject of LiPo:s.

As mentioned already in my Sweet Sue II thread, I have a SkyRC e6650 multi-chemistry balance charger and am, since yesterday, also the (still ever so slightly apprahensive) owner of a brand new LiPo battery.

If for a moment we pretend that we've never heard owt about with what the road to hell is proverbially paved, I might perhaps dare say that I do at least wish to set out as a LiPo owner/user with the good intention of doing everything by the book.

This should of course include regular checking and (re)establishing of storage voltage, for which purpose I dare say the Storage function of the charger will be just the thing.

Now, I have read the manual of said charger backwards and forwards, and have also googled the matter, but have as yet not found a conclusive answer to this question: should storage charging be done with the balancing lead connected or not?

From the way certain passages in the manual are formulated I suspect that the answer is "yes", but I would very much appreciate any input you could provide!

Many thanks in advance

Mattias

Hello Ray,

Yes, they are indeed batteries, but at least to the novice user of them perhaps not quite as "only" as the ones with which one is already familiar, given all the dire warnings and strict injunctions with which they come. Of course I understand that manufacturers and sellers of something that could carry a risk must underline and to some extent exaggerate said risk, both to cover their own behinds and to make sure that users are aware.

In any case, yesterday afternoon, the chap from UPS brought me my package from ComponentShop (while maintaining appropriate distance, natch!), in which was first and foremost a LiPo (cue thunderclap and some menacing music) ...

verktyg490.jpg

... but also a LiPo guard bag (soon to be replaced, but more on that once the postman has been along today with a further parcel).

verktyg491.jpg

Here in Belgium, the DIY shops were allowed to reopen on Saturday, so yesterday afternoon I popped along to one and bought some fire-resistant bricks, of which here's a sample ...

verktyg492.jpg

... with which I created a sort of secure storage facility in a part of the garage (which is heated in winter, so always at room temperature) where there's nothing else immediately above or in front that wouldn't be able to survive the heat of an incident. I will make this neater with a small metal cabinet from Ikea, once they too are open for business again.

Am I being overly cautious here? I'm sure I am (if I weren't, I wouldn't have bought a LiPo in the first place), but I'd rather err with a very large margin on the side of safety – if nowt else it'll help me sleep at night!

verktyg493.jpg

And while we're being cautious, here's the low voltage alarm as already discussed

verktyg494.jpg

I also took the opportunity to stock up Deans type connectors, regular, mini and micro ...

verktyg495.jpg

... and finally there was the programming card for the ESC.

Good morning Gerard,

I just wanted to add that a similar question was asked on the forum a couple of years ago, and that a fairly extensive discussion of paints and painting techniques followed. Parts of those discussions were then continued in several other threads created by the member who had asked the initial question. You'll find them here ...

**LINK**

... and might perhaps glean some further useful information from them, not least as they also concerned the build of a Billing Boats kit (Bluenose II, as it happens).

Some of these threads are perhaps on the longish side, but I think looking through them might be worth your time.

Regards,

Good evening Gerard,

Given the size of the hull, which is certainly not huge but nevertheless reasonably large at just over half a metre long without the bowsprit, and the simple black-and-red colour scheme, and if you want to keep your options open, I'd say that automotive spray can paint (Halfords is a brand that I know is used by many modelers in the UK) wouldn't be a bad choice.

For the superstructure and other fittings topsides, I'd be more inclined to choose a dedicated model paint of some sort, and to apply it by brush. One could certainly spray can paint at least the larger items, like the deck houses, but personally I'd fond it easier to use a brush for everything but the hull. Humbrol enamels would be the traditional choice, and perfectly adequate, although for my part I do most of that sort of painting with Vallejo Model Color acrylics. It doesn't really matter very much which exact brand yiou choose. Just be sure that you don't get dedicated airbrush paint (e.g. Vallejo Model Air or most of the Tamiya paint range), as those tend to be too thin to brush on very well. And stick with model paint for anything small: the pigments are much more finely ground than in regular house paints, and so willcover much better with a much thinner coat.

Best of luck and much fun with your build!

Thread: Wooden model
16/04/2020 16:32:03

Hello Gerard,

I would say that there's no such thing as "best" paints; as with so many other things in this world, well ... it depends!

Apart from the question that you bring up yourself (static or sailing model), there's also the size of the model; whether you would prefer to apply the paint with a brush, an airbrush or from a spray can; and to what extent your are prepared/able to put up with the odours associated with solvent-based paints. Add to that personal preference ("I've always used Brand X" ) and ease of sourcing, and the permutations become (almost) legion.

However, the most important issue to my mind would still be whether or not the model is supposed to go on the water, and I'd say that this is something about which you need to make up your mind before you go much further. Not only because it'll have an influence on what paints would be suitable but because if you decide to convert a static kit to sailing (unless it is already expressly intended for sailing), there are a number of other issues that you will need to address.

In other words, could you perhaps tell us a but more about the model in question? Scale? Maker? Sold as suitable for display or for sailing? And what would you really prefer to do: build a static model, or a sailing one?

Mattias
