How to crimp!..

 

CrimpingI had an email from a reader asking me about one of the links over here on the right hand sidebar under “Useful Info” – and it reminded me to look at some of my links again!…

One of the links that I just loved is from an author who goes by the handle “mainecrusing”. He has numerous “HowTo” pages here. There are lots of photos for each job and I have certainly found them very helpful – check out the one on crimping tools for example.

…”In this photo I have lined up some of my wire crimper’s. The one on the far left IS NOT A CRIMPER! I only say this because I have witnessed people putting together marine terminations with a pair of PLIERS!!

The next crimper, the one with the yellow handles, is a cheap hardware store quality crimper and should only ever be used in an absolute emergency.

The middle crimper is a decent quality Klein crimper though it’s not really well suited for much other than crimping non-insulated terminals. The fourth crimper is a good quality crimper, made by Ancor Products, and designed specifically for crimping marine or aviation grade heat shrink terminations. The jaws of this crimper are precision machined, and wide enough in cross section, to produce an excellent crimp. This crimper is also of the ratcheting type and will not release until a proper crimp has been made. The final crimper shown is another ratcheting type crimper but this one, set up with the jaws shown, is designed for insulated terminals. ….”

Mainecrusing also has a YouTube video channel although that appears to be of less help since he seems averse to actually speaking. He is obviously quite a guy – this link shows him replacing a diesel engine on his yacht – single handed!

On a related note to the “howto” of crimping is the issue of keeping joints clean and free of corrosion – perhaps one of the hundreds of connections that you didn’t do or that some “professional” did when the installed your chart plotter or radar …grrrr!

This is a list of techniques and products that you might consider:

  • Tin the wire – if you can access it and have enough spare wire to play with
  • Coat the joint with Vaseline or petroleum jelly – after cleaning the corrosion off with emery paper
  • Spray the joint with Conformal Coating – again, after cleaning if possible

Or use one of the combination grease + conductive materials type pastes :-

 

Wiring supplierFinally there are many obvious places to go to get electrical supplies – and many of us – me included have bought stuff in car accessory shops to save money. This eBay supplier – Genuinedealz – seems to have a lot of good feedback from people- they ship free in the USA and UPS to the UK.

Genuinedealz actually stock real marine grade parts, tinned wire, lugs, tools and is also a great place to compare the electrical properties of wire and accessories before you jump in and buy something.

Happy Crimping !

Routing 3 of 7: Data Inputs (wind, pressure, tide, streams, wave heights etc..)

There is a famous saying with computer software GIGO – garbage in garbage out.


So this review of software based routing calculations starts with the data that is being input.

There are 5 main sources of “data”:

  1. The expert assessments and factors stored in the software by the authors, and their expert consultants such as Michel Desjoyeaux
  2. The instruments on the boat itself feeding data in real – time
  3. The behaviour of the boat – its specific sailing characteristics – especially as represented by a polar diagram(s)
  4. The adjustments made by the skipper/navigator based on experience, or experiment.
  5. Data from external sources especially GRIB data.

It is this GRIB data that I will look at first.

Routing 2b of 7 : Routing planning and optimisation an extra brain as well as a pair of hands...

In my previous posting I listed those systems which were clearly aimed at the racing sailor. This is not meant to be a drawback – it depends what your objectives are as a sailor as well as your capability and skill level. They very accomplished pieces of software and provide at the very least a source of information to the cruising sailor about the higher art of race tactics, tuning and performance.


The next group are NOT inferior to the the first (TableA) in any way -  but I feel that they are less likely to be underutilised by the normal cruising sailor than the ones in the racing stable above. I feel that they may be operated in more of an amateur manner with less fine tuning than the top racing packages. This is a backhanded complmemnt to SeaPro and MaxSea – systems which are very well accomplished on the racing circuit !

It may seem strange to put MaxSea in this table since there are dozens of race wins attributed to it… but it is included as testament to the ease of use of its interface that I believe makes it more intuitive than the race packages above. It is truly a race class piece of software but it can easily be used by a cruising sailor with its elegant “TimeZero” interface.

Google provide another search vector

Google Labs is in the process of developing a new application called Google Fast Flip. It promises to give the user ‘a new reading experience that combines the best elements of print and online articles’ and one of the developers, Krishna Bharat, wants the public to give their feedback on the trial version that has just been launched.

Firstly, it is important to understand why Google Fast Flip was introduced in the first place. According to industry insiders it is to help resolve the conflict between an ailing newspaper industry and companies such as Google and Yahoo that aggregate content online. Apparently what is needed is to encourage people to read more news from actual news sites, and to do that, we need faster navigation of media-rich news content online.

A recent Senate hearing heard how Google have tried to resolve the issue through using living URLs to direct news searches to the relevant source.

Google FlipThe idea is that all news stories will be at a single updateable URL, and therefore easily found by anyone searching a story.

This will, in theory hand power back to journalists and those in the news industry; and combined with faster page navigation, it will feel like Google has donned the Santa hat. This all seems rather altruistic for a search company, and has therefore raised suspicion about the real reason behind Google Fast Flip….

I have tried it using the search term “Sailing” and it is very fast at bringing up dozens of publications and news stories in a much more attractive way than the normal search. So why don’t you add it to your bookmarks or iGoogle page and give it a try – click on the picture above…

Is it time we did not have to depend on the “Grace and Favour” of the US Coast Guard and Dep of Defence?

It is just over a year ago that, thanks to the feedback of the cruising community around the world, the future of HF radio services was saved!

You may recall that the U.S. Coast Guard’s issued a notice dated April 18, 2007, soliciting public comment on the need to continue providing high frequency (HF) radio broadcasts of weather forecasts and warnings via:

(1) Radiofacsimile;
(2) voice; and,
(3) Simplex Teletype Over Radio (SITOR)

This was issued by C.S. Johnson, JR.,Captain, U.S. Coast Guard, Acting Assistant Commandant for Command, Control, Communications, computers and Information Technology – well that is one powerful CIO job!.

The notice stated that in summary:

“…The Coast Guard is soliciting public comment on the need to continue providing high frequency (HF) radio broadcasts of weather forecasts and warnings. Public comment is necessary in order to assess the demand for the HF radio broadcasts of weather forecasts in each of three forms: (1) Radiofacsimile;(2) voice; and, (3) Simplex Teletype Over Radio (SITOR), also known as Narrow Band Direct Printing (NBDP).

The infrastructure necessary to provide these services has exceeded its USCG HFlife expectancy; the equipment is no longer manufactured, repairs are difficult to accomplish, and spare parts generally are not available. Because of the very significant costs involved to continue these specific HF radio services, the Coast Guard requires information on the extent to which these services are used by the public and what alternative services are being used or are available to obtain weather forecasts and warnings.
…”

Luckily after an outcry the US Coast Guard concluded that:

“The responding public collectively perceives that the USCG HF broadcasts are essential to their safety. There is no viable alternative to the USCG HF broadcasts because present alternatives are perceived by the public to be out of financial reach. Also, marine weather forecasts available through these alternative sources may not guarantee the same level of accuracy, timeliness, and/or sufficiency as provided by the USCG HF broadcasts…”

Should we not have a separate mandate for the sailing community that protects it’s interests on a formal basis rather than leave it to the discretion and judgement of professional staff who may have many other challenging objectives and other more powerful stakeholders to satisfy?

What about the US GPS network?…when will that run out of “grace and favour” ?
