[Public-List] Main Sail Track Fasetening

Mon Oct 19 18:17:52 PDT 2009

Roger,
Well there are 9 provinces for sure. Newfoundland, my native province, only
entered confederation in name and not in spirit. Dammed mainlanders trying
to steel our oil revenues!

Peter & Gord,

Golly, I have been using them for years and just called them square heads or
finish screws (the ones w/ small heads).  Most of the SS "deck" screws I use
instead of the cheap drywall screws have square heads.  Good to know the
correct name.

PS - Does Canada really have 10 provinces?

Hi Gord,
Yet another history lesson for our Yankee neighbours. Even the average
school kid here knows that a Robertson screw is the "square head".
With the price of the dollar approaching parity the Yanks should seriously
consider becoming our 11th province. They sail our Whitby boats, use our
Robertson screws; why not jump in with both feet.
That would make "Old King George sit up in his grave! 
Peter

Hi Roger... that thing about the Robertsons is only partly true.

The Roberston uses a genuine square recess.  You can put it on a driver
(hand or power) and it will stay there as you place the tip in position.  So
long as you use the right sized driver, they won't slip.  The Philips head
is  the horrible cross slot thing that slips like crazy and won't stay on a
driver.

The reference to Henry Ford is true... but there is a post script.   
Recognizing that the Robertson was a superior fastener, he specified  
them in his cars.  But, he wanted to buy out Mr Robertson's patent.   
This was something Robertson refused to do.  Ford set out to bankrupt him
and nearly did, but the company survived but never got over being driven
down (pun intended) by Ford.  Today they are little known outside Canada.  I
laughed like heck when I saw them starting to appear in Woodenboat Magazine
as 'new square-drive' screws.  I called the distributor to ask if these were
Robertsons.. they of course had never heard the name.

We did a documentary on the story a while back - it was a hard sell at first
but the twists and turns of the battle with Ford (who apparently was quite
spiteful) were better than fiction.
