size=2>There are a few frames of tubular steel, I am pretty sure that Taylors
designed one a while ago. It was built by a firm who specialised in the use of
tubular steel - free of charge from memory. I am sure ADH will be able to
confirm this.</FONT></DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial

size=2>Some modern H section framesides are also made of RHS (we
are installing one shortly at Preston by Weymouth - the lower
tier is H's). All box section has to be appropriately drilled for the
galvanizing process - so that it is galvanized on the inside surfaces
too.</FONT></DIV>

size=2>Is there really any evidence that steel headstocks are more likely to
fail due to fatigue? My personal view is that a headstock of galvanized
RHS</FONT><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000
size=2> which has been either powder coated or primed and painted, is belt
and braces above a cast iron stock from a corrosion point of view.</FONT></DIV>
<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000
size=2>There are heaps of steel headstocks from the early 20th Century that are
still doing good service, and in much better condition than some cast iron ones
that I have seen.</FONT></DIV>

<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000
size=2>I suppose that it mainly comes down to looks, cast iron looking much more
stylish than RHS - a bit of a Rolls Royce vs Ford Escort scenario - they both do
the same job, but one looks more stylish and costs a lot more!

<DIV><FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000
size=2>RHS is more robust than grey cast iron - I have lost count of the number
of stay sockets I have seen cracked or broken out, caused by improper fitting of
replacement stays..............."Oh one bolt will be enough Jim - we had better
get a move on, practice starts in 10 mins" and all that............</FONT></DIV>

size=2>The steel corrosion at Rosscarbery is the most extensive that I have
ever seen - I have kept some bits as souvenirs! However it was
only extensive where it was in direct line with the sea air (near the
windows), or in contact with the tower walls.</FONT></DIV>

evidence (as yet) to convince me otherwise.</FONT></DIV>
