A Google search of fibreglass gets 1000 hits and a search of fiberglass gets 41,000 hits. Also, I notice that this window underlines fibreglass as misspelled!

Is fibre a British spelling? I cannot reliably spell much of anything so spell checkers are my life line to credibility!
"fibre" is the way it's spelled in many countries. "fiber" is the USA way (and some others).

"fiberglass" is the USA way (and others). In UK (and other) countries it's "GRP" for glass reinforced plastic(?).

Just wish the rest of the world would "get it together" and spell things correctly (see quote below):

"The European Commission has just announced an agreement whereby English will be the official language of the European Union rather than German, which was the other possibility.
"As part of the negotiations, the British Government conceded that English spelling had some room for improvement and has accepted a 5- year phase-in plan that would become known as 'Euro-English'.
"In the first year, "s" will replace the soft "c". Sertainly, this will make the sivil servants jump with joy. The hard "c" will be dropped in favour of "k". This should klear up konfusion, and keyboards kan have one less letter. There will be growing publik enthusiasm in the sekond
year when the troublesome "ph" will be replaced with "f". This will make words like fotograf 20% shorter.
"In the 3rd year, publik akseptanse of the new spelling kanbe expekted to reach the stage where more komplikated changes are possible.
"Governments will enkourage the removal of double letters which have always ben a deterent to akurate speling.
"Also, al wil agre that the horibl mes of the silent "e" in the languag is disgrasful and it should go away.
"By the 4th yer people wil be reseptiv to steps such as replasing "th" with "z" and "w" with "v".
"During ze fifz yer, ze unesesary "o" kanbe dropd from vords kontaining "ou" and after ziz fifz yer, ve vil hav a reil sensibl riten styl.
"Zer vil be no mor trubl or difikultis and evrivun vil find it ezi tu understand ech oza. Ze drem of a united urop vil finali kum tru.
"Und efter ze fifz yer, ve vil al be speking German like zey vunted in ze forst plas."

On Frøya I use a spark arrestor made from a house hold sieve. I can hardly press a 1 mm drill through the holes.

See the SBA web site photo album from the Silkeborg Firework Regatta last year - then you will also be forces to see that we actually do a little steam boating here in DK – (OK Gudmund were here to help us ;) )

In my wife’s opinion there are still too many particles, but they do not burn holes in the green nylon umbrella anymore!

We just get them in the eyes, and have to wash them away from everywhere in the evening.

I also exhaust in the chimney most of the time (that’s basically what generates the problem) but even when condensating, I do not experience any noticeably difference on the draft, compared to before.

I have tried a flat sieve on the top, but it will clog with particles. The arrestor must have a certain height to allow the flue gas to escape. Mine is approx 5 cm.

Best regards

I looked more closely at the material and it is not plain ole canvas it has a slick underside for waterproofing. I suppose it might get holey after a while but that might give it an interesting look. I could point out how lucky the passengers were to have the top.

I will put a screen in the top of the stack first.

Thanks
