Pics of the disaster please




Or it didn't happen.........

Bummer Ron.... Maybe pics of what broke, and where/why?

that looks like a case of......... neglect......nickypoos [}:)]

Probably but not having reinforced the base section plus the gusty conditions didn't help a lot either.

Ah Well! Live and Learn.

Yeah John,
That'd be right and I'll bet that if you were a sailor of Yesteryear you would be the Boatswain with the "Salt" and Cat-o-Nine Tails..[}:)]

Now you've Salted the Wounds are you happy.
Ron

And well you deserve a few strokes of the cat. Internally that mast step is as rough as your humour.

No wonder the mast said "Bugger you. I'm going on holidays."

I know you can do better than that Ron but it is probably just the result of a stent in the works that caused your momentary lapse into Shelby Wright practices.

Many wind surfer masts have an aluminium tube about 500mm long that fits inside the mast bottom, with evenly spaced through holes and some kind of collar by which they adjust mast height and/or luff tension.

I have one of those shoved up the bottom section of my three piece mast with a marking on the outside of the mast where it comes up to and it is held in by epoxy glue or silicone (forget which). Then I have a hardwood bung about 150mm long shoved up the ally tube.

After that I have a split length of 50mm PVC drain pipe fastened to the mast base with pk screws to shield and cushion the brittle fibreglass from direct contact with the steel mast step. When rigging the split is always positioned at the front.

My mast is much like me. The bottom section is heavy, the mid section is substantial and the top section has bugger all in it.

I hope you find that information useful.

Edit:- This pic is what I started with which is three w/s masts that I got from the dump for about $20 and a fibreglass radio mast that I used for joiner sleeves and the two ally base tubes with adjustment collars.



The mast on the right with the repair near the top is what I used for the actual mast and one of the other two I used for the boom and joiner sleeves reinforced internally by offcuts from the radio mast.

There was a lot of sanding involved and shoving tapered sections inside other tapered sections until the right amount of overlap was achieved.

The eventual length of the mast as I recall is 4.7 m.

This pic shows the PVC drain pipe protruding past the mast step and just below the gooseneck, the mark of where the ally reinforcing tube comes to.

Sheeted hard and resultantly down hauled, the tack of the sail comes below that point so I believe the mast will stand the punishment.

That puts me in mind of a Dear but sadly Departed Mate who used to say to me "Hey Pete. Let's take your yacht out for a sail and see what we can break." I loved the guy and really miss him.

Johm,
At this point I will say "Open yer bleedin' eyes Lad. Yer likely to crash"
That Metal Rod is a bolt attached to which is a piece of pipe (No No No.. Not a Peace Pipe)[}:)] which has 2 nuts welded to it fitted over the bolt. This allows the section of pipe to pivot with the flexing of the mast. When under way the Mast does not touch the Mast Step other than at the very base so that it can flex freely.

Good idea though, I just beat you to the punch. But it does show that you Yanks can think Jees! I kill me.
Ron

PS: The main problem was a lack of reinforcing in the bottom 500-750mm of the base. The CF is only 2mm wall thickness. Entirely my own oversight.

Big Motorbike, you are sooooo lucky. Any closer an I'd slap yer bloody silly........... If that is possible.
Ron

Yes OM. A small amount.
I have just picked up my re-cut fast sail, the pic's below are it. I would value any comment on its form. I removed around 400mm from the top Tapered 0 to 25mm to tighten the top Leech area.
I also removed about 2.5mtrs from the Luff area and this is how it forms now.. For Chook, the new PAd.









Ron

That sail looks really good to me Should be a quick strong wind sail
Will it take more downhaul to pull those wrinkles out?

Those wrinkles are almost always caused by not enough downhaul.

Looking at that I'd be giving it heaps more, at least 1.5-2cm more than it's got at the moment.

It looks a wicked sail Give that downhaul death!!!!

tie off the FRONT of the mast pocket to the front of your rowlock , that is the source of all those wrinkles.
THEN give it some downhaul
PS that sail is gonna hurt[}:)][}:)][}:)][}:)]
probably needs to be 200mm back on the mast too, but tis not possible.
whatever you do , when it lifts a wheel dont sheet out more than a few mm
yes mm
particularly downwind

Looks great Ron.

I assume most of the recut was on the luff and foot.

Could you please post the sail's luff, leech and foot measurements and the draught or offset measurement of the luff.

With the luff pocket at the base as you have it, racing measurement rules would surely put it out of "official" races but I know that does not corcern you.

I recently scored a 9.5 m mono film sail with battens and cams on which I want to do a recut.

I will post a pic or two and hopefully the "brains trust" here will have useful recommendations for it.

Cisco,
There was no alteration to the foot, only the lower2/3rd of the Luff and the Top 400mm to tighten the sail overall.

I wouldn't know where to begin with those measurements. So you had best Draw me a Mud Map.
Oh! By the way that was an 11sqm Speed Sail from a Wind Surfer.
Ron

AWWWWWWW, nickypoos you must have been in a big willy willy or a bit of a spin

we saw the tracks where you had been, temporaly, you must have touched down

breifly , just north of Woomera, wheeltracks indicate this happened!

....Your a ledgend

Well well well! She Speaks again[}:)]
TP1,
Yes! You could be right but I prefer to think I am at the other end of the body, Hip, Torso, Head, BRAIN[}:)] However for your good self I'd not go so high maybe just below the Hips and too the left or right of whichever leg is appropriate [}:)] You know that Dangley little thing that just hangs there being useless to you these days. Maybe you use it to water the Sturt's Desert Pea
Ron.
PS How are things over that way??
