Sorry, have been bizy making a new set of wheels (26") for someone. he only had 18"wheels. (for his class 5). Had a good sail the other weekend. top speed of 86.4Km/hr. Was good to get back on the sand. My yacht is going very very well.
havent broken anything. (touch wood). Me and the family are looking at moving
to Aus. (QLD)(yes will be bring all my landyacht stuff).

OK AD! so the Kiwi's lose is our gain by the sound of it, mind you you'd probably be better off (Land Yacht wise) in Western Australia Nice big Salt PAns to sail
Ron

Cheers boys. The sail is a windward sail. Made in Auckland NZ.
I was not happy with only 5 batterns in sail. I have had three more batterns put in and done some more tuning. It is going alot better. I have also made another carbon pod and two more y frames and one steering head. Also have made double landyacht. (have it up to 71km/hr with two up). Will try and find some photos.

Double yacht with class 5 specs.

It just a double one of these.
And comes apart very easy. held together with two pins.

Andy, you make sure you bring all that stuff with you when you come across the trench.

When googling for tyres 2 weeks ago i came across some 20x3.0 tyres called electra fatty-o's.As they were on clearance for $17 I bought 2.
the theory I was testing was that a 20" flat20/50 rim would give me a wider tyre without increasing the diameter too much. I could then fit a wider wheel into my existing front fork without having to make a new fork.
as a comparison I put a maxxis20x2.25 on a 32 and a 50mm rim to see the difference. all the measurements were with 45psi pressure.
the result was that the 50mm rim had slightly less diameter(4mm) but an increase in width of 6mm. the significant difference was that the wider rim has a less rounded sidewall, and that resulted in a stiffer tyre that would work as a back wheel. vindisdad has dug out a 20" rim from his class5 used at the '87 worlds and tells me it was 75mm wide, and a 2.25, the widest available at the time fitted fine.
heres the 2 tyres together


the 20x3.0 tyres arrived today and i was busting to fit one and see the difference.
the result was that I definitely wont fit this baby into my front fork its a monster!!!!!!!. what was noticable was the lack of side resistance. this tyre will defintely need a 75mm rim if used as a rear tyre.






i reckon it would be a cracker front wheel on a 5 over the rough and soft of walyungup, but probably not a performance improver on lefroy on the front..... .
I think i will be saving this one for a bike project or put it away for the day when super-super minis come into their own.
.
. well

the construction sequence ive been using gives you a self aligning wheeel.
accuracy of say +/_ 2mm/
the mold disk is flat with a central 10mm hole and the nylon plug which will create the bearing housing and hold the aluminium centre spacer also has a 10mm hole .
the outer rim of the mold has been marked with a scored groove and with the new flat mold I simply hammer in a small nail at each spot where the spokes will go.
these locations are checked before glassing commences.

heres the mold disk . I will take a photo for you with the nylon mold insert and nails fitted.
the sequence of bulding is to lay up a first disk , which is the removed from the mold and put aside, then lay up a second disk , with the ally centre spacer attached. whilst still wet, a film of resin/cotton flock mix is pasted onto one surface of the rim, and then the rim is added to the mold.
THEN the rim is glassed into place
next the spokes have glass/flock pasted on the 2 flat surfaces,and are placed in the mold, some extra glass/flock around where the spokes meet the hub, and then glass/flock on the top surface of the rim
the first disk that was layed up is then pressed onto the rim /hub layup , a board place d on top and the whole shebang clamped down,
walk away and have a beer.
my little brain has been thinking about how an old bearing could be used to make a mold for the wheel , meaming that a nylon bush wouldnt be needed, so that may be my next little experiment

Paul,
Isn't the Nylon Bushing a Pufteenth smaller than the Bearings that fit into the final Rim, To create a slight interference fit??

I would imagine that an old bearing thoroughly cleaned and waxed with Bees Wax would release relatively easily with a little heat?? No??

I just don't feel right using Glass/Resin as a bearing holder.. Why can't an Alloy Hub Be glassed in to give a snugger fit?? I know under hard conditions Alloy can hammer out of round so why not Glass chip and shatter??
Ron

PS; What is with the editing of p o o f as in "Up in a **** of smoke??

That's fair enough then aus230.. It is odd how a person can get something stuck in mind and can't leave go of it, like a dog with a tasty bone.

One of these days I will build up the courage to " 'av a go."
Ron

Im taking photos of EVERY step to post as a lesson

That is fantastic, as I'm struggling to get my head round it as well.

A "wheel making 101", will be a big hit.

I follow this with great interest.

PS. What size rims do I need to round up to have ready.

Thanks, Chook

Because the saying is actually "Up in a puff of smoke!", you p**f

I am having a go at making some new 26" wheels that hope will be a very easy way to build them.
these to discs had from allow tread plate (that i laying around). These instead of
making fibreglass discs. will put progress photos as I go. hope to have wheel finished in a week.

Thanks for that Lachy, in the future if I feel the need to remark on PAuls Wheel thread I will PM him.. I am a bit of a reactionary and go with my immediate urges and I am getting a bit long in the tooth for change..

Nikrums post from the Flat rim build thread

Brilliant Paul,
I would suggest that if you even Fart you should post a pic' as it may have an integral use in later models (You know what I mean!) Keep to sequence and follow Desert Yanks method of Pictorial Explanation. This then should have a direct Link Post-it-note at the head of the page.
So when is the Big Exit Day for you?? (Europe)
Ron

Just did a little shift to allow the build thread to form as intended, a simple to follow procedure free of any distractions. Any questions/comments/discussions can be done outside that thread (at least until its run its course)
