heres the spring clips I was talking about. they are a riley product. I used to buy them in bags of 10 straight from the factory, they are cheap so when you parts shopping buy a handful( or a bag). they are perfect in 30mm
and would be fine in 35 but 40 would be starting to stretch the usefulness.
you can see the locking bolt I use to get a firm finish.
Those clips look like the go, i can't believe i didn't think of that, (like most good ideas)
Just thinking, would using square or rectangular sections be better for a Y frame. I can see there is a fairly large turning force to be dealt with, and i would think a square section would deal with this better.
I would stick with the square. round tenssile tube would be better,but we are starting to drift from the simplecheap available ethos with the yacht.
(ok yes i may be a leader in that, but Im lucky in my material availability.)
sorry ive never mentioned the little poppers before, I didnt want to complicate a simple design
Thanks to everyone for all the talk thats gone on over the last week. Lots of good info for the builders out there
OK Lachlan, I blame you for this.
So i pottering around the shed, I've got two mini chassis on the go, (new one for me and one for a mate!). I'm looking around the shed at the 25NB Medium wall pipe, (34OD x 3.5WT) I've pretty much convinced myself that the Y frame idea would be heavier than the standard LLM design. But hey i'll just weld some of this stuff together and have a look. Well it weighs about 6kg at this point. It'll need some bracing to stiffen it up but it might be alright. I can jump on it at this point withour too much flex. The Overall dimensions are about the same as a LLM.
Now what to do? I'll have to finish the LLM chassis i've started......Don't I?
is it upside down or is that an OTT
challenge yourself by keeping it in the LLM wheelbase, rather than taking the easy way out and making it longer and or wider
so far the outside dimensions are the same as a llm.
This is the right way up, however at the highest point it is only about 90mm off the ground. I was considering the idea of Iand's by putting the split under the knees. The only reason for not making it flat is by adding some triangulation, i can support it better with bracing. Hopefully weld this in on the weekend.
There is no way i am not building this is there?
I didn't want to start a new thread just for this but I have made up a little video clip showing some of last weeks sailing while I was away camping. Hope you enjoy it, and I apologise for the music in advance (it is one of youtube's (less obnoxious) songs to get around copyright issues). Beware this is mobile phone footage
Lachlan always be aware of your sheet rope dragging along behind you. If it gets under your wheel you may suddenly find yourself goiong in an unexpected direction i.e. tipped over as it will jam under the wheel ripping it from your hands and damaging the rope. A good idea is to tie the free end to your seat belt, that way if you inadvetantly let it go, it will be easy to find.
Also I noticed in this video that the foot of you sail was quite 'baggy' as the boom seemed too short. A longer boom would allow more outhaul giving you a flatter sail and a bit more speed and we all like a bit more speed
im really impressed that youve found a sailing site , considering all the rains last summer, and it looks great!!!!!!
Thanks for the advice. I was making an effort to keep track of the sheet rope while sailing, not let it drag behind but sometimes Im having too much fun to notice. Never thought of tying it to the seatbelt though, seems obvious now.
The sailing site, and surrounding claypans, are the high spots in the area so long term flooding isn't an issue. We had 22mm of rain last Wednesday and I was out on the pan sailing again on Friday (the weather was sunny and 35 degrees).
Unfortunately we couldn't drive across to check out the larger claypans to the west due to the rain. The one I was on is in the centre of the second of my pics ( www.seabreeze.com.au/forums/Land-Yacht-Sailing/General/Goggle-Earthlandyacht-locations/ ) Next time...
And didn't get away totally unscathed
Yep, no worries about the repair. What I appear to have discovered is a need to rough up the ply a bit more before glassing. To continue sailing I just screwed it back together.
The place is approx. 3.5 hour drive north from Bendigo. I'm sure someone could get there quicker but we don't like to rush it (have to make the traditional 'paddle pop' breaks). It'll be very interesting to check out the large claypan as the one I was on is only good for mini abuse. The property is a sheep station and camping has never been an issue/problem (the owner is a good fella).
There's even a goat or two running around the property to put in the camp oven
Nice footage Lachy but I would suggest a good sand back after glueing and coat both inner and outer with Glass Cloth and also take a little off of the front under your heels,
Ron
Humpty Dumpty! I don't crash that much and this is only its first breakage, give me a break [}:)] Plus, it will all go back together again
Thanks Ron. Yes, I will do a bit of sanding and glass the outside of the seams. There a still a couple of things to get right with the seat before I would totally glass it (for one; everytime I flip over the seat scoops a shovelfull of dirt into the seat). Next time...
Also, what do you mean by "...also take a little off of the front under your heels..."? Not sure what your getting at (yes, again ).
Glenn- I was wondering how you will attach the rear sheet pulley. Will you extend the frame or build the seat strong enough to mount to the back of seat
Ian
OK! Lachy,
I have your attention??Hmm? I was watching your footage and noted the closeness to the ground of your seat bottom at the very front, it would appear to almost brush the ground under rougher conditions. Giver that your heels do not come all the way forward to that bottom cnr ( It is hard to see exactly how it is designed) I reckon you could lose about a 50mm chamfer there and not effect your space inside and save ripping the seat apart on a rock or tree root. Just a thought Bud, I had to do that on Occum's Razor shortly after it's launch.
Ron
reason I asked Glenn, was when I was considering a class 5 it's one of the things that attracted me to the FED 5 vs the pacific magic-the frame didn't have to be extended for the sheeting, less of the seat is unsupported,having a flatter Y, in general the FED 5 excited me more than the Pacific Magic, these reasons plus mid boom sheeting is why I suggested a design larger than a LL mini might be an interesting design
Ian
I was being sincere. The Y frame mini talk is all good, I was hijacking a bit by posting my video and then talking about it with others. I didn't think you were hijacking.
