Hi Gerry,
Dang! What a Mind Job they did on you..
What those sites failed to tell you is that they stole other peoples ideas and fed them into their own commercial interests. Home building is fun in itself leading to a great deal of self satisfaction and pride. Sure a build takes time.
Manufacturers have only one interest and that is Self interest and $$$$ Look about you at the Big Multi Nationals and their Advertising Tactics.. Need I say more?? Tightly close your fist hold it before your forehead extended to arms length and unfold your middle digit and fly the lying swine the "Bird"

Now go to "Construction" Look at the LLF Mini Plans, Run Off a Couple or so sets and then begin to collect the materials. You have more than enough Home Builders in Ireland to advise and may be assist. All you need is to be able to user your Head, Arms and Legs.

There also some very experienced builders here to advise you, although they will be off to the Champs' in Europe for a week or two..
Welcome back to the site and Happy Building..
Ron

PS; If I give you a hard time then it is for several reasons. You are out of range for physical contact, you may well deserve it but above all it is only in fun.. I have a copy of "Pukoon" and one just has to love the Irish..

And after reading comments on other sites saying that home build land yachts are not up to much as bought land yachts because they have years of testing and it was near impossible to get the geometry right for the sail and you would never have the same speed handling overall enjoyment as a bought land yacht.

I have proved to myself that the opposite is the case with LLF Minis and blokarts.

After joining Seabreeze Forum a few years back I lost all interest. My interest has been rekindled again.I Was going to purchase land yacht but could never seem to get the cash to buy as I always had to use the money somewhere else.

welcome to the forum, gerald.
dont be shy to ask any question, we have probably already made the mistakes and can tell you about it
I would disagree with nikrums statement thats manufacturers have stolen the ideas, its more a case of good ideas and bad being seen and picked up backwards and forwards. ofeten ideas come to people in different places at the same time.
If you looking for a starting point , the LLM is a great place to start, it will give you the basics of building and sailing, and you will be pleasantly suprised with the performance.
You wwill probably have to substitute materials, as some of the things we have you dont and visa versa. ( although all the stuff seems to be available in latvia!)
this come s back to the silly question bit
even better share the experience with a mate or your kids, by building a small fleet
cheers Paul

gerald1234 in answer to your questions...

1. Ground clearance .If you have 150mm ground clearance your wheels would need to be 300mm minimum diameter.
Often people use drop axles to lower the overall height of the yacht, this is done to lower the centre of gravity which makes the yacht more stable. To raise the yacht will raise the centre of gravity and it may more easily tip over. Why do you want the yacht higher?

2. Overall dimensions of land yacht .I would like to build compact design for easy transport .Can I build one that's is easily taken apart and put together again.
The LLMini will beak down and fit into the back of a hatch back car or station wagon. Mast pieces are normally the longest pieces.

3. Steel type round or box section.
Round tube is better for the main spine as it withstands torsional twisting better than square tube. Rear axles use square to stop them rotating when using the brake.

4. How to connect axle stubs .type of axle to use.
Normally its a weld in situation or a bolt through the axle and stub axle.

5. Weight. Does the overall weight affect performance .as to say if you over design the frame. Add hubs to axles. Steel wheels .Extra bracing
It is often said weight is only good for steam rollers but a few Kg extra is not a problem... but its normally not needed as the materials specified in the plans are a good balance between weight, strength, availability and buildability.

6. Sourcing all the materials

Keep in mind that the LLMini has been developed over MANY years and perhaps 100+ yachts picking the best parts and discarding things that don't work.... The yacht might look simple but a lot of time and effort has gone into getting the plans and yacht to the current point.

Seems to me Gerry, that you have all the knowledge at your finger tips and like me when I first started a build I needed a little friendly advice and a Pat on the Tushy to get me moving. The first thing you should do is to Print out the LLF Plans and sit down and redraw them ( I will be decried on this and asked WHY?)
Well what this will effectively do in my humble opinion will be to have you building your first LY in your minds eye. That is what I did with Occum's Razor, it really did slow my mind down and allowed me to understand what had to be done and when. It also boosted my confidence and gave me time to start gathering materials etc. Many years ago I took up Hang Gliding and as luck would have it I had a sheet Metal Factory at my finger tips and outside work hours I built a Seagull by shear Bloody Mindedness and a lot of help from those that had the experience. I had 7years of flying before Lifes Little Tricks took me out of the game.. Moral to the yarn is; Don't procrastinate any longer, get in there and do it and ask all the questions you like and I am sure you will find others in Ireland with the same passion who will be glad to help.
