I really want to build a 3v dome for festivals etc but I''m worried about building/designing the hubs myself. Is there anywhere I can buy ready made hubs? or are there some really good (and cheap!) plans available. I;ve seen the other thread but I''m not sure i can make much sense of it..

You could import them from the states but it certainly won`t be cheap. The current price for a commercial 3v 3/8 pvc hubset is $507.00,or around £250 excluding the shipping. Material wise thats probably £45 worth of pvc tube so not a bad profit margin really for cutting it into sections and drilling a few holes :)
Which part of the hub threads are you having trouble with?
Colin have you ever thought of making and selling hubs or kits yourself? It seems it would have a lot of interest.
I have built domes for people around the local and outlying areas but I only build them as a hobby pastime and not for making a living. The main problem is finding the time to do it..my own prototype dome project is still ongoing, luckily i`m not in a great rush to get it finished :) Timber domes are fairly bulky items to package and transport. Apart from the actual cost it isn`t good for the environment, especially when timber is so easy to obtain locally.
Haing said that I think Paul, the site owner, was looking into making dome kits available so he may be able to give you a progress report.
In a nutshell, if someone is really stuck i may consider making some hub kits etc but as there are many alternative methods of making them.. you`d have to be quite hopeless at diy to get into that position :)
HI there, where are teh ready made hubs from?..i have searched and yet cannot find anyone...caan you post a link please?
It all depends on which country you live in. Also on the type and size of dome you plan to build. The hubs need to match the size of timber used. Larger domes need stronger hubs due to the extra weight.
I am in the UK, going to build a 2v 5/8 dome, diameter 15ft.
May just take a week off at the end of the summer and do a project....ie make the ends, though if they do sell them i would like to see what they actually look like.
Thanks for the reply.
I`m also uk based. I`m not sure if your planning a 2v hemisphere or a 3v 5/8 but i guess its probably the latter. To make the most of our standard timber length (2.4m) and to minimise waste you may want to consider going a little smaller than 15ft diameter. By my calculations with a 3" hub the most efficient timber length for a 15ft 3v dome would be around 2.58m. You`d need 55 lengths for a 3v 5/8 but it pays to buy 60 to account for the inevitable dodgy ones.
