Hi Chris ....(I assume it's Chris?)
Thanks for the post and details - prices your suggesting are more to my liking!. Actually I bought a length of 6mm threaded rod around 12 months ago when I was thinking of designing something myself, however thought the life of it would be quite limited - or the associated nut (which I would make out of some material like acetyl rod) would also be limited, so never pursued the idea further. I then started investigating ACME leadscrew and then ballscrews etc, so thus my comments re price etc. I assume Rockcliff are using threaded rod in their design?.
I still don't have access to the downloaded plans, although I had a phone call from Rockcliff this afternoon with password etc, which unfortunately didn't do the trick - a further download of files necessary on my part I think. (30MB file on dialup will have to happen overnight, tonight).
Full marks to Rockcliff however for making contact and support they have offered me. From where I stand that's great customer service - something I don't see too often these days. Hopefully I'll be reviewing the plans tomorrow.
By the way I'm in Wellington - actually Lower Hutt.
(Still learning how to post mesages etc to cnczone forums, so if this post incorrectly apologies to all).
Cheers
Richard

The steel shafting you can get from fletcher steel (Tube and steel) for not too much. You're looking for 'centerless ground rod', there are a couple of grades of the stuff, 4143 I think is the harder one they sell, can't remmember off the to of my head. Call their 0800 from the white pages and they'll quote you over the phone.
