That is excellent, I hadn't seen this but found it while looking to post about 3D printing.

Fantastic.   

Great news in getting the IVA.  You'll soon be driving it.

Looks good, enjoy.

Seeing your pictures and reading your blog take me back almost 12 months when my kit arrived on the 12.12.2013.  I am sat here with a massive grin on my face just thinking about all the fun I had building the car and scratching my head.  Just sorry that the weather doesn't look up to much tomorrow otherwise I would be out in it.  I look forward to your posts and all the best with the build.

Hi Alan, I did edit the text of the gear box oil change rather than add a new post, perhaps I should ahve done that instead to make the results more obvious.  

Anyway, the change in oil made no difference at all to overun noise in 4th gear.  Equally however I can't feel any difference in changing gear.  I was worried that the gear changes would be stiffer but it is fine.  All in all (IMHO), both oils function the same in the type 9 gearbox.

Not sure where the body text is when starting a blog post but this seems ok - http://caterhamsevenbuild.blogspot.co.uk/
