Ill be happy to help you out when Ive finished my machine. The problem is i don't have a great deal of spare time at the moment so any i do have, id like to get my machine finished first. Hopefully, that won't be too long. Id be happy to send you the drawings if you need them now.

I got it from a bloke called Phil at Metallin. Nice guy and you can order small quantities and pay with PayPal.

Had a look at their website. As far as I can see there's no catalogue with mechanical data in it so hard to compare their extrusions with KJNs, also not entirely sure how their fastening works, seems you have to do some drilling? or did you use the corner fastenings with covers, and are they rigid enough (e.g. non-swivel as KJN make a distinction here)?

Thanks for the PM... seems the answer is 'no more than whats on the website'. The profile is similar enough I think to the KJN one to use the I values from there, and the E, well I'll assume 6000 series Alloy; should be good enough. Still not clear how the corner fastenings work though.

Jon did you manage to send those files? Just checking incase my mail is not working. Cheers buddy

Sorry mate, I got tied up last night so ill send it now. All the technical data you can find on the valuframe website, I just ordered from metallin because the order process for valuframe was so damn complicated, lengthy and theres a £100 minimum spend AND they need a business address to ship to....phew!. It's exactly the same stuff though. I did have to do some drilling, I mainly used the standard connectors(m6) and am going to fabricate a few straight brackets. Basically you have to tap the ends of the profile, then slide in the slot connector and drill a 6mm hole through the other side of the connecting profile to tighten it.
