Carbon propshaft for CSR

[David.Ashley.Poole]

My CSR 260 propshaft has a resonance period on the overrun around 80-90 or so.  I talked to Phil at R&R since I thought that it was my 6 speed... and he said it was the propshaft, and he was right.  It does it in any of the top three gears. So I thought that a lightweight carbon propshaft would push the frequency up out of the operational range, and it would have excellent damping qualities too.  I saw one on sale on eBay but missed it, and I was wondering if anyone had (i) had one made, (ii) mechanical drawings or specifications that I could use to get one made up or (iii) an old one that I could borrow as a template.  Or (iv) any other ideas or comments.  The UJs are not loose... but I might change them anyway and see if they made a difference.  Perhaps I can find some lightweight UJs.

The late Richard Lee used to offer carbon propshafts at about £850 ... but that was around ten years ago. Not aware of a supplier these days. Try getting yours balanced with new UJs.

CTG at Banbury oxfordshire use to make torqueline ones.

You could try them, still in Banbury bit now UTC and tight next to the M40 AND Prodrivre.

An old visitor to this parish had his prop filled with expanding foam - pretty sure it was Bailey Morris that did the work.

Queue expanding foam and canoe thread resurrection :-)
