Not sure that I would want to mess about making something that takes the full force of the rear suspension. Would be fine in compression, but how would you insert the threat for strength in tension? A cut thread would be very weak and a rolled thread would be needed. You would also need to have a left hand thread in one end so that it is adjustable, just like the original.
I've decided to get the seat lowered first, Company called Viking quoted £75 (had one quote of £300+vat!!) so will see what comes back. BTW, Bob T - why would a cut thread be weak? Really appreciate the help and suggestions.
A question that would need a very long answer that I learned in all my years as a techie in the RAF. Perhaps Google will be able to explain it quicker than I could.
Still a little confused, after working as a CNC Precision Engineer for 20+years and cutting just about any thread that you could dream of (including custom pitched LH Threads )I always believed that the strength of a thread was relative to the pitch and thread depth - no matter how it is manufactured (obviously screw cutting gives you the widest scope) - you can, of course, turn down a Dia. or bore an oversize hole before threading to produce a weaker thread but that's by choice and not design?
I'm thinking you are referring to rolled threads as opposed to cut threads - a process very few are likely to have access to?
