Hello Bassic Karma
Thankyou for your reply. I did not give much information did I!
I had a request from a bass maker to produce titanium spikes.
The size is non standard at 16mm and 20mm diameter. The 16mm will probably turn out to be the optimum.
This thickness of bar is large but the weight is not too bad.
How this material benefits and enhances the tonal qualities of a bass I do not know. This area is notoriously unscientific.
However this guy is sufficiently convinced and I am by the same token curious to test the theory.
I produce cello endpins with a traditional steel spike. Carbon fibre has become very popular. It is very light and stiff but some feedback I got was that it seemed to dampen resonance.
I would be wary to compare cello and bass as they have different levels of vibration. It is only a gut feeling but my opinion is a metallic spike is better.
The standard 10mm spike looks very skinny by comparison and the reason for such large diameter titanium is to reduce vibration in the bar.
I hope this has not become too wordy and has made some sense. If you are able to give me any ideas or opinions that would be very helpful as I am feeling my way on this project.
