We had an urgent project that took all hands, and the blog wasn't updated for a month. I am sorry for that and hope to get back to regular updates.
The tonearm prototype is finally coming along nicely. The first armtube I've selected for testing is a 9.7 mm diameter thin wall (0.2 mm thickness) anodized aluminium.
I've started the measurements, but hit a totally unexpected problem. The wax refuses to hold on to raw aluminium! And using other glues make the results incomparable to the references we have. For the next post, I'll treat the surface and, hopefully, will have a solid set of vibration data. The first tests look promising!
