I use different tunings very often and this construction did not work properly. I remembered to have an easy-tuning classic guitar with Rubner machines and they are equipped with ball bearings!! |
These ball bearings are surprisingly cheap and very effective. |
It takes some courage to work with this drill on the guitar if you have to work free-hand. |
The inside 6 and outside 10 mm ball bearings fit exactly the axles of the Schaller machines. |
The first attempt for a slide bushing. I made at least 4 different ones but they all did not work well. I must build a better one before I go to work on my 12strings.. |
Yoe need a slide bushing because the dril will "dance" in the hole without it. I later used another one which was much longer. |
The first drilling hole gave me the courage to try the rest. |
On the first attempt I forgot to fill the drilling hole in order to give the drill a center but fortunaltely it worked well. |
Looks nice, nearly invisible. |
Completed. Works perfectly. | | |
