I hope this is not seen as advertising, especially as I am in a very remote place.
People praise the Vito 7212, but I consider the plastic Yamaha to be superior in significant ways. Just one reason is that I have worked on quite a few broken 7212s, but only one Yamaha, even though Yamahas are much more common here.
Part of the cost of replacement of a joint is that it is usual for significant fitting work to be needed to transfer the keys to the new section.
I have developed a method to deal with these breaks, which involves gluing, with the reinforcement of 6 or 7 stainless steel pins, about 40 mm long and 1.2 mm diameter, inserted into the wall of plastic across the break. The result exhibits almost no evidence.
With significant experience now, this routine takes me about 1 to 1 1/2 hours, and has been extremely reliable for the approximately 50 times I have carried it out over the last 15 years. I have repaired tenons this way, and then later had the same instrument come back the next time it has been sat on, to repair the corresponding socket, the same way.
It seems that this produces a result that is much stronger than the original, and no transfer of keys is necessary.
I have a copy of fairly detailed instructions if you can find a cooperative, more capable than average, well-equipped, innovative, interested repairer to carry them out.
What is broken, a tenon joint, its socket, or the body itself?
