Hohner Bass Part Repair

[boxplayer4000]

My picture shows the 12 bass note selector rods with operating levers and pallet lifting levers.(Click on the image to make it larger.) I believe some of the operating levers are becoming loose. I have read somewhere that the levers are attached by an electric welding process. If so I may need to come up with a different solution. The material is hard and ferrous. The rods are 2.5mm dia. and the levers are 1.75mm dia. If readers of this site have any information about repairs I would be grateful.

In the past when repairing an older box of some value and the repair parts have become obsolete or unavailable, I've had rods spot brazed. The Hohner parts you show here are not advisable to spot braze as their metal composition is of poor quality and spot brazing will affect their temper and any stress will cause them bend easily and it some cases break. Your best bet is to find a used box that's sold for parts only and replace the bass machine or scavenge it for parts.

Jim D: Thanks for your comments.
I'm not familiar with the process of 'spot brazing' but I will research it.
The accordion in question is a Hohner Morino 1, probably dated about 1938, and the quality associated with this name is already evident. The problem with this one is some drying out of wooden parts coupled with their distortion and the reason I have the bass dismantled is to access the wood sounding board and pallets etc.
Had the accordion been one of the 'atlantic' or 'verdi' range, for example, I think the chances of finding a spare part from a scrapped instrument would have been much better. If I lived in Germany or had the language I also think my chances would have been much better.

May I suggest that you approach your local model engineering society?
They are usually full of skilled, knowledgeable, people, used to tackling odd problems.
The Edinburg one seems a likely candidate and seems to meet weekly...

Many thanks for your helpful remarks. A local model railway club have been helpful in the past. I try to be independent as far as possible and exhaust possibilities before I pester them as they're not 'commercial' at all and efforts are voluntary. Where are we going to be when these skills disappear?
