Confirmed to be a Ampair 100 with a date of manufacture between 1985-1990. I have been in contact with the company called Seamap and it's Singapore
division which is responsible for Ampair equipment
. Cost of new blades will be about $300 in total which includes price
The price is especially high when considering age and the other components that need to be removed, inspected and possibly replaced. I was sent a little history
brochure about Ampair which provides an interesting view of their products and development. I have attached the brochure.
I am now in the process of obtaining any service
documents for the Ampair 100. Removal
of the rotor and the disassembly of the slip joint for inspection
is needed. It is possible that bearings need replacing for the rotor. The brushes
for the slip joint could also need replacements
The rectifier assembly is another area I have requested test documentation
for. Not sure I will get anything for that though.
In all so far, it appears that blade replacement would not be worth the effort even if the other components turn out to be in good order.
I have been researching the repair of the existing blades. The blades were injection molded using glass reinforced polypropylene. This material is very difficult for repair bonding. It becomes more of a challenge given the condition of the blades. I have not found any proven repair method for the glass reinforced polypropylene. I have been considering and continue to review an alternative reconstructive method that will use the existing blades as a core
for an exterior coating. I still have some work
to do on this method. The cost would be about $50 for all 6 blades. Hopefully this will turn out to be a workable option.
If I solve the blade issue, I will probably put new bearings in. Hopefully the bearings turn out to be something standard.
That's it for now....... Henry
