Re: Chainplate fabrication
For someting as simple as the chainplates you should be able to judge the shop and the workers for yourself. If you are worried about the steel, you might want to see the plate before the steel is cut and polished. The plate that the chainplates are fabricated from should be marked with the alloy, the manufacturer, and the heat number. The shop should have a "mill sheet" (analysis) for the heat (batch of metal). If the shop does not have it, the manufacturer should be able to fax it to you. The mill itself should be ISO 9000 certified which means that a competent third party (usually British Standards Institute) has examined their quality control systems and they can be trusted.
