Re: Chainplate fabrication
We do a lot of replacement chainplates in titanium, and frankly I am with Nifty, I wouldn't replace them in a third world shop unless I knew for sure the quality of the material, and the workers. If someone accidentally swaps in 300 for 316, which is almost impossible to test for unless you have a moly test kit, you could be screwed.
The way we work is to have customers send us a tracing of their chainplates with dimensions marked, then we digitize that into a CAD program. From there it's off to the water jet cutters.
