I might have an extra set, I’ll have to look. They can be welded using 356. My cousin doesn’t like weldig them, but I’m older! All the CV corners I’ve sold are originals that have been repaired, I’ve never reproduced any. The parts I reproduced were in 535 Almag (marine aluminum alloy). But unless you live on the ocean, these original parts are fine with a polish and wax.
I’m just about to head out flying for a while, but I’ll check and see what I have. In the middle of completely rebuilding a CVX-17 bowcap that came to me in 4 pieces so I have to check on how that’s coming at the shop, too. The 17/metric bowcap was different than the other CVX caps so a repair was a must.
