    [Pedant Mode:] Unless they were made from an Al-Li or Al-Be (or metal-matrix composite, or similar exotic), the Brembo calipers would have the same stiffness in their materials properties as the...

    That was a feature, MM - it was so you could use a thicker rotor with the same caliper.

    :D

    Maybe it's time for clarification - you don't want to make a fastener, you want the stock to have the same relative strength as a Grade 8 bolt, right? It's correct that large -8 bolts are lower...

    I've thought of doing this, not for a direct replacement, but for some bespoke applications I have in mind. Some of the linear rail I buy has the "short pitch" spacing from the factory, but most is...

    It's got lower ductility than 17-4, 7% vs. 10%), and while that's not a huge difference it could matter depending on application.

    You might be better off really digging in and determining that it's definitely the linear rails before committing to reballing. Even if the rails look good, they may have uneven wear or minor...

    Also consider environmental effects. If your parts will be subjected to any corrosive elements (even just used outdoors), check out 17-4 stainless steel in a H1075 to 900 condition. But it's not...

    What I'm wondering about is the fretting damage (or whatever that is) on the surface of the live center Morse taper. That alone might have been a cause (or result?) of a poor fit to the tailstock,...

    I have to disagree. Plate has grain orientation from the rolling process, which means that you can get uneven stress relief as the bell is thermally and mechanically cycled. This can take the hub...

    It may be the specific batch of 303 that's being a pain - like 304, there's not a lot of tight control on the mix that leaves the mill, so you never know exactly what you're getting.

    Hey Scruffy,
