Yes, you should be able to press a BB86 bb into a frame with a home made press, much like you would with a headset.

As for compatibility, not all BB86 bb's are the same, like other bottom bracket standards, BB86 requires that you match the bottom bracket to the crankset you want to use. Example, there are GXP-compatible BB86 bb's for use with GXP cranksets, Shimano BB86 bb's for use with Shimano Hollowtech II cranksets, etc.
