Trigger issues
CYA friends:
Here's a picture of a B&A trigger installed in a custom RFBR action.
The arrow on the left, points to the sharp upper edge, corner, of the angled engagement surface of the transfer bar.
Here's an issue that can develop because of that sharp edge:
IF, this sharp corner of the angled engagement surface does all of the holding of the cocking piece when the action is at battery, over time this sharp corner can gut a groove in the cocking piece.
When this happens, the cocking piece will sometimes fail to override the transfer bar when the trigger is pulled.
The cocking piece will be held by that sharp corner and will not override the transfer bar.
By the way, this can happen with the Jewel, FF and B&A triggers.
CYA friends, the Remington pattern trigger is the best target trigger design ever.
CYA friends, the Remington pattern trigger is the worst target trigger design ever.
Either way, we're stuck trying to deal with it after all these years.

If the relationship between the angled engagement surfaces of the cocking piece and transfer bar, in your contraption, are such, that the sharp top corner of the transfer bar does all of the restraining of the cocking piece when at battery, you will at some point, most likely, have failures to fire when the trigger is pulled.
