Very narrow bridge for a tap style instrument?

[Mr M]

I'm planning to build a tap style instrument and the string pitch will be 8 mm (like the Stick). Even the guitar bridges are bigger than this. Do you know any bridge/saddle that can be used?

I don't think Warr is selling their bridge, nor Stick and even if they do I'm sure it would cost an arm and leg. What would be your suggestion? Unfortunately I don't have the possibility to machine it by myself.

Krappy, they sell those bridges.
