Anyone know where I can get an economical 1/2" spot face bit? Need it to spot face gasket surfaces for the needle seat of Q jet carbs (soft metal).

Von,
What size would the pilot diameter need to be? Spot face cutters (also known as counterbores) use a pilot stub in the hole in order to cut a true face. See tool on far right in pic below.
I can make one up when I return to work. Also, any radius on the edge of the spot face? Often there is...

Bill, You have a PM.

Looked at pilot point drill bits?

I don't think they will work for my purpose.
