Stripped threads on tablesaw arbor bolt holes. Repair how?

Have a competent machine shop look at the problem and suggest the repair.

Done.

Probable fixes are to fill the hole with threaded rod and re-tap or to install helicoil inserts. Have a machine shop do them. Preferably one where most of the guys look to have showered recently. Neither will be cheap. Either will be cheaper than buying a new table top.

It's a lunch-time fix but I would probably charge him $10 a hole. Bridgeport. Clamps. Indicator. Gage pin(s) to locate the holes. Drill. Tap. Helicoil. Needing to eat my baloney sandwich when the boss wasn't looking. Yeah ... about $10 a hole. ;-)

Thanks to all responders. The holes were repaired with heli-coils for a cost of $25 which consider a deal. I feel comfortable with the folks at the shop and am glad to have found a new resource for this kind of work.
