Coming from a machinst and 3D design background, your "OD" dimension pointing to the "ID" if your groove is misleading. Is the 4.351" the inside of the groove or the outer diameter?

Other than that, it looks good.
 
Is your groove flat bottomed or round bottomed? I don't see any detail on your groove other than .036" depth. No geometry shown. I've never ringed so I'm sure that might be a given....but not on the dwg. Is it a flat bottom bit or a .120 full radius round bottom bit?
 
Yeah I know I should have pointed it to the outside but it was easier that way but that's why I wrote "outside diameter" I can see it being miss leading tho.

I have not decided yet which cutter I want used so that's why I didn't list flat or radius.

Sent with a Droid RAZR in one hand and 14,000 volts in the other.
 
A .105 ring is typically .034-.036 deep with a .120 radius tool and .032-.034 with a flat bottom and a stock cummins gasket thickness. As drawn it should say I.D. and the proper diameter depends on your fire ring size.

If you decide to go with a radius groove you should dimension to the centerline of the ring which is 4.455" in your case. If you dimension to the I.D. like you have it the diameter will be off a bit because the .120 groove isn't deep enough to actually create a 4.350 I.D. If you go with a square groove then 4.350 should be your I.D.
