You should probably round off the edges of the lock ring, as a further preventative to discourage removal- although if you ever DO decide to remove it, you should de-spoke your wheel first so you have absolutely no leverage.

Actually, you will find out in a hurry if your wheel will work. My only concern is that what you think might be tight using a hammer and screwdriver may not be so tight in the real world. That all said- I have a wheel with just loctite- no JB Weld and no lock ring- but best of all- no problems.
