Darn good - no flat surfaces on scope or rifle required. Use the bubble to true the level of the assembled rifle/scope, then rotate the scope in the rings to match a vertical reference. I use a weighted string hanging off the washing line for that.

+1 The only correct method to set up a scope. Centres the scope vertical retical thru bore centre. Most other methods are good enough though for hunting rifles. Dialling up at long range will show up inaccuracies of mounting.

I too made one but eventually bought the Brownells version.

Once the scope is mounted I've also gone to bore sighting using a strong torch thru the ocular lens projected onto a plumb bob string line. With this method I can bore sight very accurately in the length of my gun room. I can also do the vertical travel check, winding the cross hair up and down the string.
