Sometimes saving a buck is important, and can be done safely. I had a prop drilled for a 3MM engine, and those holes (all but TWO) weren't even CLOSE to what I needed for the DL 50. So... a little hardwood dowel and thin CA work, plugged holes. DONE. Using a drill jig, and a proper drill press - I actually was successful redrilling, and it didn't throw the balance too far off. I'm confident of the hub integrity, and I've already run it successfully.

You can save a prop that's misdrilled, if you want to, and have the patience and materials.

Oh - it was a TBM with an over-drilled center hole, too. But I didn't notice initially, either..... [:@]
