I totally agree with your point about using loctite rather than over-tightening a set. It's a great way to ensure that the propeller stays in place without damaging the surrounding material. And I love the tip about using two. Also, thanks for the suggestion to buy smaller their from McMaster or the local hardware store to fill out our sets. That's a smart way to make sure we have all the screws we need for any project. Speaking of
screws, have you ever checked out Australia's No.1 online fastener suppliers? I'm interested to know what you think of them, as I'm going to be ordering soon.
