As with current margin rules, all short sales must be done in a margin account. If you sell short and then buy to cover on the same day, it is considered a day trade. Does the rule apply to day-trading options? Yes. The day-trading margin rule applies to day trading in any security, including options. What is a pattern day trader?
This is completely normal and is seen on $300+ Benchmade custom balisongs (tang pins deform or pivot screws back out). On a balisong with screw construction, LocTite is used to hold the pins in place. On FHMs, I use industrial strength epoxy.
The loctite line is pretty good but I still think that hobby class cyanoacrylate glues (super glues) are better because you can buy them in many different formulias, sizes, and even one toughened by rubber, which makes it less brittle. If you have a hobby shop near by check out the selection.
