I just watched S7E25 "All Good Things ..." of Star Trek: The Next Generation which I believe is the final episode of the series. In this episode, Captain Beverly Picard tells the crew to pilot her medical ship into the Neutral Zone at Warp 13. In a separate episode of ST: Voyager (actual episode unknown to me), the characters Tom Paris and Harry Kim talk about not being able to break the Warp 10 barrier for some reason. This is toward the end of the series. Is there any explanation in the Star Trek Universe which explains this seeming difference? This especially confuses me because ST:V (1995-2001) started the year after ST:TNG ended (1987-1994). I would think it would be produced with these story lines in mind. Is there any explanation for this?


Question: Without using dowels, how do I join 2x4s edge to edge to be 1.5" x 7"?
Answer: I would definitely use Pocket-hole joinery

My brother got me a jig that is very easy to use, and the joints are incredibly strong even without wood glue; also if you use glue the joins are "self clamping".

Basically this allows you to edge-join, or do 45 degree angles, etc. just by drilling a couple of perfectly angled holes and screwing the pieces together such that the screw doesn't protrude from your work.

Obviously, I wouldn't get a jig for just one project, but I have totally stopped using dowels, biscuits, and other fancy techniques in favor of pocket holes.

Hope this helps!
