Can someone give me a couple key facts about gods and events in N...?

Oh good grief The Vanir are not the "older" gods. They are a tribe much as the Aesir and they got into a war and traded hostages. Frigga is not queen and Odin is not a king and Loki is NOT Thor's brother. If ANYTHING (and the link...

Couple tattoo-- lock and key.. who should get which??

Well, if you want to go with the strictly sexual implications of the tattoo, then he should get the key (the "male" one of the two) and you should get the lock. I doubt I have to explain more on that tip. However. I love the idea ...

Crusader454/Borg Warner pinned shaft question

Q: I have pinned shafts in my boat. It has solid couplings with the key in the keyway. I had a 1 inch piece of the pin shear and go flying across the engine room. Need to get the rest out and replace with new. I need tips and ideas on how to get the rest of the pin out. I was told not to disconnect the coupling from the tranny or I'll be aligning the engine. I have a 5lb maul and some drift pins. Also, what holds the pin in? It had electric tape wrapped around the coupler.. but that cant be it..can it?Is this something I can/should do in the water? If so, do I check alignment of the coupling face and tranny before bolting it together? If I do need to realign the engine, how big of a job is that? Somebody told me 8 hours.

A: If your in the water-you will need to secure the prop shaft so it will not leave the packing gland and let the boat sink. I know it doesn't sound likely, but that's boating for you. The pins should be a press fit. many put a hose clamp over them so they don't fly when they fracture but then you don't know if they are failing till after the fact. I have only aligned Velvet drive but would guess its quite similar. I think 8 hours is a little long for an engine alignment. It should be real close to alignment or the drive pins would be the least of your problems. The previous post was accurate. ps- would be careful with that big hammer around those big Monel shafts-that stuff is pretty malleable. You don't want to skip rope after you are done-use a special press made just for such a problem. Wish I had a big boat with these problems!
