You know, what's that great line from the movie?

Something like: "You don't understand, it doesn;t feel pain or pity or remorse, and it absouloutely will not stop, ever....."

.....until I have collected every piece of 4x4 useful tech info in the world in one place.

Added some cool new pdf files that are great for printing out and posting on the shop walls.

BTW - anyone know what the heck the "double depth" of a screw thread is?

I didn't see what context it was used in, but I would guess that they are referring to having effective threads that are twice the diameter of the fastener in question.

Nice work! Lots of useful info there.

Thanks

hello Bill,

happy to see you're back in bussiness!
that means that you are using your eyes again, which is great.

i was really shocked reading your post about your eye
injury, especially when it happened the same time i got two
of my fingers chewed by a cruel Warn 8274:(

i posted about it then, but i guess you just could'nt read it;)
well, actually i guess i had the same problem with you - i wanted to keep my fingers crossed for you, but could'nt..:)

with all that stuff you gathered, you got my coming
weekends full :beer:

Black Dog is correct.

I've never heard it refered to in quite that way before. But it is infered to be 2x the major diameter of the thread in depth. Just a safe depth for securing a bolt or stud. Any thing more is useless.

BTW, glad to hear the eye surgury went well. Hope it keeps improving.:beer:

Double depth refers to the depth of thread called by the difference in diameter rather than Radius. Dont make me draw a picture.

OK, I understand now . . . You threw me off when you said radius. Double depth is defined as the difference between the Major and Minor diameters.

Dividing 1.227 by the number of threads per inch will give you the Double Depth of a Unified National threaded fastener.

Double depth is defined as the difference between the Major and Minor diameters.

Right on!

Crikey Stephen....that's going to keep me busy for a while - thanks !

Froggy - yea, awful to hear about your accident too - I wish you all the best, and take care!

The eye's coming along well....3 more weeks recovery before we start investigating corrective measures, but it's looking good.

Still can't touch a tool for at least 3 more weeks - Just try not going in the shop for 6 weeks and see if'n it don't make ya crazy!

bgreen - thanks for the pic! worth a thousand as they say.

Thank you, very useful!
Just imagine the projects you'll be tackling when you're finally set loose in your shop! :eek: God help us all.
Hang in there.

I stand corrected.

I'll go re-read my Machinery's Handbook.:(
