Sorry Again Mike

You've lost me again.

For clarification- When I don't follow something I try to isolate something specific so that I know at least something that is on solid ground- so the area of discussion of any of my posts on this thread - in principle - would ignore the larger context of Matthew's graphic/theory and just isolate one concept that I'm trying to understand.

Sounds like some interesting stuff- but I'm a little burnt- here's a section of my post#34 in this thread
Tell me we're not going to have a "engineer guided thread" - you know the kind that take 200 posts to get to the point! (West Coast LOL)-

Hey, it's probably just me but I could see it coming. I'll just finish off by saying "Looks like some great stuff. Graphics are great compared to anything I could do, but could be better with some shading etc. to show the plane relationships. It'd be nice if you could explain it so I could understand it- but maybe that's an issue with the reader (me) and not the writer. I'll check in every once in awhile on the thread and get caught up to date with any of your new discussions."

I didn't realize which post you had responded to... sorry about that chief(in my best Maxwell Smart voice)But hey, look at it this way... we've got 60 more posts to get to the point.

Thats it!
That's the solution!

The cone of silence.
We need to raise the cone of silence, then we can hear each other!

You've gone and done it now. If we get the cone of slience out now, we'll never get to 200 posts...darn it all:eyes:

A little humor just at the right time- nicely done Golf2much!:)

We need to look at the relationship of the right forearm and the motion it makes in relation to the inclined plane in the right elbow bend plane which dictate the wrist conditions.

Heres a graphic.

Now lets define this - regardless of anatomical restrictions

- If the plane of the elbow bend is onplane (pics - row 2)

a)bend and arch wrist motion is onplane with a level wrist throughout when the hand is vertical to the inclined plane (90 degrees turned from elbow bend plane)

b) cock and uncock motion is onplane with a flat wrist when the palm faces the inclined plane (0 degrees from elbow bend plane).

- If the plane of the elbow bend is directly vertical to the inclined plane (pics - row 1)

a) if the hand is vertical to the inclined plane(0 degrees from elbow bend plane), the onplane motion is that of bending and arching, the right forearm motion becomes uncocking (r forearm below plane) and cocking (r forearm above plane)

b) Also if the palm is directly facing the topside of the inclined plane (90 degrees rolled from elbow bend plane) then the cocking and uncocking motions are onplane as the wrist would arch (r forearm below plane) and bend (r forearm above plane)

c) If the palm is facing the underside (90 degrees turned from elbow bend plane) then the bend and arch are reversed from b) but still with the cocking and uncocking motions onplane.

- If the plane of the elbow bend is 45 degrees into the inclined plane (pics - row 3)

a) If the wrist is vertical to the inclined plane (45 degrees turned from elbow bend plane), the onplane motion is that of bending and arching and the right forearm motion becomes uncocking (r forearm below plane) and cocking (r forearm above plane). However the right forearm motion will also change the relationship to the onplane motion in the degree of bend or arch.

b) If the palm is on the topside of the inclined plane (45 degrees rolled from elbow bend plane) then the onplane motion is that of cocking and uncocking and the right forearm motion becomes arching (r.forearm below plane) and bending (r.forearm above plane). Again the right forearm motion will also change the relationship to the onplane motion - cock and uncock.

- If the plane of the elbow bend is 45 degrees into the inclined plane (pics - row 4)

a) If the wrist is vertical to the inclined plane (45 degrees rolled from elbow bend plane), the onplane motion is that of bending and arching and the right forearm motion becomes uncocking (r forearm below plane) and cocking (r forearm above plane). However the right forearm motion will also change the relationship to the onplane motion in the degree of bend or arch.

b) If the palm is on the underside of the inclined plane (45 degrees turned from elbow bend plane) then the onplane motion is that of cocking and uncocking and the right forearm motion becomes bending (r.forearm below plane) and arching (r.forearm above plane). Again the right forearm motion will also change the relationship to the onplane motion - cock and uncock.

This has been a wee bit tricky to type out so if made any errors please correct :)

Darn it Bagger... see what you've gone and done now. Brought out the cone of silence and no more posts. Matthew better get busy or we'll all be smoking cold turkey.

A great summary of why elbow location is so important.

Cool Mathew, thanks for putting that together and for all the outstanding graphics you've been posting. Cheers - :occasion: - EdZ

I just stopped because there didn't seem to be too much interest anymore in the thread. I'll do another post soon :)

No lack of interest here

Anxiously awaiting your next installment. Your last post was so detailed and thorough that there wasn't much to debate. Try leaving out a few critical details and watch the fur fly!!!

Thanks for all you help, the 3D graphics are very helpful in helping me cement my understanding of the various motions and interactions.
