Re: back movement?
Use your common sence when using your doll,
If you think you are putting to much stress on her then you probly are and she will break!!!
We had a guy in here not to long ago who did just that and broke his doll.
Just be carefull

Re: back movement?
Why can't they get consistent torque in their joints?
My B2 had some joints so tight I literally had to put all my weight on them to move them (neck joint). It freaked me out but it was only after I called Abyss and spoke to their engineer that I was told I might have to do that to move her neck back. Ditto for the forearms. You can barely rotate (supinate/pronate) without using all your power to turn them. Then there's others (like wrists) which become floppy in a few months.
It confounds the fug out of me why such a beautiful doll would have continual problems in this area.
Qualifier: I haven't bought a new RD since 2008 so not sure of any improvements in this area.

That's because sculpters are not engineers, they use the other half of the brain.Zarnon wrote:This is something that's aggravated me about Abyss since I've been buying their dolls.

It's why my photos don't have the beauty of Stacy's: Different side of the brain!

Zarnon, I think this is a case of Abyss not having a verified engineering procedure for consistent torquing of skeleton bolts - I wonder if anyone there has heard of a torque wrench..... Also, there is a basic problem with any bolted joint that is subject to motion: bolts are great at holding together assembled parts AS LONG AS THEY DO NOT MOVE. The problem is that moving the joints works at the bolts and WILL eventually loosen them, as moving the parts overcomes the friction holding the bolts tight. The ONLY way you can prevent this is to prevent the bolt from turning and thus loosening. This is in fact possible and CHEAP to do. I sent both Abyss and Lovable Dolls information on keeping the bolts tight and a list of hardware that would do the trick. The cost per doll was at most $5-6 for the hardware. I don't remember hearing anything from Abyss, though they did thank me for the email I sent. But I don't know if they are using this, or any other idea to maintain bolt torque. I did get a nice note back from Matt K. and Bronwen stating that they were looking at ways to stabilize LD joints, and that they'd look at what I sent them. The reason RD joints are so tight is that they have to overtighten the bolts to keep the joints from loosening right away. As was mentioned, I don't know at all if the RD2s use a different system, but over-tight joints increase the strain on skeleton parts and can lead to broken "bones". As it happens, the information I sent was intended to improve RD joints, with their interleaved design. I know that LD and now Sinthetics seem to have fewer problems with premature joint loosening. Beyond that, I am an interested amateur......

Re: back movement?
may be RD's offer the possibility to move the back. Last year I had to repair a broken spine tube (look at Realdoll care and repair). It's better to make the spine screw very tight, otherwise you get an ugly stomach pleat. This ugly stomach pleat will stay.

Re: back movement?
I think this is the "back joint" that some have had replaced with a hime. From this joint to the shoulders is one solid piece.
