Re: Finger wire repair
The fingers can be bend in 3 dimensions, just like you want.
Is there any option to remove the existing (double twisted?) copper wires from all the fingers while carefully separating the TPE skin with a small screwdriver?
Best would be to use an all new wire from the finger tip down to the plate (flatten tube). I'm sure in a hardware store you find some usable stuff and perhaps you can make a 'bending test'.
When you start to solder on these existing enamel covered copper wires they will become more prone to break and it's a mess to do.
These screw in wire connectors shown by Mondoon could do it when crimped, it's easier to do as soldering. Copper is a good heat conductor and it can melt/burn the thin TPE layer so take care.

Samara, I have already drilled out most of the polyester putty from the flattened palm tube. (see photos). I know for a fact it is polyester from the smell. Its basically Bondo, car body putty. That will be the easy part. I will also put a loop at the ends to help keep them anchored in there. The big problem still remaining is to extend the existing broken wires in the fingers.

Re: Finger wire repair
On another note this is my hand inside of a yl 148 hand.
I think sometimes people underestimate the strength of this material it's much like an egg it has its strengths in certain directions anyways food for thought

Re: Finger wire repair
Very nice design! Very similar to what I have in mind as well. Using pieces of shrinktubes along the fingers with some additional "bone" inserted. I'm just currently brainstorming on if there is some better cheap alternative to the actual wires. Several fingers on my 140-doll are broken now so I'm considering to fix it, and also improve the functionality and overall quality while at it. Maybe even inspire some actual manufacturers to abandon the horrible wires once and for all. I'm going through boxes of electronic "trash" right now that I use for computers and such. Working on a list of things to buy when things are more clear.siliconefun wrote:Thanks carver. As said it's rather a simple design and I will try it on my 4woods lady as soon the finger wires will broke.

I've been looking a bit on designs of soldering stations lately. Maybe they could at least provide some parts to use, like the mini ball-joints.

here's a mod I've done on a 145 cm silicone doll from a mate. This is a one year old 'test stand' I created and today I still carefully bend the 'artificial finger' without any failure.

Nice!
I also wonder if something like this soldered/welded to the end of the
wires would help with the poking issues..

Re: Finger wire repair
here're the finger construction details related to my from post from May 30th 2017 http://dollforum.com/forum/viewtopic.ph ... 4#p1108954 On version 1 it can happen that the 2.0 mm O.D. brass tube as well the 3.0 mm O.D. brass tube can move which is not good. On version 2 I secured the 2.0 mm O.D. brass tube by soldering it onto the galvanized wire as well the 3.0 mm O.D. tube is secured by soldering so they stay more fixed in place as on the version 1 construct.
The inner 2.0 mm O.D. tube is 2 mm shorter in length as the outer 3.0 mm O.D. tube to allow a softer bending curve.
Version 1 is easier to built but I would rather recommend the version 2 construct. - SF -

Re: Finger wire repair
An alternative is to replace the copper twisted wires with Home Depot twist ties which are rubber coated wires with plastic caps. Can get two fingers per tie, and they come in a variety of diameters. They are very easy to position and provide a good option. Let me know if you folks see any flaws in my simple plan.

Re: Finger wire repair
I'm not sure I understand the distinction being made by abracadabra about snapping vs. tearing. I don't see as it is helping me understand what happened or why, or how to fix it, but I am wondering if some clue is in here somewhere?
My doll is brand new, even now only two months old, and the fingers broke very early on - before I'd had much chance to bend them at all, let alone ... uh ... tear them? But they sure look... snapped.
I've read a lot in this thread about heat and materials and solutions, and loved Seattle Slew's thread about ideas for new design, but that still leaves me with Cinnamon's broken fingers. I got in there and attempted a fix with spade terminals that is yielding some very mild results but nothing to jump up and down about.
dolljack44 I am particularly interested in your Home Depot Twist Tie concept - how would you attach those to the palm plate?

Re: Finger wire repair
This is still in the theory stage, but the plan, as described above, is to attach the existing finger twisted wires or the twist ties to finishing nails embedded in freshly replaced Bondo (car body repair filler) or JB Weld in the palm plate(tube) using simple crimped electrical wire connectors of appropriate size and wrapped with gauze as a cushion to mimic the feeling of tendon tissue. It appears that only the first three fingers of my YL148 and OR156 dolls were attached to the end of the palm tube. The thumb and little finger seem to emerge out of the sides of the tube. I assume that this procedure will apply here also, with a little finishing nail bending. As stated, this is just an idea extending the suggestions of others at this point, using materials available at Home Depot, and I welcome constructive criticism.

Well, I opened her palm to find the interior was not what I was expecting, though reasonably close. It seems they've done away with the metal coils/springs and just extended the copper wires into the palm plate.

Re: Finger wire repair
I will keep you appraised and may have pictures / video (not so good with the video yet, lack a suitable tripod) in a couple weeks. I have some serious epoxy on order and got a video from WM Doll (thanks to SRSD!) showing how to replace fingers. Like you said, the thumb and pinky seem to be on the "sides" of the plate, and interestingly both pinky fingers are still attached and pose easily though both thumbs and all three "end" fingers on both hands have broken.dolljack44 wrote:

Anyway, once this epoxy stuff shows up (I probably could have found some in town but I was about to leave on a trip and I'm an Amazon Prime junkie) I will probably see if I can get the wire ties to work. One question: if the ties are made of rubber, will that affect the TPE? I am going to get a package to see what the chemicals are. See if it's a silicone, or latex, or if it's actually tpe like so many things are now!
