Sephonia goes under the knife (Finger replacement + various)
Sephonia goes under the knife (Finger replacement + various)
A small incision was made where the hand plate ends. Broken fingers can be pulled out, then the intact fingers were cut at the base and also removed. They'd break soon anyway, so might as well replace them with a more durable option while I'm in there.
I'm going to be trying to free up the epoxy from the plate to remove the whole thing, drilling the right hand got messy so I'd like to avoid that.
Layout to determine replacement finger size.
Sephonia has been on the operating table for a week now (I haven't been able to work on her everyday) and it is killing me being apart from her and seeing her in this state I've also been working on sealing up the tears in her feet around the standing foot pegs, a puncture in her leg I assume from my dog putting a paw on her (the only other pointy thing that's been near her wouldn't have done that ), a piece of nipple that nearly flaked off, vaginal tearing, and various abrasions. I don't know if I'm going to detail/post about all of those things, but I will be showing the hand operation up to the final sealing/smoothing of the incision.
Well, I better get back to her so that the epoxy can set up in her left hand overnight. I'm using 5min quickset epoxy, so I have to work fast once I mix it to fill the hand plate and insert the replacement fingers. It still needs a day to fully cure, even though it starts to set-up and hold the pieces together quickly. Missing my snuggles, and hoping I patch her up acceptably. I think I need a drink... This is rough
Re: Sephonia goes under the knife (Finger replacement + vari
To determine how long to cut the finger wires, I cut some stubs from my replacement wire and inserted them into the hand plate. With all wires down as far as they'd go, I taped them together, with the tape flush to the end of the hand plate.
Now I could use this as a reference. Where the old fingers were cut was extended from the hand plate about a 1/4", as the factory epoxy oozed out that much.
I stripped a little insulation from the end of the wire to go into the hand plate, for the epoxy to better lock it in place, and wiped them all down with some rubbing alcohol to degrease them.
Epoxy was mixed and filled into the hand plate, wires are now inserted. You can spot in the background the nipple I had to work on. Not too shabby from a distance, eh? It's a little larger than the other one as I added some (perhaps too much) filler to correct it going out of round after heat-treating it to re-adhere the flake. It's not perfect, could maybe use some more work but I might just leave it for now.
Well, all there is to do now is have a much needed beer and wait for the epoxy to cure. Hopefully I can get to putting her fingers back into the hand tomorrow and seal her up. Once that's done, she can come off the operating table and back to the bedroom

In the manufacture of wire, there are curves of 6" diameter or more even for fine gauge wire in the path it takes through the wire drawing process.
These curves are not practical in a doll hand but Arthur1960 has come close with the softer Permatex adhesive

Thanks Mr. Ducati, your support and well wishes are much appreciated through this procedure. I'm learning as I go, I only became a doll owner 4 months ago, and really didn't expect to have to get into repairs like this so soon, even though I understood it was kinda inevitable. There is no way I'd kick my sweet Sephonia to the curb, she deserves a good long life in the best health I can provide for her, so here I dive headfirst into the unknown.Mr_Ducati wrote:GREAT thread Mau5! I really appreciate you walking us through this procedure. We hope everything ends will with Sephonia and she's good as new! Take care!
Mr. Ducati
@Arthur, I picked up several good ideas for how to perform this operation from your posts Your work inspired me, I went from "Oh no, I'm screwed" to "Hey, I think I might actually be able to do this!". You have a good idea with the silicone sealant, that little bit of give will help buffer against some sharp bends. Ultimately, if the bend is extreme enough, the wire will bend back sharply around the hand plate no matter what. It's a real engineering challenge for these fingers. They have to be stiff enough to hold a shape and hold some weight for props, yet flexible enough to bend, and malleable enough to do it repeatedly without failure. What material can fulfill all of these requirements? Rubber core would take all the bends you throw at it, but it won't hold a position. Solid wire (as is currently used) is just terrible because it breaks after several extreme bends, it really shouldn't have even been considered. I think we'd be better off with fingers that we couldn't pose, but didn't break from bending, while a real solution is developed.
I didn't have much time to work on her tonight since I had to stay a little late at work. I got her left hand sealed up, and the fingers at least inserted into the right hand plus clean up of the mess drilling made on her right hand. Thankfully, her right hand cleaned up pretty well just wiping with baby oil. Here is the left hand after the wires were inserted. I used scissors to make the incision, whereas on the right hand I put tension on the TPE and sliced it with a scalpel. I think the scalpel cut compresses back together much better than the scissor cut.
In it's resting state, the TPE wants to spread apart.
It pressed together neatly, so I figured a good bond could be made.
I put a small strip of filler into the bottom of the incision and bonded it with a soldering iron. I could have used more, and built up thin strips to the top of the incision. I had to add a few more filler pieces of TPE as the joint cratered a little. I just worked in a small piece at a time until I was satisfied that the joint was filled appropriately.
All sealed up! I haven't done any finishing/smoothing work yet, just not enough time tonight.
Here's how I went about inserting the wires (demonstrated on the right hand). I lubed a Q-Tip with vaseline and swabbed each finger channel in the hand, plus the wire. I curled the wires at the base, and started working them into their finger channels. I have no way to describe it, other than you just have to "feel" and finagle it into place while being careful not to poke it out the side of the hand/finger. The wire has to be straightened as it goes into place.
Right hand cleaned up and in resting position. You can see how the scalpel cut comes together very nicely.
Well, tomorrow is another day. This job takes time, and you don't wan't to rush these things.

Re: Sephonia goes under the knife (Finger replacement + vari
To facilitate the high temperature rating of said wire.
If my suspicions are correct, then that might (in part) explain the TPE degradation as noted in one of Arthur1960's posts.
As I said I'm not here to piss in anyone's cornflakes... Just putting it out there.
Cheers.
Re: Sephonia goes under the knife (Finger replacement + vari
Thank you, sir. My pleasure to post pics et all, "If it saves just one doll" I appreciate the tip about over-oiling, would hate to have gone through all this just to ruin the TPE. All said and done I will later post a review of my work detailing what I liked about it, what I didn't, and what I'd do differently if I had to do it again.Arthur1960 wrote:Hi again, great work, the repair looks impressive and I'm glad I was able to help a bit with my work last year. I like some of the different things you have done and the way you inserted the new wires looks to have been a little less traumatic than the way I did it! One thing I will say, after doing this a few times is that you have to be careful not to use too much oil on the fingers and in fact most of the hand. Of course you need to use it for preparation and when smoothing with heat etc but it's a good idea to use it sparingly and wipe away excess where possible. As the tpe is at its thinnest on the hand and fingers it can weaken significantly if over oiled, after doing the work you can improve things by powdering the area well and maybe slipping some cotton or lace gloves on the hand for a while. I've found that with care the tpe can recover but there does come a point when it's structure just looses integrity and will become too soft. I've seen others post about this in recent months so I now avoid oiling the hands just dab a tiny bit of vaseline in-between fingers now and then. Thanks for posting the pics as these help so much when folk are planning to do this themselves, Cheers!
Thanks Jimmy, I'll need to catch up on your Alyssa thread. If you do half as good at surgery as you do photography, Alyssa will be just fineJimmy_71 wrote:Very impressive Mau5.

Aww shucks... I ain't never done this before. No worries man, I'm new here and just didn't have any context for the comment. I was part thinking "Have there been a bunch of newbs that posted about how they wrecked their dolls, and it's like 'oh, here's another "surgeon"'. Then on the other hand, to receive praises before the job is even finished and I've got no history of repair work, kinda like, well, a tad premature. I wasn't professing myself to be a doll surgeon going into this, just showing what I'm doing is all. Dr. Nick was my attempt to bring some humour into the thread, this whole operation has been weighing heavy on my heart. Funny enough, I somewhat resemble Dr. Nick, what with the wispy moustache, goatee, and medium hair I kinda liked this meme for the theme of this project, tooseagull wrote:Mau5:

The repair work in sealing up the incision gets me tipping my hat to you
Speaking as a Journeyman Electrician who started in the trade 15 years ago, silicone in wire insulation is not common. One might only see that in specialty applications such as industrial machine wiring in a forge. Temp ratings of typical wire are 75-90C, and are jacketed with PVC or nylon, usually. The stuff I used was rated to 85C. That's really not that high of a rating, think about silicone oven mitts where you could be handling something that is over 200 C. Silicone would suck as a wire jacket, it is very "tacky" and "delicate". It'd get torn to bits being pulled through conduit on the job.Mr_Fix_it wrote:Hi, I don't want to rain on anyone's parade, But,,, Correct me if I'm wrong... I was under the impression that there is a fairly high concentration of silicone in multi filament wire insulation.

A little blurb from wikipedia:
Electrical wires may be insulated with polyethylene, crosslinked polyethylene (either through electron beam processing or chemical crosslinking), PVC, Kapton, rubber-like polymers, oil impregnated paper, Teflon, silicone, or modified ethylene tetrafluoroethylene (ETFE)
Tonight had me sealing up the right hand. Using my gut feeling after working on the left hand, I blended in two strips of TPE filler about the size pictured sitting on her palm into the bottom of the incision. I then only needed a very thin 3rd strip to level off the top of the bond.
How it looked after the first pass through with the soldering iron, but that's not good enough.
Alright, got that blended out about as well as the iron will do
\
I then utilized the hot spoon method to smooth out the work area, and then retextured with sand paper (220 grit) after heating the area with the hot air gun on my workstation set to 135. Powder application reveals a little kind of "skin tag" in the middle of the palm. I can deal with that later.
Did the same to the left hand, powder reveals what appears as a "scratch" at the edge of where the spoon smoothed out to, in line horizontally with the pinky. That could possibly come away with mineral oil on a Q-tip gently rubbed/rotated on it. Again, I can deal with that later. As an aside, I have a family member arriving tomorrow and staying for a week, so after all this... I have to clean everything up and put Sephonia away
As I was powdering her hands, her eyes fluttered open as the anesthesia wore off.
Sephonia: Mau5, I feel funny... down there (pointing to her crotch)
Mau5: Well, I just fixed you up. Must be the anesthetic wearing off.
Sephonia: No, it's different.
Mau5: Well, it looked like you'd given birth 1000 times so I patched you up.
Sephonia: *giggles* Not what I'm talking about. I don't know what was in that anesthetic, but I am HORNY! You need to take care of me, RIGHT NOW!
Mau5: Hun, I've been taking care of you all week, surely you need some rest after what you'e just been thr...
*Mau5 gets cut off mid-sentence as Sephonia plants a sloppy wet kiss on his lips*
*grinning* Mau5: Well, I think I know just how to take care of you now
Sephonia thinks her nipple job was OK, and gives a *thumbs up* to her hand repair

Re: Sephonia goes under the knife (Finger replacement + vari
Loved the finger wire idea
I replaced all Mia's finger wires but the replacements quickly snapped again
Not sure if I missed it but what gauge wire did you use?
Re: Sephonia goes under the knife (Finger replacement + vari
OK, time to do a little self-review. As I just mentioned, the colour of wire insulation used should be given some consideration as it can show through the fingers/hands. I had the wire already as I used it on my motorcycle, and I'm thrifty by nature
I was going to cap the wires with some heat-shrink tubing. I thought I had some, but I couldn't find where I'd put it. In my haste to wrap up the project and put things away before my visitor arrived, I went without caps. I stretched the wire insulation a little so that the wire strands were slightly recessed at the tip. The open end made running the wires down the fingers a little more difficult than it should have been, and increased the risk of poke-through. I would definitely cap the wires next time. I like Arthur's wire cap idea, but rather than fit the cap over the wire insulation, I'd size it to the copper and strip off a little insulation at the wire tip so the cap covers the copper and is as flush as possible to the insulation.
For incision sealing, a few filler strips of TPE added to the bottom of the cut is necessary as the incision will crater if using the heat method of bonding. I'm quite pleased with the final finish after smoothing.
The stranded copper wire can be posed, but expect to over-bend and have it spring back to the desired position. Finger TPE can get a little twisted since it is no longer bonded to the wire, but that is easily straightened out. Just exercise due care when handling the fingers.
The TPE work was the most daunting aspect of the job for me, as it was a new skill to learn. I recommend acquiring a sample piece from your vendor to learn on before working on your doll. It's not too difficult, but you do need to get some "experience" with how the TPE reacts to the tools/heat. Once you feel comfortable working on the sample piece, try it on a less visible area of your doll that needs repairs. I have standing feet that had some tears around the foot pegs, so I practiced there first.
The first cut is the most difficult, there is no turning back once you do it, you are committed. I understand the anxiety that comes along with doing something like this for the first time, wondering if your doll will ever be OK again. Try to relax and take things a step at a time. Walk away for a bit if a certain task is causing frustration. It's better to come back fresh and relaxed than to make a mistake out of haste. I don't know if others have felt the same, but after I finished the final smoothing an incredible feeling of relief washed over me and I was smiling, she was back It is so worth everything involved to do this for your girl.
