What follows is a collection of links to various tutorials and information pages on repair, maintenance, and some modifications on mostly Obitsu 50cm bodies. Much of this information is also applicable to Azone 50cm, Angel Philias, Parabox 40cm to 50cm, Real Art Projects, Visuadolls, and Yamato VMF50s.

With the exception of the Mimiwoo tutorial all of these references were authored by the dedicated vinylolgists here at the MV Lab.

Currently there are a few titles without links. These are tutorials I know I have posted somewhere but I just haven't re-found them yet. Some of these posts were on other forums that have gone the way of the dodo. Posts that have been permanently lost to the ether will eventually be reconstructed and posted in this thread.

This article addresses one of the eccentricities of the Obitsu 50cm body: the motion of the wrist joint. The Obitsu 50cm hand/wrist joint is very flexible and replicates all the common wrist motions, but the "default" motion direction is a little weird. This is a choice that was made at the factory for who knows what reason.

I will be referencing the motion direction indicated in the image below.

 

Hand01a.jpg

 

The Obitsu 50cm wrist joint part consists off a long peg that inserts into the forearm, a wrist ball, which houses a hinge joint, and a double tab that inserts into the hand and holds the hand in place.

On the normal humans the most common wrist/hand movement is moving the hand up and down, the pitch motion in my image. On the 50cm for some reason the tabs on the wrist joint are oriented to hold the hand so that the wrist hinge joint is in the yaw movement. While wrists do move this way it is not the most common or comfortable wrist movement. Try it with your own wrist.

You can rotate the hand vinyl 90 degrees so it is oriented so the hinge moves the hand in the more natural pitch direction. The oval shape of the tabs and the opening of the hand vinyl makes this not the most comfortable of fits, but it will work on the default hands. I have most of my 50cm hands oriented like this. Many of the option hands have smaller openings and flatter inner spaces making orienting the hands to the pitch position difficult. If you are really dedicated like me (a.k.a. crazy) you can sand/file the tabs so that the option hands fit on the joint part in this natural position better. I have wrist joint parts with all my option hands mounted on them and have been modding the tabs to accommodate the various option hands as I use them. Modding the wrist joint in such a way can mean that some hands will not fit firmly. In such cases a little eye putty filling the interior of the hand will remedy this.

This was my only non-eye pocket head, the Gretel head of my ridiculously busty girl, Nyoko-chan.

The obligatory "Before" shot. Note the shadowing from the lids on the eyes.

 

001.jpg

 

These are the eyes after I removed them. They were advertised as 18mm (actually more like 19mm) with high domes.

 

002.jpg   

 

This is what the inside of the head looked like. Nothing has been done at this point. The stuff around the eye holes is residual eye puddy. You can see there was a little "factory" beveling.

 

003.jpg       

 

Here's the beveler from Luts

 

004.jpg

 

I used the beveler in my variable speed Dremel at a low setting, about 2 on the Dremel's 0 to 6 scale. I chose the lower settings for better control and so as not to heat (melt) the vinyl. Go slow, this was probably less than 10 seconds of grinding!

 

 

Here's the first "after" shot. The eye hole on the right has been beveled.

 

005.jpg

 

Here's an after shot, the eye on the left beveled, the other not beveled. The slight bevel brought the dome farther out of the eye hole and as you can see, it's brighter and reflecting a lot more light. I did try to light both halves of the head evenly for this shot. I'm just holding the eyes in with my fingers so getting them even was not easy. Unfortunately, the area beveled was also where her eyelashes were glued on so they were almost totally ground off (oops!).

 

006.jpg

 

And here is the "After" shot, eyes in place and puddy installed. She looks a little "bug eyed" without her eyelashes.

 

007.jpg

 

Overall, I thought the beveler worked well, bringing the eye "out from the shadows". The pupils are now much more visible than they were before. I would also guess that the actual eye shape (oval, round, etc.) would have a bit to do with the relative success of the operation. Some of the "flatter" shaped eyes might not fit into the beveled area as much. Also, I would do this (if I ever do it again) before the face-up. There was quite a bit of handling involved in doing this and obviously if you slip up you could easily grind off too much and remove some eyelid. I would hate to have that happen after doing the face-up.

One of the reasons the hip/leg joint can be hard to make completely is that the vinyl of the abdomen gets pushed into this joint and prevents the two parts from mating completely.

Here's a look at the two parts at the leg/hip joint without the vinyl. You can see there is a circular groove around the peg of the waist part. The tube of the hip part needs to fit cleanly and completely into this groove in order for the joint to be made firm.

HipJoint03.jpg

 

Frequently the abdomen vinyl is trimmed very tightly around the opening.

HipJoint02.jpg

 

With the vinyl so close it is common to pull the edge of the vinyl in between the two parts as you push the two parts together. When this happens, the two parts do not mate completely and if a big enough piece of vinyl is pulled in, the additional pressure can crack the outside ring of the waist part and/or the tube wall of the hip joint. The joint may seem firm at first but after a move or two the vinyl crushes and/or the hip joint part cracks and the unlocked leg becomes "swingy".

 

A preventative measure for this is to take a sharp xacto knife and trim the vinyl of the abdomen around this hole. The hole can be easily enlarged and is hidden by the leg parts so you don't have to worry about making the cut cosmetically perfect. This trimming can also be done to the torso vinyl at the shoulder, which also suffers from excess vinyl being pulled into the receiving tube.

 

With the shoulder joint, it is very easy to miss the receiving tube of the chest part.

ShoulderJoint02.jpg

 

With all the adjustability of the 50cm shoulder part it is easy for the receiving tubes to become misaligned with the hole in the chest vinyl. It would be a worth removing the chest vinyl, "zeroing out" the articulations of the chest part and inspecting it for damage. It is not uncommon for the receiving tubes on the chest part to crack. These cracks can be very fine and hard to see. Inserting the shoulder part onto the tube can help make any cracks appear. These cracks can be repaired by applying super glue to the crack and clamping with small zip ties. If the cracks are too large or the tube is falling apart replacement will be necessary.

This is one of those older tutorials that was on another forum, which has gone to internet heaven. Consequently I don't have a copy of the original text so I tried to recreate the text from the pictures alone. Kinda.

 

Removing the new neck piece from the head is not recommended. If at all possible leave the neck piece attached to the head. If you only need to remove the head from the body you can follow this procedure and stop once the head is off. If you must remove the neck piece from the head continue on but see the tutorial The New Obitsu Neck Piece for details on proper installation of the neck piece back into the head.

As with all such handling clean hands are a must.

To remove the head and neck piece, grasp the head over the top, squeezing the head at or below the ears. You want to create enough pressure so the head and the neck piece stay properly connected to one another. Keep squeezing the head and twist side to side while pulling up.

001.jpg

 

You should now have the head and neck piece assembly removed from the body.

002.jpg

 

To continue with the neck piece removal you will need to open the head by removing the head cap. Squeeze the head on the sides again. You might need to reposition your fingers up a little higher on the head, on the ears or above. This should open the seam between the head and the head cap. Once that gap opens up you should be able to pry off the head cap from the back. Always work from the back away from the face-up.

003.jpg

 

With the head cap off the inside of the head is exposed revealing the top of the neck piece and the eye pockets. In this image the neck piece is properly seated with the edges of the hole in the base of the head running through the grooves in the bottom of the neck piece locking collar.

004.jpg

 

To continue removing the neck piece, heat the head around the neck piece to soften the vinyl a bit. Try and avoid heating the face area.

005.jpg

 

Once the base of the head is warm, you should be able to push the neck piece up into and out of the hole and remove from the head.

006.jpg

 

When it comes time to reattach the head/neck piece to the body you will want to make sure the neck post at the top of the torso part is centered in the vinyl of the neck.

50cm Wrist Joint Part and Hands

Overview

The wrist joint parts of the Obitsu 50cm are identical, left and right. The joint assembly consists of the ball joint made up of an inner disk and two outer hemispherical ball sections. The outer ball sections are connected to the shaft/peg, which inserts into the forearm. The inner disk part of the joint is connected to the “paddle”, which inserts into the vinyl hand part. The paddle section consists of two main parts, an oblong disk, which is positioned flat against the joint ball and a connected half oval part, which protrudes into the hand. The oblong shape of the first disk prevents the vinyl hand from rotating easily on the hand serves to hold the hand vinyl on the wrist joint. Hand rotation is accomplished by the shaft of the wrist joint turning in the forearm.

Wrist joint part side view. Apparent size difference is due to perspective.

Installation and Removal

To easily install or remove hands from the wrist joint heating the hand is recommended to prevent undue stress to the wrist joint. Once heated the vinyl softens allowing easier insertion of the paddle end of the wrist joint. If hands are to be swapped often, the quickest and safest way to change hands is to have a set of wrist joints for each pair of hands. Pulling the wrist joint out of the forearm is relatively simple and does not stress the parts.

Hands, like most vinyl parts are made by pouring hot liquid vinyl into a mold. This method can produce parts with varying wall thicknesses. Furthermore, trimming of the excess vinyl can vary slightly. Along with different hand shapes, this means the hole where the wrist part is to be inserted can vary in size and shape. A small hole can mean the wrist joint will be difficult to insert. If the hole is too big, the hand may be loose and can fall off. If the hole in the hand part is too small, take a sharp hobby knife like and x-acto #11 and trim a tiny bit of vinyl from the inside of the hole. Trim a little bit at a time till the wrist joint paddle goes in and is still held by the oblong disk on the paddle. Be careful not to trim too much as this will make the hole too large and the oblong disk section will not hold the hand on.
 

Option hands showing some of the different opening sizes.

003.jpg

 

If the hands slips off the wrist part too easily, first make sure the hand is completely seated on the wrist joint. The hand vinyl should be completely covering the oblong disk section. If the oblong disk is covered completely and the hand is still too loose, you can stuff a little bit of eye putty in the hand to wedge against the paddle section. A thick bodied, space filling adhesive like hot glue can also be used if the hand installation is to be more permanent.

Properly and improperly seated hands on wrist joint part.

Most of the AP heads will look small on the 60cm body. Some "big hair" could remedy that but as always it's a matter of personal taste.

The Parabox Gretel head was designed for the 60cm body, but looks fine on the 50cm body and the 65cm body.

A "bigger" head (like DD or Obitsu 50-xx series) looks more anime stile on a smaller body like AP/Obitsu48.

Normal AP heads looks proportioned to the body, but smaller than anime-proportioned ones, so upscaling the body fron 48 to 60 cm will make the head looks even smaller and I don't think it's something good to see.
