Extra Tiny BJD Project: Part 3

Just to clarify, this little reindeer is made from carving wax and not any type of clay.  It is currently my favorite sculpting material.

A few hours more of work and below is the progress I have made.

As cute as it would have been to be able to swivel her ears, I have decided not to make them a separate joint.  They are now part of her head, which may make a challenge for making the head mold and casting it in resin.

Some of her body parts were made into a mold to help make reproduction easier.  A plaster mold would have added difficulty figuring out seam lines.  A moulage mold would have been temporary, but I needed to be able to use these molds for a while.  A silicone rubber mold would have been costly.  So I decided to use my Amazing Mold Putty.  I am able to quickly make re-useable molds which I can cast carving wax from.

Above you can see 3 molds I made.  The one on the far left is for casting legs, the top right is for the stubby antlers, and the bottom right is for the ears.

Extra Tiny BJD Project: Part 2

Today I spent a few hours working on my little reindeer.  I also learned that female reindeers can have antlers, so I will start calling the little reindeer a her instead of a him.  Right now her height from tip of toes to top of horn is about 2.25" total.

And for what you can't see from outward appearences...

The chest torso has the holes set for the neck and front leg joints.  This is where the strings will go through.  I hope there is enough space where the string can go without interfering with the ball joint of the mid section.

I am hoping I can add an elbow joint to the front limbs.  There will be no paw joints.  Still more work to do, but she is coming along nicely.

Extra Tiny BJD Project: Part 1

I was thinking of making a little animal BJD for a while, but I finally decided to work on one today.  He is supposed to be a little reindeer.  (I wanted to say she, but with antlers that makes it a he.)

Now to show how tiny he actually is.

His head is 0.75" long.  That should put things into perspective of what a tiny scale I am working on.  His head is so small I don't think I can do a head/face plate.  That also means he won't have removable eyes.  I suppose I will have to paint them on.

Above you can see all the parts involved.  One tiny ear, a head, both half of the copy, plus the midsection joint.  All that is left to create are the horns, tail, and legs.  Of course more refining is needed.

How difficult will this to string?  Is it doable?  I suppose I will find out.  This is going to be an exciting little side project.

Casting Pressure Pot Links

I should have a pressure pot for casting by the end of this year.  (I asked for a pressure pot for my upcoming birthday.)  It will be coming from the local Harbor Freight and will be 2.5 gallon in size.  I even have someone who will do the modifications needed to make this paint pot into a casting pressure pot.  But I need information on what needs to be done and what parts will be needed.  So below are some links about making the modification.  (I am posting this information all in one place so I can find it easily when I need it.)

NOTE:  This page is going to be randomly updated as I find more information pertaining to converting a paint pot to a pressure pot, plus other useful information about pressure pots.  So please excuse any random babbling.

2.2n Sculpting (Arisu)

It has been a while since I last updated and I have not made much progress.  With the holidays and other things I have coming up, I may not be able to do a lot of work.  Thus progress may be slow until the beginning of next year.  But I am going to try to keep working on her even if it is a little at a time.

Originally I had sculpted Arisu's arm prior to creating joints, but I think I should have waited in adding muscle details until after the joints are done.  Especially on my first doll since I don't have a clue how to do the joints.

Above is a picture from the post "4.1e Carving Wax (Arisu)" back in August.  (Wow, I have been working on her for a while now.)  You can see how her arm is sculpted to show muscle contours.

Since then I have decided that the arm is too thin and being contoured will probably make adding joints a little difficult for me.  So I ended up dipping the arm in hot wax like a person would dip a candle to add thickness.

Above you can see how the arm looked after it was dipped and how it looks after I carved it down with less details.

This arm is then cut where the elbow joint is and hollowed out.  I used the 10mm half round carving wax balls I originally used to cast carving wax 10mm eyes.  Two are put together to create a peanut shape.

The elbow joint is a tad over 90 degrees in its angle, but not by much.  I need to do a little more thinking to decide how to get a bit more angle while still looking good to me.  I was orginally thinking of aiming for a 145 degree angle (Joint Study: Elbow), but I may settle for at least 120 degrees.

There is still more to be done before one arm is done.  Then to make the other arm look the same.

Torso Joint Study 1.1

Although I can make my BJD with a one piece torso, creating joints will increase her poseability.  There are a few things to decide when considering torso joints.  I have to decide how many joints I want and where to locate those joints.

There is a good drawing of a few ideas about how to do the torso joint on the Enchanted Forums.

At first I was thinking of only having one torso joint, but ended up deciding with two joints to help increase poseability while hopefully maintaining an aesthetically pleasing natural look.  Her body is meant to be child-like so I don't expect her to bend like a gymnast.

Above you can see my drawing of how I would like her torso joint to be.  The first joint will be at the bottom of her rib cage and the second joint will be at her pelvis.

There is just one main problem with making perfectly round ball joints for the torso.  When one looks at the top view of a person, you will see that a person is longer side to side than front to back.  So the torso would be more elliptical than a circle.  You can see my illustration of this on the bottom part of the drawing.  This is one reason why I decided to do 2 joints instead of one.  Each joint will have a lesser degree of twist so that it will reduce gaps and keep parts from sticking out oddly.

So far I have only created one torso joint which is looking pretty good so far.  I will be adding the second joint soon for the lower torso.

Something else that needs to be considered when designing the torso is how I plan to make the silicone mold for it.  Will it be easy to make a mold or or complicated because of how I made the joints?  That is on my mind as I design the torso joints.

And last but not least, I still have to consider where to put stops so that the body is not posed in ways it is not meant to be, thus causing odd angles and pop outs.
