Burnt fingers

Hello there! 

A lot has been going on recently and everything has been very hectic. Last week I made my first ball and socket armature so I thought I'd show a few behind the scenes photos and not really a tutorial but a bit of a ramble about it :)

So when I say "I made my first ball and socket armature" I kind of didn't make it all myself in that I used various pre made joints and soldered everything together. I dont have the equipment to make my own joints and why worry when there are some fantastic joints out there already for the taking, albeit a pricey taking in some respects.

The knee and elbow joints are from the amazing John Wright http://www.jwmm.co.uk/
John Wright's supplies Aardman with a lot of their joints and also a lot of other people in the UK and Europe. They are pricey but most definitely worth it as the quality is outstanding! He also gives you a length of steel rod for each joint making it even easier to put the parts of your armature together.

All the other joints and everything else for this armature is from a shop that just gets better and better all of the time and is definitely helping to make stop motion more accessible to everybody. The joints can be bought separately or as part of the fantastic armature kit 'Armacreature'
It's hard not to sound like a sales pitch but this is the best armature kit I have ever used and I have used a lot of them! http://www.animationtoolkit.co.uk/armacreature-professional-armature-kit/


With all of the rods, K & S and steel plates cut to size, it was time to get messy.


Most of the components

My dirty colourful soldering block

All of the parts soldered together They almost look like I've gone into the piercing business

Getting there!



Now, for the leg and arm sections I needed to solder a nut on to the ends so that I can slot hands & feet in and lock them of to stop them slipping out while the puppet is being move around or even while it holds its position. I drilled a whole through the K&S to the correct size then to keep the nut in place while soldering I just used some old screws to keep it weighed down and to also stop any rogue bits of silver solder getting into the thread of the nut.  A tiny 3mm grub screw is what pops inside when done and tightens up with a wee allen key.


As I'm fairly new to silver soldering I did find that I ended up charring most of the components but
 that's ok as a little bit of elbow grease some jewelers pickle and some sanding got all of the marks off. I also managed to mutilate myself with various burns and cuts and a good old poke in the eye but hey its not a proper job unless you injure yourself, right?

All the soldering done but very charred!

After all of the soldering was finished I needed to then grind down the joints as even though they are small they were not small enough. This was a tough job as I need to make sure they stay strong enough for the job. But with a bit of TLC and mini bench grinder, all went well.

And here he is all finished. He stands at just over 11" tall








Here is a video that i made for my client. It also shows the balsa sections I add so it makes the puppet easier to grab at when moving around.



I actually really, really enjoyed making this and can happily say it has been my favourite part so far of this puppet build. I cant wait to make another one!


I'm currently working on casting his body in silicone. Hopefully I'll have a spare few moments to document how that goes.
Anyway, back to work! I hope you are all doing great!

Time Flys

I really cant believe it has been over a month since my last post! Time really does fly way too quick.

So in my last post I mentioned that I would be starting a new armature and also playing with plasticine. On with the show!

Now Plasticine is lovely stuff! I'm still getting used to it as I normally sculpt with harder materials so having something that squishes easily can be a bit frustrating at first but when you get used to how much pressure you need to apply it  soon becomes a nice and quick way of doing sculptures/ puppet heads.

I had seen that Aardman use an under skull to bulk out the plasticine and too also make it easier when digging the current mouth out to add a new one. I made a few out of some K&S and polymorph. One thing I did find it that you must have some room for the eyes so when the plasticine is layer on the skull you can make large enough holes for the eyes to sit firmly and not be sticking out the head too much.
I had to go through a few to find this out




And here is my first quick sculpt with plasticine 


Then my second with a version on the end of how I would like it to finally look 


I did do a quick sculpt that I could try out some replacement mouths with. He ended up looking a bit too much like Wallace and i probably wont use him for anything . I have still yet to find the time to test it out but hopefully will be able to by the end of next week.


Then this is pretty much the last sculpt I did. I'm finding it quite hard to smooth the plasticine out in small corners e.g the corners of the nose and under the eyebrows. I still need to play with a bit more to figure that one out.




I have also finished building a new armature. After my last big bugger of a puppet I decided to keep the size of it to about 8-9" and it really is considerably smaller then the last puppet. I have gone to great lengths to make sure it is sturdy as I can get it. I think I am going to do some animation tests before I pad it out and finish it off. Just to make sure everything is fine. One big mistake I did make was completely forgetting about a rig point. I'm not too worried about that at the moment but if i do need to rig it I will just have to do the old wrap wire around the puppet and hope for the best!. Also this time I have tapped some threaded holes in to the feet for tie downs and also used the same steel as before so that if I want to try out magnets again I can. The only thing I need to do is add some K & S to the neck so I can slot in a head
As this puppet is going to have plasticine hands I don't need to have wire fingers as I have heard it is easier to re sculpt the hands then have wire popping though all the time. A washer is used as the base for the hand. I still need to wrap it up in some cloth tape so the plasticine wont come of the armature.
And here is the finished armature!
The next step is to do some quick tests with it before I move on. I should hopefully do this over the next few days.

Puppet Progress

I cant believe it has been just over 2 weeks since my last post. Doesn't time bloomin fly ey!

My training puppet is coming along very nicely.  After doing the hand test with the liquid latex I decided I would do both hands at the same time while the technique is still fresh in my head.

I took a few step by step pictures of how I do my hand armatures as I think they are very simple to do but but very strong.



With one strand of 1mm aluminium wire I make the basic shape of a hand




Then I hold the bottom of each finger and twist the wire leaving a loop at the top to form the base of the fingertip. I also twist the wire to form the wrist and forearm


Then with what ever wire that is left from the forearm I double back up to the wrist and wrap it around to form the base of the palm of the hand. Thats it, you now have a quick and easy hand armature!



Also here is a couple of photos of adding the thin foam to the hands and then cut into shape ready for the latex build up




The hands did not come out as good as my last try but they will do as I'm not going for perfection with this puppet. You will see them in a few photos a bit further down.


The next step was to make the main body armature. I had already roughed up the proportions and armature design but left them very sketchy as I knew I wanted to make adjustments as I went along.


I started out with two blocks of wood for the hips and chest. I sawed these down to the right sizes and then rounded off the edges.
I drilled holes in the top of the chest block so I could slot the wire into to it for the arms and neck and did the same for the hip block. For the arms and spine/neck wire glued some aluminium tubing to harden up the areas that dont need to be manipulated. I attached the hands and also made a neck by using the same build up technique that I used to make the hands. I have also drilled a hole in the hip block to attach a rig when needed.


The next step was to sort him some feet out. This took a few days of trial and error as I want the puppet to have toe joints. The feet are made from steel strips as I am going to try out magnets instead of tie downs. At first I tried to make aluminium braces to clamp the wire down to the steel. The only way to do this was using 5minute epoxy. I glued them together then clamped them with spring clips to keep them secure.



Unfortunately this didn't work as the epoxy does not seem to bond steel and aluminium very well. The next step was to try soldering them but I had to wait a few days for that as I was waiting on an order of silver solder, flux and some square K&S tubing.
When they finally arrived I decided to ditch the brace idea and use K&S tube to fix the wire to the steel feet plates. The first test I did was with one piece of tubing but when it was done I attached it to the puppet and I found the ankles were not strong at all and would just bend too easily. So I doubled up the K&S tubing and wire that went into to them create a stronger joint. this worked great and was very happy with the results.



The finished feet armatures



While I was waiting for the materials to arrive I started to pad the top half of him out.


The next thing I did was to make shoes for him. I made them using the liquid latex build up as I need the toes to bend. Using some cushion foam I made the base of the shoes which I think look like slippers!  After the glue had dried I chopped them down to right shape.


I then added in some very basic details like the back of the shoe, tongues and a rim around the outside.


Then it was time to add the latex. I didn't smooth the whole shoe as I was liking the texture it was producing when drying.
One tip I can offer is if your doing latex build up work and adding it on to foam it takes a while to dry so I found out using a hairdryer to heat it speeds the curing process up quite a lot. Remember though if you have a very thick bits/pools of latex it will just dry the top layer and underneath will not be 100% cured.

The finished feet



After the feet were complete I could pad the rest of the puppet. I only took one photo of that step as I worked pretty fast and didn't really stop while doing it.

I wanted to leave the puppet like this!!




So that's pretty much where I have gotten to with this chappy. He is at this moment in time lying on the table ready to be clothed. I have all the patterns done and some material cut ready to be sewn. I also need to paint up some wood for an animation table and also make the rig to support him when running/jumping but I have to get some photography work out of the way first before I can do those jobs. Hopefully this time next week I will have some animation tests done to show you.

So I will leave you with a sneaky look at how he is looking at the moment even though he is pretty much naked! Hope you are all doing well

Heads & Hands

I have been trying to decide what kind of training puppet I am going to make. So At the moment I am kind of just playing around. The first thing I did was make a solid head as I thought it would help with concentrating on body physics and not have to worry about the facial movements. So I sculpted up something that has a bit of a children's TV character look to it. Nothing moves on this apart from the blinks that I have not made yet.

He is sculpted out of Super Sculpy Firm then airbrushed and touched up with a paintbrush.

A quick concept sketch that the head sculpt is based on

The baked head

A quick digital paint over to get the right colours

Then the final head all finished



Yesterday I spent the whole day playing around with the liquid latex build up technique. I had always wanted to try this out but was swayed by the look and feel of silicone. So I thought why not have a go?
It turned out to be a lot nicer and more relaxing than I had thought it would be.

I have been studying Nick Hilligoss's Build up tutorial videos which if you haven't seen then here is the links. Very inspiring stuff ------- HEADS & BODY

I have started out with making hands as I'm going to need some for my new puppet.

I followed how Nick does armatures for hands but ended up forming my own way of doing it.
Then Got some really thin bandage foam and gave it a coat of some adhesive spray and I wrapped it around the armature. I didn't take any photos of this part of the process as its was a very sticky and messy job and didn't want to get my camera grubby.

Next came the liquid latex. I was lucky that I have flesh tinted latex but if you want to paint it or add your own tint you need to get some ammonia to stop the latex reacting with the paint and going all lumpy.
My first attempt was quite poor but at least it let me get the feel for how the technique works. Learning how fast the latex drys and if there is any really deep pools it will take a lot longer to fully cure.

My first attempt

It reminds me of an old B-movies aliens hand :D But it did pave the way for my last attempt.
I am actually really pleased with how this turned out and actually prefer them to any of the silicone hands I have made. A couple of things I'm not happy about is the thickness and length of the fingers and I also went a bit overboard with trying to put detail on the back of the hand. No matter though as its just a test.
