1
00:00:09,320 --> 00:00:10,520
Okay, so I'll be 

2
00:00:10,520 --> 00:00:13,520
doing a series of three videos,
 this is one of three,

3
00:00:13,520 --> 00:00:16,480
and we're going to be showing you
 how to make a hand.

4
00:00:16,880 --> 00:00:21,280
So in this video, I'm going to be showing
 you how to take a life cast of a hand.

5
00:00:21,280 --> 00:00:24,840
I've got my model, Chris, here,
 in the second video,

6
00:00:24,840 --> 00:00:29,560
I'm going to be showing you how to run
 the different products into the mould.

7
00:00:29,560 --> 00:00:32,760
And then in the third video, I'm
 going to show you some different finishing

8
00:00:32,760 --> 00:00:36,000
techniques as well
 how to create something that's realistic,

9
00:00:36,000 --> 00:00:40,160
but also something that's a little bit
 more kind of character based as well.

10
00:00:40,360 --> 00:00:41,520
So let's start off with I'm 

11
00:00:41,520 --> 00:00:44,640
just going to get Chris
 to put some petroleum jelly onto his hand

12
00:00:45,880 --> 00:00:48,200
just to make the release nice and easy.

13
00:00:53,800 --> 00:00:57,000
So while Chris is doing that, I'm
 going to mix up the silicon that we use

14
00:00:57,000 --> 00:01:00,880
and so we using Go-cast
 which is a life casting silicon.

15
00:01:01,160 --> 00:01:06,440
I've got part A and part B and you need to
 mix of equal parts of those products.

16
00:01:06,680 --> 00:01:10,200
I've got my scales here to weigh out
 and I'm also going to label up

17
00:01:10,240 --> 00:01:14,000
my spatula as Part A and B,
 so I don't get them mixed up.

18
00:01:14,560 --> 00:01:17,680
I don't want to be contaminating
 either of these parts

19
00:01:17,680 --> 00:01:20,680
because then it will cure within the tubs.

20
00:01:20,680 --> 00:01:25,200
The great thing with the Go-Cast
 is that your A and B are different colors,

21
00:01:25,200 --> 00:01:38,440
so to start off with I'm
 going to mix up my A,

22
00:01:38,440 --> 00:01:46,680
so I'm just going to change my
 gloves because I've got part

23
00:01:48,160 --> 00:01:50,960
A on and I don't want to be having any A

24
00:01:50,960 --> 00:01:53,520
on my gloves when I'm going into Part B.

25
00:01:56,920 --> 00:02:00,680
So I've just measured out my part A
 and now I'm just going to measure out

26
00:02:00,680 --> 00:02:03,560
my Part B, so I want equal parts.

27
00:02:21,040 --> 00:02:23,520
So now I've got equal parts of my A

28
00:02:23,520 --> 00:02:27,440
and B silicon in my tub
 I'm just going to mix those up.

29
00:02:27,440 --> 00:02:32,200
So you've got part A which is more
 of a pink colour and Part B, the blue.

30
00:02:32,480 --> 00:02:35,080
And as you mixing it up, you'll be able.

31
00:02:35,080 --> 00:02:39,440
It's nice and easy because you can once
 your colours are mixed in the products

32
00:02:39,600 --> 00:02:42,440
mixed properly together. 

33
00:02:45,560 --> 00:02:48,600
So once the both parts are mixed together,

34
00:02:49,600 --> 00:02:51,480
that's what we have. 

35
00:02:51,600 --> 00:02:53,720
So now I'm just going to apply this 

36
00:02:53,720 --> 00:02:56,560
onto Chris's skin, and I want to do nice

37
00:02:57,240 --> 00:03:01,000
even coat
 to make sure we capture all the detail.

38
00:03:06,840 --> 00:03:09,080
I've put some couchroll down

39
00:03:09,080 --> 00:03:12,920
just because it is going to drip and
 I don't want to make too much of a mess

40
00:03:12,920 --> 00:03:17,120
and have a big clean up afterwards
 so if you've got some either

41
00:03:17,120 --> 00:03:20,440
plastic or cling film or couch roll

42
00:03:20,440 --> 00:03:24,320
you can just pop that down. 

43
00:03:25,200 --> 00:03:26,160
And it makes it easier 

44
00:03:26,160 --> 00:03:31,800
to clear up.

45
00:03:31,800 --> 00:03:40,200
The first coat you want to be focusing on
 just making sure that you haven't

46
00:03:40,240 --> 00:03:43,640
got any air bubbles in
 because you want to make sure you capture

47
00:03:43,960 --> 00:03:46,360
all the detail on the hand. 

48
00:03:46,360 --> 00:03:49,200
And that's the biggest focus
 of your first coat.

49
00:03:51,520 --> 00:03:57,640
With silicone,
 this silicon is temperature dependent,

50
00:03:57,640 --> 00:04:01,920
so if you've got a warmer room
 or a warmer model to work on

51
00:04:01,920 --> 00:04:06,160
from their body temperature,
 then it's going to cure quicker.

52
00:04:06,520 --> 00:04:10,680
Whereas if you're in a cold room
 or a colder environment or the models

53
00:04:10,840 --> 00:04:14,560
got cold hands
 then it's going to take longer to cure.

54
00:04:14,560 --> 00:04:18,520
You can, if they have got really cold
 hands, you can maybe get them to run them

55
00:04:18,880 --> 00:04:21,320
under some hot water to start off with.

56
00:04:21,720 --> 00:04:26,360
Same as if your models really warm
 they can run it under cold water.

57
00:04:26,360 --> 00:04:30,680
Once you've applied the silicon,
 use a hair dryer

58
00:04:30,680 --> 00:04:33,280
just to speed up
 that curing process as well.

59
00:04:33,680 --> 00:04:37,920
Just always make sure that your models
 are comfortable and you keep checking

60
00:04:37,920 --> 00:04:39,200
that the heat isn't buring them.

61
00:04:54,040 --> 00:04:54,560
OK, so 

62
00:04:54,560 --> 00:04:57,760
now we're fully covered with no air
 bubbles, we've covered

63
00:04:57,760 --> 00:05:00,800
all the area, of the hand
 we just need it for the silicon

64
00:05:00,800 --> 00:05:03,880
to cure it now
 roughly about ten to 15 minutes, again

65
00:05:03,920 --> 00:05:07,440
depending on body temperature
 and room temperature,

66
00:05:07,680 --> 00:05:10,560
and just for the product to cure
 before we add our next layer.

67
00:05:17,880 --> 00:05:20,600
So we're cured now

68
00:05:20,600 --> 00:05:24,160
so I'm going to mix up
 another batch of equal parts of the A

69
00:05:24,160 --> 00:05:27,040
and the B go-cast,
 and we're going to add another layer.

70
00:05:29,520 --> 00:05:30,040
So again, 

71
00:05:30,040 --> 00:05:33,160
I've labeled up my spatulas with A and B.

72
00:05:33,400 --> 00:05:37,080
I've got my scales out,
 and my pot to mix in.

73
00:05:43,160 --> 00:05:45,600
So I'm roughly using 100 grams of A

74
00:05:45,600 --> 00:05:50,040
and 100 grams of B as well,
 so we've got a 200 gram mix

75
00:05:51,360 --> 00:05:52,280
and so always make 

76
00:05:52,280 --> 00:05:54,880
sure you just clean off
 any excess from your tubs

77
00:05:55,320 --> 00:05:57,640
as well before you put the lids on.

78
00:05:59,560 --> 00:06:01,920
So I'm just making sure
 I've cleaned my hands as well

79
00:06:01,920 --> 00:06:04,800
before I decant the B. 

80
00:06:18,440 --> 00:06:20,600
And then just going to repeat as before,

81
00:06:20,600 --> 00:06:24,720
and I'm just going to mix up the A
 and the B back together again.

82
00:06:27,640 --> 00:06:28,720
And make sure you get round 

83
00:06:28,720 --> 00:06:32,840
all the sides and into the bottom as well,
 so its mixed thoroughly.

84
00:06:32,840 --> 00:06:36,560
So on this layer what we're going to try
 and do at the moment

85
00:06:36,560 --> 00:06:39,760
with almost got a glove going on
 so all our fingers are separate,

86
00:06:40,000 --> 00:06:42,320
we're going to be looking
 at creating more of a mitten now.

87
00:06:42,320 --> 00:06:44,080
So we're going to have the thumb 

88
00:06:44,080 --> 00:06:48,080
separate to where the four fingers are
 and we're going to mould them together.

89
00:07:00,720 --> 00:07:02,640
So once I've applied 

90
00:07:02,640 --> 00:07:06,640
this layer, we usually apply

91
00:07:06,640 --> 00:07:09,920
two to three layers, depending
 on the thickness that you've got.

92
00:07:09,920 --> 00:07:11,840
I think we might actually be okay 

93
00:07:11,840 --> 00:07:15,640
with just these two layers
 today, it's covering quite nicely.

94
00:07:16,000 --> 00:07:20,560
And the silicone,
 when just on its own, is quite flexible.

95
00:07:20,920 --> 00:07:25,120
So it means when we fill
 the mould with a product, it might distort

96
00:07:25,120 --> 00:07:29,040
and we might get some funny
 shapes on the hand and fingers.

97
00:07:29,280 --> 00:07:32,800
So what we're going to add to this,
 is we're going to create a modroc

98
00:07:32,800 --> 00:07:35,400
shell around it
 just using plaster bandages.

99
00:07:36,000 --> 00:07:40,320
And what that will do
 is that will reinforce the mould,

100
00:07:40,320 --> 00:07:44,000
and it'll mean it's nice and sturdy
 when we come to fill in

101
00:07:45,240 --> 00:07:47,840
the mould with the products
 that we're going to run it in.

102
00:07:48,960 --> 00:07:49,720
And so we've got 

103
00:07:49,720 --> 00:07:52,440
a second coat on there,
 we've gone from having

104
00:07:53,200 --> 00:07:55,760
almost like a glove to now
 wearing a mitten,

105
00:07:55,760 --> 00:07:59,680
which will make it a lot easier
 for adding that modroc shell.

106
00:07:59,840 --> 00:08:02,920
We're not going to have to go around
 all the fingers individually.

107
00:08:02,920 --> 00:08:05,400
So I'm just going to smooth.

108
00:08:11,200 --> 00:08:13,440
around the mould. 

109
00:08:25,480 --> 00:08:26,760
OK, now we're going to wait for that 

110
00:08:26,760 --> 00:08:28,840
to cure
 before we move on to the next step.

111
00:08:31,920 --> 00:08:35,680
So I'm going to be using some modroc
 which is a plaster bandage.

112
00:08:35,960 --> 00:08:39,320
It's quite dusty,
 so I'm going to be wearing a dustmask

113
00:08:39,320 --> 00:08:41,520
just to protect myself.

114
00:08:42,680 --> 00:08:44,560
So I've got my truck. 

115
00:08:44,560 --> 00:08:49,360
I'm just going to fold in half
 and then dip it into the water,

116
00:08:49,640 --> 00:08:51,240
and it wants to be nice and creamy, 

117
00:08:51,240 --> 00:08:55,520
so I'm just going to massage the water
 into the plaster to activate it.

118
00:08:57,840 --> 00:08:58,600
As you 

119
00:08:58,600 --> 00:09:03,440
see, you get that nice creaminess

120
00:09:05,240 --> 00:09:09,040
and then I'm just going to apply it. 

121
00:09:09,680 --> 00:09:12,800
So I'm going to do half of the hunt
 to start off with.

122
00:09:13,440 --> 00:09:16,920
And then what we do
 is I'm going to build a ridge around here

123
00:09:17,760 --> 00:09:20,880
and then I'm going to apply some petroleum
 jelly as a release agent

124
00:09:20,880 --> 00:09:23,120
and then I'm going to do the other side.

125
00:09:38,560 --> 00:09:44,520
So I'm doing about four layers
 with the modroc,

126
00:09:44,880 --> 00:09:49,120
I'm folding each layer over as I do it
 so I'm putting two down at a time.

127
00:09:54,960 --> 00:09:57,320
And then I'm just going to make

128
00:09:58,560 --> 00:10:01,640
my ridge now,
 so I'm going to take some larger

129
00:10:01,640 --> 00:10:05,880
pieces of modroc
 and I'm going to fold these into four

130
00:10:07,320 --> 00:10:09,400
and I'm going to make a ridge 

131
00:10:09,400 --> 00:10:13,360
around the edge of my plaster modroc

132
00:10:13,360 --> 00:10:18,160
just to help the two parts
 of the mould hold together.

133
00:10:28,200 --> 00:10:28,600
So I just 

134
00:10:28,600 --> 00:10:30,880
want to make sure all thats massaged in.

135
00:10:38,680 --> 00:10:42,120
It's all nice and smooth. 

136
00:10:43,000 --> 00:10:44,400
You know, we need to do is just wait 

137
00:10:44,400 --> 00:10:49,760
for the modroc shell to dry and set,
 and it'll be a nice it'll be nice

138
00:10:49,760 --> 00:10:52,560
and hard, it will warm up a little bit
 as it's setting

139
00:10:54,080 --> 00:10:57,360
So just let your model know that,
 it wont get hot,

140
00:10:57,720 --> 00:11:01,800
it'll just be a little bit of a heat
 as that plaster sets.

141
00:11:01,800 --> 00:11:05,640
So he's going to wait for that side to dry
 before we move on to the other side.

142
00:11:07,480 --> 00:11:09,120
OK, so 

143
00:11:09,840 --> 00:11:12,840
our modroc shells
 nice and hard now, what we're going to do

144
00:11:12,840 --> 00:11:16,160
is going to turn hand over
 and I'm just going to apply

145
00:11:16,480 --> 00:11:20,000
a layer of petroleum
 jelly to the ledge that I created

146
00:11:20,400 --> 00:11:24,840
just to stop the next half of
 the mould sticking to itself.

147
00:11:28,560 --> 00:11:29,960
So the petroleum jelly is 

148
00:11:29,960 --> 00:11:33,360
going to act as a mould release. 

149
00:11:40,520 --> 00:11:43,760
So got that second
 part of the mould on now.

150
00:11:44,000 --> 00:11:48,560
We just need to wait for that set
 and then we'll remove it.

151
00:11:48,560 --> 00:11:52,600
So the mold all hard now

152
00:11:52,880 --> 00:11:56,120
and what Chris is going to do is just have
 a little wiggle of his fingers

153
00:11:56,120 --> 00:11:57,480
inside. 

154
00:12:00,920 --> 00:12:02,560
There we go. 

155
00:12:02,560 --> 00:12:04,880
And that's our mould. 

156
00:12:04,880 --> 00:12:08,280
So what we can do is
 we can take these modroc parts,

157
00:12:09,040 --> 00:12:12,120
separate these modroc parts
 because it's got petroleum

158
00:12:12,120 --> 00:12:14,520
jelly on they'll come apart nice and easy.

159
00:12:15,240 --> 00:12:18,920
And then we have
 our silicone mould inside.

160
00:12:19,520 --> 00:12:23,000
And what we're going to do
 in the next video, video number two

161
00:12:23,240 --> 00:12:25,840
is we're actually going
 to be filling this mold

162
00:12:27,440 --> 00:12:31,440
and we're going to be making a hand.

163
00:12:32,640 --> 00:12:35,000
Just a reminder to always make sure
 that you clean

164
00:12:35,000 --> 00:12:39,240
your area down,
 you wipe down all your products after use.

165
00:12:39,240 --> 00:12:44,000
And just bear in mind,
 I've got now a bowl of water

166
00:12:44,000 --> 00:12:46,600
with some plaster
 in, do not tip this down the sink.

167
00:12:46,920 --> 00:12:49,560
What you need to do is you need to wait
 for the plaster to settle.

168
00:12:49,800 --> 00:12:52,400
You can scoop up the top of the water
 and dispose of it,

169
00:12:52,400 --> 00:12:54,520
and then you just need to take some tissue 

170
00:12:54,520 --> 00:12:57,480
and wipe out the plaster
 that's in there and put it in the bin.
