1
00:00:08,160 --> 00:00:11,880
Right.  This is an introduction to

2
00:00:11,880 --> 00:00:15,480
using a barrel polisher  and the barrel polisher 

3
00:00:15,480 --> 00:00:20,400
is generally the final stage

4
00:00:20,400 --> 00:00:24,420
before you take that ring away or

5
00:00:24,420 --> 00:00:26,620
that bit of jewelry chain 

6
00:00:26,620 --> 00:00:29,320
and give it as a present.

7
00:00:29,320 --> 00:00:30,880
So you've soldered 

8
00:00:30,880 --> 00:00:33,660
and you've used the polishing machine

9
00:00:33,660 --> 00:00:36,900
and everything's cleaned up.

10
00:00:36,900 --> 00:00:38,800
And 

11
00:00:38,800 --> 00:00:43,600
the little barrel polisher is

12
00:00:43,600 --> 00:00:48,660
a tool that gently cleans the

13
00:00:48,660 --> 00:00:50,400
- polishes the surface 

14
00:00:50,400 --> 00:00:52,560
and it's not abrasive. 

15
00:00:52,560 --> 00:00:54,700
It burnishes the surface 

16
00:00:54,700 --> 00:00:57,780
just like the burnisher we used 

17
00:00:57,780 --> 00:00:59,560
for the edges of the bit of copper 

18
00:00:59,560 --> 00:01:02,640
in the previous videos. But.

19
00:01:02,640 --> 00:01:05,220
These barrels are 

20
00:01:05,220 --> 00:01:06,780
filled with thousands 

21
00:01:06,780 --> 00:01:09,360
of these little ball bearings

22
00:01:09,360 --> 00:01:11,940
and some little elongated ones

23
00:01:11,940 --> 00:01:15,560
and some sort of spaceships shaped ones.

24
00:01:15,560 --> 00:01:18,140
And they're all different shapes,

25
00:01:18,140 --> 00:01:20,720
so they fit into the

26
00:01:20,720 --> 00:01:22,800
into the contours of

27
00:01:22,800 --> 00:01:24,860
different pieces of metal.

28
00:01:29,300 --> 00:01:33,200
The shot, this is called shot and

29
00:01:33,200 --> 00:01:35,660
it all it goes into the barrel, 

30
00:01:35,660 --> 00:01:37,760
and it's quite straightforward. 

31
00:01:37,760 --> 00:01:39,440
The barrel has baffles in it, 

32
00:01:39,440 --> 00:01:43,640
so as it rolls over and over it, it

33
00:01:43,640 --> 00:01:48,000
churns up the shot as it goes round.

34
00:01:48,000 --> 00:01:51,240
Mix a bit of water, just a bit of water.

35
00:01:51,240 --> 00:01:56,520
So it's sort of just covering the shot

36
00:01:56,520 --> 00:02:00,600
and then just to help it all along.

37
00:02:00,600 --> 00:02:03,680
There is an additive

38
00:02:03,680 --> 00:02:05,960
which is called barrel bright. 

39
00:02:05,960 --> 00:02:07,880
It's like a detergent, 

40
00:02:07,880 --> 00:02:09,040
and it helps everything 

41
00:02:09,040 --> 00:02:10,760
to lubricate as it go along, 

42
00:02:10,760 --> 00:02:12,300
and it stops the 

43
00:02:12,300 --> 00:02:14,660
steel shot from going rusty. 

44
00:02:14,660 --> 00:02:16,480
And we only need a small amount 

45
00:02:16,480 --> 00:02:20,420
about a little teaspoon full.

46
00:02:20,420 --> 00:02:22,820
Place that over there 

47
00:02:22,820 --> 00:02:25,200
and so that's ready to go

48
00:02:25,200 --> 00:02:29,540
and we've got our little ring. 

49
00:02:29,540 --> 00:02:32,660
The top of this barrel is

50
00:02:32,660 --> 00:02:35,940
just a clip fitting.

51
00:02:35,940 --> 00:02:37,820
So it fits on the top. 

52
00:02:37,820 --> 00:02:38,900
And just make sure 

53
00:02:38,900 --> 00:02:42,240
that the whole thing is nice and dry

54
00:02:42,240 --> 00:02:46,600
before you put it onto the rollers.

55
00:02:46,600 --> 00:02:47,940
And also just make sure 

56
00:02:47,940 --> 00:02:49,380
your hands are nice and dry 

57
00:02:49,380 --> 00:02:50,820
before you switch it on. 

58
00:02:50,820 --> 00:02:52,760
So the best practice 

59
00:02:52,760 --> 00:02:56,540
is really to switch on the machine first

60
00:02:56,540 --> 00:02:58,820
and then you put the barrel on 

61
00:02:58,820 --> 00:02:59,960
and then there's 

62
00:02:59,960 --> 00:03:02,320
not too much strain on the motor. 

63
00:03:02,320 --> 00:03:06,000
And as the shot and the barrel roll

64
00:03:06,000 --> 00:03:08,360
over and over, that burnishes

65
00:03:08,360 --> 00:03:10,200
the surface of the metal 

66
00:03:10,200 --> 00:03:13,660
and doesn't wear away the scratches,

67
00:03:13,660 --> 00:03:15,660
it smooths them down. 

68
00:03:15,660 --> 00:03:18,500
So after about 20 minutes,

69
00:03:18,500 --> 00:03:20,680
30 minutes or so, 

70
00:03:20,680 --> 00:03:23,100
when you take the piece out,

71
00:03:23,100 --> 00:03:25,280
it'll be all foamy 

72
00:03:25,280 --> 00:03:26,940
because of the washing 

73
00:03:26,940 --> 00:03:30,200
powder, the barrel bright,

74
00:03:30,200 --> 00:03:32,640
but it'll be all nice and shiny. 

75
00:03:32,640 --> 00:03:34,940
20 minutes is a sort of minimum time,

76
00:03:34,940 --> 00:03:37,160
but you could leave it in for some hours 

77
00:03:37,160 --> 00:03:39,960
and there would be no problem.

78
00:03:39,960 --> 00:03:41,120
Once it's finished. 

79
00:03:41,120 --> 00:03:44,220
Then take the barrel off, 

80
00:03:44,220 --> 00:03:45,680
switch the motor off, 

81
00:03:45,680 --> 00:03:49,200
and then you can either dip your hand in.

82
00:03:49,200 --> 00:03:52,140
You can see it starting to get bubbly now

83
00:03:52,140 --> 00:03:54,080
and pick out your pieces. 

84
00:03:54,080 --> 00:03:56,460
But if they're small pieces like earrings

85
00:03:56,460 --> 00:03:58,160
and little stud earrings, 

86
00:03:58,160 --> 00:04:02,540
then you can pour it into your seive

87
00:04:02,540 --> 00:04:04,440
Pour it into the seive 

88
00:04:04,440 --> 00:04:06,340
and then wash it through 

89
00:04:06,340 --> 00:04:09,400
and but always leave it with some water

90
00:04:09,400 --> 00:04:11,680
and a bit of barrel bright.

91
00:04:11,680 --> 00:04:13,960
Because if the shot goes rusty,

92
00:04:13,960 --> 00:04:16,260
then it doesn't work so well

93
00:04:16,260 --> 00:04:20,320
and it doesn't brighten the things up.

94
00:04:20,320 --> 00:04:23,300
But that's a wonderful tool,

95
00:04:23,300 --> 00:04:26,180
but it's one of the finishing processes.
