The Lightblade Learning Lab with Russ Sadler
The Lightblade Learning Lab is a series of videos that Russ did for Thinklaser Limited based on using the Lightblade 4060 Laser Cutting and Laser Engraving Machine. Thinklasers Lightblade 4060 has a 400 x 600mm bed size and was supplied with a 60W EFR laser tube. In this session, Russ creates a laser cutting project in order to protect the keyboard of his Ruida control panel.

Welcome to another Lightblade Learning Lab
00:18
today for a change it’s not going to be very technical it’s not going to be very
00:23
difficult and it’s not going to be very long. If you remember the last time we’ve
00:28
had a session I pointed out that this keyboard here is getting a little bit
00:31
tacky and I needed to protect it as I had done on my other machine over
00:38
there and so what I’ve done I’ve been away and I’ve designed a keyboard
00:44
protection scheme for this particular machine now it’s different than the
00:48
style that I used on my China blue machine but the essence of it is exactly
00:51
the same. We’ve got a little flexible plastic film here which is going to
00:56
cover and protect the keys now we’ll go straight in and we’ll start cutting the
01:03
design that I’ve already prepared and then we’ll go through the manufacture of
01:07
it and you can see how we fit it. We’re cutting this keyboard out of three
01:12
millimeter thick material and I’ve got my air assist turned on and I’m
01:19
going to turn it roughly half off because I don’t want too much air for cutting
01:25
acrylic. just some
01:57
Well there’s the two pieces that we need just rip the plastic film off

02:08
okay so the first thing that I’ve got to do with this is to put a M5 tapped hole
02:14
through there very easily and I can do that with a tap wrench or as you can see I’m
02:18
using a drill chuck. Now I happen to… I’m using that size you can use any size you
02:24
like but I happen to use that size because I’ve got some I’ve got some very
02:28
short M5 screws they’re six millimeter long and we’re going to put that piece
02:34
there like that and then we’re going to put this piece here like this
02:43
I hold the two pieces together
02:52
with the screw like that so now we’ve got an invisible cover sitting on the top there
02:58
at the moment there’s nothing in there but what I’m going to do I’ve got I
03:03
think it’s probably polyester film and it’s about 0.2 ~ 0.5mm
03:07
thick and it’s the sort of thing that you get on a presentation box
03:14
this came off a box of Christmas cards and I was sensible enough at Christmas
03:19
to think ah I might have a use for that and I kept it so that would be my
03:24
protective film that’s going to sit underneath this keyboard frame that I’ve
03:28
produced here and the frame can’t go anywhere because it’s locked around
03:32
these two buttons that we’ve got here so the positions of the buttons on your
03:39
machine might be different but hey it’s the idea that you need and I shall put
03:43
this DXF file onto the Thinklaser of website so that you can use it as a
03:49
basis for starting, starting your own keyboard protection. Right now I’ve kept
03:54
this the correct way around when I’ve taken it off because what we’re going to
03:58
do now is to apply to the back of it some double-sided industrial-strength
Transcript for Laser Cutting Project – Keyboard Protector (Cont…)
04:04
tape now this is Taser four nine six five which is a very high bond strength
04:10
industrial tape I’m gonna stick it round the outside of the frame there okay no
04:18
it’s a matter of trimming it off neatly all the way around
04:29
well there’s that double-sided tape on there
04:33
so now we’ve got to peel that off right so there’s a double sided tape peeled
04:40
off but I haven’t cut the hole in it at this moment in time that’s going to be a
04:43
little bit tricky so I’ll leave that till after I’ve attached this so we
04:48
might as well just pop this on flat like this
05:04
attach it on nice and strongly get rid of all the air bubbles
05:22
so as you can see it’s not difficult to do this it trims out very easily with a
05:29
knife okay so I’ve just created that hole out
05:31
with a drill and we’re all ready to go so the first thing I’m going to do is to
05:38
make the keyboard like new by peeling off the protective films and there it
05:48
is back to absolutely pristine condition
05:54
we shall now pop this on oops wrong way
06:01
we’ll pop that on
06:08
we’ll put the screw in and if and when it gets a bit mucky
06:15
well next Christmas you can get another piece of film and make a new one well
06:24
this is definitely the star of the show today but I thought I’d try and get in
06:28
on the act as well just so that I could say cheerio and I’ll see you next time
