Hello and welcome to todays video, where Im going to show you how I made my drying
And you need a drying chamber when using oil varnish, like the varnish assortment 1 from
Joha which is the sponsor of todays video.
But first we have to do some shopping.
In the do-it-yourself shop you can ask them to cut the wood and they cut it very precisely
So, shopping is almost ready, unfortunately they didnt have everything, so I have to
go also to another shop.
Here we are, shopping is ready
I bought six parts of wood for the six sides of the chamber, a so called piano hinge which
is not a new one, I had already one so I didnt have to buy this one, the same for the net,
the same for the aluminum foil, I bought some glue, a ventilator, a mirror ball motor,
a switch, I had a power supply, and a plug and some other small parts
Now I have to put everything again in the box the only part that Im still missing
is the UV lamp, I ordered it this morning, it will be here by the time this video is
almost finished, anyway, I have to say that you have to be very very careful, the light
that has to go in the chamber is UV-C light which is very dangerous for your eyes and
also a bit for your skin read the disclaimer that I put in the description and be very
careful also with the tinkering of electricity, part of the chamber will work on 220 Volt
in Europe or 110 Volt in the US, be careful not to kill yourself.
I will start with the back side which is the smallest, its this one, lets put the rest
At the back side I want to put ventilation, this part, and this will blow fresh air into
the chamber, for two reasons: the first one is to cool it a bit down, as it is closed
and the lamp will be on for several hours it might get a bit hotter, and second is that
the flow of oxygen helps the oil varnish to dry.
So what I have to do first is to cut a hole in the back and I will also make wooden sides
where Im going to fix some kind of filter, Im just going to use some cloth and this
Always use protection for your eyes and ears.
Now the ventilator can go inside, but I wont put it on its place, firstly I will glue at
the inner side now of the chamber aluminum foil, which is going to help reflecting the
light of the lamp towards all the sides of the instrument.
As you can understand this has to dry so I will have to leave it for a little while and
in the mean time I would like to tell you something about our sponsor and their oil
When you order the Varnish Assortment from Joha, you will receive this box where you
can find everything you need to varnish your violin or cello.
And when I say everything, I mean everything!
From the sandpaper to finish your instrument, until the High Gloss Cleaning Polish to give
the finishing touch to the varnished instrument, including also a brush and a sponge to apply
the various products.
You can order the set in various colours, from yellowish and amber, until red-brown
Although this is an oil varnish you dont need a drying chamber to use it.
In the box you will also find instructions on how to use it and these are in English
or in German.
As soon as this video is finished I am going to start making a review of this varnish, I have got
a guinea pig violin where I can try everything, this video will be up next month I hope, SUBSCRIBE
so you wont miss it and dont forget to have a look on the website of Hammerl for
more information about this set and the other ones that you can get.
As you see the aluminum foil is glued now at the inner part of all the pieces of wood
so now I can start mounting all the equipment like the motor, the ventilator, the switch,
and the light.
We will start with the motor, which is a very simple mirror ball motor, not so expensive,
they do 3 RPM which is more than enough.
To make the hanger for the motor, to hang the instrument in the chamber I will use 12mm
plywood and I will cut it like that.
Now I can attach the motor on the top part of the chamber.
On the tope side of the chamber Im also going to mount this switch which is going
to control if the door is open or closed, when you open the door the light goes off
and you dont have any damage to your eyes.
Be very careful with the UV-C light dont forget also to read the disclaimer that I
have put in the description.
The top side of the chamber is almost ready, the last thing that I want to do is to put
these reinforcement pieces of wood, close to the edges where the other sides are going
to be fixed.
The top is done, I will put it away now, and we are going to work now on the left side.
At the left side Im going to fix the lamp, it will be fixed here, a bit like that and
I also have to fix the cable that is going to the switch.
Now I want to run the wire from the switch on the top to the light on the side but to
be able to measure and cut the wire at the correct length I will fix the top to the side.
For the time being its OK like that I still have to put another wire from the lamp to
the outer part of the chamber where the plug will be but first I want to glue the backside
on its place.
Three sides are already on their place and now I can glue the right side on its place and
then the bottom.
As you see the chamber is ready, I used an old cello peg to make a nob, and at the inner
part I also put a magnet to keep the door closed, and now I can finish the wiring and
then we are done!
For the lamp I already had made the first part of the cable, from the lamp to the switch,
now I have to use this part to go from the lamp to the plug.
And finally I can solder the power supply to the ventilator, put the ventilator on its
place and then put the filter over it.
I will use this net and this piece of cloth to make the filter and I will nail it in place
And now I can put all the plugs from the light, the motor and the ventilator to this one so
I need only one plug to use it.
After some hours of work, the chamber is ready, you can hear it working, a little bit, but
I will show you.
As you see the motor is turning and the ventilator is working and now Ive put a lamp inside,
just a normal one so I can show you and I dont get blind, but if I close the door
and push the switch the light goes on and as soon as the door opens the light goes off
As I said during the promotion I will use the chamber with the varnish of the sponsor,
of Hammerl, with a guinea pig violin that I have got to review the varnish and also
to see how effective the chamber is.
So dont forget to subscribe, I think that I will put the review next month if I have
time enough otherwise a month later dont forget to subscribe, like if you liked this
video and I will see you next time again.
