In a twist to my usual
information about French polishing, I thought it was about time to get up to
date and talk about the use of spray guns.
Let’s first take a look at
my spray gun, this is I think a good make, and being at
the lower end of the price scale for this particular company, I paid about One
Hundred pounds inclusive of a trade discount so not that cheap.
As you can see that I have
dismantled it in order to give it a good clean.
This is a must as this
will give you a much better finish from start to completion of your project.
It is very important to
ensure that the nozzle holes are kept clear, and another point to look out for;
is the hole in the top of the pot because if this is blocked airflow will
cease to allow the lacquer to flow freely.
Before putting it back together,
I always oil all the threads and the needle together with the spring and in
doing so; will ensure that all parts operate correctly.
Don’t forget to change the
pot filters, as I have found they soon become blocked and once again the
lacquer will not spray freely, I have often soaked the filters in thinners and
then brushed out the debris, it is amazing just how much stubborn build-up of lacquer
that comes out.
When purchasing a spray
gun, it pays to do the research and try to buy the best you can afford the
model I have, is tricky to get spares for as I found out when the connector
thread at the bottom of the gun became loose and then cross-threaded itself, I
was lucky to obtain a replacement so all ended fine for me.
I do not wish to advertise or
endorse the above spray gun; it is for reference purposes only.
Once again hoping this
will be of use to you.
Feedback is always
welcome.
