Vintage style Wooden Case for fine grid IN-14 Nixie Tubes Clock

All of our Wooden Cases are handmade and produced by the craftsman from our own team.

He is experienced carpenter and have a longstanding work with wood of over 30 years.

We use a maple, alder and oak for our Wooden Cases.

We approach to process of preparing the material with big responsibility.

This process includes scrupulous selection, drying in at indoor temperature of about 25 celsius for a 60 days.

Some other craftsman use fast drying in special chambers for only 8 days but are not.

Long drying gives better material quality.

Then all the details are made on the joinery machines.

And then final crafting is done with tools individually so each detail is a handmade.

Then comes the varnish coating in four stages during next 14 days.

This gives the best result in coating of every detail.

Also it is worth mentioning that all decorative plates of the Cases are made of Stainless Steel with laser engraving.

All the control buttons and switches of the Cases are also made of stainless steel.
