Making relief-cut wine labels

This shot shows wine labels from the mid 1990s and the equipment used to make them. They are printed onto either gummed or self-adhesive labels from inked printing blocks. The blocks are rubber, mostly erasers, although the large block here (with "Apple" on it) was a rubber fender block from a van or truck.
  Wine label making

Single-block printing

This block has been used twice. Originally it had the words reserve and the date (1997) on it. These were removed when it was used in a following year.

These labels were produced from it (not the Elder reserve 96, that was produced by photocopying an original drawing and then hand-colouring it.)

You can see the two variations - with and without the side text.

Wine labels

Multi-block printing

These labels are proofs to check alignment. The green apple" block was printed first, and the black smaller areas printed with a number of smaller blocks. The patterns are either oak leaves, elderflowers, the year (1995) or "Dry".

This is the main printing block. It's about 10cm by 8cm

Here it is alongside labels printed on the first level only using it...

This is a small scale version of an animatronic maggot, based on a human sized one I saw at a festival in Arnhem once. That freaked and groaned impressively as it ground round, powered by a washing machine motor

Making an Arduino power supply cable look wooden

Gluing wooden casings onto plugs Wooden power unit for Arduino head
With nice wooden plugs an ugly black plastic lead is not really what anyone wants!

The black lead on the left was revamped into the lead on the right by sawdust coating it using latex as a flexible bonding agent.

Latex and sawdust forms a composite material which is much physically robust than either on their own. The latex provides flexibility and the dust gives bulk and resilience.


Pouring latex
Liquid latex from an art supply shop was used, without any thickener adding. It uses ammonia as a suspension fluid which does smell rather strongly. Use in a ventilated space!







Dipping cable in latex
Latex was poured into a shallow container









Sieving sawdust
Sawdust was sifted to get a fine powder.









Making a wood-effect power cable
The sawdust was dusted over the wet latex.









Wood-effect power lead
This was left to dry, then the process was repeated.

Eventually after three coats it ended up looking rather tasty and root-like!

Adding wooden plugs to the power unit

Cracked wooden casingThe casing for the power supply to the wooden head has cracked. This was pulled apart completely on the crack, and glued back at the same time as gluing the casing onto the power unit transformer.

Here it is being held temporarily in the vice, while a cramp is attached.









Wooden casing for 5V end power plug
A conical casing for the %v end of the power lead had been turned, which had also cracked. This turned out to be helpful, as it was the easiest way to fit the plug








Cramping wooden casing while gluing

A pair of locking grips was used as a cramp to hold it while the glue set.












Gluing wooden casings onto plugs




Once glued and cramped, they were let to dry

Creating a new oak casing for the new power unit

Testing animatronic head with wooden mains plugThe head finally has a working wooden power plug.  The first power unit was burned out by soldering a new lead on before it even got the oak round it!

The second stopped working after it was encased in oak. It was not obviously damaged externally. It is likely it was broken inside by vibrations from the sander, as the plug was in situ, when it was subjected to some serious RPM.






See below for the steps undertaken to create this...

Routing out void to fit plug into wooden casing

Note the guide rail cramped to the bench. This is a guide for the handheld router to keep to a reasonably straight edge

Checking the plug fits with both halves of the casing in place.

As the last unit was killed by vibrations, this one was to be finished without the unit in it though






Sawing off screw head to make guide pin
To do this, the two halves of the casing needed to be sanded whilst kept aligned. The plug had done this in the previous attempt, but was not in place in this version.

Tow screws were inserted in one half of the casing to create guide pins to keep the halves aligned whilst sanding.

The guide pin after the screw head has been removed. This is to fit into a hole in the other half of the casing. (there are two of these)

To mark the other half of the casing, the two halves were aligned, then pressure applied in the vice.

This created an indentation, to mark where the alignment hole needed to be drilled.

New power supply

Having screwed up three power supplies so far, here is the new one...

5v 2.5A power supply

Here's the previous plug, with delightful casing, but defunct supply!

I believe this time it was the vibration from the sander breaking the innards of the supply :(

Making a wooden power plug

Having finished the head, it seemed poor to use a plastic plug. What better than a wooden plug?

Initially I started trying to take apart the plastic casing of the transformer, which looked like this. Unfortunately, the supply failed, which I believe to be due to fusin printed circuit connections with solder while trying to solder a new lead onto the circuit board. FAIL!
What's inside a 5v power transformer
Having destroyed one supply, another was found in the shed. This was fitted up with an oak casing

This was made from two short pieces of oak plank, with a cavity taken out with an electric router

Wooden power supply casing

The two halves together look like this

These are not flush.  To do so they needed to be sanded together as one piece. This would only work once glued together. Here theyare in the vice with cramps attached (one traditional iron screw cramp, and one metal/plastic ratchet cramp)

Head is finally finished...

Finally the head is just about ready...
Reading lamp head (front)
I amused myself looking up the original drawing....

Here's what's inside the face...

...and the arduino control circuit under the base...

All that really remains is to make the power supply...
