Wizzy Mixer

Another Wizzy Mixer failing.
Same as last time, stripped it, cleaned it, lubed it.
Readjusted the bearing sleeves.

Wizzy Mixing again !

Electroscope

Lesson learnt. Working with Gold Leaf is a total  #@!  of a job...

Needed to fix two Electroscopes.
There's a tiny piece of gold leaf about 2 atoms thick, glued at one end to a metal probe.
I had to cut new leaf and stick it to the probe. Its a nightmare to cut as it just tears.

Much swearing later, I got it done :-)

Wizzy Mixer

This thing heats and mixes liquids / chemicals by whizzing a metal bar around via Magnets underneath.
Its whizzer was stuck.
I fixed it.

Melting point kit

Fixed.

This thingy had glass and corrosion stuck in some VERY tiny tubes in a brass heating block.
Works a treat now :-)

Tested it afterwards and the heat got to 240oC.

Obviously I burnt myself on it. :-(
Here's a FLIR image to see the heat. It also shows the heat travelling up the thermometer.
