Barometer...A quick look at how I removed airlocks from the mercury column

See additional links below to other videos on this topic. In this video I show you a little bit of how I cleared airlocks from the column of a mercury wheel barometer, it's a bit of a 'taster' so if you like what you see you might have the patience to watch the two 15 minute videos I made covering the repair of the instrument. I'm not saying what I do is right; I couldn't find any videos that dealt with these problems so I made these videos to show how I chose to deal with the problems.

Thanks for watching.
Kind Regards ... Andy
