Hand Powered Vacuum Chamber V.2

After the first version, I was running out small yogurt containers to use and the larger pots would not fit into it.

So when I came across this Ice bucket at a car boot sale and being larger, bigger and much more stronger than previous acrylic tube, I thought it would be a perfect upgrade.

Materials used: (Please see version one for links to some of the common materials used)

• Double walled Ice bucket (I believe it is made of strong acrylic material)
• Nozzle of a silicone sealant
• Base for the ice bucket (any flat, smooth, strong material with at least 3mm thickness will do)
• Silicone rubber
• suction pump
• one way valve
• Clear PVC tubing
• Circular grill (as a container for the silicone rubber)

Tools used:

• scalpel knife
• Dremel drill with cutting and drilling bits
• Tapered reamer
• small torch flame
• Pair of scissors

CAUTION: When operating electrical equipment, always follow manufacturers safety instructions to protect yourself from possible accidents.

I drilled a hole for the silicone nozzle and again, the ever useful tapered reamer came real handy.

Because this was a much bigger container, I had a little bit difficulty finding a base for it. In the end managed to find this copper plate tucked away in my shed that I got for pennies from a carboot of previous years. Its diameter was larger than that of the bucket opening which was exactly what I was after. So now I had to create some kind of air tight barrier between it and the ice bucket. To do that I thought of using silicone rubber that I already had and the next task was to create a circular wall to pour the silicone rubber into.

As it happens, I had this circular metal mesh ring that my workplace chucked away when they've upgraded the light fixtures. Because it was few cm's too big, I cut the excess with a dremel and joined it with an aluminium insulation tape.

After securing everything in place, mixed and poured in the silicone rubber.

All looking good!

Coming Soon!!!!!
