Glass Thumper

Here we have a glass thumper made from a brand new pickle jar.
The jar is not a heat treated jar. If used sensibly it last for years. I use one myself and do not have any problems.
Let it heat up naturally and cool down naturally no heat shocks and it will be fine. The dimensions are in the photographs it is around the half gallon mark or 2.2lts. I also have a couple of stainless steel thumper for sale. Some stuff is on eBay but it will be more expensive. The main feed in and out is 15mm. The top of the jar is a 28mm tee with a 28mm union connection . It may be necessary to zoom in to read the measurements.
