Degassing tool
Posted: Thu Dec 08, 2011 9:10 am
Here is what I set up for degassing tool and making packets to load into it. Also an idea for a tool that might work out well. Will put it together and report back on how it does.
The new tool I will make is a piece of 1/2" pipe about 2" long with about 1/2" cut off the lower end. These two pieces will be welded to to large washers that are tacked together with a very small gap between them. The top of the tool will be blocked/sealed by the tool handle. My thought is the gap should be small enough to keep metal from flowing into it yet big enough the gas will escape. The piece of pipe below will create some small back pressure to force the gas through the small gap.
The hope is that this will do a couple things. Number one is to make lots of small bubbles out of the large bubbles I get from the current tool. Secondly disperse the bubbles over a wider area. The tool above tend to see the bubbles coming up alongside of the handle and doesnt seem to cover much of the melt unless I slowly 'stir it around while the degasser is active.
