Thanks, Pete. I did learn a lot from this pour. A lot of information here for sure. And it is difficult to sort through it. The first section of the pattern was indeed intended to be a blind riser. On my first glass pour I had the runner entering below the riser and exiting below with a dam in between. That indeed slowed the flow. My normal way of gating now is to gate perpendicularly off the runner like this. The runner directly to the open riser will have to slow the flow through the gate into the blind riser and pattern. I find a small plug works very well. It can't float, and you can make it short to burn through quicker, but I like it about 3/8" long to give me more delay. I also like the smoke flushing oxygen out of the sprue and runner ahead of the metal front. I'm not set up for degassing and am delaying it now until I figure out whether it will benefit me. If I see no or very few defects after melting dirty ingots then the value seems diminished. I'll be interested in seeing whether I can meet Kelly's challenge of a leak free tube with dirty ingots as my melt source.
