Your pop rivet is much lighter than my T-nut/allen screw solution. I assume you used an aluminum rivet. You might have even gotten by with one of those rivet washers (I can't think of the proper name right now). They're about 3/16" thick, which should be thick enough to tap and secure a screw thread. The key is get a seal on the filler hole so the vaporized alchohol doesn't escape though it.<br><br>I've never worked with high temp silicone. How does it compare? The J-B Weld is okay to work with. I used too much and the heat chars the excess. But the seals still hold so I'm not concerned with beauty!<br><br>Of course, we'll see how it truly performs in the field. Next month I'm taking a crew of High Advnture scouts into the woods for what will be a cross-country day hike (see Owasippe BioBlitz for moer info). I'll have my wind screen done by then so I can take the stove with to cook lunch or at least make some tea (how's that for a tie into another forum thread?). I'll post my experiences afterwards.
