Re: Perpetual login?

<t>While the internal server error message is gone for original posting, it remains or returns every time you edit a post and then send it out again. I often edit some of my longer posts ten or more times before I get them right, so I should know. Yes, I like the fact that I don't have to log in eve...

Re: Ceramic to steel sealing ??

<t>FYI pure elemental Indium is a superb sealant. It wets glass, ceramic and most all metals. It is applied in molten form and brushes on with a glass brush. You can apply it to clean ceramic and glass in this manner. Thus, indium can join glass to ceramic, ceramic to metal, glass to metal and even ...

Re: >>>>>> great demo fusor <<<<<<<<<

<t>Watch out! I could see the weak point and noted it.<br/> <br/> In a demo or real fusor this grid needs a longitudinal band or some such thing welded in place!<br/> <br/> The entire mass of the grid is held aloft by the bottom most turn, remember. At white heat the hole mass would sink or tip over...

Re: HV Meter tutorial

<t>Tom,<br/> <br/> As I noted in my post. Some, NOT ALL plastic meters can become electrostatically charged and stick. Top brand, large panel meters by Simpson, Weston and others are specifically designed to NOT have any such problems. This is accomplished by careful selection and treatment of the p...

HV Meter tutorial

<t>First, Analog meters are +/- 5% at best!! PERIOD<br/> <br/> Second, check all meters out prior to use.<br/> <br/> Third, never use a meter to measure HV that is less sensitive than 100ua full scale. The following meter movements are OK 100ua (10,000 ohms/volt), 50ua (20,000 ohms/volt and 20ua (50...

Re: What to do until the fusion jackpot hits

<t>If anyone thinks we are not still at step #1, they are severely self-deluded. We are at about 0.26 of #1.0 with the last.74 of #1 looking awfully hyperbolic. Still, we can't tell just yet.<br/> <br/> There is, as of yet, no known continuous process of classically thought of HOT fusion which man c...

Re: On to every parade a little rain must fall. Pt 2

<t>It is not only cleverness by the amateur experimenter, but something that dwells within that spurs one on.
