  1. I found a lot of evidence of critters using my GT6 not so much as a restaurant, but as a flop house. The pink stuff is insulation from the house. Ed
  2. When elemental iron combines with a phosphate ion, it gives up electrons. That's oxidation. Ed
  3. With phosphoric acid, I suspect that most of the rust on the steel surface is converted to iron phosphate that either falls away as a precipitate, or forms the dark "smut" left on the cleaned surface. The phosphate that adheres to the steel surface is likely oxidized from the elemental iron. Some of the smut is also probably carbon (and maybe other elements) from the steel. Ed
  4. Citric. Not organic, but phosphoric would work, too. Ed
  5. Very nice, Roger. I always thought that Triumph sort of cheaped out on the Spit/GT6 dashes. Ed
  6. I've heard of situations where the upper widemouth part of the column becomes loose so it can rotate or even come off. I think it was originally fastened with a couple of spot welds. Some epoxy might fix it. Ed
  7. By weight, my first guesses would be oxygen or carbon. But since you said it's surprising, it must be something else. Iron? Ed
  8. Being in the States, i use McMaster a lot, but in this case I found these shims for the spacers in my GT6+. The spacers are home made, but that shouldn't affect the shim size. Ed
  9. Here is one thing that can make the rocker ratio vary a little over it's arc. The contact point on the valve stem moves outward slightly as the rocker foot rolls on the downstroke. The rocker geometry can be manipulated somewhat to make that contact patch narrower. Ed
  10. I have a tool similar to that one, but i put it in an arbor press instead of whacking it with a hammer. Works well, is more controllable, and seems more civilized. Ed
  11. For anything that is not an outer panel, I sand blast. There is no simpler, more effective process to remove paint, rust and most other material from metal. For outer panels with a lot of shape or curvature, I do the same. For more flatish outer panels, it is usually a Methylene Chloride stripper outdoors, and then abrasive wheels. The blaster might be necessary to get into some tight areas. Ed
  12. I apparently don't know how to include an image in a post.
  13. I did the Four Seasons valve on my TR6. It is a much better part than the original. Nick is correct, though, the hose barb is for 5/8 ID hose as opposed to the 1/2 ID hose on the TR. The hose will go on, though. Ed http://bullfire.net/TR6/TR6-77/IMG_2760a.JPG
  14. I typically bench bleed my MCs, but I do it on the car on install. It just involves filling the reservoir(s), and installing temporary tube(s) on the MC outlets which divert fluid back to the reservoirs. Pump the brake pedal until there are no more bubbles. I don't think it is necessary to bench bleed, but it seems to make the system bleed go a little quicker. Ed
  15. Yes that was exactly my point, John. Surface area would be much more indicative of cooling capacity than matrix volume. If we can assume a relationship between a cubic inch of matrix and its surface area, then volume could be a proxy for cooling ability, but i didn't know if that was a thing. Ed
