  1. That's OK. Sometimes I have trouble remembering it too.
  2. I agree that most any tug is pretty worthless in snow and ice. The ones I make (see my gallery) work well, but they are not really portable.
  3. Hank, You may be taking about me. Indeed, I am still making visors, but not for center post mounts. Don Muncy
  4. I would look for a grounding wire a little loose. Easy enough to use a wire and a couple of alligator clips to make a temporary ground to check (although a PIA to get back there to hook it up).
  5. A trip to the Home Depot brass fitting department will get you a couple of fittings to make a removable plug. Yes, it always aeems a waste to fill a tank with a substantial amount of O2 still in it, but there is no other way.
  6. Geez, you guys make my head spin. I know only slightly more than red to positive, black to negative.
  7. I agree with that idea. It happened to me once. But I think Battery Minders are a good idea. My thought is that, periodically, you should disconnect the Battery Minder for a week and check to see if it will start the plane easily. (Is that a CB's battery capacity test?)
  8. I agree, except I would move corrosion to the top of the list. And I would tell the person doing the inspection, that if corrosion is found, stop the inspection at that point. No use continuing to incur cost.
  9. I don't know how that would work if they charged you with the testing fee. If you are constantly swapping O2 tanks with them, you might wind up with one that needs a test every time you swapped, just from bad luck.
  10. I have swapped multiple times and have never seen a bill for a hydro test.
  11. So the theory is that when fuel is run through the injector, a tiny amount will cling to the bore of the injector when the engine is stopped. The oxygen will then oxidize it, and then fuel flow through it when the engine is run again, will not remove it? I'm not as smart as I thought I was. Thanks for the education.
  12. Thanks for the information. Do you (or anyone else) have an idea of what might have created that clear varnish build-up?
  13. Great for portable cylinders. Not so great with an on-board tank like K models. I have to keep my refill cylinder in the hangar, or carry it back and forth.
  14. I hate to act like a "know-it-all" and I admit that my knowledge has definite limits; but... I know that injectors can get blocked by bits of junk. It happened to one of mine once. But I think that routine cleaning of injectors for a build-up of something is a waste of time. They get cleaned by a blast of solvent (av-gas) on every engine cycle. Has anyone ever seen a build-up in any injector bore?
  15. Don't lose the adaptor for the portable tanks. Soon someone will want you to fill their portable tank for them. Remember that you can never fill a tank completely. It only fills until the pressures between them equalizes. You will have to refill the big cylinder when the pressure goes below the minimum you will tolerate in the plane. You may only get 3 fills before needing to replenish. With a two cylinder cascade system, it gets better, but you still have a limited number of fills available. As to calculating the amounts of O2, I don't worry about it. I keep re-filling until it gets down to my minimum and re-fill. Also, it is very important to remember that when filling, if you hear a "rattling" sound, quickly shut down the tank valve until it stops. That is the sound of the valve on the tank in your plane "bouncing" on its seat, and will quickly ruin it. They are expensive and a pain to replace. The fire marshal in Dallas, will not tolerate O2 bottles in the hanger unless you pay a yearly fee. When he comes to inspect, my FBO folks tip me off in advance, so I can go bring my cylinders home until after the inspection.
