It may work, but try it first. Assumption is the mother of all f--k ups

Test a couple - try coating one in epoxy, put in RED can of gasoline, let sit for months

find a drug dealer with an accurate scale and weigh before and after test

Drug dealers have the best scales, i know, they lift them from laboratories

Really Dust?......hmmmmmm tell OFFICER Barber everything you know about these drug dealers you are so cozy with.

However, I do have access to drug scales.....had to use it last night (late arrest that kept me from the hangar).

I always figured, perhaps nievly (sp?) that the nickname "Dust" refered to sanding dust.....but NOW I'ma thinking it may be some other kind of dust....or, maybe a white power?????????

Hee hee hee.

All the best,

Take care that the hydromometer has not been used already. If it has, you might put a tiny amount of nasty acid in your fuel system, just enough to wreck a nearby metallic part.

Labs?!?! All they have to do is go to Fry's in Houston. I never seen so many 200 gram scales in one place in my life.

Chris just see who's buying those scales at Fry's...

Default Vance Atkinson Fuel Sight Gages Installation

Can I do the layup on my fuselage sides without having the fuel gages from Vance Atkinson on hand?

I ordered them a while ago, but paypal screwed up and I forgot to re-order them.

The text in the plans (Chapter 5, Page 3) say "...dish the depressions for the fuel sight gages (Fig. 7, sec. F-Fl. After dishing, apply a 2" wide strip of shiny, box-sealing tape to this area so the glass will not bond to the foam. In a later chapter, the foam and tape are removed from the outside, so the fuel may be
viewed through this translucent window." T

Then, in a note at the bottom of the page, the plans add, "Note: If you plan to install fuel sight gages per Vance Atkinson (or equivalent), you will need a flat area 2" wide (Fig. 7, sec. F-F) and 7" deep (Fig. 7)".

This seems simple enough. If I understand this correctly, I just dish out the foam with dimensions of 2" wide by 6/9" (matching the dimensions of the fuel gage) and mask it with tape.

The questions:
How far down from the top of the fuselage sides do I place the fuel gages?

At first, I incorrectly thought that the plans indicated that the fuel gages end up partially tucking under the yellow-foam spacers. This made no sense. This doesn't seem right to me, nor did it match photos I recall seeing from other builders.

So, can someone confirm that the bottom of the fuel gage is 9 1/2" from the top of the fuselage sides. (7" fuel gage butted up against the bottom of the 7 1/2 in tall spacer section "CC")?

And, while on the subject of this area of the plane... How accurate does one need to be with the carving of these spacers (yellowish foam)? I don't think I did the greatest job of carving and sanding the spacers to exact dimensions.

The plans (and the airplane) are at the hangar, Dan, so I can't give you exeact measurements. Hopefully someone will. To me the gauges look a bit high in that drawing. The bottom of the gauge is just above the top of the back armrest. The gauge spans the height of the strake (obviously). Look at the plans and drawings to work out where the bottom of the top skin and the top of the lower skin will go. You want the lower hole in the gauge level close to the top of the lower skin. Also - make the flat area a bbit more than 2 inches wide to give yourself some room.

Disclaimer - its a long time since I fitted the sight gauges.

The gages in the drawing do look a bit high. Odd because the drawing I have included is a section from the actual plans. (Chapter 5, page 3, Figure 7, right portion)

Thanks for the note John. It seems like the process of typing out a question in a manner that would be clear to others ends up answering the question most of the time. Many times I have started typing out a question and then realized that I had it figured out before I could click "send."

Are you going to order the gauges with the LED lights or without the lights? I need to order mine, possibly later today. Just not sure if its necessary or important to have the LED lights. They would be nice. Are they worth $30 and the extra wiring? I guess its up to the individual.

Well, nice and new and in daylight in your shop - they are easy to read.

The ones I have seen installed seemed to darken some with age, and at night, ifin you want to see em, light em

Anyone else planning to skip the sight guages? From what I've read, they are difficult (impossible?) to see clearly in flight, and if you only use them on the ground, just check tank level at preflight.

A little difficult to see the left one, but possible. The right one is EZ to see. I use them all the time - there's nothing quite as assuring than to actually SEE the fuel in the tank. My vote - Put the sight gages in.

I think NOT seeing fuel in the cockpit is comforting... I'm thinking fuel guages would be nice.

I'm doing both. The plans guages, (Vance's w/ lights), for a dependable backup, and fuel guages up front for convenience.
