Inverted flight fuel tank mods

Today I decided to go back through the fuel tank plans to double check if I had missed anything. It seemed like I had everything covered except I couldn’t find any mention in the instructions on how the fuel lines need to be modified to allow for inverted flight. However, the drawings do have some … Continue reading

All tank parts dimpled

As luck would have it, I found myself back in the shed twice in the same day. A rare and joyous event nowadays. So to make the most of the opportunity, I decided I was going to try and dimple everything that needed it in a single session. I set up my C-frame in between … Continue reading

Finished tank deburring

Today I finished off deburring the holes on the left tank, ribs and baffles. I also deburred the Z-bracket holes. Nothing really exciting but here is a photo of all the pieces after I’ve deburred them. I’m now ready to dimple everything. Build time 2.5 hours.

Drilled Tank Drains

I started looking for my fuel tank drains. I new I had seen them somewhere but I couldn’t remember exactly where. As I was going through my wing parts I discovered another pair of T-410 nose doubler plates. Hmmm… I didn’t remember the plans requiring two of there plates so I went back and checked … Continue reading

Fuel Cap Drilling

After looking at a couple of other builders’ blogs, I confirmed that the deluxe fuel cap flange is what I need to use in place of the standard flange shown in the plans. Looking at the cap flange, I noticed that it was curved to match the curvature of the skin. I also notices that … Continue reading

Riveted tank sender hatch rings

Today I riveted on the reinforcing rings and nutplates to the inboard ribs of both fuel tanks. I had already clecoed everything in place so I fired up the compressor and started riveting. I found that it was a bit too awkward to use my squeezers so I had to use my rivet gun. After … Continue reading

Fuel tank inspection holes

I’ve been thinking about how to cut the large circular inspection holes in the fuel tanks. I don’t have a fly cutter and wasn’t able to source one locally. A few of the other builders have trimmed these by hand and filed them to size but I wasn’t keen on this approach as it sounded … Continue reading

More on the right fuel tank

This post covers the past 2 weekends. Last week, I drilled the skin to rib holes to the correct size, drilled the skin spar attach holes to #19 size, and countersunk the spanwise holes on the tank skin on one side that join to the baffle plate. There wasn’t anything really exciting or different to … Continue reading

Onto the right fuel tank

Last Sunday I had a spare couple of hours so I snuck into the shed and got to work on the right fuel tank. With the left tank disassembled I had recovered a large number of clecoes which I used to fit the right wing tank onto the right wing. I then match drilled the … Continue reading

More work on the left fuel tank

I’ve been away on holidays which included some time in Singapore. I had the opportunity to check out the new 737-800 flight simulator there called Flight Experience located near the Singpore Flier ferris wheel. I did a take off from Macau, a touch and go at the new Hong Kong airport, and a full stop … Continue reading
