Hangar at Heffley House

45×45 steel building, October 2024 work.

 

5 inch foundation would end up 1 inch below the lower perlin.

Or 6 inch would cause the perlin to sit on the concrete.

1 each, 18 foot door for cars . Each door will want a small bevel.  sloped.  Because the doors slide sideways.

 

One 40 foot door.

 

In our home we did DIY terrazo.

 

Concrete finish (polish) will need to allow me to grind the top layer off, and seal the concrete for a terrazo look.

 

 

 

 

The galvanized flashing will be discarded, and J channel installed, to cause the outer edge to have a “brick ledge”

Floor is 5 to 6 inches below perlin.  Road base is not perfectly flat.  Varmit ledge on outer perimeter? Beam at both doors? Beams in the hangar?  Expansion joints?

 

The walk through door may be installed too low.

5 inch foundation would end up 1 inch below the lower perlin

Todd Heffley accomplish.

Empty hangar bare.

Remove walk in door and door frame.

remove 18 ft garage door.

Remove 40 foot hangar door.

Remove 12 in flashing at grade.

Install Jtrim at lower edge of R-panel.

Contractor accomplish:

Dig varmit ledge at exterior walls. Dig beams at 18 foot door, and 40 foot door.

Dig cross beams.

Rebar as per quote.  5 inch floor to polish finish, ready to grind for terrazo. outer form boards will touch the outer edge of Jtrim

Haul off all construction trash.

Leave clean fill on site?

Ramp at 18 foot door.  1/4 drop over 6 inch run, inside of 4 inch pier.  Sloped grade 18 feet east.

Ramp at 40 foot door.  1/2 inch slope over 12 inch run. Starts 6 inches inside of inner edge of 4 in square beam.

 

At walkthrough door, a landing aproxx6feet x 6 feet outside door.

Fresh water service pipes.  Remain in place.

 

 

 

 

 

 

 

Level exsisting road base

dig beams

slope 1/2inch x 6 inch at both doors

beam under both doors

varmit ledge, 10 inches around the outside

Not sure how to handle walk-in door. Too low?

4 inch or 5 inch

smooth finish

5000psi?

no expansion joints

tECHNOLOGY

PCB production

After making hundreds of boards with PCB Express…. we grew out of them. They offer a very easy to use interface, walled garden approach. expensive boards.  Something like 5 x the industry average.

 

I finally found EasyEDA.  It is simple enough for my pea brain to operate.  Lots of libraries built in.  3D view. Direct to JLCPCB to fab  boards.

 

 

We shall see how the quality works out.

F900 Troubleshooting

F900EX Generator traumas

This is an old presentation i set up.

I thinkmi cabbaged some stuff from flcon, and added some art.

Old notes:

Old troubleshooting notes on a long-legged problem: engines running:

  1.  Check for Bleed leak blowing on GCU.  BE very carefull if you elect to run the AI on the ground.  !!!!!!APU BLEED OFF!!!!!!, slats extended.    20 seconds ground test max. leave the slats out to cool.
  2.  Test “E” ground quality.  Fluke on volts.  Black lead to airframe ground, red lead to GCU Black test point.  Very small voltage~ .1v.  less is better
  3. Volt drop on line contractor.  Fluke meter on volts.  Red lead on upper contactor, bottom big bolt, black lead on same contactor, upper big bolt. Very small voltage~ .1v.  less is better.
  4. Ripple test.  use fluke MIN/MAX.

Run each test with only 1 gen online, 50 to 100 amps load, try to hold conditions quite similar for each test.

some other thoughts:
look at big E terminal, small 20awg terminal.

double check each  GCU voltage. Is it stable at 28.5? is it stable with load? is it stable with RPM change?

select cockpit red switch to off.  Is the voltage of a running generator, cockpit switch selected off,  .7v to 1.0v at idle? this checks the quality of the permanent magnets inside the Generator.

ASSURE that NO ENGINE GENERATOR  has a cooling fan installed. (possibly a borescope through the black sooty outlet.) or it mat be necessary to unbolt the cooling exhaust.

Initial problem definition:

#3 Gen Light occasionally, Much troubleshooting. Gen 3 amps tend toward zero. #1 seems to “take the load”

 

History:

#3 gen troubleshooting, #1, #3 gen shunts…..?Removed?

Westwind pressurization problem

 

Overview

 

westwind pressurization

 

 

 

 

 

 

The valve opens correctly with shop air applied, and the controller  disconnected, and slight vacuum applied to control circuit

 

 

 

 

Front valve will open when control i connected straight to the pneumatic relay.

 

 

 

Ground prepress seems to work correctly

 

 

 

 

Aircraft pressurizes hard on the ground, straight to 3 psi at idle.  Fwd valve will not open via the controller.

 

Turns out the limit valve was failed.  It had opened because the pilots got the cabin to 17,000 feet.  Then the brass seat fell out of place.  Then valve leaked from then on .

 

 

 

 

Removed failed altitude limit valve PN 102466-1  SN 88-2322.  Installed serviceable valve received on form.   PN 102466-1   SN 17-1898

 

 

 

 

 

Removed failed anti-ice pressure reducing valve PN 38E59-1D  SN 2907 -U. Installed Ovrrhauled valve recieved on AVITECH W.O. 1021932 PN 38E59-1D  SN RF3502.
