Ah right, so you have removed the gear, but can't get the snapped off plastic out of the shaft?

Completely agree. The number of "JB Weld" answers is saddening.

The answer is always something much better than an epoxy glue, or tape that leaves residue.

If the the pin has snapped, it won't be aligned with the snapped piece, which is why you cannot remove the pin. What is stopping the gear from sliding off the shaft now that the pin/key is broken?

What does it look like? I'd not take any answer here seriously if they haven't visually seen the problemo.

Thank you very much. I very appreciate your time to help me understand.

Right. So photons can more accurately be described as sine wave components/properties of waveforms?

Thanks for the answer. I think it highlights some holes in my understanding though.

While we do mostly think of AM and FM radio transmissions; we can pass any waveform into an antenna.

Is the output from that antenna a variable waveform photon, or is it multiple photons of different wavelengths being produced at once.

Or is it pretty much semantics? Where a variable waveform is just one waveform, but it can be described as multiple photons of different wavelengths, as per it's Fourier transform?

Apologies if I'm being dim.

It's more likely the military were interested in the tech so invested in checking it out.

If anyone is interested, gravity on the IIS is still 88.33% of earth's gravity. The IIS orbits around 408KM from sea level.

Here is a PowerShell script I wrote that will calculate earth's gravity at any given altitude (if you have windows, you can open it and copy&paste it in):

function Get-GravityAtAltitude
{
	[CmdletBinding()]
	Param
	(
		[double]$AltitudeKm,
		[switch]$ReturnStats
	)
	BEGIN
	{
		$EarthParams = @{
			MeanRadius = 6371.009 # KM
			SeaLevelGravity = 9.80665 # m/s^2
		}
	}
	PROCESS
	{
		$AltLevelGravity = $EarthParams['SeaLevelGravity'] * [Math]::Pow($EarthParams['MeanRadius'] / ($EarthParams['MeanRadius'] + $AltitudeKm), 2)
		if($ReturnStats.IsPresent)
		{
			$EarthParams.Add('Altitude', $AltitudeKm)
			$EarthParams.Add('AltLevelGravity', $AltLevelGravity)
			$EarthParams.Add('GsAtGravity', ($AltLevelGravity / $EarthParams['SeaLevelGravity']).ToString('.00%'))
			return [PsCustomObject]$EarthParams
		}
		else
		{
			return $AltLevelGravity
		}
	}
	END {}
}
Get-GravityAtAltitude -ReturnStats -AltitudeKm 408
