Bob, you're looking down the wrong end of the telescope me old china!

We're living in a target rich environment and it's only getting better, whilst we are getting older, slower and considerably more cantankerous (had to check that with the auto spell!) we are the last of the line and as such are a diminishing resource.

Remember the late '80's when computer designers and programmers were on the scrap heap, burnt out at 30? It's not going to happen to us, witness the blokes that fixed Glorts starter.

We can still survive (and prosper, more to the point) with technology the Victorians would understand, can't see any reason to get the blues, adjust your attitude forthwith!!

Sadly BruceM as things become more disposable there is no requirement for spare parts or the people with the skills and knowledge to fit them. We will be consigned to history and "progress" will continue unabated until the all the world is owned and controlled by a few greedy individuals who have no regard for their fellow humans or the planet.

I have very grave concerns for future generations, how are they going to earn a living when everything is made by robots in totally automated factories? Where are they going to live and what are they going to eat when everything is owned by government or big corporations? How are they going to fight back when the only skill they have is using a smart phone, via a communication system owned and controlled by the same greedy corporations and government?

Getting old is beginning to look like a blessing, at least I have had an interesting and fulfilling life, doubt I could survive in the future, struggling with the present, I guess that`s why we are all taking anti-depressants.

I was helping a disabled lady with her 1999 Toyota Rav4 last weekend.  Needs a new shift control solenoid that keeps you from moving the shifter from park unless the brake is on. No aftermarket parts available and the Toyota price is $400 !  Since it only sticks in very cold weather I removed the cap and showed her the manual override button.  If it totally fails I'll just remove the damn thing. 

Kubota tractor prices are also bordering on criminal.  I've to make a fair number of new parts and new bushings, and do some plastic repairs. 

We live in the disposable era.

Yes, Franklin is very proud of their PV direct inverters, and the price isn't cheap in the US either.  It made me feel good about my homebrew 5 step sine inverter development.

+1 MikeNash's comment on pumps. Any pump you buy should have a head vs flow rate performance chart so you know just what to expect.  If a pump is sold as 3 meters of head, and 12 LPM flow rate, the former means zero flow at that 3 meters, and the latter means 12 LPM at zero head or lift.  You will be very disappointed if you think that meant 12 LPM at 3 M. There should be no surprise if you understand the usual marketing approach used for pumps, and get the actual performance chart so you can find the flow rate at your intended head or pressure.  If they don't have a flow- head performance chart, pass on the pump.

The problem with automatic watering systems is that the batteries must be in an outside ventilated enclosure or you could have a Brown's gas explosion risk on your hands.  If you're in a cold winter climate, that doesn't work well with water filled tubing.

Any time you have high battery water use in lead acid batteries, you must be seriously overcharging. I have a hard time believing Mike's NIFE battery water use is also not caused by gross overcharging...either excessive current or voltage, but I must assume he has confirmed this as normal from other NIFE users.  I'd be monitoring gas bubbling, current and voltage throughout the charge cycle to try and figure out what's going on. If I had no other way of doing it, putting some cloth on the PV to reduce charging current would be useful to see if there's a level below which they will charge without gassing so darn much.  Clamp on DC amp meters are not that expensive now and most are adequate.

Ebay has it`s uses, I need a new 25 micro farad capacitor for a mate`s generator. Local electrical suppliers want $30 and I have to make a 100 km round trip to go and get it. Identical item, from China, $4 including delivery.

Which one would you chose?

Not 3 hours later and they ring me, come and get it.
$90.  Working like a new one.

Now just to put it all back together.

Cam belt I had another look at . it's not cracked and can still see the writing on the thing so I think I'll put it back and then get the belt and do it in winter.
Some year.

I'll start looking the machines up!  :laugh:

Hey Glort, the beauty of CNC is that you don`t have to be a precision engineer or computer programmer to operate it. The designs are emailed to you by an architect, designed or engineer you upload that spec to the CNC cutter and it does all the work. The only thing you need to do is put the correct material onto the cutting machine and tell the client to come and pick it up when it`s done. Most CNC cutters also have the ability to work out the most economical way of cutting sheet material thus reducing cost and scrap.

The brain power of some of the guys operating this sort of equipment is nothing to write home about, I suspect that after the first few weeks you would be bored stupid by it.

Now who is a mind reader?

That had actually occurred Bob!
Trouble is the word precision is never applied to me or anything I do, ever.  i don't think I could get my head around learning it all now either.

Whatever I do has to be simple for me to get my peanut brain around it.

I once bought a marine Bilge pump. took it out the box and pumped some water and was disappointing with the flow. Measured it and it was about 1/3rd the stated rating. Got on teh web to look them up and found a very recent article by a boating mag on Bilge pumps. Opened it up and the very first line said the first thing to know about all bilge pumps is the numbers have nothing to do with performance.
The ratings on those  really are nothing but fiction. Same article also had a chart on how much water a hole of different sizes in a boat would let in. Surprising. Suffice to say if you think a bilge pump would help you from sinking if you did punch a hole, you will want  several of the biggest pumps they make to have a hope.

I had silly idea of doing a shallow bore when I got here. Going down 9ft and still only seeing dust put that idea into perspective.
I had bought a bore pump with 150M head or something and decided to just use it in one of my tanks.  The thing is like a fire hose! Better than my petrol pump in fact.  Only use it at about 1M head but this thing has some pressure.
On a 3/4 Hose it really lays down some water fast. Love to get some 1" hose, the pump has a 1.5 Outlet so would carry it easily.
One of the best pumps I have come across. Been looking for another for the front tank.

Don't have to refil the thing or buy the fuel. More power this time of year than I know what to do with.
