Thread: Aero Fuel
29/09/2019 00:15:20

Probably to allow the engine to run on whatever basic petrol was available in the area/country they were operating in.

The fuel being delivered by tankers or jerry cans could have been used by an assortment of engines, jeeps, tanks, lorries as well as aircraft.

Remember that these compressors are refrigerant compressors that are supposed to be cooled by the flow of refrigerant through them.

You should find somewhere in the instructions of your unit the recommended duty cycle. This should be designed to not overheat the motor by running too long and also not starting the motor more than a set number of times per hour.

dont know What exactly do you mean by these compressors, Brian ?

Sorry, should have added "hermetic" type.

Could be the compressor starter or capacitors at fault.

What size tube are you looking for and material type?

There is a good range of 'plastic' reinforced tubing available.

Thread: Rip-Off? Don't judge by web domains.

I like the ebay price offer, buy two and get 5% off the second one. Good deal.

Thread: Any interesting lathe projects for beginners?

There's always a chess set.

A lot of extension leads have trip switches attached to the socket outlet, check the lead on something else.

A wire tester will not tell you if you have a circuit, the neutral may be broken.

Thread: Scissors
13/09/2019 14:44:22

Your button hole scissors have a small rachet stop for setting the cut length of the hole. Other models used a screw through one arm to set the cut.

Thread: EGAMASTER 'MasterGrip' Pipe-Wrench or clones

I see Sulco NZ have one for about 210$ plus tax, not one you'd favour I think.

Narrowboat on the UK canals.

Slow and quiet.

Thread: Water pump shaft clearance?
14/08/2019 23:52:26

Might be a silly question but is the pump motor section full of water otherwise a dry running pump will be noisy.

Thread: Grid Frequency [mains electricity]
13/08/2019 00:13:17

This subject was broached some time ago I believe.

One of the problems with maintaining a stable frequency is the inputs from renewable energy. The wind and solar input to the grid will upset the status quo so that the base power generating equipment has to back down to prevent a rise in frequency.

When the wind drops and the clouds cover the sun the drop in frequency means the base power has to come on line quickly to maintain the power levels. With insufficient standby generating equipment there is likely to be brown outs or cuts happening more often.

Thread: Bulking problem?
09/08/2019 21:28:21

Would drilling the diameter that you want through a length of good wood. Then cut the wood along the length so that you end up with two halves.

Heat the horn and then clamp it between the two wooden moulds.

I expect that you would need various sizes so that the horn diameter is reduced in stages.

Thread: Hieroglyphics on a Wehlen & Co clock face
09/08/2019 13:47:34

They look similar to printers typeface marks, if you look at some of those in the attached link they have the vertical line crossed with several horizontal ones.
