Sad news.

I know this is an American site but you can get remote controls for those actuators which could do away with a manual switch.

Download their pdf catalogue for more info. **LINK**

No connection with this product.

Thread: Bevel ?

You might say that a bevelled edge is found at the end of a wood chisel whilst you would chamfer the edge of a turned piece to remove the sharp edge.

The "Bevel edge" of wood chisels is along the back and does not refer to the primary and secondary bevels that form the cutting edge

I fully agree about bevel edged chisels which is why I said 'found at the end' to which you then confirm by talking about the primary and secondary bevels.

But if being pedantic then you have also confirmed the description of a bevel.

It seems that it can be an open ended answer depending on whether you use the words as a noun or an adjective.

Found a good description here  **LINK**

Adjust the leadscrew bracket at the right hand end to realign the thread and gearwheel.

I thought that they uncoupled the pistons at the cross head so that it freewheeled.

Concur with Joseph's advice, would add however - ensure that you get the correct voltage when buying the new capacitors.

Speedy recovery Steve. Time to start thinking about that seat to fit under the workbench now.

The wonders of the web - now we know the maker you can find it 0n youtube, amazing.

Thread: Help needed getting a Triac up and running
25/12/2017 15:06:00

Can't help with your main problem I'm afraid but in reply to item one.

Yes, falling voltage will cause an increase in amperage to compensate and that can/will damage compensation.

Thread: Risk assessments

Duly noted, thank you.

Thread: Central heating query

If you wire it so that your timeswitch supplies power to the thermostat then there won't be any power to it during the OFF periods.

Thread: Security

This section of the site does not need encryption, if you go to the subscription section then you will see the safety padlock.

So, yes it is encrypted where it needs to be.

Thread: Single phase to 3 phase motor conversion.

If it has a 90 frame motor fitted I would replace it with another 90 frame as it would be an exact physical size swap over.

Link here is from another forum regarding a French site, Google translate does the rest.

Thread: Lathe vibrations
16/12/2017 23:58:45

Just keep an eye on the motor temperature when running at reduced speeds, the 1.5hp one that is.

16/12/2017 22:32:35

Whilst appreciating the potential electrical hiccups is there any mileage in there being a problem with the bearings?

I know that you have checked the balance of the rotor and pulley but this was outside of the motor frame.

Are the bearings tight and square on the shaft?

Are they a good fit in the motor casing itself? Did the casing go back together in proper alignment?

Just clutching at straws here.

Thread: Titanium properties

Looking at images of the nickel titanium tools they appear to be cut on opposite sides rather like collets thereby allowing some extra flexibility.

Thread: New compressor required
11/12/2017 18:06:41

The silent compressors are generally hermetic refrigeration compressors.

The reason for the reduced duty cycle is that the motor does not have cooling refrigerant running through it only air.

In normal "fridge" usage the compressors often have a maximum start regime of six ( sometimes 10 ), starts per hour. When the motor starts there is an inrush of energy which generates heat in the windings, the motor then needs to run for a reasonable period the get rid of the heat. When running on air only the motor cooling is minimal.

Also, as an air compressor any oil carry over in the discharge pipework needs to be mechanically caught and returned to the compressor or at least the level monitored so that it can be topped up. In a fridge the oil circulates with the refrigerant and finds its own way back.

Most VFD manufacturers will confirm that changing the switching frequency upwards can reduce the perceived noise.

It is possible to overdo it so I would suggest that you read up on your particular make/model.
