Hello Raphael, I note Dave Davies 8 say he bought a capacitor and start relay. Has your compressor start relay got 3 pins on it similar to a fridge start relay, if so check it before buying a new capacitor, as you have the symptoms of a faulty relay. You mentioned the hum and then turn off, which I think the overload is switching things off ,because the start winding is not being energised.due to a faulty relay. Usually the capacitance value is printed on the cap can.John

Good comment John, I must admit when I was on the fridge tools it was standard practice to replace the complete starter kit, relays, capacitors etc, when one item had failed.

It wasn't worth the cost risk to skimp on the starter kit compared with blowing the compressor.

Thanks Simon, great help. I hope this is an easy fix as I really valued this old compressor. Jus another follow up question, do I need a motor start or motor run capacitor? Is the 450 volts to high for the 270 that I have? I appreciate your explanation, I just don't want to blow things up or fry the motor.

If you have motor start capacitor there should be a resistor fitted across it. If not then it is probably a motor run capacitor so make sure that you specify it as a 'motor run' item.

Plasma, one use in clock making that I can think of would be knurled clock case feet but seems kind of expensive for that.

Perhaps machine a Delrin piston first to see how it fits before the final metal version.

Seeing this thread content may I ask if it is okay to post links from Facebook?

That's up to Neil really but I would suggest people resist the temptation. There are half a dozen lathes, plus mills and so on newly listed every single day so we would be inundated and just turn into a repeater function for adverts. Not really what the forum is for.

Fair comment, thanks.

Of late there have been a few lathes and mills for sale in my area, Newton Abbot / Torquay, which may have been of interest to some.

Thanks, Brian

Thread: Tube Notching

AJ 1, very many years ago I worked for a firm that made tubular steel trolleys and the tubes were notched on a machine providing a similar method to the one that you are proposing.

If memory serves, it had a rotating cutter like a milling tool but mounted horizontally The tube was clamped into a movable vise and pushed onto the cutter.

Maybe make a sliding plug to go inside your tube so that a spare(?) drill chuck could be used to hold the non cutting end of the tube and improve your grip.

Seems fine to me using Chrome on a tablet.

Have you tried clearing your computer cache? Sometimes helps.

Thread: Overload trip
08/02/2019 19:41:55

Right, 8amps and 230vac would be a suitable size for a regular motor overload device however a temperature sensing motor protection thermistor might be a better solution.

This link is to an American source but gives a good insight into the device.

The thread subtitle declares:

"8 watt 250 volt AC motor / gearbox."


Thank you MichaelG, I hadn't read or adsorbed that bit of the title, I'll sit in the corner quietly for a bit.

May I ask what the voltage of the motor is and is it ac or dc?

Thread: Very soft stretchy rubber grommets, where from?

I think I know the type of thing you are looking for but for the life of me I can't name them.

In the meantime is there anything suitable from this grommet company....

Why not use what is specified, worst price I've seen was £4 a metre.
