The side view. J

Here are the pictures - rather big I think. J

Hi Gary

From R/S Components -

KEMET PZB300 Paper Capacitor, 275V ac, ±20%, 100nF, Through Hole
Stock no.:121-5449

It is a little too big to fit inside the motor so I added extra lengths of wire to take outside the motor cover. I will try to add a picture of what I have done.

The motor is running fine and back on the lathe.

Golly mate, we go to the supermarket here.

Thanks for the prompt response.

Having read the supporting technical sheets, I have found a capacitor. Super, thanks for that.

I had to strip apart the motor to get to the capacitor and found a rough bearing. So I will change the bearings as well. I rather dread putting it back together as small hands and some craftiness required to get the wires in the proper places.

I will try putting it back together to confirm the capacitor failed.

Old subject, but my little SL Unimat has, after all these years, stopped. The issue is that the 1A plug fuse is blowing. I have tested the safety capacitor resistance and that is nil between terminals.

Reading the messages about, the SillyOldDuffer thought that a replacement can still be found!

I am sitting here in front of this PC for some time and cannot find a 3 wire “safety capacitor” or “suppressor” in F-arnells or “RS” or all the other b/s on Google.

I am looking for an axial capacitor rated as 0.01uF 2x 2500pF - I cannot read the makers’ name as that is not legible.

Some help needed please.

Hi Peter,

I use pad and pencil with my calculator so I can always refer to it. Never used the fancy functions on the DRO system.

Hi Jonathan, welcome.

Hi Simon

Did you get the help you were looking for?

A good feeling then. Nice

The cabinets and drip tray are fairly flimsy. I put a thick piece of plyboard inside the top of the cabinets and bolted through. That has solved the floppiness.

I also had to add a piece of rubber (I used some inner tube) to seal off the bolt holes in the drip tray. Warco do not supply any seals saying that this was user solvable(?).

I haven't bolted the lathe down as my floor wasn't level. I used the bolt holes to level the lathe.

Oh dear, lots more practice - or use a brush

Hi Jerry

Some way to go then ;~}

Hi Peter

I recently bought a 1/4 x 40 syphon and banjo fitting for a steam pressure gauge -

If it works have a look here on page 38 of 60.

Fab.

I bet you didn't ask the indoor manager if she wanted it fixed. Most likely would have asked for a more efficient, more powerful, lighter and cordless.

I'm sure that Mr Grumpy bragging about his repair got a lot of muttering .

John

I am sure that felt good. Well done.

J

Good one ☝️

Looks a bit time expired to me.
