Thread: Parting tools and inserts
23/02/2022 10:38:10

I found insert parting tools rather expensive to use. I switched back to HSS but chose the T shape blades with chip breaker which work extremely well.

For Five quid I wouldn’t bother.

Go back to the vendor of the lathe and ask them to fix it or provide details of the EMC qualification.

Robert G8RPI.

The lathe is over ten years old and the issue has only surfaced since the video camera was replaced.

The lathe and associated inverter are as supplied by the retailer. The inverter is already in a metal box mounted at the back of the lathe.

The inverter is possibly a Delta S1 (shown in the manual) but I’ve not actually seen it.

I’ve just seen this in the lathe manual.

“If a filter is required to reduce EMI install it as close as possible to the AC drive. EMI can also be reduced by lowering the carrier frequency. When using a GFC (Ground Fault Circuit Interrupter), select a current sensor with sensitivity of 200 mA, and not less than 0.1 second detection time to avoid nuisance tripping.”

This seems to be saying: “We know our inverter causes EMI but we’ve decided not to deal with the issue”. laugh

Look at Clough42 on YouTube 3 years ago on this very subject

Tony

That’s very helpful Tony, thank you. I will pass on the link.

Apparently the lathe and camera remain in fairly close proximity. The problem is somewhat reduced but not eliminated if the two items are physically plugged as far away as possible from each other.

Be aware that washing machines will block a drain with a chalk like substance which sets quite hard, I had to jab it quite heavily to dislodge it.

Thats the "inert filler" from the washing powder, it is usually chalk! Change to a liquid laundry detergent!

We’ve been using laundry liquid for very many years. I read a long time ago about the problems with soap powders.

Throw a bit of non-caustic biological drain cleaner down the sink once a week it will take care of it. The bacteria in it eats the fat before it forms fatbergs. We used to do that in the hospital kitchen drains where I once worked in maintenance because it meant we never had the unpleasant task of delving into the grease traps to clean them out.

Have you got a link please for something suitable?

Thanks for all the info folks, much appreciated. wink

Thread: Inverter interference
21/02/2022 22:43:34

A friend of mine is having some difficulty with the inverter on a lathe causing occasional signal drop out between a video camera and projector. It’s assumed this is through the mains wiring. Is there some kind of filtering device that could be placed between the mains socket and the camera to prevent this? TIA.

Thread: Blocked Drain
21/02/2022 13:43:30

Ok, jobs done. The trap is back in place. I bought a screw connector and cut the pipe. I can now easily remove the grate and the trap. Hopefully though it won’t need doing again for another ten years!

Hello Vic,

I have the same fitting at my house. I think the sleeve forms the water trap to prevent foul smells to atmosphere.

Regards,

Rob

Yes, that was my first thought.

21/02/2022 10:28:38

I’ve just managed to unblock a drain outside our kitchen. It had quite a few stones and some lumps of solidified fat in it. The blockage seems to have been trapped between a black plastic funnel shaped sleeve and the drain itself. Anyone know the purpose of the sleeve? I need to modify the pipe that feeds the drain but until then it’s working nicely without the sleeve. I will refit it once I’ve done the pipe. Just wondered what’s it’s for as the drain flows quicker without it.

The Sleeve.

Thread: Smart meter

Seems the latest generation of 'Smart@ meters may have to go to a third generation as, around Fylingdales, they are accused of affecting the nuclear warning systems.

Regards Ian.

I get the impression that they haven’t thought this through properly in terms of functionality etc. especially if they want to manage supply and return from things like EV’s etc?

I’ve just seen these and thought they looked quite handy. Are there any modern versions of these available at modest cost? I’m really not interested in the large plastic visor type.

It has lot of little features that wouldn't help with buttons?!

Thanks!

I would suggest that it is something ‘made from’ a button-stick

… yes, probably a DIY template for mouldings.

MichaelG.

Yes I agree.

As Thor says why do you need to use 16mm tools on a hobby lathe, I have a 280 x 700 and the largest I tend to use 10mm.

Maybe he wants to use 16mm tools? The advice very often touted about machine tools is to buy the biggest you can as they are more solid. Same with tool bits. If you can afford the bigger ones no reason not to use them. I have a 8 1/2” x 14” lathe and generally use 12mm tool holders but I also use 16mm ones cut down to 14mm to suit my tool post. For some of the triangular inserts I use (very economical as you get 6 tips) I don’t think you can even buy a tool holder for them smaller than 16mm. Small tools are fine for many jobs and can get in tighter spaces but no reason not to use the larger ones either. A quick look on the auction site indicates you can still get them for about a tenner.

OK thanks all. I've got some pickled onions, so might mix it 50/50 with the Sarson's stuff and try again on an old drill chuck I found.

I don't quite understand the appeal of home concoctions when commercial products are available.

The only home method I've been impressed with is br's "I get good clean results with a bucket of water, washing soda and a 12v battery charger."

Dave

And at £1.75 for a 1.5kg bag of washing soda, ,delivered, it is as cheap as chips, as one well known presenter used to say.

bill

Yes me too. It’s so easy and unlike even mild acids doesn’t etch the surface. Washing Soda is 80p a Kilo in Sainsburys.

Thread: New highway code rule.

We will have to wait and see but the last time I looked at an article on the subject they claimed it would reduce accidents by 95%. No surprise really when you see the state of some driving on UK roads. I suspect the ultimate goal is or will be to take private transport out of public hands completely. Having a cheap reliable on demand service will certainly not appeal to most motorists now but for those that can’t drive or afford to buy a car it will be a godsend. I never forget waiting nearly an hour in the freezing weather for a bus that was supposed to be every 14 minutes.

Thread: Temperature control when grinding HSS tool-blanks?

If micro cracks are indeed a consequence of dunking your tool laugh when it’s too hot, what are the practical after effects. Tool breakage, poor finish etc or something else?
