Thread: lead acid battery charging, will this work
04/11/2020 21:23:27

Thank you, Robert and Peter - The grinder is a Lidl branded 20v item and dismantling it (VERY tricky) shows a compact installation with a thin oblong completely sealed unit between the battery and the on/off switch. This, I assume, contains the monitor and balance functions and is (for all practical purposes) internally inaccessable. The monitor item I was considering was somewhat simpler than your item, Peter, having built-in digital voltage read-outs and (I assumed) intended to be wired directly between the battery and on/off switch to give real-time battery voltage state. The thought was to monitor this value and stop using the grinder when the indication was at an appropriate (rechargeable) level. The supplied charger has all the necessary protection circuits and is fully serviceable, as is the battery pack (at the moment). There are probably difficulties which I haven't appreciated due to lack of knowledge - hence the call for advice.

My Bambi is most definitely quieter than anything else I have heard in action.

Thread: lead acid battery charging, will this work
04/11/2020 11:48:35

Sort of on-topic - I have a non-working cordless angle-grinder which failed to switch on after 2 use cycles. The battery is fully charged, and, therefore, the assumption is that the battery protection circuit has failed.The charger works fine and the motor and output drive are undamaged and almost new. I cannot obtain a replacement protection module and don't wish to throw away an otherwise useful tool. Question - Would interposing a generic battery monitoring device between the battery and motor be sufficient protection to enable continued use or are there other problems to be considered? The item being considered is available widely at moderate (£12-15) cost. Battery working voltage is 20v

I don't have the technical knowledge or skill to manufacture anything suitable, but could, probably, manage the soldering involved.

On-topic -ish, a member's want ad has been posted with the reply function disabled due to lack of "public profile". I can't see any work-around for that.

It took me 12 month + but very rewarding and for myfirst project I am relly pleased with it.

I keep reading that the hobby is declining - I wonder why!

GW1 - Your wife may not appreciate your efforts but, I do! As de facto 'cook' for self and partner, my constantly less effective grip makes 'normal' round centrally placed knobs increasingly difficult to grasp. Your 'repair' as a properly incorporated design would make life much easier!

Patent Office, anyone?

Thread: Parkside (Lidl) Cordless Angle Grinder
27/10/2020 14:49:44

Just to update my earlier input re. the Lidl cordless angle grinder.

I did as suggested by inf and RMA above. Quite exceptional! - almost nil waiting to get through, a quick, to-the-point Q&A and an assurance that I would be fully reimbursed as they couldn't replace. Passed them my bank details, nothing for 8 days, then message to say full repayment made to my account. The machine may be crap, but that sort of customer service is excellent and I passed on my compliments.

Since ther was no request for the item's return, I am exploring the possibilities of restoring some of its function and have a separate thread seeking info.

Thanks to all and well done Lidls!

Thread: Cordless tool electronics
27/10/2020 12:07:42

Thank you to all responders - I understand the potential problems.

The angle grinder has been used on two occasions only and it just stopped with no warning and no smoke. Opening it up shows no signs of internal component distress, hence the query. I suspect that the electronic, as distinct from the electric, bits are the problem, but I wouldn't know where to start in repairing such. Are these obtainable as 'off-the-shelf' items or are they 'home brew'? All the mechanicals, plus charger and battery are fine, so, any suggestions other than the bin?

It seems that most (all?) li-on battery powered tools incorporate some sort of electronic interface between the battery and the motor. They seem to be a potential (and actual) source of trouble. The only information I have found demonstrates by-passing this interface and just making a 'normal' battery-switch-motor circuit - which worked. This being so, what is the purpose, and importance, of this extra bit of circuitry?

I am aware that in the aviation world these batteries are viewed with suspicion and caution. Should we be similarly concerned?

PS I am considering 'repairing' a cordless angle-grinder using this method.

Thread: More on Austin cars
16/10/2020 10:19:24

My first car was a pre- WW2 Austin 8, bought in '56 in Aden. In retrospect (and unsurprisingly), it was lethal. The leaf springs were loose, the steering had over 3/4 of a turn play and the brakes were totally ineffective. An optimistic visit to a local 'garage mechanic' in Crater gave no improvement but resulted in one of the rear wheels detaching on the way back. I have no idea what I did with the thing when I left at 'Tourex' - and probably just heaved a sigh of relief!

Thread: Looking for a very small lathe.
06/10/2020 17:42:31

I have Cowells, Pultras, Taig, Unimats 3 and SL and two watchmakers lathes. In terms of useability, the Cowells heads the list, followed by the Unimat 3. If I were in your position, with no financial limit, I'd go for the Cowells (new spindle 14 x 1) ; with limited, but reasonably deep pockets, I'd look at the Sherline (local clockmaker has the extended bed version and swears by it).

Thread: Martin Cleeve Swing Clear Retracting Toolholder
04/10/2020 10:13:47

I have a pair of swing-up holders (one in use) purchased secondhand, and a bit 'agricultural'. Very handy for allowing easy dimension checks and resetting centre height for different tool sizes. John 'bog-standard' made an example of the self-retracting holder on another forum and seemed very enthusiastic.

"playing in the shed" - ??? Would that I could play just a tenth as well as those pics show!sad

The wife of a distant friend was similarly dismissive of his hobby of model soldiers/battle re-enactment etc., and would refer to him as " out in the shed, playing with his privates again !"

Thread: Machinery hire?
02/10/2020 10:48:13

Just an update.

More in desperation than optimism, I phoned the NNDC yesterday morning. The usual multitude of options brought me, eventually, to a young man who had the remarkable talent to interface with potentially irate callers. He could not have been more conciliatory or helpful and assured me that he would process my query immediately and ensure that I got a response. In the middle of lunch, doorbell rings and a young lady said she was from the Council and was checking on our problem. She assured us we had been added to a list of affected properties and would definitely have the sand cleared in due course!

The exclamation mark of surprise is based on the previous reaction of the same Council when our house was destroyed in the 2013 storm. Totally 'chalk and cheese'! My innate cynicism says 'wait and see', but if things are as indicated I shall ensure that a letter of appreciation is sent. Maybe, ..... just maybe !

Huge thank you to all for those most useful replies. Interestingly, our house features in Ady1's link video (the view showing the sandscaping scheme display - that's our wall).

The various machines available are a 'boys' toys' Xmas list! ... however, the wise counsels will prevailsad

Insurers first, (not hopeful), Council next (cash-strapped, so similar) and then to find a reliable 'man-who-can'. Our treasured long-term 'go-to' man isn't contactable so it will be search and hope.

Thank you all again, it has given much food for thought!

We are just (I hope!) coming to the end of a particulary vicious 2 day gale. It has caused a somewhat difficult problem, in picking up, and dumping vast quantities of sand from the recently installed 'sandscaping' coastal protection. Drive, garden, patio, all buried under tons (literally) of the stuff. Years ago I would have set to with shovel and barrow but at 85, it's not really an option. I am not up to speed on what might be available as personal hire machinery which might suit the purpose. Can any members better informed suggest what might be suitable - one, limited mobility operator 3' width limit for gate access?

TIA

Thread: Covid causing mental health issues.
26/09/2020 12:22:16

Apart from engendering respect for other creatures or life forms, pets, of whatever type are a huge benefit. As a 'cat person' I find their presence essential and our two are treated similarly to Samsaranda's. Winston Churchill's dictum that " Dogs look up to you, cats look down on you and pigs is (sic) equal" rings true! An Australian bumper sticker, apparently, proclaiming that "Dogs have owners, cats have staff" equally so. Interactions with dogs are pretty straightforward; with cats, much less so but more rewarding when they work. Yesterday's news of the deeds of a giant rat PDSA 'hero' was quite uplifting!
