Thread: Battery charger problem
03/10/2019 17:38:33

Andrew and Neil, thank you.

Andrew - you have picked up on the major difficulty - there are three terminals. I see between 9 and 10v between two of them and zilch with the 3rd. A Youtube battery strip-down on a similar pack showed a small circuit board which puzzled the wiggly amps expert . He finally decided that it was a low voltage sensor to prevent asymmetric charging, since there was (he said) no balancing circuitry.dont know

Thank you all. Some interesting information again and the 'culprit', apart from my stupidity, was the wrong charger (10.3V instead of 12). The main prob;em now is the shape of the pack but I have found and ordered a similar looking replacement.

Duncan - that had occurred to me but then I remembered my 'soldering skills'!

Peak4 - Hmm, I have the kit, as ever, expertise is wanting!! sad

Thank you again for your replies.

John Olsen - that's the information I was after.

XD 351 - that (polarity swap) would seem to fit the bill. Unfortunately, the battery pack is one of the 'triangular' type and appears to be available only from the 'hen's tooth' factory! sad

Mick B1 - Sorry, don't know about the serrations - would guess cast-in; doesn't retain the kernel, it falls into the tray. PGK x2 - the actual thread is 'buttress(y) so presumably Acme or square.) Source, as with so much of my bits and pieces was a charity shop!

Thread: Battery charger problem
02/10/2019 18:09:53

I have a Parkside (Lidl) 12v rechargeable drill/screwdriver, the type with a 'triangular' battery pack. The charger 'went walkabout' for a few days and, needing to recharge, I plugged it into a charger for a Parkside vibro saw ... not noticing it was a 10v machine. The charge indicator went straight to green and I, foolishly, left it like that for several hours. It remained green and when I removed it and tried to operate, it's dead!. I have since found the correct charger and tried again but it goes straight to green, doesn't charge and the battery, obviously remains flat.

Apart from requesting a brain transplant, can anyone suggest a remedy , please?

Thread: Aero Fuel
29/09/2019 18:36:35

In the mid 60s I was operating for a while in Burma (now Myanmar). We had a hire car provided - an old Humber Hawk (the local economy couldn't afford new car imports) . The fuel available was 78% 'Pool' petrol. Accelerating DOWNhill from the hotel produced severe 'pinking'. Progress CAN be wonderful!

Thread: Unusual GPO hammer?
28/09/2019 23:42:09

Aaaah! - Government nomenclature! Auntie Betty's Flying Circus was similar plus a whole vast array of paper vouchers, inckuding Issue, Exchange and Return. Memory (VERY fallible nowadays) suggests Conversion vouchers - MOST useful for making good inventories which had become depleted. Oft repeated was the old Storeman's ability to 'Convert' HangErs Clothes to HangArs Aircraft! Even so, it was well-founded wisdom to be good mates with the Stores chaps! One such genius, at Tern Hill somehow managed to 'vanish' 10 Tables, long ,library plus one Simulator, Helicopter, Training which I had signed for but had never set eyes on!!! Made Paul Daniels look positively pedestrian!

Mick B1 - assuming Carol is your SWMBO, I can well believe that she appreciates both the cormorant and your previous - super work! - clever (visually and proportionally) mounting. +1 for both.

Much used in model aircraft , for push-rod ends and similar. Almost anything requiring thin high strength - lantern pinions for clocks maybe? Very useful stuff, particularly as you appear to have a number of different gauges.

Thread: Brooks Stent Grinder Plans
05/09/2019 17:37:34

I have both a Stent (near complete*) and a Worden (most bits plus dedicated motor) surplus to requirements. Both are in need of cleaning /derusting and I have neither time nor inclination.

* probably complete but would need to gather all the bits, as it has been dismantled!

Thread: Bandsaw blades
30/08/2019 21:13:47

Just an update on my bandsaw problem (or one of them, at least!) I ordered a replacement for the Naerok from Trucut (as recommended). Slight delivery delay but now received and fitted and working well (fingers crossed!) Its other problem, the breakup of the 'tyres' was solved by utilising an old leather belt, slitting it lengthwise to correct width and glueing it in place with inch length scarf ing at the join. Used one of the modern 'glue everything' clear variety with cyano at the joins. There are SOME advantages to getting old and FAT!!

Now to deal with the Axminster - tyre or no tyre??

Not a good weekend for mechanical saws!! So far, one Naerok blade break, one Hegner similar, one Axminster blade came off the wheels - fingers crossed, the trusty old Kennedy carries on regardless. The query is re. the Axminster - there appears to be a 'tyre' only on the drive wheel - is this correct? also, that 'tyre' is spongy, very loose fitting and appears to have absorbed cutting fluid (WD40 for ali). Any comments, please, from members who are familiar with the Axminster or similar 4.5" saws?

TIA

pgk - the "charcoal for poor folk" persisted into the 40s at least, although it was given as soot (from the common family range). Applied by finger, not brush and, supposedly had a natural whitening effect. War-time restrictions probably led to it being encouraged.

Thread: Myford ML7 tailstock bore, and threading the barrel to fit a chuck
23/08/2019 16:24:35

Only just come across this thread but it leaves me puzzled (not uncommon, these days!) . I must be misunderstanding the problem, 'cos I would have used my 2MT insert with an ML7 nose thread in the tailstock and then screwed on the 4 jaw. Obviously missed something but can't see what. This insert has been most useful over the years, allowing chucks at nose and tail 3s, 4s or one of each. If nothing else, it makes centring stock in the 4jaw easy-peasy. What am I missing/misreading, please?

Thread: Bandsaw blades
22/08/2019 11:01:37

Thanks again for all the useful advice and, particularly, a PM from Ian W setting out the options. I think that I shall go for a primarily wood use replacement.

Gary W - yes, the Clarke model is a 'dead ringer'.

21/08/2019 18:04:15

Robin, Brian and Chris, many thanks. I think the made to order replacement is the way to go. Just a further query - what should one specify for an all-round blade (Bi-metal, tpi etc?) or should one get separate metal and wood use blades?

Thanks again

Thread: Are there any left?
21/08/2019 17:55:33

Started S&R helo flying in '64.The nature of the work required that we used throat mics rather than the conventional type. The RAF, as usual, failed to organise a supply so, on joining we were told to go to a particular surplus shop in Soho to buy an ex Army tank crew throat mic. - 7 shillings and sixpence, refundable on production of the receipt!! This item was then given to the Safety Equipment section who removed the connector and attached an aircraft compatible one. From memory, it was about 18 months before we received the custom designed replacements.

"Yes, dear, I was in Soho on Government orders" embarrassed
