Quite extraordinary!! The last indoor I went to was in the 80s, in the big hangar at Cardington - a rather different offering! IIRC we had the first demo (for the RAFMAA) of an R/C indoor model - balsa and microfilm and rudder only. How times have changed!

Most amusing? - the 'witch', of course. Most eye-watering? - as an ex-helo man, that demented green 'thing' at the end of the clip!!

Some mind-boggling aerodynamics going on there - excessive electric power, of course, but the low speed stuff and controllability of the Antonov, ATR , Horton twin jet and the Viggen etc.would make some very interesting Perf plots!

Thank you Jason

Thank you Bazyle - that's what I assumed originally ... except that there is NO drawbar! Also, the lack of a 'proper' centre hole at the tool end means it can't apply pressure from there. It is a fairly complex item to manufacture with the internal rod securing the cutter using the knurled portion. All very puzzling!

Been trying to find info on the following 'milling cutter' (??) , without success. The cutter bit is held in position by a central plunger tighhtened by the knurled portion. It will only fit to cut TOWARDS the taper mount. There is a slot in the knurled portion to allow a pin to be drifted out to split the shaft. The taper is friction fit only, so cannot provide cutting pressure for the blade. there is a hole at the cutter end but not suitable for a centre. Approximately halfway between the knurled portion and the cutter there is a groove which is fitted with a spring ring. All in all, a total mystery! suggestions would be very welcome!!

Final gloss finish using Jeweller's rouge, perhaps? or, for cheapskates like me , toothpaste. Won't do for anything other than the very fine stage. Use to use it for watch glasses.

Trevor - presumably yours, like mine, are only suitable for 4 flute taps?

Having just broken an 8mm tap (best quality Chinese black chocolate!), this thread offered various 'escape' options. However, from the dim recesses of my remaining brain cell, I recalled a couple of oddments from 40 or so years back - see pic below.

The smaller of the two was adjusted to fit and ... Bingo! . It unscrewed easy-peasy!

I cannot recall having seen these mentioned previously nor seen them advertised. Anyone else own or use one?

Definitely one for the Tea Room!

I have used telescopic magnetic pick-ups ever since I started to mess about with metal. They are essential nowadays to cope with back problems. A rummage around Lidls yesterday found a batch of various mag tools and I grabbed a couple of combined pick-up and mirror packs. Broke open one of the packs when I got home and out fell an instruction leaflet!!! An instruction leaflet ... for a mag pickup?? Elfin Safety beyond ridiculous!! Just to confirm that H&S WERE over the top, I read the leaflet. ... Well, well, welll! Drawings AND instructions? Fitting new batteries ...? batteries? for magnets? Oh, wait a minute - that mag head actually has an LED fitted and 3 button cells to operate it! I HAD NO IDEA!!! Must be some new bright idea. Went out to the workshop and looked at my oldest similar one ... That was similarly fitted but having been in use for 6 or 7 years, the LED was well past its prime! It's been obvious for some time that I'm very good at 'Senior Moments' but this is Gold Medal standard!!

I realise that nobody else on the Forum would be so daft, but for anyone yet to use this tool, please note the extra facility!

More tablets, please, Nurse!

I know there are members who are into this sort of thing - (definitely NOT my bag! ) so, maybe of interest ... except for the price!!!

Thank you Emgee - sounds good.

Mike - it's reassuring that others have the problem! Scissors and card to the fore!

I am hoping to make a brass profile of an aircraft to be hardwood mounted. The dimensions will be approximately 7" x 2 .5". I am totally lacking ANY art/proportional skills and would appreciate suggestions as to best size/ proportion for the plinth. I would also like to incorporate a bras plaque on the plinth with relevant details.

TIA

It's the sharp division between 'old style' common courtesy and today's 'entitlement' culture'. Time was, "Please" and "Thank you" were standard currency, imposed in childhood and remained as adults. These pleasantries are now dismissed as unnecessary. I recently 'phoned the Council to thank one of their staff for having arranged a replacement 'wheelie bin' at short notice. The lady was absolutely amazed -" We NEVER get thanked by the Public". Such a sad commentary on Society!

Closer to home and the OP's well-founded comments, it woukd be nice if one could expect conclusive responses from forum members re. Sales and Wants - not at all universal, unfortunately!

Thank you all again.

From all the advice given, I'm concerned about the compressiblity of the cardboard I had intended to use. As I said, it's just a standard piece of a cardboard box and doesn't have the less compressible qualities of e.g. gasket material - maybe I'm over-worrying!

Bill

John and Old Mart - thank you. Both your suggestions are much less 'spongy than the card I have - no writing tablet and no cereal packet . I have a nagging feeling that what I have produced is not ideal! I shall have to search further.

I have a Tiplap grinder with two original Boremaster wheels. They aren't really suitable for general grinding, so I am fitting a carborundum cup wheel . I have made a new mounting adaptor but I am unsure about the type of 'washer' to fit on either side. I have cut our a couple from the cardboard of a tool package. Is this appropriate or should they be made from something less 'agricultural?

TIA

Thank you, everyone for your help and information. I have to admit a great deal was above my "red is positive, black is negative" level of knowledge - got totally floored by NDIY's mention of 3.7 and 4.2. Am I to understand that I'm dealing with made up series connected packs to provide the 12v? That would entail a REAL stripdown of the cells to do anything remedial, so the bin is looking likely!

Bill

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.

rgds

Bill

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!!

Bill

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!

Thanks Bill - unfortunately, it's Li-on.

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!
