Thread: This trolley/cart could be useful
21/05/2022 19:15:06

Anthony, I have had the same B&D version that you have, bought ours many years ago and it has given sterling service, has carried 500 kilos at times and still going strong. You may think it is crap but I looked around for a potential replacement when it finally gives up but versions on the market now are crap in comparison, I think I will give ours a repaint and overhaul.

Thread: Oil can (again)
19/05/2022 22:01:46

Further to my post above the oil can that I ended up buying, and yes it was a cheapo, came from the website of the National Motorcycle Museum, it carries an advert for Castrol oil and is in the company green colour, it does dribble but nowhere near as much as others I have had in the past, it has a flexible spout so it easily reaches the push button oilers on my machines, I wouldn’t be tempted to replace it with an expensive one it does the job.

Oil by its very nature is made to penetrate incredibly small and tight clearances to function as a lubricant, you will never stop it finding its way out of threaded items such as oil cans or guns, all threads have some degree of clearance hence oil leaking out. I just use a cheapo oil can and wipe up the dribbles and store any containers with oil in them on drip trays. Like Dave’s mine also isn’t a clean sparkly workshop, it’s lived in, just put up with oil dribbles, you will never get rid of them. Dave W

Thread: Wyvern crankshaft question

I remember my Matchless G80 crankpin had thin nuts locking the outer ends of the crankpin. Dave W

Thread: Re-boring Grind Wheels
14/05/2022 19:00:34

Definitely moulded, you can see that if you look closely at the wheel before mounting it. Dave W

13/05/2022 09:48:31

Because of the serious consequences that can happen with a grinding wheel accident I wouldn’t tamper with a wheel, just buy new and as recommended go for quality product, your life is too precious to take risks with, grinding wheels when they explode can kill. Dave W

Thread: Gallium
07/05/2022 19:06:27

If it reacts with aluminium like mercury does then it will be deadly with aircraft. We had an aircraft where a stone jar of mercury was smashed in the freight bay and before long we could see daylight through the holes it made in the aircraft pressure skin. Dave W

Thread: Emergency Radio Format
03/05/2022 17:44:34

I find it incredible that our nuclear deterrent could rely on the broadcasting of BBC radio 4 with our sophisticated communications network that can broadcast underwater, as incredible as I find it, it fits with the quirky way our country operates in many areas. In respect of a nuclear attack, if you are out in the open, you may see the initial flash but will probably be vaporised before the sound of the explosion reaches you. We live in very dangerous times. Dave W

Thread: Galvanic Corrosion
03/05/2022 11:26:17

Aluminium and Stainless definitely don’t mix unless separated by a suitable inert compound, I have a Ring doorbell and the aluminium body is held together with stainless screws, and you guessed it, it’s corroding because a doorbell unit is outside and obviously gets wet. This is the second Ring doorbell I have had, first one failed when water penetrated and did for the electrics, and would you believe it was out of guarantee period. Do manufacturers deliberately use dissimilar materials to promote premature failure and guarantee future sales or are they just blissfully unaware of the characteristics of the materials chosen to construct their products and the consequences of their choices. As an ex aircraft engineer I can vouch for the effectiveness of such products as Duralac etc. they do a very effective job of preventing dissimilar corrosion. Dave W

Thread: How I am wasting time
03/05/2022 10:51:16

Went on a visit to Port Talbot Steelworks in Wales in the early 60’s, it was mind blowing when we were in the area where they were discharging the steel, molten metal and sparks flying everywhere and the noise was horrendous. Certainly glad that I didn’t have to work there, great respect for those that did. Dave W

Thread: Looking for a non-magnetic, strong, easily glued material
30/04/2022 08:36:57

Don, glad my input was of use. Dave W

I used to work for a seal-less pump manufacturer we manufactured our own magnetic drives, they used stainless steels of varying specifications to meet the product conditions, some of which were highly abrasive or corrosive, the magnetic drive operated through the stainless steels with no problems, my choice for this application would be the appropriate stainless steel.

Thread: Workshop warming
29/04/2022 14:43:50

I have just insulated a small storage shed that I built about three years ago, should have insulated it when I built it but that’s another story, the shed has no windows and is about 8 feet by 6 feet one wall is concrete block work and will be without insulation, the rest of the shed is wood framed covered in shiplap with insulation between the uprights. The reason for insulating it is that I store my beekeeping equipment in there, amongst other things, and contains sheets of beeswax which doesn’t tolerate being warmed when the sun shines. With only shiplap covering it gets very hot in there when the sun shines so I am using 50 mm Kingspan, bought 2 8x4 sheets this week and was surprised how much it has gone up recently, it cost £48.50 a sheet and a builder friend of mine advised me to buy it sooner rather than later because there is a further 20% price increase apparently in the pipeline. I probably need another sheet to finish the project and insulate the roof as well, which is probably next weeks job to do. My workshop, which is considerably bigger but the same construction was insulated when built with Celotex, 100 mm in the walls and roof, minimal heating with a small oil filled radiator and a humidifier used at nights on off peak electricity keeps the workshop comfortable and relatively low humidity. I would advise anyone contemplating building a workshop or upgrading a current one to go for as much insulation as possible, Celotex/Kingspan is my product of choice, and buy it sooner rather than later as prices are moving ever upwards. I have to a certain extent mitigated the increasing electricity charges because I have 4Kw of solar generation with 12 KWh of battery storage, doesn’t cover all my electricity needs but as they say every little helps, and of course the sun doesn’t shine very often in the winter so the solar generated in summer offsets power used in winter in the workshop.

Thread: Cheap stuff
26/04/2022 15:18:49

A few years ago I was picking up new, unused end mills and slot drills, some were top quality carbide, from eBay, they were advertised as items from individual sellers who were not selling professionally. My Best Buy was a top quality 16 mm carbide end mill, totally unused, I think I paid no more than a fiver for it. I wondered how so many new milling cutters were available on line and came to the conclusion that people working in engineering must have been putting them in their pockets and taking them home and then advertising on eBay. I managed to build up quite a store of end mills and slot drills but nowadays the supply has dried up and very few are advertised and usually the price is the same as retail. Dave W

Thread: Annoying Anonymous Phone Calls
18/04/2022 16:23:16

Peter, thanks for your input and yes it does make sense but our gp surgery unfortunately use the number withheld option and I don’t rate my chances at very good in trying to influence them otherwise.

Duncan, yes a good way to go but unfortunately a bit too late as my number is out there being exploited already so I am trying to find a way of blocking the numbers with 0843 codes and not having any success. Dave W

18/04/2022 13:06:04

So far in my research I have found that you can block all numbers that are not in your directory of numbers, if it’s not on your list it can be blocked, problem with that is we frequently get phonecalls from our doctors surgery, wife has a number of medical problems, and the surgery calls are always number withheld which means they would be blocked. It would be a solution if you could block calls that are prefixed with specific codes eg 0843. Still researching if that’s possible. Dave W

I keep getting annoying telephone calls on my mobile number, the calls all start with 0843 but the rest of the number changes each time the caller rings, the latest number that rung this morning was 0843 878 1165, the number rings about four rings then stops, if I am quick enough to answer before it cuts off there is no one there. It is extremely annoying because some days it rings three or four times, sometimes it goes a week between ringing. When it rings now I add the number to my blocked callers but when the number is different each time it rings that doesn’t stop future calls using a different number, the common factor with all these numbers is they all start with 0843, nothing else is the same on subsequent calls. The problem has been going on for about six months, that’s an awful lot of different numbers all starting with 0843 so it must be a machine that is dialling out somewhere, how does one sort out a problem like this and does anyone else have the same problem? Unfortunately nowadays invariably when one orders an item from an internet supplier they need your mobile number and it’s so easy for unscrupulous traders to sell on lists of mobile numbers which is probably where scammers get their numbers from. I live in hope that whoever or whatever is the source of these 0843 calls will eventually run out of numbers related to the 0843 code but there are probably many thousands to go yet. Dave W

Thread: Electromagnetic Wave Interference

I think that dialogue with NT should be the way forward and Howard has already emailed them with the details of the problem, perhaps after the Easter break a phone call would help provide the resolution. Dave W
