Thread: Vacuum Pump Advice Please!

Are the vanes free to move in and out? They might be spring loaded or move out under centrifugal force.


Thread: Problems reading from a 3.5" floppy disc
23/09/2020 19:09:01

I seem to remember, very many years ago, buying an adaptor that fitted into a 3.5" drive and it allowed you read from one of the early style memory cards. Cost a fortune at the time.

Welcome Darren. Most electricians seem to be very good at turning their hands to other trades.

I'm getting the impression that Hermes have done a deal with Ebay and it's sellers. Most of my recent purchases have been delivered (more or less) by Hermes.

I think you might be correct. I have noticed a definite increase in things being delivered by Hermes et al that would have previously come by Royal Mail.

Hi MichaelG, thy are the cards my first digital camera required, which from what i can remember, were a bit pricy then compared with todays prices. I only have three, one each of, 16MB, 64MB and 128MB the latter still has space for 16 HQ photos. The camera is a Olympus C-3020 ZOOM. A good starter digital camera but I don't use it much now, although it does still work, but the inside of the front lens has some very fine strands of fungus on it but doesn't notice on any photo and it's probably not worth what it would cost to have it cleaned.

Regards Nick.

P.S. still got the box the camera came in and on the contents list it included the 16MB card.

+1 for the Olympus cameras. I still have a C5060WZ in full working order. It is a really beautifully made camera, when you pick it up it just oozes quality. Takes both multimedia style cards and compact flash. I wonder if there really is any value in these old style cards or is it just wishfull thinking by another ebayer.

Still have my trusty Fluke 77 DMM from the mid '80s

+1 for the Fluke 77, mine is still going strong after 34 years. The battery lasts for ages, I can count on one hand the number of times I have changed in it.

Double check the actual fuse holder itself. It could have come loose and rotated as you unscrewed it. The tag on the outside could have rotated and touched something.


Thread: Diamond Lap for sharpening Brazed TC tools

Another yea sayer here. I've had a suitable motor sitting on the shelf waiting for just something like this. A trip to see the tool man on Chesterfield flea market next Thursday should supply the lapping disc, he does lots of toolzone stuff.

I wonder if we have to import all the pulverised fuel ash (PFA) used to make Celcon blocks now we have closed all the coal fired power stations down. Good example of the law of unintended consequences. Same goes for all the Gypsum we used to make as a by product from desulphurisation plants on coal fired power stations.


Do you mean clinker blocks?

Celcon use aerated concrete to produce their lightweight blocks.

We still use FGD gypsum from power stations in the UK because of it's quality, the plasterboard companies buy the exclusive rights to claim it for production. They also invest in 'used' recycled gypsum which has already been through the building cycle.

Edited By Phil McAvity on 27/07/2020 11:28:13


No not clinker blocks, the much finer grained aerated blocks. The blocks are made from cement, lime, sand, pulverised fuel ash (PFA) and water. PFA is mixed with sand and water to form a slurry. This is then heated before being mixed with cement, lime and a small amount of aluminium sulphate powder. The aluminium reacts with the lime to form bubbles of hydrogen.

Phil H, Yes I totally agree with your comment '80 to 90% ok at half the price or cheaper but every single Chinese thing I have bought needs 'work''. I like most people buy Chinese stuff.


This is so true. It does seem to me that the Chinese are better at electronics engineering rather than mechanical engineering. Nearly all the assembled printed circuit boards I have purchased from China have been spot on but the mechanical bits do seem to require that extra bit of work. I actually quite enjoy stripping kit down and cleaning it and modifying it to my own satisfaction.

+1 for Tuecall. We have the stand alone Truecall unit and it has certainly proved its worth. For a small annual sum you can access it via the internet which means you could control it from your home without having to visit. You can set star callers who come through automatically and zap callers you definitely don't want. All the others have to give a name or number. The odd one gets through but it certainly blocks the majority.


Thread: Bench grinder wheel wobble
20/07/2020 22:40:25
Posted by Andy Shepherdson on 20/07/2020 20:20:00:

My old 6” Aldi special is a different story. I fancy putting a CBN and diamond wheel on it. The supplied washers seem part of the problem, has anyone managed to method to get the wheels to run true.


I am in the same boat with a Lidl 6" grinder/linisher. The original wheel is not perfect but at least is usable. I bought a high quality fine grit grinding wheel, and no matter what I try the assembly is so out of balance that I dare not attempt to use it. The wheel itself appears to be OK when checking its static balance. As Andy says the washers may be part of the problem but from the crude measurements I have made I suspect that the shaft may be bent. I have reached the stage now with it that I am going to replace the grinding wheel with a wire brush and upgrade to a better quality bench grinder.


Thread: Science Museum needs help identifying mystery objects

I've still got a Hobbies treadle fretsaw and it is in full working order. Does not appear to have any financial value. I don't think I have used it the last 50 odd years. It was a Christmas present when I was a youngster. It's strange when you see items you own are now classed as museum pieces.

I am pretty sure that if you need to cut off the factory fitted moulded plug from a domestic appliance for any reason and fit a replacement plug you can invalidate any warranty .....

But I stand to be corrected

Regards to all

The safety officer at one on Englands large universities wouldn't have a moulded plug on site. They were all immediately cut off and rewirable ones fitted.

We trained our reps at work how to fit a 13 amp plug and provided them with a cerificate to show they were competent. It was always interesting to see the reaction of a customers safety officer when they queried if our guy was allowed to fit a plug on the equipment he was delivering. Never had any problems once the certificate was presented.


Thread: Is Iron / Steel endlessly recyclable ?

Most steel is made by blending a mixture of scrap and iron from a blast furnace. I empty my workshop scrap bin into the metal skip at my local recycling cente.


Does it matter if you mix up ferrous and aluminium?

At work and at the local recycling centre there are separate bins for ferrous and non ferrous scrap. There is a huge different in even the scrap value. You are unlikely to recover the cost of the petrol taking steel to a scrap merchant, but other materials can certainly raise enough money for a good night out. Don't think aluminium is very high but lead and copper certainly are.

Now be honest

You were going to get it anyway 'cos it's fab

You will not regret it. Best thing you can do to upgrade a mill. I got the Z axis option when I upgraded mine, not quite sure how useful it it is as I generally use the built in quill DRO but the X and Y are absolutely fabulous.

The ad lists a “monodex sheet metal cutter” how many readers remember or owned one of these, it was a very crude shearing device which was extraordinarily hard on your hands to use, I had one and during a recent workshop reorganisation I came across it, surprising how many gimmicky tools there were on the market then.
Dave W

I've still got one of these. Haven't used it for years but it has had a lot of use in times gone by.
