|Thread: Does charging your car battery on fast charge damage it?|
I think the tale of high charge rates damaging batteries comes from when dealerships would stick an 100amp charger on a battery prior to a test drive, or leave the a high amp charger on for extended periods of time which will distort the plates heating the battery drying out the fluid. Years ago buying a second hand car from a back street dealer normally resulted in the car needing a new battery fairly quickly after purchase. Probably not such an issue nowadays with regulated & controlled charging from modern chargers.

|Thread: UK fires up old coal power plant as gas prices soar|
The use of UK sourced coal was stopped due to the high sulfur content which causes acid rain (now largely a thing of the past) the imported coal has a much lower sulfur content. This was one of the primary driving forces in the demise of the UK coal industry.
|Thread: Warco HV6 rotary table|
Not every factory has quality modern machine tools, some of those far eastern factories rely on old worn out poorly maintained second hand machines, the quality of the products are reflected in this. Also some of the components are probably produced in back street workshops, like every product in this modern world the big factories sub a lot smaller parts to little producers.
|Thread: Lathe query.|
be care with that switch fuse, that type may well have asbestos cloth behind the fuse carriers, don't pull the fuses out close the box isolate the feed to the box cut the conduit either side of the switch fuse double bag in plastic and take to your local recycling centre. Check if they take asbestos first.
If you are confident with your rewiring I would obtain a Siemens contractor and overload unit rated for your motor. You will have to be careful with the selection as the contactor coil voltage maybe different to the line voltage, do you have a transformer in circuit that will reduce the control voltage? The control voltage could be anything from 24v D.C. to 240v (phase & neutral) or full 415v.
Before you buy a contractor check if there is an overload unit attached to the original unit if there is and it has tripped it will prevent the contactor closing, there will be a reset button on one side of the overload to reset it. Reset it with the power off. If it trips again the setting could be wrong, it maybe an old oil dash pot type and needs the dash pots refilled with oil or you have a fault with the motor, or the motor/head is seized and it is an overloaded motor.

|Thread: Woodmaster Table Saw|
Old switch gear very often contains Asbestos, either chrysotile cloth behind the fuses or asbestos flash guards around the contacts. Don’t open the box just cut the conduit or cable either side remove the box place in plastic bag and place that bag in a bag -double bag and take to your recycling centre. They often have a hazardous waste container and will accept domestic waste such as this depending on your local council policy. If you open the box you risk contaminating your workshop as there is no knowing what the condition of the contents is or what is actually in there.
|Thread: Attaching a wooden disc to a Rotary Table without break through|
Glue four tenons under the disc to match the tee slot positions and place on the RT, number them and the slots so you can place it back in the same place each use. It won’t move under the pressure of a pen. No need to glue to the RT if the tenons are a good fit.
|Thread: A SIMPLE POINT !|
Isn't a bolt used in conjunction with a nut (& washer etc.) and a screw (machine, set, grub, shoulder etc.) is fitted to a threaded hole although there will be as many opinions on this as there are types of screws and bolts
|Thread: Vise/Vice advise|
I too have the wm18 milling machine, I have a Vertex VA5 which is an excellent vice, very well made with accurate jaws with next to zero jaw lift, expensive but this quality will be a one time buy.

its hard to say as it is a known cause of cancer - do you know of any model engineers who have died of cancer!!
Cadmium and its compounds are highly toxic and exposure to this metal is known to cause cancer and targets the body's cardiovascular, renal, gastrointestinal, neurological, reproductive, and respiratory systems.
Farming is going in a different direction the use of methane will become more normal: New Holland will add methane powered tractor to range in 2021 - AFDJ
the intention is to create energy neutral farms producing methane from animal & farm waste, there are already a number of farms selling methane to the national grid so it is a small step to fuel the tractors and other equipment in the near future.

|Thread: Lack of material and prices|
The shortage of materials, parts and finished goods isn't due to the border controls. The well-known company I work for which makes agricultural machinery has huge problems getting parts and materials we have over 80 million pounds of part finished machines waiting for parts, constant daily shortages resulting in production delays.
The border controls have added a day to the logistic pipeline which means adding a day to the lead time before the part is needed on the production line which hasn’t been a big problem. Finished goods into EU and parts out of EU has settled down to almost normal. We have registered as an AEO which allows unrestricted import of parts to us, which effectively makes us the border point for our parts.
The problem is getting parts and materials due to the months of backlog in supplier’s inventory due to Covid, this is around the world not just EU or UK. The whole pipeline from raw material to finished parts emptied out and have yet to fill, manufacturers have been reluctant step up production not knowing if more disruption is on the way, who wants to hold expensive stock if the market collapses as it did last year.
We stopped early on in the pandemic last March for 5 weeks, restarting at the beginning of May ’20 and haven’t stopped since, our order books are full, and production speed is up, the only thing holding us back is parts & material supply, and believe me we are prepared to pay the increased cost to secure supply.
This is a big business problem the plant I work in, which is one of 69 around the world, turns over nearly £1 Billion per year on its own, so the price we are prepared to pay to keep producing drives up the prices across the board.
To the argumentative bunch I know what I'm talking about, I’ve spent the last 15 months trying to keep a major UK factory going and in profit, you would not believe the amount spent in this effort.

|Thread: Portable vice - buying advice sought|
Get a B&D workmate and screw a decent vice to that, good strong multi-purpose work platform that can be folded away.
|Thread: A milling anomaly|
Could it be a combination of undersized cutter thread and worn collet thread allowing the cutter to pull through? Would it be worth checking how well the cutter screws into the collet.
|Thread: One place for all ???|
I would be asking myself, if the tool suppliers don't stock what I think I need is there a demand for it why doesn't anybody else need these tools and do you actually need them yourself or will ever use them.
They don't stock them because nobody uses them, there are probably better items that do the same job or its the wrong tool in the first place.
|Thread: Spares stock...|
I need a spare me, this one is worn out
