That shonky old steel plate you used to grind for hours on end is non magnetic....Hows that you say? 😳🤔
Heat it up to the temperature needed to harden it, it’s molecules realign themselves and it’s no longer magnetic. Good indication if you have heated it up hot enough to harden it. Once it cools down again,it’s magnetic again. Random, useless information 🤣🤣
It was definitely magnetic when I was grinding it although it didn't seem so when you forget to turn the chuck on 😂 😂
Incidentally Saxon Steels has now ceased trading as of last week. Just clearing their shelves to send over to Sheffield Gauge Plate. Don't know if you've dealt with them at all but I wouldn't if you can help it.
I hate seeing these empty industrial buildings, I know its progress and all that but it makes you wonder
A lot of it is down to the buy cheap, disposable society we’ve become. Gone are the days where a joiner would buy the best saw he could afford and know it will last him. Pick one up for a fiver and chuck it after a couple of weeks to get another. A bloke I worked with used to work at Neill tools in Sheffield. Owner of Spear & Jackson, Moore & Wright and others. They also made world class hacksaw blades which is where he worked. The entire division was shipped out to China where they couldn’t work out why when they did everything the same their blades came out like chocolate. He was out there for 6 months watching them scratch their heads whilst all the time knowing it was down to the calorific value of their gas in the furnaces not being as high as ours. Left em to it.

I'm glad I have a stock of early 80's eclipse blades, that my dad acquired from LR Solihull.
Yes I seem to recall Eclipse were the ones. When they were in Sheffield they actually spent a million quid on research to design the perfect tooth pitch and won several awards for their blades. Right before they shut and moved over to COVID land.
He worked there for some years and got to work one day to find the whole place burned down. Some fitters had been cutting a steal I beam up in a storage area where it poked through a wall. They’d used a cutting torch, got the job done and gone home. They didn’t check the other side of the wall where there were cardboard boxes stacked against the beam which got a bit toasty and went up.
Customer “ Johnny,we need an oil pump” Me “ Hmm. This is like deja vu. Sure we had this conversation before. Not really economically viable to make just one “ Customer” We are not alone” Me” WHAT? Intelligent life on Mars?” Customer “ 🤣🤣🤣. No. We need two, Rob wants two and Brian wants one” Me. “ World domination in a specific oil pump market achieved.🤣🤣. Tell you what. On a job like this,things can go wrong. Here’s the deal. You want five in total. I will make five housings and a spare. If the sixth housing gets to the end unscathed,you pay for it too” Customer “Deal. We have a good set of gears that would go again, so will happily take a sixth housing. We will send what we have so you can reverse engineer everything.
A random box of heavily corroded aluminium oil pump housings,gears and base plates arrived the following day. Couple of days to measure and draw it all up. Aluminium for the housings ordered. Had some left over cast iron that I could use for the base plates. So milled them down, poked some holes in them and bunged them on the surface grinder.
Aluminium blocks arrived so I got machining Fairly intricate when you really start looking All six reached the ends with no machining errors light beadblast on the outside before being sent for clear anodising My mate Trev delivered the gears Assembled and ready for testing
I hope you include a 'signature', like mouseman furniture
A tiny Phallus perhaps, scribed into an inner oil gallery, akin to the old TVR folks hidden musings...or the famous JB Quiff placed on every surface big enough to fit it

Fairly recently a member of this Parish sent a Porsche cylinder head away for blasting. It came back pretty clean,but with a bent fin. On trying to straighten the fin,the hamfisted bloke totally buggered it , ( He could have had the lightest touch,he still would of buggered it. Because Porsche air cooled head 🤣🤣🤣) Any way,in an effort to avoid Oiltankgate 2, I offered to have a go at repairing it. It was hastily thrown in a box, crudely held down with mismatched fasteners and had the lid very haphazardly fixed to the box, and posted to me. Quite shocking really....😉 Anyway,after leaving it for a month or so to make sure no other fins were going to fall off,( you can never be too careful with air cooled heads), I eventually got around to doing something about it. First off I filed the broken fin down that it had a nice Vee in it,with only about half a millimetre of original shape and size material left to locate it. Old machine knives from a bog roll factory were used to space the fin up to the correct height( it’s important to use the correct tool for the job you know). I figured these Knives would be perfect for the job,ensuring the fin didn’t fall off again,as they are used to put the perforations into toilet paper,and when have you ever known cheap ,One ply bog roll to ever tear on the perforations? Genius move or what? 🤣🤣 Then I fired the laser welder up and spent a couple of hours shooting it to within a inch of its life. Precision or what? Fin firmly attached again
Then replaced the substandard fixings,replacing the mis matched nyloc nuts and standard nut,for brand new,secondhand,never been raced or rallied nuts I found stored in a skip. Tightened down to manufacturers specifications, ( kin tight plus three turns to make sure they don’t fall off ) Then it was a simple case of fixing the lid of the box on properly,not in the slovenly manner in which it arrived. Please note orientation of the screws, this is the correct way with the slots aligned, it helps Neanderthal Porsche owners remember how to use a screwdriver,and saves having to teach them where the slot in the screw is,every time 🤣🤣🤣

Very, very nice & as expected excellent workmanship but makes me happy that I didn't send the vintage Jowett engine barrel (also for laser welding) in a specifically built case or box does this mean that teaboy has been busy in his workshop with the infamous oil tank whilst you've been busy with gluing his fins back together or has he been busy with yet further oil tank distraction policies
