|Thread: surface grinder|
Also sold motorised as the Tormach PSG-612. Loved the video so I bought the cheap one
I replaced the "hawser", connecting the grinder to its counterbalance weight, with a 6mm chain.
I removed the strangely imprecise, right angle Z handle and fitted a 6mm ball screw where it used to be.
I love the idea that after diamond dressing the wheel you know its exact height above the table.
I want to motorise Z, as well as X and Y, but it is proving tricky.

|Thread: Paypal payment delay|
It used to be easy to refund on PayPal because they refunded their fee and I refunded the rest.
Then they changed the rules and stopped refunding their bit. Didn't stop the seller from wanting 100% and not one penny piece less though.
Either this seller is being generous or he has a much better deal from PayPal than I do.
Probably the latter, I am fairly convinced my purpose in life is to fund other folks dodgy get rich quick schemes
|Thread: Leveling machines|
I bought a cheap Chinese Engineer's level. Luckily it was very easy to fix when I discovered that the rubber bungs at either end were removable.
The pivot hole drilled through one end of the bubble assembly was hopelessly cock-eyed and it was instead supported by a bent wedge-thing crudely formed from a strip of Chinesium.
I removed the wedge-thing, drilled a new pivot hole through the other end and turned the assembly around.
I then had a quality tool at a bargain basement price, assuming you don't look at the non-adjustable crosswise bubble that is
|Thread: Bench grinder|
I did pop one out just to see if it was as easy as claimed.
I knew nothing about bench grinders so I typed, "Which bench grinder?" into Google and then bought a Metabo DS200.
|Thread: What Did You Do Today 2021|
I was changing a lot of optics. By some miracle I always seemed to guess correctly as to whether it was the photodiode or the LED that had failed.
Then I realised I wasn't changing the optic, I was changing the solder and always at the button cell end.
One leaky battery and the solder joint died. Still looked okay it just didn't conduct
|Thread: Best soldering iron for electronics|
I do a lot of soldering. Eventually, I got fed up with Chinese 852's. It's nice to have the hot air nozzle but the irons were very hit and miss on temperature and once a pad boils off the board it is nigh on impossible to put it back.
I eventually returned to the fold and got me the reasonably priced Weller WE1010 and have never looked back.
It features a timer so it is immune to being left on accidentally overnight.
|Thread: We thought the Aliens had landed …|
We have one of those up on Seaford head. It hums to itself and miraculously causes aircraft to turn 90 degrees as they pass overhead.
|Thread: working Damascus steel|
The blacksmith at Rodmell forge told me that when steel was in short supply due to WW2 the shepherds would bring him old shotgun barrels to be made into the Sussex leg crook. When he tried to reduce the diameter on Damascus barrels they came unwound. It was never actually welded.
Similarly, if you wind a Damascus barrel then rifle it, you are cutting across the grain of the Damascus and the rifling has no strength. A rifled Damascus barre starts with a tape wound core.
I have one of the original Liege Damascus shotgun barrel blanks Peter Dyson was selling off. It has a beautiful loopy pattern. Wonder if he has any left.
|Thread: Did I imagine that?|
My goodness, your gear pictures make me even more determined to cut involute teeth. What is wrong with me?
So many things to buy and my mill in pieces, whatever next?
I shall hope for 16DP then, sounds better than MOD1 already.
What material were you cutting to blunt HSS?
Do you think they might be high carbon steel dressed up as lamb?
Did I really just buy a set of M1 involute gear cutters for £34.49 on offer from Amazon with free shipping and delivery in 3 weeks? Perhaps I imagined it. I couldn't help myself. It was an involuntary burst of mouse clicking and all over before I knew what was happening.
I mean, what's the worst that can happen?

|Thread: Metal Suppliers|
Another vote for Rapid Metals. Free delivery with DHL if you spend enough and they will sell you little bits without cost penalties. Watch out for their 4mm sheet though, it's bent.
|Thread: Chinese drip feed oilers|
Of course, Old Muggin's here has a bag full of them
They need a bit of work in the throttle if you want it to shut off.
The top spring thing that uncovers the fill hole and holds the drip adjust wherever you left it, is a steel stamping with sharp edges so nothing about it is easy.
The screw thread at the bottom was not something I had in my collection of taps and dies.
What about those digital oilers with the interval and duration timers? Somebody stop me
|Thread: Uncertainty of Measurement [Global Warming]|
Remember, this is attribution, so there doesn't have to be any warming to make the temperature rise.
All you need is a fall during the calibration period, in this case 1850-1900.
Attribution science graphs.
"Attribution science" meaning any climate variation that the maker of the graph could not explain must be due to carbon dioxide and human activity.
A novel approach to science that will probably last at least 20 seconds beyond the point where the funding runs out
|Thread: Milling arbor sans keyway?|
Tell me about it
I have a couple of ISO30 ER32 collet chucks that I bought before I realised Warco had it wrong.
I will probably give them to my son, he can flog them on that auction site and make a few quid.
There are some tasty, low overhang, INT30 ER32 chucks out there. I got one and am looking for another.

I love it. I feel a deep need to cut gears, probably just a blood clot but it still has to happen
