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.

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

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

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

Fascinating. You might think it would make more sense to omit the keyway from the saw rather than the arbor.

Could I be up against some weird H&S thing?

The Warco Ad confused me. ISO30 lacks the driving dogs, whatever they are called, so this is INT30 which has them. There is also BT30 for auto tool changers but it isn't that either.

I think I have to cut the keyway to keep it cushty, but if I can get away without then I am safe to buy a set of involute cutters and see how big the keyway needs to be.

I have a 6mm broach so I am hoping it's a 6

No it is INT30, I have a problem with my brain

I bought a new Warco HV mill and I love it to bits, lots of bits, it is all in pieces but slowly coming back together.

It came with two horizontal spindles, 22mm and 27mm.

The 27mm has a keyway while the 22mm has none.

Is that normal? I have no experience.

I notice that gear cutter bores seem to depend on the Modulus. At M2.75 they make the leap from 22 to 27mm bore. I wondered if perhaps the smaller sizes need less torque? Seems unlikely.

Perhaps you are expected to cut your own choice of keyway. This could be catch 22 if all the milling cutters that might cut the keyway are bored 22 because they are considered pathetically small out there in the real world

RDG tools have a 1" INT50 spindle that would fit and lots of DP size cutters to go on it. Unfortunately, they forget to say if it has a keyway and I have become suspicious. Also, does INT50 imply it wants a 40mm support bushing at t'other end?

Too many questions

The £60 one on eBay?

I was a bit puzzled by mine until I figured out I had to remove the blue plastic ring. It didn't want to come off, snapped in half when I insisted,

I haven't used it yet but it seems okay, maybe you got a dud.

I reach for one of my trusty 12mm Dormer TiCN Coated 3 Flute Rippers when things start to get tedious.

There are cheaper options which work just as well, but I got a deal on the Dormers

I realised that I don't actually need to lift machines very far to move them around my garage, an inch is overkill.

I took two lengths of 2" x 4" box section, fitted a heavy-duty castor to all four ends and adapted the machines so that the act of bolting them to the box sections lifts them 3/4" off the floor.

I still have jacks, engine hoist, 2.5-ton pallet truck, etc. but the box sections are my favorite..

If it was wheel locks then you would go for Bolek Maciaszczyk and his Facebook page Matchlock and Wheellock Guns. He was offering a course on making a wheel lock, maybe still does. He is very much into geometry, the workmanship is top notch.

I have an unlicensed, antique blunderbuss collection. The police swarm over me occasionally but they have yet to cart me away...

Touch wood

In the days before H&S schoolchildren were invited to etch glass at home using HF extracted from teeth

Could you put an extra, caustic proof layer below the etch resist and develop that in a second tank?

A hydraulic press sounds like a good idea to me but I am officially bonkers

They sell precision ground EN1A round bar. Never seen it anywhere else.

Should they stop selling it, is there anywhere else?

I unscrewed the front. right foot until the DTI showed about a 0.0008" error.

I repeated the skim cut and measured it twice, using my new found skill for reading Vernier micrometers

Left-hand end 1.5696" or 1.5695"

Right-hand end 1.5698" and 1.5698" again

Will it stay that way?

26 thou on the screw moved it 1.3 thou on the diameter which is 20:1
