Isn't the twist drill = wobbly hole something to do with feed speed and material thickness?
It's all the factors; material properties, workpiece geometry, workholding and machine kinematics, drill grind geometry, drill material, feeds and speeds. In the end, a drill is a tool for roughing out a hole which is approximately circular, approximately the desired size and approximately in the right place, although if you dial in the combination of the above factors for a particular case you can get close enough for government work.

Slightly off topic but loads of people had spring punches when I lived in Manchester quite a few years ago..... Good for putting in the side windows of cars apparently

Dormer are the only drill bits worth buying. Buy a generic multipack so you’re covered on all sizes then just get multiples of stuff you’ll use every day. I have managed to resharpen cheap ones down to about 3.5mm but they’re a bit wonky usually.
I meant the bit of leather to act as a pad for hammering/working against, not for cutting washers.Also, if you have the space a little hobby pillar drill is a game changer - they come up in Lidl/Aldi sometimes for cheap.
We have a big 1970s Meddings pillar drill at work, it’s a bit scary but does a great job. I don’t really drill metal by hand anymore tbh. -

Meddings pillar drill
Been after one of these for a while, or a Fobco for the garage but they all seem to be miles away. Would like something sturdy so I can eventually get a 2 way milling table.

Is that just to cut a steerer tube? Or are you taking up plumbing?

Also not bad for trimming bars

I have one of these already for hoses.

The cheapest set I can find online in France (19 bits, TiN coated HSS) is 86€. Is that normal?
Gotcha about the leather. I have a few pieces of wood laying around, a cutting mat and some EVA foam, so I think I'll be fine for now.
And yes, a pillar drill would be dreamy, but alas as an apartment dweller who greatly needs to reduce the amount of things he owns, I'll stick with the hand drill for now. It's also not super practical for mudguards, we have two big ones at work and I couldn't drill them with the pillar drill, I think the curvature made it impossible because it was hitting the body of the drill.

If you need to fit awkwardly shaped workpieces into the throat area, you sometimes have to use the radial arm drill

I'll make sure to consider it after my next move ;)
All jokes aside, my dad owns a Cincinatti lathe and a mill, wish he'd put them back in working order, alas I'm too far away to help him!

Turbine blade
There's no way that's a turbine for anything. I suspect it's for some sort of mixer.

Found the description:
Cincinnati Bickford radial drill shown drilling shaft collars in large Series 7000 wheel to be used for pelletizing of Taconite ore. The multitude of bolts seen in the radial blades are holding in place thin renewable wear blades for this abrasive job

I'm after a new toolbox for bike tools specifically. Any forum recommendations? Ideally I'd like one on wheels, vertical stacking type (like tradesmen use) as the storage in our shed doesn't have particularly deep shelving, maybe with some trays. Tool fans on here seem to like the foam cutout posh ones, should I really be going for those?

They are good for seeing at a glance that you have everything packed in place/forgotten or lose something important mid-job

Having a particular place for tools such that you can see at a glance if it's there, is invaluable, especially in a mobile context. And if you forget you own a tool, you might as well not own it.

The planning is also useful. Highlights what you need and use, what you don’t have, and what you don’t need.
I need to redo my boxes as some tools are in the wrong box, and I want to add some tools and remove others.
I think it takes a few iterations to get it right, but my “stick in the car” box would enable me to fix most things, add box two and I can build a bike or totally strip and service one.
Isn't the twist drill = wobbly hole something to do with feed speed and material thickness?
I'm pish at drilling holes where I want them but with the set that I have I can drill them round enough. Started out as a Bosch set but I've replaced various ones as I've snapped them, blunted them etc.
Think a step drill is meant to be much better for roundness if that helps?
