Spindle holder for 1.5kw Chinese spindle.

Jonathan,

Do you think that mount is strong enough? it looks to be very thin near the clamping bolt (If my maths is right, 4.7mm) and you have a sharp internal corner at this point too. With this stress concentration and the cyclical loading that a spindle typically gets, I wouldn't expect it to be too long before a crack appears.

Yes I thought that looked like a weak point when I'd made it. Once it's clamped on to the spindle it can't bend, so fatigue shouldn't be an issue. It seems perfectly solid.
That's why on the next version (last photo) I rounded off that corner and moved it further from the spindle to make it stronger. Changing the drawing is not a problem.

If it breaks naturally I would replace it free of charge.

Possibly a bit late now, but just in case anyone reads this and is interested in one here's the 'latest version' without the aforementioned weaker point:
