Looks like a Smith and Wesson .44 round. Is Clint Eastwood filming anywhere nearby?

Dunno what that is, but I had a bizzare puncture the other day that cost me a new tyre. It had 4" nail through it.

Now that may not sound all that strange, until I tell you the head was inside the tyre with the pointy bit on the outside. work that one out ?

Cap screw or torx screw .

I once had a 6mm hex driver punch a hole a tyre - it was the long type you use in a drill/driver , the front tyre must have flicked it up when it ran over it and it landed at just tue right angle for it to puncture the back tyre . The other one was when i got a new car i took the entry to my drive a fraction wider than usual and as my water meter is buried in a cut out in the concrete driveway i ran over it and the shaft for the shut off valve went straight through a brand new tyre - i have now fabricated a cover for the meter !

It's the tip of Clint Eastwood's finger which got sheared off when you drove into him in his wheelchair.

This was annoying as with a Smart I had no spare tyre.

Ah, 'hippy crack', N2O - you have no doubt parked in a quiet corner of a public car park, where the sniffers gather.

I suspect some smart Alec deliberately wedged it under your tyre at an angle, so it did what it did and penetrated the tyre.

Plenty down here too!

My guess it was wedged deliberately - their shape means it is unlikely one will flip up if driven over.

Did you park in a multi storey car park prior to discovering it?

Pointy end just right for wedging in the tread gap, my guess deliberate.

Can I claim my prize? Someone said it is a Hardinge HLV-H lathe?

Seriously, the gutters are littered with these cartridges around the Cardiff/Newport area. I see them lying there as I cycle in to work.

Is your Comet back in one piece now?
