I gambled 40 sovs on this from Amazon.
Had a play and it's bloody great! The bead breaker works very well and the platform part holds the wheel securely, I've been doing tyres all wrong up until today. It's supposed to be bolted down to the floor, but I didn't fancy it permanently in my way for the odd bit of use, found an old frame to lash it onto that could then be screwed to some timbers or an old pallet.
This is what makes it a decent bit of kit, nice coarse acme thread on the collar that secures the hub for the levering and the jerking, the tugging and the twerking.
Not being sensible I tried it out first on a stupid low profile on a gaudy monkey metal wheel of a ridiculous modern wankbox, well if my brother leaves it in my yard it's going to get fucked with, obvious issue is that the locking collar and / or spider thing are going to gouge up the fancy chocolate rim, and people can be quite prissy about the fruity little trinkets, luckily I couldn't give less of a shite, even more luckily a bit of old wastepipe fitting that's to hand is perfect to cushion things.
And here's the delivered goods. I was working in a tight space for the sake of moving a car, but was ok, swung the lever left and right rather than round and round, I reckon when I use it next on a proper wheel it will be a piece of piss, especially if I get some tyre soap in.
