I've got a Minoura one. Bombproof. Think it is the 4000 model. Has a nice little tray on the top, that you forget is there and then spend hours trying to work out where you put a bolt or somesuch vital fastener. Can also be used for putting tea on too.
Bottom brackets on a workstand.
I'm assuming you were applying the technical force known as 'giving it some'? Workstand ain't gonna help. Stubborn BBs trick: go out to the garden, lay your trusty steed on the lawn (nice and soft), apply tool to BB. By doing it this way you can put you upper body weight onto the BB tool, keeping it in place, whilst allowing you to use your other hand to 'giving it some'. If you try this job with the bike vertical you can't use your bodyweight to keep the tool in place.
(My other top tip - when removing chain ring bolts wear gardening gloves. Learnt that one from experience)
Workstands are brilliant, save loads of hassle, and a sore back. But I really wouldn't trust a 'mobile' stand to any job that involves brute force or an engineer's hammer. (A bike shop stand fixed to the floor is a different matter).
Why do I ride a Pace - it's all that bl**dy sheep's fault
