Funnily enough the wheel chair sold today, had 4 people asking about it! thats £20 in the red wine fundBlobber said:
None of them seem to want it as its used or they already have a load, elf and safety I guess
My father had the same situation with a virtually new wheelchair when my mother died. He rang the hospital and they didn't want it. He went into the hospital pushing the wheelchair and got on the lift up to one of the wards, where he left it behind a door.
I'd be pretty sure its still being used!
It's not PB1, it's PB2PB1 bronze

Don't tell people that, you'll never sell your bars!It's not PB1, it's PB2
We bought a wheelchair for my wife, sadly she died before sitting in it. We gave it away on Freegle, the ungrateful so and so who took it, couldn't even say thank you. People huh?
No good deed goes unpunished.and she took them and closed the door without a word.
That's very similar to the nsk onesA straight handpiece for my dental drill;

I'm seriously impressed with the quality of it, all stainless, no exposed spinning chuck or anything (Only the actual cutting bit spins), a 1/4 turn of the barrel part to lock or release the bit. There's an internal brake too somehow, if the chuck isn't locked, or it's locked with nothing in it, the spindle won't turn, but put a 3/32" bit in it and it spins free as anything and dead true.. The blue band in it indicates it's a 1:1 speed, geared ones have either a green or red band to indicate speed reducing or speed increasing.
Looking through datasheets for the controllers these motors are designed to run on, I'm pretty confident it should be 24V, which unfortunately only gives me about 12k rpm, I took it up to 30v and noticed it getting warmer, but that could have just been from trying to load it up drilling holes in things. No load current is about 150mA, I managed to get it up to about 500mA ruining a piece of wood but the controller datasheets seem to imply it could draw up to 3.5A!
That's sort of what inspired it, I'm pretty sure the NSK micromotors are the same as their dental handpieces, in a different housings. Ideally I'd just buy an NSK system with all the accessories (I don't think I'll find a miniature belt grinder attachment for a dental motor...), but my hobby budget won't stretch to a tenth of what that would cost.That's very similar to the nsk ones
