as long as your metal will fit on the stairs and you don't mind burning the carpet...

You'd need a speed controller as the stairlift is just on or off isn't it? You'd need to be able to adjust the speed for different thicknesses to get best results, but if you can do that it sounds like a brilliant idea.
yes you are right ,just need to understand speed controllers now
now im into PWMs just a few chips would be nice to go with the s/v
Had a quick look probably need to match the wattage and voltage
thanks for the heads up, bidding on a lift tonight might get lucky

basically it pulses the voltage, then i think you multiply the number of pulses by the frequency of the pulses to get the average voltage, which is what the output sees, although i haven't done a lot with pwm so in not entirely sure. Sounds about right though

Would modifying a boc pug to take a plasma torch be any easier idea see the sometimes on eBay easy enough to make the tracking up. Sold mine before I thought of the idea

Had a look at that , pretty wild man
interesting project and site, im amazed how long people spend in their workshops
bought a stanna stair lift complete for 99p two days later the person selling it said it was stolen, very annoying
so now bought a pavalux 240v reversable motor with reduction gearbox which turns at 33rpm , I tried a pwm 240v up to 40amp and that reduces the speed but also the power so that dosen't work for me , now I have been looking at stepped pulleys and can't believe the cost I would need two , I need to reduce to about 9rpm and one or two steps higher , this is to drive a swager with variable speeds, any ideas?

Not much help, but I'm intrigued. How on earth do you go about stealing a stannah stairlift?
I imagine step one is listing it on ebay without thinking about how much ££ you want for it. When only one person bids and wins it for 99p step two kicks in and you claim it was nicked...
240V AC motor or a typo and it's 24V DC? If it's a 240V AC motor many of the PWM AC motor speed controllers the internet spat out specified induction motors, this is mostly witchcraft to me but if you post more details of the motor and PWM controller you used those that understand witchcraft may be able help more...

It went like this, she said, "her husband was going to be away from the middle of the week, so he (intsead of me ) took the stanna out and laid it on the front drive beside the car , next morning it wasn't there" then they requested through ebay to cancel the sale giving no reason, I originaly on sunday said, I would take it out on tuesday , then on the tuesday, thats what they said, they sold another one that made £65 at the same time , seems all a bit fishy to me
ad said, 2000w 50-240v adjustable voltage regulater pwm ac motor control controler
my geared motor is 240v ac induction about 1/4 horse power,( the plate is missing)

Someone I know put a Range Rover classic chassis (with V5) on fleabay with a start price of 99p and only got one bid, at least he honoured the sale, although he did watch them struggle to get it out of his back garden
