Does anyone want one of these?

NJD Carpeted 18" 600W Professional Bass Speaker Cabinet

It's located in Manchester, pick up only due to size and weight.

It was bought second hand as an ex display model about two years ago.
Since then it has only been used as a table (I couldn't afford an amp).
It was a stupid/pissed ebay impulse purchase and I want rid asap.

Pickup in M4, probably wont fit on the back of a bike.
£100 ono

Shit the bed. Mine isn't quite as pristine but that is daft money.

i'll give you £300 for yours!

the one above went for £531

£100? that's how much I paid for mine ;-)

Gone. A prize if you guess how much.

Wanted:

• 130 BCD inner chainring, 38-44 tooth. prefereably shimano or of decent quality. Someone must have one laying about after going SS?
  
• 90's Road pedals, something used but decent with metal cages and straps?
  
  

Ta very much

woo, interested in the dating of this as it looks to be an identical frame to mine.

A variety of bikes at Salford University:

• Naked/rusty brakeless track frame with black components
  
• Converted rossin
  
• purple/pink/white thing with white deep v
  
• white red and blue raleigh conversion ridden/written off by Andy King
  
• any single speed/fixed bike thats been outside newton in the last 4 years

Does anyone have a mixte/lightweight ladies roadbike they wish to sell? looking for something to suit a lady of around 5'10". Cheers

fixie track wood effect frame and forks

Looks horrid but could be a good respray project

"the handel bars are from the 1940s so i am tulled. the frame from what i can remember are i late to 60s to mid 70s carlton but i dont relay no just going by what i can remember. the frame is covered with wood effect FABLON i built this up over the summer built up with white rims and saddel looked sick. any way this is what it is a very nice frame and forks. there are i cupple of small marks her and there and the chrome on the bars has some pitting"

God give me strength

thanks for the soap holder tip!

sweet. I have acquired a similar frame, Olympic sprint road track, identical decals. Did you acquire this with the parts all on it? I understand from the link below that the frames were sold as separate unities and not as complete bikes, are you sure its from 1970?

I use 700c wheels on mine, and short reach brakes. unfortunately non period components. one day maybe.

do you want a air compressor, or a leaf blower? mechanically wise If you want to compress the air then thast a bit more difficult. leaf blower is simple, replace rear wheel with a fan and pedal, but I dout a you could create the pressure to use a valve or anything. to give a idea of how much air you could move with a 20" fan a gear ratio of 48-15 pedalling at 60RPM it would move over 12038RPM a minuite (if my maths is right). Not sure whether thats a suitable ratio, but I'd guess a fan would give less resistence than a wheel, could be very wrong though..... similar RPM 20" fans deliver up to 1.57 metres cubes of air per second.

if you want to compress the air you'd want to build something that works similar to a bike pump and innertube valve. you'd need some cams and cogs and what not to convert the rotation into linier movement of the piston. Its a bit more complex but cooler than a big fan.

mannn.... I dont have anything else to do but look up fans and stuff.

Cheers for the reply, looking for something that can fill a large volume quickly as apposed to something that can deliver high pressure. Suppose a compressor is not what I need. I think I'm going to try and attach a roller to the axle of a leaf blower impeller and combine with a trainer stand, that no bikes will be harmed!

Cheers

Thanks for the reply rhb, those links will prove useful. I think we're going to try and avoid converting to electrical energy and try and keep it mechanical, I think somehow linking the drive to the impeller of a leaf blower. A bit like a turbo trainer I guess!

anyone?

that airhub thing is wild!

Hi, I'm looking for a bike powered air compressor, I understand some people on here may have experience of converting pedal power to electricity, noise and other things so advice would also be much appreciated.

Myself and some colleagues (from the University of Salfords Acoustic Research Center) are doing a science demo at a summer festival and we need way of inflating the worlds largest whoopee cushion using renewable sources. Blowing is out of the question so we're considering using bike power.

whoopee cushion

So does anyone have any experience with making a pedal powered air compressor/pump?
