[Greenbuilding] bike pump

[Stephen Collette]

John,

Could you not just weld a bike cog on a little 1/4 horse motor and  
attach it by chain to the bike? If you put a whole back sprocket on  
you could get various pressures/height pumping as required based on  
some trial and errors. That would be the most straight forward thing  
to do I suspect. Bike shops usually have some left over sprockets that  
have some teeth missing or stuff, that you could pick up for free or  
nominal. Figure a temporary way to fasten it until you determine the  
size you need. If you can do that input/output calculations in your  
head or on your computer, you might be able to rough out what size  
gear you need to make things close, then tweak from there.
