You mentioned that you got a head for the pump on line. I would like to get a head for my pump that would fit a schrader valve. I want the head to clamp onto the valve.
What I want to do is use a presta to schrader adapter and use a joe blow pump with its own pressure gauge.
I have seen some of the expensive bike pump heads that cost as much as $80. This seems quite high. I keep thinking that I can get a small electric compressor with a schrader clamp on head for a lot less than $80 and once the compressor wore out I could then take the schrader clamp on head off the compressor and use it on my hand pump.
So is there anyway that I can cheaply get some parts to assemble my contraption.
