I have read all the threads on the Presta and air compressors. I'm going to buy the following:

Someone in the family broke my floor pump. No one is fessing up. Everyone know how that goes. I have ordered a new pump, but I would like to get a backup for when the floor pump is not working. I'm also going to see if I can repair the pump to have as a backup.

But, I still have a question for all the experts out there. I have one of the schrader / presta adaptors. I have put the adaptors on as snug as I can and the Orinig is sealed, and I can't get the air to start out of the schrader chuck.

It looks like the pin in the middle of the scrader chuck is not getting depressed so that the air isn't released, and when I look at the presta pin. It is so far in the tool that it does not even come close to touching the schrader valve (This is probably not the issue). I have three different adaptors, and not one of them work with my shcrader chuck. It works fine for all the schrader tubes though.

So, does anyone know of a chuck you can use that will allow the air to open up to put air in the presta valve with the adaptor. Some gas stations work for this, but I don't want to pay $ for 2 minutes of air to repair my tires. i have about 5 and it is a big pain.
