I have a floor pump that does a good job setting tubeless beads (Specialized Airtool specifically for mtbs), but I got tire off pumping.
I took one of these:http://www.harborfreight.com/pistol-gri ... 68270.html
Cut off the end that attaches to the schrader valve and than replaced it with one of these heads:http://www.nashbar.com/bikes/Product_10 ... 1___204807
That isn't the exact pump repair part, but you should get the idea. The part must have the compression type fitting that unscrews.
Here is my new inflator:
Works GREAT. I don't rely on the cheapo gauge from HF to be accurate, so I only use it to set the bead than I use my floor pump to set the pressure.
