    Nicholas, you will lose 1" of mercury (on your gage) for every 1000
    feet of altitude. Therefore, you should only be able to get to 23"
    on your gage. You will need a vacuum that pulls at least 20 cfm to
    get consistent results. I may have a setup for you if you call me 
    at 1-888-652-8994. Doug
