Warping using a rigid heddle loom on a stand

I have a question. I have an 16" Ashford rigid heddle loom with a stand. I've previous warped it by taking the loom itself and pegging it to a table, but doing that kills my back and makes warping difficult. I thought I would try warping it on the stand, but I'm concerned about the stand moving around and messing up the job. Is there anything I should do or know?
