Ya I was going to make a slip leg to do the same . But Think i mite do the bolt and nut now . Thanksgood looking stand.
on the ones I made I welded a nut on the bottom of each leg. that way you can just screw the bolts in or out of each leg to make leveling the stand a snap.
In it for a little of it all . I have a 20 acre peach orchard that I have started have it a little over a 1/4 planted and will finish planting it the first of next year . So I need pollination . And need the honey also . My goal is a 100 hives or so .From magnolia here! you have quite the set up! Sounds like you will be spending a lot of time with bees! Are you in it for the honey? Pollination of flowers or fruit trees? I get my first nuc in a week. I will have all of my hives sitting on palets since I get them free from work. Wish you luck!!
