That's a nifty solution. I'm glad mine hasn't needed any counter balancing, yet.
Loving the mods, shame I asked @Ricochet about his mods in another thread, would have been better suited here. I have pinched one of those ideas and am trying to find a B&Q store with the shed mate levelling feet, my local store didn't have any! My favoured spot in the garden isn't level, and whilst it's not absolutely detrimental to how the dob works of course, I just wanted a make it better, so I have cut a circular piece of 18mm ply ready for said levelling feet. I also need to have a move around in the shed which is close to my little preferred spot. In the winter months, it will make a good place to have the EP case under cover and will also be where I store the dob overnight following a session, makes more sense than anywhere else.
