I had an issue with my artificial Christmas tree stand in that the screw ports to keep the stand stable had worn out (the tree is probably 5 years old). Therefore the screws to keep the tree in place were loose and couldn’t be used at all. This led to the tree stand collapsing on its own and the whole tree falling over. You can see a picture of the stand which kept falling over below.
To fix this problem I decided to add a stabilizer to the tree stand. The stabilizer was a block of wood, where I cut a hole down the middle to fit the middle part of the stand and also cut spaces for the legs. I used a spade bit in a power drill to cut the hole and used a Mitre say to cut the spaces for the legs. The stabilizer holds the tree stand in place so that the legs can’t move (and therefore they can’t collapse). I also spray painted the stabilizer green to match the tree.
Overall I am really happy with how the tree stand support came out. Your can see more detail on how to build it in the following video:
