Thanks guys I feel more prepared now, I have the stand to put box on set up already , I just wanted to shorten the cone because the base which I attached to wood didn't look like it would fit flush against tree. The cone was 24 inches long , with an 8inch base. The hole is about 2 and 1/2 inches in diameter on about a 4 inch bump, I just thought a smaller base would fit flatter against the 4 inch bump, I 'll try to remember pictures.
