How do you attach the central pipe to the base? The pipe I got are all OD 4-1/2" with inner diameter 4". while the drawing says the hole in the base is 4-1/4". Does the pipe go through all the way to the second plywood?

Also I am little confused with the end caps? one end cap is needed for the to attach the target vision, but where does the second one go? and also it appears that the caps are slightly rounded, does the vision target mount properly?

Sorry to ask a lot of questions, but we need help, our first year in FRC.

Thanks in advance for any help.
