When I was building a very elaborate swing/play yard for the grandkids, I had to do some end grain drilling and I had to get the holes straight. To accomplish my task, I got blocks of wood the same dimensions as my posts. The blocks were short enough to place on my drill press table and I drilled my desired holes straight down. On the job site, I sandwiched the blocks between long boards and clamped the setup on the ends of my posts. This worked well for me.
Its' never hot or cold in New Hampshire... its' always seasonal.
