I have a 3 ' peppermilll to make and I'm not looking forward to drilling that hole:)
I may have to make up a extra long extension for the bit, or drill from both ends in.
should be fun.
Any tips are greatly appreciated

I always drill from both ends...any deviation is minimized at the ends and passed on to the middle where, unless it's a huge amount...should not be a factor. If the option exists, try to drill in segments of 8-12" and then glue it up. The longest I've done so far was 14". I had about 1/16" deviation at the center. Good luck!!

You could google search for a lamp auger bit, they're usually over 24", but not 3 feet. They're also pretty pricy, so it would depend on how many of these mills you plan to build.

I only need to make the one mill and it has to be solid with no glue ups 3'
I'm wondering if i could use the shaftless kit, I normally use the kits with the shaft for the 12" mills and down.
I may have to make a 18" bit extention in the sparky side of the shop

get one of the bit extensions from an electrical supply shop. my stepdad has tons of extensions so he could drill through a wall from one spot

Could the blank be made of two pieces, with the "hole" being a longitudinal groove between the two laminations? Have seen this done on several flatwork projects where a long hole is needed. Even flatwork guys can have a good idea once in a while!
