Currently slipping some one tons under the ole girl and would very much love to hack and tap the rear output to eliminate the slip yoke. No doubt the output shaft is hardened but I'm curious if I whack an inch or so of shaft off would it be easier to drill? I've seen a couple of DIY examples of where they cut off an inch or so of shaft, I assume because the material is softer and easier to drill?? I bought several new cobalt bits and went at the shaft today......I doubt I even scratched the surface...lol. Anyway, just wanted to check to see if anyone had any knowledge before I went full experimental.
