    I am no machinist. Just a retired electrical engineer. I did this yesterday and it was hard.

    If you did that on a mill likely it was not Hard..it was Difficult.

    I made one cut with 1/8" carbide bit.
    I made the last cut with 1/4" carbide drill bit.

    Good job figuring it out! It gets more difficult when your new barrel is too large to fit through your indexer!
    I made a carbide cutter on my Deckel SO grinder for the proper angles. PSL's require the same relief groove so save your tool.

    This barrel is Lilja that was tapered for a Kimber 1.050" shank. It barely goes though the rotary table. 1937-mosin-6.5-vostok-lilja-boyds-timney-trijicon-20210730_174655.jpg

    I got that Lilja 3 groove barrel blank cheap, but the shank was too small for a Rem700 or M70 or 98 Mauser. But it was a candidate a 1903 Turk or a Mosin.

    I just finished another small shank project. A Bergara that I tapered down to fit in a 12 gauge bore.
