    Thanks Bob, Great idea, very relevant for me. My Hardinge horizontal has a Bridgeport M head that I mounted on the 2" overarm. I've only ever used the head aligned vertically. The other day I needed to incline the head 37 degrees off vertical. Without thinking I loosened the overarm clamps to gently make the adjustment and wham, the head being very top heavy swung instantly about 90 degrees stopping when the motor hit part of the mill. Luckily no damage to anything. I have a spare gearboxto donate to the project.
    Thanks - making stuff would not be half as much fun without the acknowledgement of you guys.

    When it's exactly 37* that you need, it's really tricky bumping it there! The motor hitting was probably the very best outcome.

    Bob, Wow! now that's being creative with salvaged stuff. I loved the photo of the gear box pieces, me thinks you should frame it and hang it on your shop wall. Cutting the worm wheel, boring and splitting it was a hell of an idea and it looks great. Nicely done, great photos, clear description and good followup to the comments. Ron
    Not on the shop wall, but it is in the Wallpaper folder for my Windows desk top.

    I do think that I will print, frame, & hang your post. I appreciate it, thanks.

    That way you can adjust the head with one finger.

    My worm adjust is easier to get right on the needed adjustment than your finger......😉 Unless you just "give it" the finger.... That's easier, but less productive.

    It's far easier than you think.

    But your approach is very practical, works just as well, and uses available materials. I like it.

    Nice, with the added bonus that there is no danger of loosing control of the head when loosening the clamps. I will be looking out for a reduction gearbox to mod the Tom Senior light vertical.
    Yes, that too. Otherwise it's a bit of game to keep the clamps loose enough to adjust but not lose control.

    Thanks. I'll be much more adventuresome with what I have laying around, than with something I have to buy. I never really know if something's going to work out & I hate to have wasted something I bought. Not rational, but there it is.

    I laughed out loud when I read that and scrolled to the next picture. Great job Bob, I bet that's a treat to use now.
    When I cleaned up & saw that pile of chips, I knew I had a picture.

    I did a similar deal to the Benchmaster. Had to make all the parts, since I had no handy gearbox. Works very well. You'll like yours.

    The only real difference in principle is that I cut a keyway in the arm, and trapped a key in the worm gear, so I can move it in and out without messing with the gearbox.

    Thank you! It's fun making stuff, and it's also fun sharing on HSM.
