Sherline CNC Mill: Limited Headroom Thereof

Cramped Headroom
Cramped Headroom

I had to drill a 1/4-inch hole in the Totally Featureless Clock’s case for the antenna jack. Fortunately, I have a 1/4-inch collet, because there was nowhere near enough room for the Jacobs chuck in there.

Removing the tooling plate wouldn’t help: the chuck setup needed another inch!

In truth, the headroom is rarely the limiting factor. Another inch or two of throat distance and maybe that much more Y travel would be nicer, while we’re at it.

Ah, well, it’s all a matter of tradeoffs. If the mill were much bigger, I’d just want to make bigger projects, right?

  1. Hi, when doing drilling on very large things on my mill I have turned the head 90 degrees and made the drilling action horizontally instead of vertically. Works pretty well on my Sherline 2010 mill. I guess it should work as well on the 5400.

    1. made the drilling action horizontally

      That’d work, although that hollow clock case stuck out much too far in all directions for any reasonable clamping on that little bitty table.

      I’m figuring out how to position a slitting saw to cut tubing and I think rotating the head as you do will be part of that: it’s much easier to clamp the tubing horizontally than vertically.
