35 buck Chinese Machinist's Level overhaul and cralibation (!)

[DIYSwede]

Not so much going on with this since I've had a busy semester startup at my Uni job.

But to get the vial tube properly hinged on the two set screws within the tool tube,
there's a pair of tiny holes to be drilled pretty exactly: both lengthwise and peripherally.
And as I'm not yet have a proper chuck indexing system in my walk-in closet workshop,
I had to wing something Q & D together, to align my 4-jaw horizontally:



Just a piece of extruded profile from a crashed hard drive, milled to 82,21 mm height.
Then crudely cut sides and notch to allow for the bottom jaw and up to max 60 mm pieces in the chuck.
Snaps under and locks (thru the foot's springiness) the 4-jaw at 90 deg intervals:



Then, with the toolpost drill, centre drill the tube at just the right place:



Next: Mere rust prevention paint job, assembly and "cralibation".
