 ===== Safety =====
-** THERE IS NO BELT GUARD FOR THE TOP OF THE MILL. ONE NEEDS TO BE FABRICATED **
+Always wear eye protection while using the mill. VHS-specific training / orientation is required. If used improperly, workpieces or pieces of cutting tools can be thrown around the shop at high velocity.
-Always wear eye protection while using the mill. Do not use the mill if you do not know how to use this type of machine. If used improperly; workpieces of pieces of cutting tools can be thrown around the shop at high velocity.
 ===== Specifications: Mill =====
-Mill is a Long Chang LC-15A. No specifications for this mill appear to be available online. The following information was measured from the mill and may be inaccurate.

+Please review this {{ :tool:lc15_lc30_manual.pdf | Basic Manual }}
-Spindle Taper: Measured ~3.215in long, 0.8in minor diameter, 0.95in major diameter. Very close to Morse #3
+The following information was measured from the mill and may be inaccurate.
+Spindle Taper: MT3 - Morse Taper #3

 ===== Notes =====
-To move mill head up and down (major vertical adjustment); you need to loosen two bolts on the right-hand-side of the head, and use the crank on the left-hand-side of the mill to raise or lower. Retighten securing bolts before use (when untightened, crank has huge slop).
+To move mill head up and down (major vertical adjustment); you need to loosen two nuts on the right-hand-side of the head, and use the crank on the left-hand-side of the mill to raise or lower. Retighten securing bolts before use (when loose, crank has huge slop).
 ===== Axes =====
 X/Y - handwheels on table
 Z - large grab handle on right of mill, or handwheel on front of mill. Black locking ring on grab-handle on right of mill engages/disengages handwheel. This axis can be locked via the small black lever on the front-left of the mill head.
-===== Tooling =====
+===== Fixtures =====
-- 1/4, 3/8, 1/2in collets
+The 3.5" swivel vise can be bolted to the table via T nuts / bolts. Never assume that the vise is aligned correctly; use a dial indicator to check.
-- Drill Chuck
-- (many more)
+We have a set of 1/2in T nuts + fingers + step blocks for the CNC mill that will also fit this mill.
+===== Tooling =====
+- Drill Chuck - at the moment, the only chuck key that fits is on the drill press in the Fab shop area.
+- 2x Offset boring heads
+- Fly cutter. Takes an HSS toolbit, ground to the correct profile
+- 1/4, 3/8 and 1/2 collets. Used to hold end mills, fly cutters, and the small boring head
+- 2.5" face mill. Needs to be replaced, as all the carbides are chipped, and are not available for purchase. Still works reasonably well
+- Drift keys. USe to remove the tooling from the spindle. See document (pending) for use.
+- (many more in varying condition)
+- (Most) tooling is located in the red toolbox in the end of the (pending) work bench.
+===== Speeds & Feeds =====
+Cutting speeds can be determined easily by using this {{:tool:cutting-speed-nomogram.png?linkonly|cutting speed nomogram}}. The {{:tool:lathe-cutting-speed.png?linkonly|original cutting speed nomogram}} came from Ian at the BCSME.
 ===== Tutorial =====
-A written tutorial won't suffice! Don't touch the machine unless you've received training or used similar equipment!
