GRINDING STEPS. FOR BEST RESULTS & SAFETY, DUPLICATE HAND AND FINGER POSIITONS AS SHOWN.
STEP 1. Select desired lip clearance and point angles and elevate anti-shift stop to contact lower bed. For full details on angular settings, see the plaque that's attached to the motor's side. STEP 2: INDEXING Begin with left lip DECLINING down across baffle lines and flute edge in contact with Locater's inclined plane Thumb on LEFT flute edge presses drill lightly against locater. RIGHT thumb applies steady forward pressure on cube to spiral lip into alignment with baffle line. (Avoid point and baffle contact.) For tiny drills, dampening lever (P1) takes place of left thumb. After Indexing, LEFT hand carefully tightens Back Stop. Before sharpening the drill, be sure there's contact with flute edge against locater's inclined plane and drill's rear against cube.

STEP 3: With motor OFF, establish point to wheel & screw tip to lower bed's rear edge contact & rotate tension bar CLOCKWISE to increase thread tension. GRINDING DRILLS under 3/16" P1: (For larger drills proceed to next LOCATER paragraph). Align drill point in wheel area as shown. Lock swing assembly, snug dampening lever firmly against drill's body, start HAND POSITIONS motor and back off feed screw VERY SLOWLY while left hand FOR DRILLS 1-1/2 TO 3 presses mechanism downward and forward until wheel sparks out. P3 Rotate drill and FIRMLY twist it into locater while PRESSING drill back against cube, retighten lever and job's completed. GRINDING THE LARGER DRILLS (P2 & P3) HOLD IT!! READ the print in P2 & 3. Draw back Drill Bed to clear the wheel, back off feed screw for metal removal, energize motor and press assembly forward. LEFT hand thumb applies LIGHT pressure on LEFT flute edge to force drill into locater. DON'T apply pressure on right flute edge, it will SCREW up the drill. For safety, be sure drill contacts the grinding surface WITHIN rim's width , then sweep drill across rim's full width, being careful not to stray off the rim. Grinding action ceases when wheel sparks out. Wheel will continue to produce light sparks after spark out. True spark out is determined when spark intensity decreases noticeably and grinding sound changes from harsh roar to a softer tone. With spark out, rotate drill to complete the job. However, if drills were ground at XLC thru MC, or you desire photo C & D points, proceed to next grinding procedure. If primary facet (PA) was ground at MC setting, grind secondary facet (SFC) as follows. Select HC setting on the lip clearance scale, follow step 3, back off feed screw and grind while frequently checking progress until PA PB PC PD facet size approximates that In PA and wheel sparks out . Then complete opposite side. If primary facet setting was LC, enlarge SFC SFC to approximate size of white scribed line. If primal facet was XLC, enlarge SFC to approximate size as In PB. PRIMARY FACET NOTE! To save time, SFC can be ground by hand. PC. This self-centerlng point can utilize XLC thru AC primary facets. Same grinding procedures as with Photo A but be sure wheel sparks out before facet dividing line approaches the chisel's midway point. Then back off the feed screw very slightly several times with spark outs after each feed screw adjustment until the facet dividing line reaches the chisel's midway point. Then rotate drill to grind the other side. NOTE: Until practice is acquired, It's best to leave facet dividing line a little short of chisel's midway point since it still results in an effective self-centering point. If the facet line is accidently over extended, RE-INDEX and start over. P D. Secondary Drill Point Angle (SPA). For primary lip clearances that were ground at AC thru HC, align and lock 90 mark of ring scale with SPA and grind until desired size of SPA and spark out is achieved. Then grind other side. For lip clearances ground at XLC thru MC , first complete SFC and RE-SET carriage bed at AC LIP CLEARANCE setting. Then align 90 degree mark with SPA setting. SPA equals 15 to 25 percent of cutting lip's overall length. NOTE: SPA can be ground on all types of points. (See instruction manual for more details)

The following "Special GRINDING PROCEDURES" are a MUST when converting a standard drill to the flat grind, changing point angles, dealing with excessively ground, badly worn, or broken drills.
BROKEN DRILLS: Extend drill beyond drill bed just enough to expose drill to the wheel and grind a little more than halfway through drill's diameter and spark out the wheel. Then, use the indexing gauge to check the newly ground lip and baffle line alignment. If there is alignment, grind the opposite broken side to complete the job. If there is no alignment, RE-INDEX and re-grind the new cutting edge, spark out and complete the second side. NOTE: Even after a drill is correctly re-indexed and re-ground, always double check the lip and line alignment and repeat CORRECTIVE grinding action again if necessary. FOR BADLY WORN, OVER-GROUND or conversion of CONVENTIONAL POINTS to the FLAT GRIND, Index as usual and follow above re-grinding and re-indexing procedures. CHANGING POINT ANGLES: lf changing from blunt to a more spear shaped point, OVER-INDEX with the cutting edge angling up across two baffle lines and follow above re-grinding procedures. When changing from spear-shaped to a more blunt point, UNDER-INDEX 2 lines and use the same re-grinding procedures.
INTERCHANGEABLE ATTACHMENTS
Track and Spade bits are extended beyond drill bed approximately 1/4" for tool exposure to grinding wheel. Note: In P1 and P2 that both hands and fingers SQUEEZES support and drill beds TOGETHER and hands oscillate the attachment across the rim's FULL width. P1-Left thumb is squeezing support and drill beds together and simultaneously pressing down on track bit. Right thumb is pressing tool against wheel and index finger presses shim against bed's vertical wall. P2-Similar technique on spade bits but both Index fingers are pressing on tool and both thumbs are pushing tool towards wheel. P3-Right thumb feeds workpiece to the wheel while index finger and left thumb keeps workpiece against the fence. Both hands work together with remaining fingers gripping table's under surface to sweep workpiece across rim's FULL with. NOTE: Table's front end must be within 1/8" clearance with wheel and controls FIRMLY locked.

HELPFUL HINTS
If a drill doesn't function, it's due to INSUFFICIENT lip clearance resulting from improper indexing; insufficient SECONDARY facet size on drills sharpened with low lip clearances or excessive grinding. Correct grinding begins in the area of the heels and soon as it moves forward to completely resurface the cutting edge, grinding MUST cease IMMEDIATELY Further grinding REDUCES lip clearance accordingly. If excessive grinding occurs, the drill MUST be re-indexed and reground. Inaccuracy results from failure to grind until screw tip engages lower bed; inadequate feed screw thread tension; drill not fully engaged in locater; UNEQUAL or distorted lands: bent drills, flute debris; failure to sweep BOTH drill faces equally across grinding rim's FULL width; Inadequate tightening of lip relief, drill point angle or drill stop lock controls, of failure to raise-shift stop into contact with lower bed. MOST IMPORTANT: With drills, especially large ones, increased heat build up and expansion in grinding the second face results in additional metal removal & inaccuracy. So, a coolant is a MUST. SHORT bodied tapered shank drills tend to rock in the drill bed. This is prevented with short pieces of extruded aluminum angle, under shank's rear against the cube and taped to drill bed. For offset point centers to prevent drill binding in deep soft metals, complete both drill faces and back off feed screw to grind slight additional amount off second face. Do not remove the plastic washer on the feed screw mechanism. To retain its frictional properties, AVOID LUBRICANTS AND KEEP IT CLEAN with soap and water. After wheel dressing, ALWAYS stone the wheel LIGHTLY with dressing stick. It OPENS the wheel and increases grinding action at least 200 percent. Diamond dressing is best for trueing the wheel, but also DULLS the wheel and drastically reduces grinding action. Due to the machine's unlimited drill diameter range and ability to grind a wide range of tools and other metals it is recommended to maintain fine and coarse grit wheels on hand for maximum customer satisfaction For best results, use interchangeable diamond wheel for drills No. 60 through 1/8" diameter, 60 grit for 1/8" through 3/8", 46 grit for 3/8" through 3/4"; and 36 grit for drills above 3/4" diameter.

INSTRUCTIONS FOR GRINDING SPLIT POINTS, DUBBED DRILLS, PUNCHES & DIES
P1 P2 P3 P4 P5
POINT SPLITTING STEP 1. With drill bed in position to wheel's right (P1), position drill so it's point is roughly flush with front end of the bed and flute edge is in contact with the locator. Then LEFT thumb presses drill's left flute lightly to torque drill against locater and RIGHT thumb applies steady forward pressure on cube until cutting edge spirals into the approximate 15 to 20 degree angle from the vertical as shown. STEP 2: Rotate tool post to align desired number with the etched indicator. NOTE: 90 thru 86 on the right half of the ring scale produces greater drilling efficiency accordingly and 90 thru 86 on the left side results in a little less drilling efficiency but more durable points accordingly. STEP 3. a. Adjust feed knob with left hand to put drill in P2 position (P3 is frontal view of P2). Right FIG. B hand accomplishes P4 position (note drill bed's angle to the wheel) and then hold P4 position with LEFT hand while right hand LOCKS vertical scale control and oscillating system in P4 position. b. Bring feed screw tip into Strike Plate contact. c. Unlock swing stop and boss system to permit 1" to 1-1/2" clearance between drill point and wheel and relock swing stop. STEP 4. a. Energize motor. b. Adjust both feed controls SLIGHTLY for light exposure of the drill to the wheel. c. DUPLICATE hand grips of P2 or P5, in accordance with the drill's size. (Note that left thumb presses the LEFT flute to torque drill against locater.) (Thumb pressure also restrains drill in the bed when drill's being notched). d. Press drill assembly lightly against the wheel until wheel sparks out. Then remove drill to examine notch's progress and compare the notch against the following figures. If the notch's apex is in alignment with the chisel's long (line) axis as shown in Fig. A, It indicates that both knob and feed screw settings are correctly adjusted and additional readjustment of BOTH controls will correctly advance the notch towards the dotted line "V" in fig. A. Once wheel sparks out at desired depth (feed screw tip & strike plate contact), grind opposite notch without disturbing the feed control settings. Fig. B is the result of excessive Knob Feed setting. Drill point was moved too much laterally (to the left) into the wheel's rim. As a result, this notch has screwed up the cutting edge and drill must be repointed and then renotched. Excessive feed is avoided by repetitious LIGHT lateral adjustments and frequent inspections. Fig. C shows excessive feed screw adjustment. However, this point is salvageable by completing the other side but first reduce the feed screw setting. The correct setting would have been to the dotted line. in short, make repetitious LIGHT re-adjustments of either or both controls as indicated to keep the notch's apex in alignment with chisel's long axle (Fig. A). For point splitting, there are no substitutes for skill and PRACTICE. The rewards are INCREASED safety and profits. IMPORTANT NOTES. a. Minimum chisel length is .005" for small drills and .012" for large drills. b. As wheel loads up, FREQUENTLY and lightly stone both wheel's face and side rim with NORBIDE dressing stick. (Available from NORTON WHEEL SUPPLIERS). Use diamond dresser ONLY to restore wheel's balance and sharp corner: ALWAYS restore wheel after EVERY diamond dressing. d. MOST IMPORTANT. If a heavy tapered shank causes the drill to rock, place a 1-1/2" long x 5/16" thick piece of angle steel (shim) AGAINST the cube, UNDER the TANG. DUBBED DRILLS utilize the same technique as point splitting but index the cutting edge into a 90 degree vertical angle, plus or minus 4 degrees. PUNCHES & DIES: a. First place a square block gauge in the Punch & Die Bed and square the bed to the wheel, horizontally and vertically. The Anti-shift Stop is used to fine tune vertical squaring and then press the bed against the shift stop when tightening the vertical control. b. Insert tool, apply clamp and rotate Feed Knob to bring tool up to the wheel but DO NOT, repeats, DO NOT make contact with the wheel. c. Energlze motor and SLOWLY rotate Feed Knob with left hand while right hand sweeps tool across full width of the grinding rim. IMPORTANT!! Don't sweep workpiece off the rim's full width until wheel sparks out. IMPORTANT NOTE. A special wheel is required for point splitting and dubbing. When reordering, specify part MA-CHAMP#19SPW or Point Splitting Wheel.
