4 -- I Wash Die-Base to get every Bit of Dirt, Grease, and Metal Bits off of it. Then run a Flat-File over Bottom of Base to Remove All Burrs from Original Doweling Process. Clean it again if necessary. Bottom of Base should now be Perfectly Flat and Clean.
5 -- On 1 1/4 Inch Bases, make sure Top-Cap on the back #83639-000 Location Pin is Not Broken, Press it out and replace if necessary.
6 -- On 3 1/2 Inch Bases, make sure Top-Cap on each side #87245-000 Location Pin is Not Broken, Press it out and replace if necessary.
7 -- On 3 1/2 Inch Bases, using a thin hand-punch, punch-out the 1/4 Inch Die Location Dowel Pin at back of Base, and carefully tap-in a New 1/4" x 1 inch Pin.
8 -- Now do same Cleaning Process to Lower Turret where the Base is Mounted. Remove all Dirt, Grease, and Metal Bits. Wash with solvent. Flat-File Turret to Remove Burrs. Wash again. Mounting Position should be Perfectly Flat and Clean.
Also Clean-Out 4 Screw Holes in the Turret.
9 -- Clean the 4 Mounting Screws, or Replace them if Damaged.
Put a little Loctite Type 242 Thread Locker on Screw Threads.
10 -- Put Die-Base back in Turret, and reinstall the 4 Screws. Run Screws down until they Touch Base and start to get Tight. Then Back Off 4 Screws about 1/3 of a Turn. You should now be able to Move Base, Smoothly, in Any Direction about .030" which will allow us to achieve Alignment.
11 -- Put your Alignment Die in the Die-Holder, and install it in Die-Base.
Put your Cardboard Separator over Die. Put Alignment Tool in Upper Turret.
12 -- Rotate Turret, By Hand, until this Station is Under Ram. Fire Shotpins In.
13 -- Hop-Up on Table and lay on your Belly again. Support Upper Tool with a Couple of Fingers, pull-out the Separator, and Lower Tool. Again, When my Tools will Not Mate from Miss-Alignment, with the Light-Pattern I can Easily see Problem.
There is Bright "Light" on Side of Punch & Die
where it is "Loose" with Too-Much Clearance.
And it is "Dark" on Opposite Side of Punch & Die where they are
Overlapping & Hitting with Too-Little Die Clearance, which Stops the Light.
Move Die Base Forward & Backward, Left & Right, Until Tool will Fall-In to Die.
Raise and Lower Tool Several Times Until Tool will Fall-In With-Out Touching Sides of Die at all. This is Perfect Alignment, and you can Achieve this if you do these Steps Carefully, and at this Point, you should settle for Nothing Less than Perfect Alignment!
Carefully Tighten 2 Front Die-Base Hold-Down Screws. Check Alignment again.
If still OK, Pull Tool out of Die, Put your Separator back in, Fire Shotpins Out, and Rotate Turret back to Load-Station.
14 -- Tighten the 2 Lower Screws underneath Turret. Make sure all 4 Screws are Tight, but be Careful you do Not Strip-Out Threads in Turret, as Turret is fairly Soft Cast Iron.
Do NOT Put Dowel Pins back in Turret!
This will Move Die-Base and Lose Alignment if you do put them back-in!
Dowel Pins are NOT Needed and you will Never again use Pins on This Station!
You should now Rotate Turret back Under Ram and Recheck your Alignment Work.
If you have done this Alignment Process Carefully, you should now have
Perfect Alignment on This Station. If not, Repeat Alignment Procedures until you do!
There are Other Factors that can cause Odd Alignment Problems, Such As;
--- Worn Striker-Plate on the Bottom of Punch-Ram can "Kick" Tools when Punching.
Striker-Plate can be Removed, Measure it's Thickness, Surface Grind it Flat,
make Shims to put under Plate to Shim it back to original Thickness, reinstall plate.
--- Old Worn Punch Tool-Holders can be Loose in Turret Bushing and will Move & "Tilt"
when Punching. Throw-Out Your Decades-Old Holders, and Buy NEW Holders!
--- Worn or Damaged Die-Holders can allow Dies to Move around while Punching,
repair or replace as needed.
--- Worn or Damaged Die-Bases can allow Dies to Tilt or Move,
repair or replace as needed.
If you Really Want Good Alignment, Correct All of these Problems!!!
Also, Never, Never, Dry-Punch Machine With-Out Sheetmetal!!!
Lets say you are using .008" dies, which means that there is Only .004" Clearance on each side of Die if Machine & Tooling were Manufactured Perfect, which they are Not.
So if you Dry-Punch with No Sheetmetal in Machine, Even 1 Time, you can Nick & Ruin a Tool on the Very First Punch! It is a Little-Known Fact that when you have Metal in Machine, there is a Self-Centering Action as the Punch goes through metal that moves the Punch-Tip to Center of Die that Helps Prevent this "Nicking" and Dulling of Tools from happening even when there is Not Perfect Alignment. Never Dry Punch!
And Of Course,
These Alignment Techniques can be used on Any Turret Machine, not just Strippits.
