New  Hook  &  Handle  Repair Kit Can be Installed
with Punch-Ram Assembly on Machine,  But  it is Difficult.  
It is MUCH Easier with Punch-Ram Assembly off of Machine!

Use  Short  Pin-Punch  &  Ball Peen Hammer to Carefully Tap  &  Pound-out
1/8"  Roll-Pins,   I  usually do these from the Top,  driving them Down & Out.
Some Machines you can Punch from the Bottom,  whatever works for you.

Next do  1/4"  Roll-Pins.   I usually do these from the Bottom Pounding them Up & Out.
Use the stout Short Pin-Punch to get it moving,  then switch to longer Pin-Punch.
You do have a Full Set of Short & Long Punches,  don't you?

If you don't have Punches,  you can also use Drill-Rod held with Pliers.
McMaster-Carr  #8893K147
Cut-Down to  3-inch long   .120" Drill-Rod to punch-out  1/8" Roll-Pins.
McMaster-Carr  #8893K201
Cut-Down to  3-inch long   .242" Drill-Rod to punch-out  1/4" Roll-Pins.

After 2  Roll-Pins are Tapped-Out on each side,  you should be able to Slide-Out the
Hook and Handle  Assembly on each side of Punch-Head.

Keep  Left  &  Right  Hooks  and  Left  &  Right  Handles  Carefully  Separated
so that you do Not become Confused when Reassembling!!!

Remove the Old Hooks from Handles.

Remove hold-down Screw and remove Old Cams from Handle Assembly.

Fit a New Cam onto Handle,  put a Drop of Loc-Tite on Screw Threads, 
and carefully install Screw into Cam.

Coat Cam Lightly with Grease
Very Carefully Tap Correct-Hook into
Correct-Handle with a Plastic-Hammer so that Cams are Not Damaged!
  Cams will fit Very Tight into Handles!

Slide Completed Hook & Cam Assembly back into Punch-Head.
When you slide Hook & Handles back into Head, 
use the  Solid-End  of a  15/64" Drill-Bit  to
Center  &  Line-Up  Cam-Hole  with  1/4" Head-Hole for the 1/4" Roll-Pin.

You will need to hold on to Drill Bit with a Rag because
as you pound-in the Dowel-Pin from other side,
the Drill Bit will fly-out  and  you will lose the Needed Alignment!

If  Cam  &  Handle  &  Roll-Pin  are  Not All Lined-Up Perfectly
you will  Mangle  &  Damage  New-Cam  And the  Thin-End of Handle
when you Pound the Roll-Pin back in!

I usually Grind a Small 45-Degree Bevel on to 1/4" Roll-Pin Ends on my Belt-Sander
to help start Roll-Pins going through the Holes.
If the Beveled End gets damaged,  you may want to Re-Grind Bevel.

Tap 1/8" Roll-Pin in from Bottom,
it Only needs to stick-up  1/8" into  Hook-Groove,
any more will only make it break-off sooner.

When,   not if,   1/8" Roll-Pin Tip Breaks-Off again someday,  
just tap-it up another  1/8" into groove again.
This can be done several times before you would need a new pin.
Extra Pins are Included in our Kit.

Grease everything,   and  Keep it Greased,
with a good  Synthetic Black-Moly Grease   to keep parts from wearing.

Installing  Hook and Handle Repair Kit

The Following is NOT Complete Step by Step Instructions.
If you Need Detailed Instructions and do Not have Proper Tools,
perhaps you should Call a Experienced Serviceman instead.
Starting about 1960,  the Strippit Company Up-Graded their  Single-Station Punch Machines,  such as  Sonic 15,  Custom 18/30,  Super 30/30,  &  Super 30/40,  using their New-Style Swing-Arm Punch-Holder.   These Swing-Arm Punch-Holders used Strippit's  New,  at that time,  Hook & Handle System to Lock Punch-Holders to Machine.

Hooks & Handles  do Lock-In Holders well when New.

But,  eventually they accumulate Wear,  Especially because
Operators  Never  Lubricate  them  with  Grease!  
This Wear allows Swing-Arm Holder to  Move & Deflect  under Punch-Loading, 
causing  Poor Tool Alignment,  Poor Punched-Hole Quality, 
and  Much  Punch & Die Wear.

As  Hook & Handle  and  Lock-Pin  Wear gets worse, 
Handles will Not even stay locked-in causing
Handle-Lock Limit-Switch to  Not-Close,   and  the Machine Stops Punching.
Solutions is our   Hook  &  Handle  Repair Kit.

The Correct Way to Repair would be to
Replace  Left  &  Right  Hooks,
Replace  Cams  on  Left  &  Right  Handles, 
Replace  Lock-Pins  on your  2  Swing-Arm Holders.

The Rocket-Scientists  at some Shops put
Bungee-Cords on Handles to keep them closed,
as if  Rubber Bungee-Cords would
Hold  Tool-Alignment  on a  30-Ton Punching Machine!!!
Very Stupid.

Then these Same Rocket-Scientists
try a bit of Weld on Hooks  or  add Shims to
Force  Hooks & Handles  to  Lock-Up.
The Rocket-Scientists  are  Surprised
when  Hooks & Handles  Break  into  NON-Repairable  Pieces!

Now they have a  Real Problem 
Handles are a  Precision Assembly  that are
NO Longer Made   or  Available  Anywhere!
Don't Even Think Of Trying That!

Handle-Lock Limit-Switch is located behind the
Punch-Head Housing Assembly.

If Handles do Not Lock-Up properly to Close this Switch,
Machine Will Not Punch.

When dropping-down this Punch-Head Housing Assembly
be Very Careful that you do NOT Damage these Parts!

I have some  Switch  &  Spring  Parts,
But  Other Parts like  2 Rods,  Barrel,  Bracket,  Etc.,
are Very Hard to get   or  just  NOT  Available!!!
Photo above is a  Strippit  Super 30/30  Punch Machine
with   3 1/2" Swing-Arm Punch Holder,   1 1/4" Swing-Arm Punch Holder,
and a    3 1/2"  to  1 1/4"  Die Adaptor.
We now have  In-Stock a 
Very Limited Supply  of
New  Hook & Handle  Rebuild  Kits.

When they Sell-Out, 
we are Not going to make more Kits,
so if you Need to Rebuild Yours,
Don't Wait Too Long!

1 Set of Lock-Pins come in the Rebuild Kit, 
for  1 Swing-Arm Holder.

Order a  2nd Set  of Lock-Pins
for your 
2nd  Swing-Arm Holder!
First,  if you don't already have them,  acquire
a Good Set of Pin-Punches.   Here is a set of 4
that I bought from the  Mcmaster-Carr Co.

1/8"  Short Pin-Punch   #3416A13

1/8"  Long Pin-Punch   #3416A24

1/4"  Short Pin-Punch   #3416A31

1/4"  Long Pin-Punch    #3416A4
To rebuild Hooks & Handles,  Punch-head does Not have to be dropped-down off Machine.  But,
There is very little room to work-on Punch-Head Assembly when it is on Machine.   Which is why
we have to  Make Very Short Pin-Punches.

So using a Abrasive Cut-Off Saw 
and a Belt-Sander to Dress the Ends,
Cut-Down  the  Pin-End 
on Long Punches to about  2 1/4", 
and I also
Cut-Down  Handle-End,  the  Shorter-The-Better
to also give me  More Hammering Room.

I also Very Lightly Dress the Sides of Pins with
Belt-Sander so that Pin is slightly Undersize
and then will have Clearance to easily go into
the Drilled Roll-Pin Holes.

When using,
you can hold Very Short Punches with Plyers.

And use a good set of 
Brass  Hammers.

Don't be an
and try to use a

Pull-Out the 2 Old Lock-Pins
from your
1 1/4"  Swing-Arm Holder
Throw them Away!

Lightly Oil
2 New Lock-Pins
from the Kit and
Insert them into Swing-Arm Holder.

Keep Pins Oiled to Reduce Wear.

1 Set of Lock-Pins come
in the Rebuild Kit,

Order a  2nd Set of Lock-Pins
for your Other
3 1/2"  Swing-Arm  Holder.

If you are Dropping-Down
the Punch-Head for Any Reason
Replace the  Packing Rings
and  Ram-Springs  using the
Punch-Head Rebuild Kit!

And,  if you have the
Punch-Head  Dropped-Down
for whatever reason,
it's  Very  EASY  to Install 
Hook & Handle Repair Kit
with the  Head-Down.

Note,   be Very Careful
when pulling
2 Specially-Made
Tapered Dowel Pins
that Locate Punch-Head. 

Special Tapered Dowels Pins
are No Longer Manufactured
so do  NOT  Bugger them up!
Use a Dowel-Puller to pull them!

Using a  5/16" Bolt  S.H.C.S.
Threaded into Dowel-Pin,
Tap Dowel Carefully
Back in place with a
Brass-Rod  &  Hammer.

There Really Are Monsters
Under Our Bed.....
Punch-Head Rebuild Kit!
And a Word  to The Wise.

I would Build a Strong-Rack  with  2  Good Wood-Holders/Boxes
for my  2  Swing-Arm Holders,   Right Next to my Machine,
Because Your
Knuckel-Head  Operators
will leave the Other Swing-Arm Holder, that they are not using,
Sitting-Out on Machine Table,
and sooner or later,   Will Knock it off Table
Cast-Iron  Swing-Arm Holder  will 
Split-In-Two  when  it Hits the Floor!

Broken  Swing-Arm Holders  Can  NOT  Be  Repaired!

Swing-Arm Holders are  NOT  Manufactured anymore so you  Can't Replace it!
Above  Diagram  and  Bill of Materials  is for Reference only.
Many of these Parts are No Longer Available.
