Super 30/30 & Super 30/40
Table Jack-Screw Repair
Strippit Custom 18/30, Custom 30/30, and Custom 30/40 Machines
have Solid Fixed Table-Mounts and their Tables do Not move Up & Down.
Strippit Super 30/30 and Super 30/40 Machines
Do have Adjustable Tables using 4 Chain-Driven Jack-Screws and
Can Move Table Up & Down using a Rotary-Handle at front of Machine.
But. As Nobody Maintains Jack-Screws, oil & greasing, adjust chain, etc.
they tend to fail in old-age. Many Tables are also Damaged by Knuckle-Heads who Bump into Machines with Fork-Lifts, Careless Machine Riggers & Movers,
or Idiots trying to pick-up the Machine with Forks under Table.
As these Machines are now Decades out of production,
Jack-Screw Parts are Not Available, so any Special Parts you need
will have to be Fabricated by yourself or a Good Machine Shop.
As Adjustable Tables are rarely needed or used, you can
Repair by making Solid Table-Mounts to take the place of Jack-Screws
like on a Custom 30/30 or Custom 30/40 Machine.
1 -- Cut & make some Wood Blocks of 4" x 4" or 6" x 6" to Block-Up and
use as Safety-Stands so there is NO Possibility that the
Very Heavy Plate-Steel Table
could Tilt or Fall and Crush someone working underneath Table.
2 -- Put a Scissor-Jack near 1 of the 4 Corner Jack-Screws and Jack-Up that
Corner just enough to take Table Weight off of the Jack-Screw.
Put Wood-Blocks under Table as a Safety-Stand so there is
NO Possibility that Plate-Steel Table could Tilt or Fall and
Crush someone working underneath!
3 -- Unbolt that Corner's Jack-Screw and Slide it out of Machine.
4 -- Make 8 -- 1/4" Steel Plates about 4" x 4" or so, and
Drill bolt-hole pattern on to Steel Plates to
Match Top & Bottom Mounting-Plates of the Old Jack-Screw
to become New End-Plates for New Solid Table-Mounts.
5 -- Cut 4 pieces of Thick-Wall 2" x 2" Steel Square Tubing.
Measure length so that when New End-Plates are
Welded on to Tube-Ends and Installed in place of Jacks-Screws,
the Table would be a slightly lower that a New Die Top.
6 -- Bolt Top & Bottom Plate to Machine & Table,
push-in a 2" x2" Tube, and tack-weld. Remove and finish welding.
Reinstall and Bolt-In this New Solid Mount.
Do All this 1 Corner at a time!
Repeat for the Other 3 Corners.
7 -- When all 4 New Solid Mounts are installed,
Cut & Make and add Steel Shims underneath your 4 Solid Mounts
to bring the Table-Top Up to the
Same Height as the Top of a New Die installed in Machine.
