| SEAL CUTTERS | |
| These
cutters are made to order and can be made in sets. For
instance,
a set to suit all Onoto top corks and bottom seals would include one
2.0 mm inner cutter and a top cork cutter of 6.0 mm
together with an additional set of six cutters ranging in size from 8.0
mm to 10.3 mm for the plunger seal (according to model). Full
sets are available but most prefer three cutters being 2.0 mmm internal
diameter, 6.00 mm external diameter (cork outer diameter) and 8.3 mm
external diameter (plunger seal) for most Onoto 1000, 2000 and 3000
series pens. The seal cutters are perfectly concentric - the smaller sizes being a snug fit inside the tubes of the larger sizes. The cutters are made from mild steel, sharpened and hardened. Importantly, no matter how often the cutters are re-sharpened, the diameter of the cut seal will never change. We also manufacture seal cutters to order for many other pens. One of the popular requests we receive are cutters for Sheaffer seals for many different models. | |
| Price | $80 AUD + GST for 2.0 mm , 6.0 mm and 8.3 mm diameter cutters to suit most Onotos. Prices for other sizes and quantities are available on inquiry. |

| ONOTO PLUNGER RODS | |
| Plunger
rods for Onotos wear out, break, bubble, burst and bend. The
answer - replacement rods made of brass. These brass rods feature a
cupped plunger backing integrally turned into the bell shaped,
adjustable lower stopper. The rods suit all six different types of
Onoto rod used in nine different Onoto models. They can be
easily
cut to length. The rods are supplied with plunger backing, copper pins
and lock nuts. Original threads on Onoto plunger rods are left hand 5BA threads. WE SUPPLY TWO VERSIONS OF THESE RODS: 1. Rods using the original 5BA left hand threads which suit original thread configurations. These require no further work or mechanical input save for insertion of the original or replacement copper pins in both the plunger knob and the shut-off mechanism; or 2. A version which does not use original thread configurations and instead, uses 3.0 mm metric right hand threads and a combination of lock nuts and pins to ensure that once adjusted and installed, the rod (and its fittings) will never move. Unless you have the mechanical ability to re-thread the plunger knob (from LH 5BA thread to 3.0 mm metric right hand thread), we strongly recommend that you leave the fitting of these rods to ourselves. Ideally, our system of fixing the position of Onoto rods requires the drilling of two 1.0 mm holes to fit copper pins in the plunger backing and the plunger knob. The use of pins ensures that the restoration can be dismantled if servicing is required at a later date. Otherwise, for those who prefer the non-purist method, the plunger backing and knob can be glued into place but obviously, this is irreversible and will (in our humble view), ruin the integrity of the pen. This version of rod suits pens where the knob or other parts (which depend on the existence of good, left hand threads), are damaged. | |
