Lie Nielsen 98-99 Planes Review By: I.Ball

Manufacturer: Lie Nielsen

Plane Type: Side Rabbet

Model No: 98 & 99

The Lie Nielsen 98 and 99 side rebate planes, also referred to as the Lie Nielsen 98 and 99 side rabbet planes are a left hand and right hand plane made from stress relieved manganese bronze, each with a polished cherry knob, and a cryogenically treated A2 steel cutter.

These specialist planes are designed to assist cabinet makers in accurately trimming dados, grooves, moulds and similar tasks. These tools are particularly useful when precision fitting is required such as when a dado or groove needs to be widened very slightly in order to precisely house a corresponding part.

It may be the case that a glass shelf or polished shelf is too thick to fit in the corresponding grooves, rather than adjusting / changing the shelves, it is much easier to alter the grooves, for this task the Lie Nielsen 98 and 99 is ideal.

These specialist planes each have a skewed cutter set at a very low angle of 8 degrees. The noses on the 98 and 99’s can be reversed to create a bullnose type plane or the noses can be removed to create a chisel type plane allowing trimming right into a corner of a piece of work such as on a stop groove.

The cutters are set in the plane with their bevel edges facing upwards. The cutters must be kept very sharp to ensure the best results with the bevels set to a 25 degree angle. When sharpening, it is only really the forward cutting edge bevel which needs sharpening.

It is important the tip of the blade doesn’t protrude beyond the skate, if it does protrude, it will need filing back. Care must also be taken when sharpening the blades to ensure the cutting edge of each blade mirrors the plane mouth(s) profile.

Each plane blade is secured with a bronze clamp piece. The clamp is secured / removed by turning the knurled nut located on top of the clamp.

The Lie Nielsen 98 and 99 planes are each equipped with a depth stop. The depth stop fixes to the rear of the plane. The depth stop is secured in the required position with the use of a knurled nut.

When required, the depth stop allows the user to set the depth at which the plane should operate as well as acting a stabiliser when planing.

The Lie Nielsen 98 and 99 planes are made from bronze which over much time will gradually transform from a brass colour to a deep dark browny-green colour; an aging process which is referred to as patina.

If it is preferred for the planes to keep their original bronze look, polish the tool from time-to-time.

What is stress relieved manganese bronze?

Stress relieved manganese bronze is a process which helps ensure the material doesn’t move / warp and as such in terms of the planes it helps ensure the planes remain flat and true.

Did Stanley make 98 and 99 planes?

Yes, the Lie Nielsen 98 and 99 planes are based upon the popular Stanley 98 and 99 plane designs.

What is the difference between the Lie Nielsen 98 / 99 and Stanley 98 / 99 planes?

The Lie Nielsen 98 / 99 and Stanley 98 / 99 planes have many similarities in their design even including their numbering.

The obvious difference are the material used, the Stanley 98 and 99 were made from cast iron with Rosewood knobs whereas the Lie Nielsen planes are made from bronze with cherry knobs.

More subtle differences are the Stanley planes use thumb screws to secure the clamps, and they had a slightly more elaborate design.

Early Stanley 98 and 99 planes also weren’t equipped with depth stops.
