Planing narrow stock

material coming out of the planer is a requirement, then straight material will have to be
fed into the machine. Subjecting lumber to a straight-line rip will take the wane out of a
board. Place the ripped edge against the right side fence when feeding this ripped mate-
rial through the machine.
Planing narrow stock
The MP280 can process very narrow stock. However, a motion-limiting block is posi-
tioned in the machine between the two tubes that the left side vertical cutter head moves
on. This limiting block is held in place by two bolts that are accessible underneath the
block. Take out the two bolts that hold the upper and lower halves of this block together,
and remove the block.
Replace the motion-limiting block back into the machine when you are not planing narrow
stock, as this block provides additional support to boards as they move through the
machine, and across the width of the cast iron table.
Planing stock thicker than 2 Inches
The planer can mould and plane stock thicker than two inches with the side heads. To
accomplish this two cutter heads must be stacked. When placing these cutter heads in
the machine, be sure to place the cutting knives on the second head halfway between the
two knives on the first cutter head on that spindle.
Spacers can be used to add height to the upper cutter head; however, it is best if there is
some overlap of the knives, especially with straight knives.
Saving a moulding pattern
If you have produced a moulding that you know you will produce in the future, it can be
wise to take some measures before removing the mounted knives. This will ensure that
you can quickly set the machine for making the same moulding again.
1. Save a 0.5 (1.6 ft) long piece of the machined moulding.
2. Keep the spacers you have used together with the knives for the right and the left side
cutter respectively.
3. Note the setting of the height scale of the table and the rotating scale on the height adjust-
ing crank, i.e. exactly note to what height the machine table is set. Also measure the
machined moulding. Note the measurements of the saved piece of moulding.
