New points for fine detailed work
Introduced July 2003
New PP51 and PP52 points
Made from a new flat section alloy which is strong and rigid.
The tip radius
is equivalent to that of a fine 26 SWG point (PP10) so it will do the same thickness
of line.
The advantages over the old "fine" 26 SWG round wire points are as
follows.
- The heavier section metal does not bend or flex so much in use, giving
better control.
- The temperature is more stable and does not reduce so suddenly when the
tip touches wood.
- It will run much cooler at the low heat setting - ideal for leather work
or slow fine detailed work.
- If the point (PP51 only) is turned through 90° it will do a wider line
or could be used for shading effects.
- PP52 is dual purpose - one side for fine lines or - just flip over for shading
- The tip can easily be modified by rubbing on an abrasive block to give
a bigger tip radius to suit your needs.
- The flat section wire is much easier to squeeze up with pliers when you
make your own points
- The flat section can be easily "rolled up" to make effective "solid"
points for shading
- The new alloy is a higher electrical resistance so it takes less current
and is kinder to your machine.
More about the PP52 points
The dual purpose PP52 point is the same as the PP51 but with one side ground away
a little at an angle. This gives a better view of the fine tip as you work. It
can be polished by rubbing on a sharpening stone to give a rounded surface. The
rounded surface is good for shading effects - just flip the point over for shading
or broader lines.
We do not stock the PP52 because, to get the angle of the little facet right for you, it is best if you do it yourself by buying (or making) PP51 and rubbing it
on abrasive to suit the angle you normally work at. This is shown below and only
takes a few seconds on a stone.
Prices (correct March 2009)
PP51 point £2.20 for pack of five
2metre flattened 23 SWG wire (in the new alloy) for making your own points £2.20
Shaping and polishing stones
These are the same as an "oilstone" used to sharpen chisels, perfect for shaping, polishing and cleaning pyrography points to keep
them in peak condition. Double sided ones are best - coarse one side for shaping and fine
the other side for polishing. If you do not have one of these you can use some fine abrasive paper or cloth stuck down to a block with double sided tape.
We are always happy to help users develop new points and new applications for
the machine. If in doubt please ask!
