Hi all,
In the model I am making, I have to make a 1/8" x 20SWG slot. The text says
to drill a 0.9mm hole, use a piercing saw, then a flat escapement file.
As I don't have a piercing saw (or escapement file), I am looking in the
cromwell catalog. They have a piercing saw and a fret saw. What is the
difference between them? (piercing and fret). Will a fret saw do the same
job?
Also, I understand an escapement file is a small flat file with only one
side and one edge that can cut. I can't see any in the cromwell catalog. My
own needle files are actually too wide for the job. I guess that I could buy
a needle file and grind it so that it will fit (grind one edge and one side)
to make it into flat escapement. However, if you know of the proper tool in
the catalogue, can you let me know?
Thanks.
Best regards,
Dave Colliver.

Dave,
Is this what you are looking for? The best such files are from
Switzerland, and Vallorbe is one of the premier names. Google "Vallorbe
Swiss files" for more suppliers.

As I understand it a "Piercing saw blade" is held via clamps. This
allows the blade to be thread through a hole before clamping in the
frame. A fret saw blade has a pin at each end to allow it to be held
in slots in the saw frame. I would always consider a fret saw to be a
wood working tool and a piercing saw a metal workers tool.
Therefore you need piercing blades. (And a frame)
Re the file. I would just grind down a flat Swiss file to suit.

Both piercing saw blades and fret saw blades are clamped in their frames
although the frames are different, the piercing saw frames are more rigid
than the fret frames.
The saw blades I think you mean that have pegs to hold the blades are
coping saw blades.
