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.
