I have already had my share of playing with all these but my first time to actually use a jeweler's saw. We typically use a scroll saw for cutting, but hadn't had a WHOLE lot of luck with it...Today, I think I figured out WHY -- not enough teeth per inch for the gauge of metal we are cutting! So, that will be the next experiment for using the scroll saw.Come to find out, there is a standard table to determine how many TPI (Teeth Per Inch) your blade needs to be based on the gauge of sheet you intend on using it on. To have a proper TPI - Sheet Gauge ratio, you must have at least 3 teeth on the metal surface at all times. If memory serves me, the table goes something like this:
28ga -- #4/0
26ga -- #3/0
24ga -- #2/0
22ga -- #1/0
20ga -- #1
18ga -- #2
16ga -- #3
14ga -- #4
...and so on in both directions up and down the table. The smallest I have noticed so far is 8/0 (TINY TINY TEETH for some super thin sheet!!!).
David seemed to thoroughly enjoy himself! He blew right on through to make THREE different types of soldering applications! The instructor was smiling knowing he was so eager to learn!
We are really anxious to see what next week holds. I am already imagining actually being able to MAKE pieces I've had locked inside my head!
