Saya (scabbard) clamps in ABS...and v-carving...

Postby jblakey » Mon Mar 05, 2012 10:07 am

Hi Guys,

cut some clamps from ABS last night to secure my katana saya (scabbard) for engraving. The saya has a bit of an egg-shaped profile, so it's a bit tricky to clamp. Used a contour gauge to get the profile. Thought about how to attach a bit of padding (so as not to mark up the paint), and came up with a thin coat of silicone caulking - nice and soft, and should provide a nice grip as well. Gave the ABS a little bit of sanding before applying the caulk to help adhesion.

Thanks,
jason

Used my new saya clamps last night to do a test engraving last night... spotted three problems right away...

1. One layer of masking tape is not enough to fully protect the paint on the saya during probing. Will try two.
2. I can see errors during the cut over the most curved part of the work surface. GASJ's interpolation is planer, so this was probably to be expected. Will try upping the probe resolution to 1/64 of an inch to see if the output is acceptable.
3. There was some kind of clear coat or lacquer finish over the paint on the saya that slightly peeled/chipped during the cut. No idea how to fix this one.

Thanks,
jason

Oh, forgot to include the pics showing the deformation of the z-axis with GADJ. You can see how it follows (mostly) the contours of the curve.


Thanks,
