Title: Sometimes it's the quick and easy ones......

Sometimes it's the quick and easy ones......that are the most fun  :)

Took a moment today to diamond drag engrave this "W" in our clocks' pendulum for a nice little extra touch.

Happy Holidays to all!

Nice touch Dave.  ;)

Presumably spring loaded but what type of tool did you use please ??

Tweakie.

I echo your comments Happy Holidays to all.

Thanks fellas, and it is actually a tapping guide that I turned into a spring loaded engraver.

I think I actually posted info about it years ago, but will look again for the pics when I get home from work.

Ok, Tweaks, here you go. This is from a post I just did on the Vectric forum as well:

I use a tap guide (for threading) and quite honestly, the hardened pointed/ground end works great for this as well, as I used that at first with other projects I've done. I wanted to set it up for a diamond tip though, so I designed an adapter to fit inside with a small set screw to hold what are called "phonopoint" diamonds (cheap!), which are really used for dressing precision grinding wheels on a surface grinder (what I do for my "day" job). It works fantastic and they make the guides with such a nice slip fit, and hardened materials, so it's a quality unit. I've done over 130 drag engravings with it and it's still a perfect slip fit.

(I see Enco doesn't allow hotlinking anymore so here are the part numbers:)

Phono/Single point Diamond: 388-8860

Tapping Guide: 325-5179

Rendering of the diamond point adapter shown below.

Hope that helps-
Dave

Thanks for the information Dave.

Hey Sam, you must be busy, you haven't been around much, my friend. How goes it?

Going fine I recon Dave. Doing better than I deserve, I guess. I've not really had time to do any personal projects to share with the masses lately. I'm around here every day though, I just lurk in the shadows.

Hi Dave

Looks very nice.

Typically what sort of depth have you achieved and was it done in a single pass?

Thanks Brian

Hi Brian,

Thank you for the kind words. While I haven't actually checked with an indicator, it seems I get about .010" depth with 2 passes in 6061 aluminum and probably about .005-.006" in engravers brass. The pendulum was a bit more as it's very thin, and easily manipulated as it's hollow, not solid. 2 passes are better as the first pass sometimes gives "hair-like" burrs that seem to be eliminated on the second dry run pass.
