I have always used a .5" 60 deg. CMT Laser Point bit and run it at .5"/sec. feed and .5"/sec. plunge. And then run it again at the same settings. But, as I said, it is a nice plaque and looks pretty good as is....joe

If lightly done then allowed to dry it might just hold those 'chips' in place. Second suggestion what if you used a 1/16th tapered ball nose instead of a v bit? Just thinking out loud! I like the job so far. Russ

Thanks Randy. SOME parts of the inlay clearly broke off, probably while carving it, but were hard to detect somehow. However, the gap around the border of some of the inlay but not other parts leads me to wonder if something else is wrong...
I'm curious why the recommendation on the 30 degree bit? You think a narrower-angle bit will work better for the inlay vs a wider 90 degree bit ? Is it that it's less likely to take off too much out of a soft wood? I would think the steeper angles it puts in would leave it more vulnerable to the inlay chipping out little bits...
Why would grain orientation matter (other than aesthetics) ?

...is the V-bit I use for inlays and even letter engraving. Once I started using it (from the 60-degree bit I was using), my inlays (and I've done hundreds) were consistently better, particularly those with a lot of fine detail. I was having far less tearout, much cleaner cuts. Maybe my 60-degree bit was dull.
As for grain orientation...well...I suppose it has been ingrained (pardon the pun) in me for so long to align grain, it's just something that stood out. Wood expands the same way along the grain, but these pieces are so small, expansion wouldn't be a problem...so...yeah...just looks better.

It doesn't take much for a large bit in a small space to chip out some lettering. As far as the inlay, I never saw the u tube version, I would tell you to read the one in the v carve category that is pinned toward the top. You shouldn't have gaps except where they may be tear outs, but with the way they go together there should be a gap between the inlay and the female pocket that would be part of the engraving, and eliminate the tear out.

The PDF has been used by lots of forum members, some just as it is written & some by making small changes which are mostly mentioned somewhere within that thread.
