Project post-mortem...
I tried my first inlay this weekend and the result was less than spectacular.
Attached are the pictures of the results and the .crv files I used to create the parts. Can someone clue me into to what I did wrong? The inlay doesn't fit correctly in the v-carved pocket and I'm stumped as to why.
The material used was mahogany and poplar. The pine just disintegrated under the v-bit.
Thanks!

your inlay was cut with pockets and not vcarved. Plus you need a start depth and finish depth when doing inlay. I use .125 as the cut is .25 when done.
to save time create boarders around the letters and saw blade so you don't have to remove all of that wood it will save a lot of time. also it will be easier to glue up the separate pieces. You want a lot of glue and as much clamp pressure as possible to get perfect inlays.

Gene,
The .crv file seems to contain only the "socket" for the inlay and not the inlay itself.
With a socket flat depth of 0.2" the inlay should be cut with a start depth (D) of something like 0.1" and a flat depth (D) of something like 0.1".
The key to this type of inlay is that the sides of the cuts get forced together. The inlay and the bottom of the "socket" should not touch. Forcing the sides together is the reason for a lot of clamp pressure. Use lots of glue and let the glue set completely before removing the inlay backing.
Some materials leave a lot of "fuzzies" that need to be cleaned off before the inlay will fit tightly. If I see "fuzzies", I usually make a second pass on the cut. If there are still fuzzies, I use a wire brush to get them off.
It also looks like the cutter tore the inlay while being cut. You need to change the cutter, the cutting parameters, or the material to get a better cut.
I have experienced one other issue that might be at play here. Sometimes cutting the socket or inlay will release some of the stress built up in the wood. This can distort either piece and you want the final pieces to fit with extreme accuracy. A strategy in this case would be to cut both the socket and inlay in two passes with the first pass being perhaps 0.030" high.
Keep us posted.

PS I like the design!

If v-carving would let me carve the outside outline of the lettering instead of the inside, you'd be correct. However, I just changed the pocketing to v-carving and sure enough, it v-carved the lettering into the material, rendering it useless as an inlay.knighttoolworks wrote:your inlay was cut with pockets and not vcarved.

I've attached an image of what the panel looks like when carved with my original file.

Paul the zip file contains the inlay portion. It was too large uncompressed to upload to the forum.Paul Z wrote:Gene,

The inlay was cut using a start depth of 0 and a cut depth of .25. The base material was cut with a start depth of zero and a flat depth of .02.Paul Z wrote: With a socket flat depth of 0.2" the inlay should be cut with a start depth (D) of something like 0.1" and a flat depth (D) of something like 0.1".
I don't know how you guys are v-carving the inlay and still getting a "raised" letter.
Thanks. It's a year-late xmas present for the old man.Paul Z wrote: PS I like the design!

I'm obviously missing something, so I'll keep trying.
