Super strong CNC inlays reinforced with epoxy

[@markeverett1393]

Clear, cogent descriptions made this tutorial a delight. I especially appreciate the embedded picture of the bit with its case; I wish more CNC videographers would include this simple expedient. Very nice!

[@eitantal726]

PSA: Tapping with a hammer (17:28) is a critical step. You can see the piece shifting down. I did not do that & paid dearly. So is clamping at the entire perimeter, against the piece itself, with multiple clamps.

[@stephanforseilles]

There is no such thing as "too many clamps." ;)

[@michaelmunch8682]

Had an idea after watching this. You could do all your inlays then machine a pocket in the backside to the correct depth then backfill with epoxy and cap it with small inlay on the back.

[@saintb6969]

I have been doing this for years now (Inlay Cutting Boards and using epoxy to support the plug), But I give you awesome credit for taking the time to show and tell others how to do it. Unlike others who think they are going to give away a super secret or ones like myself simply because I am just not into making video One thing I can suggest is try some of the 5 min epoxy it will speed up your timeline, and also watch the epoxy on some end grains that are porous as the grains are like an open straw and the epoxy will sometimes seep to the other side, hence another reason to use the fast cure epoxy. Again awesome job.

[@stephanforseilles]

Have you ever tried to use epoxy instead of wood glue? I didn't want the epoxy to come in contact with the food, that's why I did it in two steps, but I was wondering.

[@saintb6969]

@@stephanforseilles no, like you I do not want the epoxy to be near the food. On decorative boards I have done I have used epoxy inlays on the back side where I knew food was not going to come in contact with it.

2:00 "Flattening takes 40 minutes" What are your thoughts on a flattening bit? Is it not suitable for end-grain?

Hi Stephen The islands you can specify the depths of the inlay In preparing the female for the placement of the male? (Mmm) I have a small problem that there is no perfect match and there are no spaces left in the intermediate placement Thanks

Hello. I generally leave a 1mm glue gap between. Typical would be: -9mm depth for female -8mm 'insertion' -2mm above surface to be cleaned up

Howdy, I am very interested in the vcarve technique you used to allow for the lettering "Harley Davidson" to be raised letters in the recess, and the mating plug that has the cutouts for those letters. Do you have a video illustrating that technique perchance? Or where I might see such in action? Thanks, Bill

[@stephanforseilles]

Hello. I use the same technique that I explain in this tutorial: kzbin.info/www/bejne/iIqTq3-saNyWr8U , just varying the depth so each inlay sits fully into the one below.

@@stephanforseilles Thank you, I will check it out!

[@unclebob8746]

Excellent work and video! Can you publish some guidelines you use for depth of female socket and height of male plug based upon the general width of the inlay please. A dust shoe would be a great addition to your CNC when not making videos....

[@stephanforseilles]

Thanks! I generally go for 8 to 10mm depth for the large pockets and a 1 to 0.5mm glue gap. For smaller inlays, it's 5mm with no glue gap. But I adapt the depth so that every part of the design 'bottoms out'. I do have a very functional dust shoe but I always remove it when filming because I think the "bit close-up" shots are mesmerising. :)

[@michaelkeymont501]

I always thought I’d add a dust shoe to my machines, but both are air-cooled spindles so they blow the chips out of the way automagically. I built enclosures around the machines and just vacuum up when the job is done... or every couple of weeks, depending on how lazy I’m being. I use dry lube for everything and the sawdust just falls right off.

[@BrianWilliamsInspires]

Why not use a larger bit for the flattening?

[@stephanforseilles]

I've tried 12 and 16mm 'flat inserts' bits but in end-grain hardwood those vibrate a lot if you don't have an industrial-grade machine, and I have to slow down the feed/speed so all in all, I don't gain much time.

[@Chappy_V]

you can significantly turn up your feeds and speeds, as in the first pocketing cut you had lots of dust instead of chips... i think you could stand to run your machine a bit faster. Really enjoyed the vid and love the end result

[@stephanforseilles]

Since this video I indeed lowered the depth but dramatically increased the speeds. My usual f/s for 6mm bit in hard wood is 4mm @ 1000mm/m.

[@Chappy_V]

@@stephanforseilles im an imperial baby so idk what that translates to exactly but that does seem more adequate for the job at hand

Around 20mm.

Regarding food safe finishes I bought some cutting board oil on Amazon (250ml for €16 + delivery). After some research I went to the chemist and bought 500ml of liquid paraffin for €9.50. The 2 products are identical !

[@stephanforseilles]

Indeed it seems to be basically the same thing!

[@jamesofcork]

I am just a beginner to CNC but why don't you use a larger cutter for the levelling the workpiece ? Thanks

[@stephanforseilles]

Because I'd have to lower drastically the RPM with such a cutter and then the feed rate would become really really slow.

[@jamesofcork]

@@stephanforseilles OK thanks

[@alexanderarvidsson1041]

I've pored over all of your videos, and I'll echo everyone else: they are fantastic and very educational. But I have a question if I may. I've had great success with the Zank inlay technique with V-bits at or above 30 degrees of angle. Like you, I decided to look at alternatives and found both the spiral tapered ball nose bits, as well as the Huhao engraving bits. But - I can't for the life of me get the "classic" Zank math of "depth of cut = reach into the pocket and flat depth = length sticking out" to work with any bits set as engraving bits. I've checked and rechecked the angles, but at the end of the day I'm left with a table of known depths that an inlay will stick into the pocket at any given depth of cut. Have you had to modify the Zank math in any way when using an engraving bit, or is something extremely odd with my Shapeoko? Again, thank you for all your videos!

[@stephanforseilles]

Thanks for the nice feedback! I agree with you: the Zank technique does not work very well with sharp bits (

It seems like you could win a bunch of time back by increasing your plunge rate, especially with the v-bit. Have you tried?

[@sindresolhaug7681]

Hello! I must say you have a wonderful channel and a nice way of showing how to do this without all the extra music and effects of other channels, which I appreciate greatly. I have two questions, if you feel like answering them of course. My first question is, can a CNC like this handle a broader bit for the finalizing passes, so that you do not have to use a 6 mm bit but maybe something like 10 or 12 mm to do the flattening with a small overlap, or would the torque simply become to great for the spindle motor and make it burn out? And second, have you ever tried using the sawdust as a filler material for double/triple pass carvings? I see you use quite a lot of solid wood of course, but what are your thoughts on using a sawdust and epoxy/glue filler, and do you think it would work with multiple pass inlays like this, or would it possibly crumble and become torn out easily as opposed to solid wood? It seems to me that the epoxy in this takes well to being carved by bits like these, but I have no first hand experience with it sadly. As someone with way too many craft hobbies and therefore a limited budget for each one in addition to a small wish to reuse leftover materials and such, I feel that if I could sweep up the dust and and repurpose it into a sort of filler, that would probably cut back on the need to get more materials for each project, especially for the more expensive wood types, as it seems like sawdust is quite abundant after carving on these machines. It would perhaps give an interesting contrast in texture too, maybe. In any case, thank you for this wonderful content!

[@stephanforseilles]

Hello, Thanks for the feedback. I have larger bits for surfacing (12mm) but for end grain of hard wood I find 6mm the 'sweet spot' in terms of speed, rpm (you can't spin a 12mm with inserts at 25.000rpm) and effort on my machine. And cost also, as I use very cheap 6mm flat ends for this. But definitely a larger one might work on a stiffer CNC! Sometimes I fill with epoxy like in this video: kzbin.info/www/bejne/lWTRo4xsfdmLfZI . I've tried mixing epoxy with sawdust but the result was not good at all. :) The epoxy became very thick very quickly and didn't flow in all the gaps. So I use either hard wood or tinted epoxy but I don't mix epoxy and saw dust anymore. Maybe it's because of the brand of epoxy I use... Let me know if it works for you!

[@domthemom2270]

Would using epoxy as the wood glue for the first inlay do the trick?

[@stephanforseilles]

I always try not to put epoxy where it could get in direct contact with the food (on the sides of the inly in that case). But maybe I'm over cautions... ALso epoxy tends to 'stain' the wood in a way that you cannot sand away, as it is more penetrating than glue.

[@michaelchesney3785]

Did you use the same start and flat depths for everything? Do you vary them based on size of the inlay?

[@stephanforseilles]

No, you have to vary them in a certain way. I made a tutorial about it: kzbin.info/www/bejne/iIqTq3-saNyWr8U

[@eitantal726]

On your "Motorcycles" part, you effectively have a zero glue gap, correct? You drilled to the exact amount. If you can do this for part 2, why can't you do this for part 1? You wouldn't need the epoxy then. On my attempt, I left a glue gap of 0.6mm. Small enough to effectively become a glue joint

The gap problem mostly arises when you have both large and intricate designs in the same inlay, here the walnut base (very large) with the "HARLEY-DAVIDSON" words (more intricate). For the second inly ("Motor" and "Cicle") everything is about the same width so the gap is easier to manage.

Hello, the main difference with an X-Carve is that the Aureus uses a specific carving spindle from AMB Kress (1050w) which has, indeed, a bit more torque than the Makita router. It is also a bit stronger in Y as it uses ballscrews instead of belts. Those were the main reasons why I went for this one. But I think that X-Carve now has an upgraded model with ballscrews, not sure... I'd say that for the X-Carve you probably have to lower the speed by 20-30% For reference here are my usual speeds which I adapt a bit depending on the wood, age of the bit, etc: -6mm flat: 1.5mm @ 1200mm/min, 5mm @ 200mm/min (and very low plunge speed, around 100mm/min) -3/175mm flat (1/8): 5mm @ 300mm/min -10° 6mm: 5mm @ 400 to 500mm/min
