Yes*, but you will have dark glue lines.
Make sure you have good ventilation as the fumes are quite strong, especially the hardener. I'd also recommend using the fast hardener H60F in cold weather, I've had the slow hardener (H60S) literally take days to set in winter.
Also, mix the product on a flat surface. DO NOT use a cup or other small container as the reaction in the glue produces enough heat to potentially self-ignite (or at least smoke and smoulder) if there isn't enough surface area to dissipate the heat. If you have any mixed glue left over, spread it out on the mixing board and let it set; I found out the hard way that making a neat pile of it is quite a bad idea.
*For incidental contact on a board there should be no issue, but if it was for a storage container where the food will be in contact for a long time you might want to look at something that is certified.
Just use titebond 11 absolutely no need for fancy stuff
Thankyou for that excellent information Elanjacobs. Most helpful indeed.
Concise and accurate advice is hard to come by I often find. Especially timely.
China, I have fancy techniglue in my shed. Titebond is 500 km away in city. I have that desire to be making this board now. My average woodworking skills and equipment could probably do with the gap filling properties of techniglue also.
.
I was requested to make it 16 mm thick which I suspect is too thin for great strength in an end grain board so maybe the techniglue might help there as well. The timber is jarrah and another Aussie hardwood which is hard as a cats head. Not sure of it’s type but it is straight grained, a light sandy fawn type colour, cuts sort of sandy, powdery sawdust and is brutally hard.
Thanks again for the advice. I am a career car mechanic but just love making things with wood.
16mm may be OK in a long grain cutting board but is far too thin for an end grain board. I would suggest about 35-40mm.
cheers
To be honest I would not even bother to spend all the effort in making a end grain board in 16mm it won't last 5mins
The most authorative source would be the manufacturer. Being primarily a "construction adhesive" it may or may not be considered "food safe." Simply use their contact page and ask the question.

Okay, listen to the experts, since I asked them. I am now making the board around 35 mm thick. It would be a shame to waste the time and effort just to see a failed job.
I like to think I have special gift at being able to cut large pieces of perfectly good timber into many smaller pieces.
Thanks for the help once again.
