I am planning
I am planning to turn some bowls using small pieces arranged to make designs like checkerdboards, spirals an the like using different woods. I can’t avoid that some of the gluelines will be end grain to end grain.
I have seen in books and magazines turnings made like this, so I must assume that it is possible to solve the problem of weak joints; so my question is:
Is it OK to use just ordinary yellow glue or should I use something special like epoxy, etc. ?
And, since we are on the subject,
Is there some way to glue two pieces of end grain with some strength in the joint.? Are there differences in the various glues regarding this matter?
Thank you for just reading.

I guess if had to I'd trust G2 epoxy from Lee Valley. but only if you have a big enough face to glue up.
I don't know of any adhesive I'd trust to glue end grain to end grain in board form...suggest a scarf joint.
Justo,
I think the technique you are referring to is called segmented ring construction. I have made several bowls like this using regular yellow glue and never had a problem with delamination. The strength of the joint comes not through the segments connecting end to end, but though a good glue bond between layers, on the flat sides of each piece. There is a good description of this type bowl construction in Dale Nish's book, Creative Woodturning.
I have found this is a good way to use up all the small scrap pieces of hardwood that all woodshops accumulate. The diameter of the bowl ends up to be about 2 1/2 times the length of the longest side of each segment, using 8 segments per ring, cutting 45 degree miters on the ends of each segment. GP
Thank you. This answer is exactly what I was asking for.
