Gluing end grain to build turning block

I'm hoping to make a pepper mill that looks like the lighthouse in the attached picture. I would plan to glue up alternating pieces of redheart and maple to make the stripes. The thing that has me wondering is that they will be all end grain glue joints. Any ideas on how to ensure these joints won't fail after the mill is drilled and turned?

It depends a lot on wall thickness or surface to surface area. Also the type of glue is important. Use epoxy. I did a test many years ago gluing 3/4" square pieces of wood end grain to end grain. I was amazed how weak the joint is. I clamped one end in a vise and slid a 5lb weight out the rod past the glue joint. All of them broke with the weight no more than a few inches past the joint except the epoxy which held until it got about 6" out. Still pretty darned weak. I even tried using a glue sizing on the joint which recommended by many as a good way to glue end grain to end grain. Made virtually no difference. I tried Gorilla glue, CA glue, yellow glue, hyde glue and epoxy and I think another brand of Polyeurethane glue. CA was the weakest. Next strongest to epoxy was yellow glue where I applied thinned glue to the surfaces and let it sit for a while before applying the full strength glue. Still a very weak joint and only marginally better than the plain glue. Gorilla glue and the other Poly glue was amazingly weak.
I have however turned a fair amount of pieces similar to yours and not had a problem. If all the pieces are end grain and you have a fair amount of surface area you should be OK> I am currently making some salt and pepper shakers glued up this way. The top area only has a wall thickness of about 3/16. It is only 1" outside diameter but so far all have held. I'm on my 6th or 7th one. It's actually tapered near the joint so it's probably closer to 1/4".
