I've gone as narrow as 3/16"and a bit wider for hunting bows.make sure to use 1/4 sawn material.the depth is that of a small chain saw file,also leave enough wood as to not file through the overlay.here's another, ebony on elm.never slipped once.
Some like motorboats,I like kayaks,some like guns,I like bows,but not the wheelie type.

Here are some pictures of the bow, it is almost ready for tillering. I put it in the house because it needs to dry completely.

Can I make your type of nock in my levers without gluing on some overlays?

It isn't a good idea to cut through the back at the nocks
failure is an option, everyone fails, it's how you handle it that matters.

So some 1/4" tip overlays are enough like bushboy said?

Yup as long as you don't cut all the way through them

You can also do an insert and then cut into the back safely.

 Like the sliver of horn or bone in a composite bow. A slot or a v in the tip with a tougher material glued into the slot.

I use a belt and disc grinder to shape my tips.it's quick. And easy.if I have time after work I will put up some step by step photo's

I've build some bows out of europoean hornbeam. It's a very dense wood. Most of my tries broke on the back cause of the very dense belly. You need a very thin limb when they get that wide. I prefer nowadays a narrow limb design with a shallow-d-section.
Good luck

This bow has thickness of 20 mm, if I get them thin, it will lose wideness because of relatively high crown. I'll see what it will do on tillering, will not speculate further before that.

European hornbeam is told to be very strong in compression, and moderate in tension. Crowned back in tension-weak wood (relative to belly) is pretty risky if you ask me.

I'd back it, but maybe that's just me.

Crown is not so pointing out despite what I said, I meant to say that it almost didn't allow me to make bow at width I want as sapling was relatively narrow. If I make limbs thinner now, before any work on tiller, it would make bow narrow.

Will blocks made from black locust heartwood function as a good tip overlay?
