Doesn't hurt to pin both parts with screws when finished...…..Art
You can use those pin holes to let flew the epoxy in the sleeves. I experienced when you slide the sleeve over the glue, it is every where but not where you want it. With the HG you will get the Epoxy fluid enough. Tape the ends so it doesn't rinse out, but leave a hole for the outcoming air. Also don't make the wood joint to tight, better a little bit thicker glueline than a bit here and there.
Just m2c.
