Title: Black Locust: Worm Hole? Should I be concerned?
Post by: PaSteve on October 11, 2019, 07:37:47 am
This is a lightweight black locust bow I'm building. Going for 60" ntn and 25#@24". While working the belly this hole appeared. The limb is not quite at floor tiller but getting close. I stuck a pin in there and it almost goes through the limb but bottoms out before going through the back. Should I be concerned? Possibly fill it with saw dust and epoxy or super glue?  The hole is about 3/32" in diameter. Thanks for replies. Steve

I would be worried, the thin wood left at that spot might compromise the wood on the back.

Steve-o, if the hole is straight through without collateral damage, then continue on, but drill it through first, don't leave that thin bottom end section intact.  If you think they may have a cave dug out within the limb, start another one.

I was just working a BL stave that had a pretty similar hole and found an excavated area the size of a half dollar.  You never know what lies beneath the surface...that has happened to me a couple of times, so I am pretty leery of worm holes.

I just built 3 Elm bows that had  rotted knots, crooks,and turns etc. I fixed some pretty big knot holes . Some ran straight from back to belly, and some ran horizontal. I made sure  I cleaned all the rotten wood, and put Elm  saw dust, and  crazy glue,packing the dust as tight as I could. No problems yet. Go for it.

  Elm will tolerate things that black locust won't because of the inter locking grain. I have used elm boards with massive run outs and had no problems.

I have used that deal with about every wood I have  ever used. Not just Elm. Has always worked well for me.

Thanks for the replies. I'll proceed with caution and plug it hoping that it may tolerate a light draw weight. If not, at least I'll learn something.

If you want to be 100% sure, drill and plug, then back it with rawhide or sinew.

Some of the BL around here in my yard started having insect holes. It was multiple holes per stave. Thankfully, I did not see any such holes in the last BL stave I worked.

Truthfully, these staves found their way to the wood stove.

Since you started it,  I would drill it and plug it. I would use a wood glue. It would help  to leave extra wood around the width and tiller that area slightly stiff.

I would not trust it in the deer woods.

Innocent looking bug holes often do this below the surface.
