Hi Folks,
I made a HLD-style bow out of elderberry and finished it with a few coats of Danish Oil.
Now there is a crack in the back, across the bow, probably just the outer ring, since the bow did not explode...
I am considering backing the bow with flax, using PVA glue, and then re-finishing with Danish Oil.
Would the PVA glue adhere to the finished back, or would I need to sand off some to get better adhesion?
How much would I need to sand off, ie. how deep does danish oil penetrate the wood (elderberry)?

Crack across the back? How long , how deep?
IMO it is not worth the effort to do a backing.
Better make a new one, it is the same time.

I agree with the above... but if you insist on a repair, then use white spirit and wire wool to take off the Danish Oil, then coars sandpaper to key the surface.

I also agree.

You will need to re-tiller if you back it with flax. Another option to consider is to put a patch over the crack area and not back the whole bow. Same procedure to remove the oily surface and get to clean wood, but only on a small area instead of the whole bow.

Hey, Mark, sorry if this is a thread jack, but could you tell me a little more about this? I've been thinking about making a chokecherry bow (only semi-decent bow wood around here) and backing it with flax or other plant fiber (milkweed or dogbane) if I can't find any sinew. What would that do to bow performance?

Perhaps scraping or sanding down the entire surface of the back below the bottom of the crack then backing with a thin layer of Bamboo would salvage the bow while improving performance.
