I like it when I hear something new I can rag Carol about. next time I see her I'll shoot one of my beeswax finished bows and ask her what she thinks of my slow bow... lol

Yes please do, I'm genuinely very interested why she believes this is so and how it works. It must be backed up with some science if true. By the way, I don't think she has a problem with beeswax.
Cheers,

I have heard it said that using linseed oil on a lemonwood bow will make it go weakl and floppy. I can only guess that this is because it isn't waterproof on its own and bows would have absorbed moisture if left in a damp room.
Now the problem with lemonwood bows is that they dry out in central heated homes. the bows I have seen break look like they are bone dry.
I can see no way that a surface-film oil finish which truly does just stay on the outer couple of hundredths of an inch can seep deep enough into a bow to affect the wood cells in the way they say it does. Moisture and set slows bows, not a finish! IMHO.

I remember reading some of the American old timers saying that an oil finish was bad for a bow(I'm guessing osage and yew). Made a bow sluggish! Like Mark, I'd bet it was moisture and not the oil. Most of the finishes I've used, both straight boiled linseed and tung oil and Tru-Oil are surface treatments. Even when using dry heat, and oil to prevent scorching, the oil doesn't penetrate very much. Usually a few scrapes and you have eliminated the oil. I would guess that a wax or oil with shellac finish would give better moisture protection if it were maintained. Pat
Rod:
Check the table on p.208 of Hoadley's "Understanding Wood". Tung oil (which is the basis of Danish Oil) does not perform well beyond 1 day of immersion.
Shellac and paraffin wax on the other hand perform far better over a longer period of immersion.
I think bowyers like Danish oil for it's finish and speed of application and drying, but I have not found it to be very useful as a sealant if out all day in the pouring rain.
And believe me, in the NFAS this is not unknown.
And on a yew bow, a more modern coating that seal well but forms a hard surface layer is not much use, since you cannot burnish out a ding without the varnish layer flaking off.
