Vacuum Impregnating Wood for Flight Arrows?

[Del the cat]

I'm considering vac' impregnating arrow shafts with one of the wood hardening fluids/preservers.
Anyone tried it? I don't want to waste time and money if the the consensus is that it's a fools errand...
But, if people think it's worth the experimentation, I'll give it a go and report back.

vacum impregnating works well enough, but which resin are you asking about?

Give it a shot, I'm interested

Bamboo flyrod makers get good results from that but i think you'd be crossing a line regarding rules.

Was thinking of Minwax wood hardener ... regarding rules... GNAS and ILAA doen't allow bamboo...
I'm prob' not going to be formally competing anyway, not many comps in South of England

There was an article on making shafts heavier with  a minwax soak but I don't believe it increased spine.

Any idea where that was?

An article in the mag years ago.   In a nutshell the arrows got heavier.    I can try to find it and double check if there was any additional benefit.

 The guy doing it just wanted a bit more mass in his hunting arrows.

How much mass would you actually save? Arrows aren't big and air isn't heavy.

The aim would be to get a stiffer shaft at a smaller diameter, consequently having less aerodynamic drag (wind resistance)... this is for flight shooting where even small differences in dimensions or stiffness can make a big difference to arrow performance. The difference between a good arrow and an ok arrow can be 30 yards.

the minwax hardener I used on a different project was mostly thinner and made for brush applicaton, a nasty solvent thinner. Would a resin made for vac impreg be better?

Wood that has been modified with impregnation resins can be used for structures requiring enhanced dimensional strength

Ok, I thought this meant a vacuum inside an arrow.

Del look up videos on stabalizing wood. The resins for vacuum use are different to the Minwax stuff. They are drawn into the woods pores after the air has been sucked out under vacuum(submerged under the resin). Normal air pressure is then alowed back into the chamber and it is then, under air pressure, that the fliud is drawn into the pores. 
I've got a bit of experience with the process. Unfortunately it wouldn't be of any benefit to flight arrows. As Pat says all it will do is add weight without increasing stiffness.

Ok, ta ... I'll have to find something else to do with my pump then
