I can let you have current and archive RH measurements from my Vantage Pro
2 for locking birchwood, Warrington area if it's any use.

Mark,

thanks for that. Are you based in Locking Stumps? My dad lives there! I'm in
Whittle Hall, between Great Sankey and Burtonwood.

From the data that I've looked at today, it seems like we rarely get below
60% around these parts and then it's only for a short time. If that's the
case, I'm going to have to do something to control the environment in my
garage - something that I was hoping to avoid on both cost and convenience
grounds. Anyway, if you have data that contradicts this, I'd really be
interested in it:

ps. whats the project ?

Oh, it's not anything gripping. Well it is to me, but probably not to many
others. I'm hoping to spray-finish a guitar using nitrocellulose lacquer. As
a long-time player, I've always wanted to have a go but the experts tell me
that nitro tends to 'blush' if sprayed above about 60% RH.

It's possible to use wood-stain and then apply something like tung oil to
seal and protect the wood but I'm not as keen on the visual effect of oil
finishes.

I have to admit that this project has been an eye-opener. Up until a few
years ago, I rarely went out of my way to look at a weather forecast. Even
recently, I really only ever looked at the big-picture details when I
venture out: Is it overcast, rainy, windy etc.

However, the project has led me to investigate RH, an aspect of the weather
that I've never really considered. It was on another newsgroup
(rec.music.makers.builders) that I learned that RH can be an issue when
spraying cellulose. So I started to look into that and it led me to here.

This is what I find fascinating and invaluable about newsgroups: Start
looking into something and you never know where you're going to end up.

FWIW, I suggest you find someone in the east of England who will let
you use their garage.

But perhaps better would be to heat the garage on a cold day. The
absolute humidity would be low, and by heating the air in the garage
you would create a low relative humidity. The best time to do that
would be on a frosty night or evening. You can check my idea out by
heating the garage and measuring the RH on a frosty night.

HTH,

Cheers, Alastair.

Aye, but the only mate I've got over that side is Kevin Keegan and he's a
bit busy at the moment ;o)

I think that's the way I'll go. Seeing some of the other threads on the NG,
later this week may be the time to do it.....
....other than the fact that I have so many other pressing things to do!

If you want to dry out your garage, you could always use the tumble
drier. So long as there is no wet washing inside it should be very
effective. They are designed to provide drying air!
