Post subject:  Drybox built into workbench?
I have to work in a garage which is a good 50m extension lead away from a power source, so running a dehumidifier is going to be difficult for me for that reason if not the draughty door!

I was thinking of doing as much critical gluing as I can indoors but, and I don't know if this is workable/useful, I've been thinking of building building a "dry box" into my workbench (I also don't have much space).

I have a workbench I threw together that looks a lot like this....

... except of course it has a plywood top on it.

I wonder if I can give it a plywood floor and walls of 4mm mdf, sealed with "airtight tape", like this....

Image

... give it some kind of airtight door, maybe with perspex(?), and chuck in something like these...

... recharge one at a time so one is always running, and maybe that will help me combat humidity during my next build????

Is this going to work? Will it improve my situation somewhat?

Any advice is most welcome!

Thanks,
Nick

"MD100 does not over dry as only absorbs the excess humidity"

What constitutes excess humidity? Nothing below 35% but above 45% RH? That would be ideal, but I think this is something you would need to know before you can figure its worth.

Quite right, I hadn't really gotten that far. I'll try to find out! If not, maybe there's another way I can keep the box dry?

Thanks for the input, Alex!

EDIT:
The other facet to my question is, even if I keep workpieces in the dry box, clamping overnight in a gobar deck at ambient RH is probably going to render the effort a waste of time.... Or is it? I don't know.

A thermostatically controlled light bulb? I think some people use them in dry boxes, but I think the problem might be the box being too dry, so the RH needs to be controlled somehow.

Just noticed these too, http://www.ebay.co.uk/itm/PINGI-450G-XL ... be7359e2... Not sure if they're worth thinking about. It is only a small space. You dry them out in the microwave.

Problem with the lightbulb again is power at night when I can't have the extension running out to the garage... Wish I had a spare room to work in!

I'll put a hygrometer in there and keep track of it daily. Do you think the walls and floor will create a tight enough box?

That's in the blurb for the bag version I linked to.
