    Going to put a coat of paint inside to keep the dust down?

    I will be using filtered air in an essentially clean room. It will have linseed oil coating as well. No paint though.

    Just don't store fresh film or paper in that room for quite awhile. Linseed oil never really cures until it actually begins failing. So it takes months and months to fully outgas. Faster drying formulations are more likely linseed alkyd varnishes, now rather uncommon, or else tung or oiticica oil derived instead. Back when we patiently hand-rubbed linseed oil onto gunstocks or hardwood furniture, the heat of hand friction was actually making the linoleic fatty acid chain longer and more stable, essentially turning it into an alkyd, analogously to how it is done industrially in heated vats. So-called "boiled linseed" oil does not have that same quality. Better to seek out a fast-drying sealant coat like real shellac. Shellac will water spot to some extent, not as bad a linseed oil. But heck, the device won't be in a furniture showroom anyway.

    That is interesting. Am trying to keep the natural wood showing thru. Nice thing about AZ is I leave it out a few days and any wet atuff will get cooked off ��.

    I will look into this further.

    I bought a new one some 30 years ago and never regretted it

    A clear lacquer sprayed on, then a light sanding to remove the raised grain and another coat will give a smooth surface that can be wiped down without shredding the paper towel. Lacquer dries fast but no idea about how long it would outgas. I’d give it a week to be safe.

    Years ago, I custom made mine to be just the right size.

    I opted not to include a fan as more trouble than it was worth. So, I process film one day, and then print it on a subsequent day.

    The drying cabinet has worked well for me ever since.

    True nitrocellulose lacquers like Deft dry very fast. The problem is that they're highly flammable and really bad to breathe, and in fact, are OSHA illegal for pro use, though in some States it seems to be the national pastime to violate the rules and outright blow up your own cabinet shop, along with yourself. Was that last cigarette really worth it? They're also soft and fragile. Substitute acrylic lacquers are much safer, but create an electrostatic surface which attracts dust.
