Re: Rust prevention

 

Yes.? There are many "oil pan heaters" and you will also find "block heaters" for cars to use in cold weather and they all seem to be vastly more wattage than would be needed for an indoor application of warming up a few cubic feet of air.

I was going to add in to try a magnetic oil pan heaters , but the smallest that Kats makes is 200 watts , But maybe? that a usable wattage . I did a search for magnetic oil pan heaters & ended up over on the big A ( surprise ) & came across these . They make them in several different sizes . Maybe ya can use one of the? Katz ones & throttle it down with a Variac if ya just happen to have one of those laying around .

I wonder why a light bulb would be any more dangerous if left on 24/7 versus, say, 2 hours, or 8 hours?? ?Or whatever number of hours in the millions of homes over a hundred years or so.? Want protection around the bulb?? Use a regular caged shop drop light.? The light bulb seems a bit ubiquitous to have any particular danger, even if left on all the time, in my opinion.? But a heating element alone does make more sense, the bulb merely being convenient and available - well, incandescent USED to be easily available.

Regarding any type of pad whether designed for people or reptiles (and the distinction may blur in some cases), why not use a heater designed for the purpose that comes in a solid packaged form.? Like the aforementioned cabinet heater, or enclosure heaters.? They are designed for industrial purposes such as this.

Or, if you want to stray off the industrial reservation, you can search for "terrarium heaters" at Amazon.? You will find some pad oriented things, but also solid choices including a "ceramic heat emitter" which conveniently screws into a light bulb socket but is a heating element only.? All sorts of things that are not "pads".

You can also search the group archived messages as this topic has been discussed before at least a couple of times.

Another reason to NOT use a light bulb, the covers are flammable.

I have most often heard of people having a cover over the machine and then a light bulb (incandescent for the heat) underneath.? As well as the usual "oil it" a lot.

In this "Practical Machinist" blog, the light bulb and many other suggestions are offered.
