quit using stuff that uses batteries if you absolutely must use them use double or triple A..
I have my investment in the devices that use the batteries. Normally the batteries last long enough that the replacement isn't a problem and actually they are not terribly expensive, the biggest problem is that if you don't have a back up you can get caught without the device working when you need it.
The answer to my question is that it probably was not the heat in the shop that caused the batteries to die, but was just that batteries die on their own and that is what I was wondering about.
For what it worth, while the Wixey angle gauges are nice devices, a draftsman template for angles is, or I am told, and use them for important setting such as squaring the TS blade with the table and the fence on the jointer to the tables.
Years ago I did use a set of dial calipers that did have an actual mechanical dial and I liked it just fine. My vision is not so bad that I could use one of them, I just had not ever tried the one's with the "idiot prove read-out" and so I purchased a couple of them and found that I like them. As far as accuracy goes, I don't know for sure but I have read that dial calipers aren't accurate to much closer that about .002" which is good enough for wood working. I'm more concerned with two parts being of the same width or thickness rather the actual width or thickness and the dial caliper is fine for that for me anyway.
You guys that know more about woodworking and broke me to lead in regard to accuracy with wood working, it took a while, buy I finally got it, thanks.
The clean up on the shop was such that the shop is probably considerably cleaner than it has ever been since I started using it seven years ago. I should be able to keep it in fairly good shape now with the use of an air hose and a broom.
I'm going to store most of my hand held tools in a large freezer which should keep them in a more sanitary condition when not in use. The freezer of course is not plugged in just in case anybody is wondering.
My first under taking, when I finally get back to shop after the weather cools down will be to master the new Whiteside miter lock bit. I have the Infinity bit pretty well figured out but before Nick put me on to the diamond hone to touch up the Infinity bit, I bought a copy of Whiteside's bit and so I have to figure it out, I don't think that it will be that difficult to do now that I some set up blocks that I made with the Infinity bit. The blocks are just close for the Whiteside bit but slightly different or so I remember the only time I tried to set it up which waw quite some time ago now.
One of the best indicators of my getting well is that I find that interest in getting out to the shop has really peaked compared to how I felt for so long when I was recoverying, during that time I didn't care if school kept or not, that feeling seemed to last for ever but has finally demishied and that is very good.
Duh, just had a thought, having back up batteries is not the answer to batteries going dead in a device, a batterie on a shelf waiting to be used will go dead just as fast it would if it were in a device with the device turned off.
Makes me wonder what the shelf life a such batteries are where you buy them new, ummmmm?????
Just read that when the dial caliper is turned off, the only thing that is turned off is the display and that the battery may still be drained. That doesn't sound right to me as the display should be only thing that draws from the battery, but what do I know?
