Warning! I'm gonna whine about what went wrong today in the shop

Dec 14, 2005 26 Replies

First thing that goes wrong: The battery dies in one of the Shop Fox DC controller remotes. I take out the battery and check it on a battery tester. Can't get the needle to move off zero, but how can that be? The remote just worked a couple of times today, but not consistently. Open up a new package of 9V's and check it to be sure the battery tester is ok--it's fine. So I walk back to the shop to install the new battery in the remote when...damn!...I touched the battery to the connector w/ reverse polarity for a split second. Then I snap the battery into the connector, expecting it to work. Wrong! The indicator LED lights up dimly with no buttons pressed; not a good sign. My worst fears are confirmed when I press "on". Dead as a doornail. Wonderful. Out of warranty. Go on line to find the Shop Fox phone number. give up; call the store and get the 1-800 from them. Call Shop Fox; "no, we don't repair the remotes".



Now I know this is going to cost me more time and more money to correct. Because I've had a couple of bad Shop Fox remotes already, I figure why give them more of my money; I'll get an X-10 unit.



I call Radio Crap at the nearby mall; the kid on the phone with the worst job at the mall (other than wearing a funky costume and jumping on lemons all day) says he doesn't know if they have what I'm asking for. So I drive to another RC a bit further away. The kid there offers to help me find what I'm looking for and proceeds to give one tidbit of good information on the remotely controlled outlets, and then follows it with obviously erroneous info (I'm reading the package while he's blabbing to me). We decide I'm right; well actually, the package info is king, and it seems as if a key chain remote and an outlet will give me a remotely controlled outlet. Pay the guy; drive home, head back into the shop, read the directions and WHAM! Screwed again! In order to use the remote, you have to press a button for 3 seconds to get it to register with the Controller? or Big Thingy That Looks Expensive in the instructions (they went all out to put a picture of the Big Thingy That Looks Expensive right on the instruction sheet where I'd learn all about item number THREE that I didn't buy). Mutter a few choice words, put the outlet and remote back in their respective blister packs and call the store. The kid makes 2 abject apologies and offers to refund my money when I "bring it all back". He doesn't understand I already KNEW I could "get my money back when I bring the 2 parts that won't work without the Big Thingy That Looks Expensive".


I almost head back to RC with the 2 parts that won't work without the Big Thingy That Looks Expensive, until I imagine how much worse the traffic is gonna be in late afternoon. Another sigh, and I decide to return the 2 parts that won't work without the Big Thingy That Looks Expensive, tomorrow.



Back out to the shop to mill some walnut. I keep getting 1/4 wide marks on the wood as it exits the DeWALT planer. Shut it off, grab a flashlight, crank the handle 7,680 turns to raise the head far enough to look at the rollers and blades. don't see anything out of the ordinary. Grab another piece of wood and feed it in, noting exactly where on the



13" wide table it's going so I can figure out where the marks are coming from exactly. (That took about 4,000 turns in the opposite direction to get the head positioned to plane the test board.) Now I can see how far from one end, the marks are. Another 4,000 turns to raise the head back up for another look-see. STILL don't see any marks on the rollers or anything out of position. the blades look pristine. This is the sort of problem that should be easily solved with a flashlight and a close inspection, yet I don't see ANYTHING out of the ordinary. I'll post a picture in a bit...

Now that I've eaten supper, I'm afraid to go back out in the shop, because sure as hell, this stuff happens in threes. Either some equipment will break down, or it perform poorly, forcing me to regroup and abandon the project I started this morning.

What is wrong with this picture?

It was out of warranty by TIME, so regardless of the problem, it's on my dime. They have a 90 day warranty; I've had the unit over 2 years. I've seen plenty of remotes and other products have the batteries installed backwards for a moment (it's usually the wife that does that sort of thing, right? :) ), with nary a problem.

that doesn't work, maybe they can supply one.

Know where you are going with this Ed, but I'm inclined to agree that if this were within the warranty period, it could have been covered with the OP feeling no ethical qualms claiming a replacement.

Given the current state of engineering and our level of technology, I'd be inclined to label this as a design flaw. i.e. Double-E who designed the remote should have taken into consideration the possiblity of someone reversing polarity on the battery, peer reviewers [they did do peer reviews on the design, right?] should have caught that, design reviews should have caught the potential, and any Quality/logistics engineers associated with the design should have identified this failure point and required mitigation/redesign.

Dead items due to reversed battery polarity should be a thing of the

60's, not the 21'st century.

I can't help much with the other stuff but those 4000 turns go allot faster with a cordless drill driving them. Have a happy holiday there. Count your blessings.

Given the incredible prive tag of .4 cents for a protection diode you are sugesting to put the manufacturer out of business by needlessly increased cost?

As a big german electronics BORG advertises: "Avarice is randy..." (In german this has at least an alliteration: "Geiz ist Geil")

Had the same problem with one of my Shop Fox remotes. Changed batteries and the one wouldn't work again. Just used the other remote until one day i remembered it had a on/off switch on the side. The switch was off. Did you check to make sure you didn't accidently push the very small on/off switch on the side of the remote to off? --dave

There is a design consideration to be considered.

With the ever decreasing operational voltages that newer ICs use, a diode voltage drop is greater fraction of the available supply (battery) voltage.

If this is a remote with a 12V battery, then 0.65 V or so isn't a big factor. However, with some of the new devices running off 3 or few volts, you're cutting into the supply pretty heavily. A Schottky can help but it's still an issue.

You're right of course. What was I thinking? :-)

I like that!

+--------------------------------------------------------------------------------+ If you're gonna be dumb, you better be tough +--------------------------------------------------------------------------------+

I believe the OP indicated this was a 9V battery. Still, the trade between protecting against catastrophic damage in what is a highly likely event (reversed polarity applied) and having to deal with the voltage drop to protect against that event seems to come down very heavily on the protection side.

Do you have a cite for that? Sounds more like urban legend than reality. There isn't sufficient volume in defense systems that the savings accompanying removal of a component like that would even come close to paying for the cost of the change drawings.

Thanks for the link, Wes. I followed the instructions, but no joy.

Dave

Better than my shop time!

Dave

Each time I have to raise or lower the setting more than a "skosh", my cordless drill operated router lift comes to mind. There is no provision on the 733 for an "assist".

Dave

oh yeah. I've slide the switch back and forth a number of times.

Dave

If you're gonna be dumb, you better be tough

+--------------------------------------------------------------------------------+ yup. 9V.
