If you get one, get the orange one, not the blue one.
I have the orange grinder, plus the next two larger sizes of orange to use when I need to hog out material. The 15 amp 9 incher is a monster!

I also have their blue 4.5" grinder with a wire-cup brush on it, and just bought a second blue one @ $9.95, plus a stack of flap-sanders for it. When they are that cheap I figure its worth it to just reach for a different grinder when I go from grind, to wire brush, to sander.

And a special heads-up. They are closing out the yellow jump-start batteries.

The 17 amp-hour ones are gone here but I got the last 24AH for $50 then less a 20% coupon, so $40 plus tax.

The new series look identical but gray with longer cables.

I'm going to try this battery to support emergency lighting. (The power was out here for 11 hours yesterday). I already have some 12 volt fluorescent lights that can be powered from a cigarette lighter plug. I might even try my inverter to power the DSL modem and router so the laptops get internet access! Maybe my next invention will be to send 12 volts straight to the modem and router in place of their power-wart transformers.

It's fairly easy to do. The easiest way is to just buy an adjustable voltage regulator. It's a 3-pin part and only needs a couple of resistors and capacitors to set and regulate the voltage. The only problem with these is that they are very inefficient, so if you are going from 14V (car battery) down to say 4.5V, you are losing about 60% of the battery power to heat.

However, if you use a switching regulator, you can do the same thing and only lose about 20%. Switchers are easy, just need more external parts.

The very easiest - they used to sell these at Radio Shack where they were supposed to plug into your cigarette lighter. They had a slide switch on the side that let you set the voltage you needed, and then there were several different plug options. Don't know if that is still available... Once again, very in-efficient since it is using a linear regulator instead of a switcher.

buy an adjustable voltage regulator.
I just climbed under the table to read the labels. 12 Volts DC for the router (Netgear) so that can run from the battery. And 15V DC, 1A for the DSL modem. It may run ok with reduced voltage. Or I can drive its transformer by the little inverter I have for car-charging my camera battery. This is 150/450 W and plugs into a lighter socket.

I have built simple power circuits like you describe. They worked ok but were a little klutzy. I would rather avoid that approach.

I suspect they'll both run from the car battery directly. Be aware that the car battery doesn't drop to 12V until it is nearly dead. A fully charged car battery can easily put out 14V.

What will save you is the fact that both are going into a regulator..

I was talking about using HF's jump start battery
40615-t.gif

as an emergency UPS to power the modem and router. There's no regulator.

I charged the battery overnight. The charge light went out and the built-in voltmeter shows 13.4 volts; 13.2 V with the built-in spotlight turned on. So I don't think I have an overvoltage problem. But I may have to find another DSL modem that runs on 12V if my present 15VDC one won't run.

I dreamed up this solution when I called the local utility to see how long the power would be out, and they told me to look on their website! :confused: Ok......., except my laptop can't find a wifi signal with the whole neighborhood down.

I just picked up a HF 1000 gram scale (97920) for about $9. I'm impressed with the quality and it seems pretty accurate based on my weighing several different coins. Probably not accurate enough to weigh powder for reloading, but good enough for most of the small stuff that I'll ever weigh.

I've got the 4" and the 9" angel grinders and they are great and I work them hard too - Extra set of motor brushes to boot! So far the only thing from HF that messed up was a car polisher that I tried to use for an angle grinder - (I don't recommend that - Ha) - Stripped the gears - and that was my own fault. - Anyone tried the Plasma cutter from HF?

Also found HF coupons in VFW and American Legion Magazines.

So there is a legal use for those?? A few weeks ago I was in HF and the lady in front of me was buying a small scale (not sure if it was the same one). She was acting kind of sketchy and mumbled some story about why she was buying 'another one'... something to do with 'her mom's dog ate the other one' ;) All the clerks were snickering after she left. :D

I'm sure you could use one to measure out drugs, but I use mine for weighing letters, small food amounts, a gold ring that I found and sold during the bubble, etc. It even has a feature where it counts items once you establish how much one item weighs. So you could use it to count out, say, 100 washers or nuts, etc.

I don't own a tractor lol but I found this thread via google and I picked up the 10 gal air compressor which seems to be pretty good I really wanted the 21 gal but they only had the 230v version in the store.

Like someone said on one of the pages I found out they had a store somewhat local to me (73 miles one way) so I decided to check it out. I walked out of the store spending $362 and somehow lost my receipt coming out and buying a extended warranty too :(

I did not buy the earthquake model impact but one that seems to not live up to it's 230 Ft lb rating. Which is item number 95310.

$2.99 nose hair trimmers.

Oh, heck no! Their gas powered weed whackers are required if you have more than 3 nose hairs. Otherwise, they just bog down and make you want to sneeze!

Dargo, I have to agree with you.

I bought the $4.99 electric shaver to leave out at the ranch. Forget it. It is obviously designed for the Asian complexion with light facial hair. It kept bogging down and stalling no matter how much I charged it. Off it went to Goodwill.
