Like, if you look at a PWM-controlled circuit under the hood, like the idle valve. PWM DC isn't the same thing as true AC, but a multimeter can't tell the difference. This is one reason why oscilloscopes are so nice; you can use them to visualize the magnitude of the ripple relative to the DC carrier, to determine whether or not it's going to be a big deal. |

I have the 20 ton and I am very happy with it. I wouldn't expect the 50ton to be any worse.

The 20 is the one to get. Some reports of the cast arbor plates exploding, swag parts makes plate steel ones.

Well I just picked up this charmer on Craigslist for $50:

Not a harbor tool but definitely pretty cool.

Picked up the 14" cutoff saw the other day.
It works. Things get cut. $60 with coupon |

Tell me why this is significantly better than large diameter wheels or the cool tank tread things. Does it not roll down stairs?
The tank threads would have to be too long not to get caught on each stair. |
bought more of those windshield repair kits from HF
they still work okayish, but for some reason the glue doesn't dry anywhere near as effectively as the ones I got before. kinda annoying, since it's like 100F here, way hotter than the time I used the last set |

Because with large wheels you are still stuck with going over the corner of the stair with the full diameter of the wheel while with this the "diameter shrinks".

So I finally got around to my Harbor Freight 90a welder project. Pretty simple stuff - routed the power on the far side of the main transformer through a 150a 1200v bridge rectifier, to convert the AC to DC. Mounted the rectifier on the outside of the case for better cooling.
http://i54.photobucket.com/albums/g1...a.jpg~original Sent the positive and negative output from the rectifier to a bank of three 63v 22000uF capacitors, wired in parallel, with a 10w 150ohm bleed resistor. http://i54.photobucket.com/albums/g1...1.jpg~original Electrode was wired to negative, ground clamp to positive. I also added a 90mm computer fan for better cooling. http://i54.photobucket.com/albums/g1...v.jpg~original Total cost for this whole operation, including the cost of the welder, was less that $90. For that money, and for my hobby needs, I suspect this is going to be a capable little machine. Now I guess I have to weld something! |
Has anyone tried the HF safety wire pliers? Junk? Or useable?
|
They're usable, but pretty darn bad. The only thing I've used them for are TSE 2-piece rotors, and it was a pain. I'm used to using very legit pliers from aircraft spruce, so maybe it's just me. But you kind of have to assist the pliers to twist, and assist them to retract. They also don't clamp very evenly so you have to make sure you're clamping the wire in the spot that actually makes contact.
