Well, last night I picked up babby's first welder, the el-cheapo Harbor Freight 110v 90a wire feed flux core welder:
http://www.harborfreight.com/welding/mig-flux-welders/90-amp-ac-120-volt-flux-cored-welder-68887.html

My parents gave me a $100 Harbor Freight gift card for xmas and I couldn't think of anything else I needed from there (I could use a good electric impact gun, but the ones at HF are crappy and not significantly cheaper than some of the other, better brands, so not worth it to me)

So here's my first time welding, on what was clean, new 1/8" cold rolled sheet steel:



The cheap flux core wire that came with it is made in China and is (from what I've read) notoriously crappy and creates a lot of spatter and crud; from what I've heard from other people who've bought this welder, getting better wire (and moving from the .030" it comes with to .035" wire) helps a lot with getting cleaner welds. The first attempts were just as boogery as I'd expected, but after a couple tries I got the wire feed speed dialed in better and was starting to get the hang of it (the ones at the bottom of that pic are the newest, the really boogery long ones in the upper middle were the first beads).

I have a ways to go :v:

The duty cycle on that machine is very low. Splatter gets worse as you use it if you don't let it cool between welds.

I've used it side-by-side with a Hobart 140 loaded with the same wire at a local hackerspace, and both machines started out making similar quality welds, but the HF box started spitting and sparking while the Hobart kept going twice as long.

Is a good welder to mess around with from what I gather though. Plus its only a 100 bucks so its not a complete loss when it dies.

I have a lead on a miller welder.... I hope I can get home quick enough tomorrow to buy it.

BTW definitely get Lincoln wire, Lowes or HD should have it. I'm running Lincoln .030 and it is a ton better than what the machine came with.

Supposedly (internet rumour I've read, so I'm not entirely sure how much I'm willing to trust it) the spools of wire they sell separately at HF is made in Italy and is the same stuff that Lincoln sells, it's just the pack in spool that comes with the welder that is crappy Chinese wire, so once I use up the spool that came with it I might pick up a spool of actual Lincoln branded wire and a spool of the HF wire and do a side by side to see if there's a difference or not.

Once I get more experienced I'll probably upgrade to a nicer Hobart or Lincoln unit, but for learning and small, non-critical jobs it seems like an ok unit so far. I'm at least getting full penetration through 1/8", which is all I really could ask for at the moment.

As posted above, you can use them with a hand drill to clean up bores, in which case people will often refer to them as glaze-breakers, primarily to give a fresh surface for new piston rings. You can also use the smaller sized ones on things like brake master cylinders when doing seal kits, they can often rescue a borderline surface rather than having to replace the unit (and in some cases means you get to spend :10bux: on a seal kit rather than ten or more times that on a new cylinder).

A caveat is that you probably shouldn't use them on things like BMWs with Nicasil lined bores, as you'll likely just trash the coating.

The tips for the screen seal cutters are available separately, they bolt in.



If they're factory catalogues/manuals (and you're not inclined to collect that poo poo like I am), you can probably sell them on for a reasonable amount. Check what they're going for on Ebay.

It looks large enough for the tiny pistons in an MG, otherwise I was going to suggest it was probably for the brake slave cylinders. Those have lovely seals and seem to continuously leak despite constant replacement and refurbishment. If he was an MG guy, I bet he'll find a smaller one around there somewhere.

Has anyone found a transfer pump that works for more that a use or two? I'm talking about the kind that screws onto the bottle of oil. I've bought a couple of different ones at the parts stores, and they all brake in various stupid ways. Usually I get about a liter into the differential and then the pump smashes through the plastic cap and sends a spring into the bottle, leaving me a couple liters short. Usually this happens at around 9:01pm when there's no chance of getting another one. Luckily my 8.8 axle has the fill plug on the opposite side from the cover, and it's at an angle so I was able to make a funnel work.

I usually pay about $10 for the white plastic pump that's available at the stores. Has anyone found one that is reliable? I don't mind a little leaking here and there, I just want to be able to fill stuff without breaking pumps.

I use a length of garden hose and a funnel. The hose is just right to go into most fill plugs, so stuff it in, run the hose up/out to where you have room to pour, jam a funnel in it and cable tie it to something. Then you can just pour down the funnel from a comfortable position rather than loving about under the car.

Heat the oil up first, it flows easier and doesn't make you push so hard, which reduces the breaking.

I just got back from buying 5 feet of clear tubing from Lowe's (<$3) to do exactly this. I bought the smallest diameter hose that would fit my smallest funnel so that there is less still in the hose once the diff starts overflowing.

I usually poke a small hole in the bottom of the gear oil bottle and push the blow nozzle from the compressor into it. Maintaining a small positive pressure in the bottle will force the oil into the diff or tranny really quickly.

Hell with the liter and gallon jugs for anything but trail repairs... get it in 5 gallon pails and buy this: http://m.harborfreight.com/steel-lever-barrel-pump-3352.html?utm_referrer=direct%2Fnot%20provided

It is a bit bigger than I imagined from the listing but I am very impressed with the quality of it. Everything screws together very well with no slop in the threads. Hella excited to use it, and it even has an attachment that replaces the adjusting screw on a pair of vise grips so you can clamp onto stuff that the other attachments won't grab.

I was having trouble getting my wheels off, so I paid a guy :10bux: to loosen them for me. When his impact gun didn't work, he busted out a breaker bar that looked like this.



The connection between the driver and the bar was solid and it didn't look like it was experiencing any of the twist that I was getting when I put too much pressure on my store bought breaker bar trying to get the bolts undone.

Is this something you can buy or was it a custom deal someone welded together? I've never seen a bar like it and it would have been much better to use than what I have now.

(Mine looks like this and was twisting at the joint.)

The thing about his bar was that he was able to give it a few sharp pulls and the energy went straight into the bolt. When I do the same with mine, most of the energy goes into twisting the bar.

I guess my better solution is to just not let anybody touch my wheels, ever. The last place that took them off was a shop that I've been to before that I've been really pleased with because they used a torque wrench. I guess this time they just used an impact gun for about five minutes to make sure the wheels wouldn't fall off.

Is your breaker bar a 1/2" drive? Because I've found they normally cope with even the worst wheelnuts*, to the point that the stud would let go before the breaker bar was damaged. I do however have a 3-and-a-half foot long 3/4" one for big stuff, and there isn't a lot in automotive applications that you won't cope with using that. Things like M20 nuts blasted with two decades of road salt put up a bit of a fight.

I've found I almost never need a cheater bar, but I'm a pretty big guy.


*Land Rover's M16 studs are a bit of a special case, but that's moving away from "normal" cars.

Gummy Bear Heaven ... It's where I go when the world is too mean.
Yeah, it's a 1/2 bar from Farm & Fleet. Don't know the brand. Usually I don't have to strain at all, but it's because I torque everything down properly. I had to use a cheater bar once when I got the wheels back from the dealer (back of the envelope calculation came out to ~400-600 ft-lbs!). It just wasn't working this time and it was cold and I didn't want to deal with it.

I could hunt down a better cheater bar. I was using the handle of my jack, but the difference in diameters is huge and that was adding even more slop that I wasn't comfortable with.

I am not sure why that 45 degree bend would do anything good for him except make it easier to accidentally bend the lug sideways instead of turning it.

My typical setup for difficult lugs is to set a jackstand about a foot away and at the same height as the lug, put the 4-way or a socket and extension across it, then put a cheater pipe on it and go at it. If you work it right, pushing mostly down on the handle, the jackstand keeps off axis torque to a minimum, which reduces twist/roundoff risk.

If the drat thing gives me poo poo with 1/2 tools, it is time for 3/4 drive.

I've found this is very useful myself, save for with a 4-way wheelbrace - they often seem to be quite cheaply made, and I've put a good twist in one before using it by hand.

It kept a short distance from the bar to the bolt while keeping the bar away from the body of my car! (and my car has bolts that go into threaded holes in the hubs(?), so bending lugs isn't a concern)

Twisted my cheap lovely 4way this way, but the larger one is fine with it. Fortunately 19mm/3/4" is the smallest lug nut I work on.

Worth noting that static and moving torque values are not the same, they don't even have a linear relationship because materials, thread design and quality and condition, temp, corrosion, lube type and quality etc will all change the numbers.

Look at plastic Gatorade bottles for a low-hanging-fruit example: the threads are shaped to make it take around three times as much force to loosen as they do to tighten.

Allegedly it is stronger than the base metal, at least on 6061 and cast alloys. Not sure I believe it.

I had a lot of trouble getting it to actually bond to the base metal, probably because of how much/how little heat I had available. Their "weld with a propane torch!!!" schtick is great and all but the amount of heat you need depends entirely on the size and thickness of the parts being welded, as usual, and it's even more important on aluminum because it conducts heat so well.
