Shop and Tools: Tips and Tricks

Seen this in a video. Not sure if it's brilliant or stupid, as they didn't show it being used to lift anything. Probably stupid.

I guess it would all depend on geometry of the pivot. If the drill doesn't have enough jam to rotate while moving the piston a full stroke each revolution you could shorten the stroke per revolution to gain force and it would still be much faster than hand pumping.

Then again, how much time do you really spend pumping a bottle jack? Maybe on a bottle jack press?

this could be handy when i am using the engine hoist. i feel like it takes forever.
 
For a bottle jack like that, I'd just replace it with a screw jack and weld a 1/4" drive to the rod so you can use it with a drill or impact.

I have a half dozen or so of these OEM nissan screw jacks from 80's and 90's pickups and pathfinders that work great for this.

This is the rod. Easy enough to make a new one or just weld an adapter on to the end.

I have a few grinding wheels made for aluminum... Probably came from some auction. Never have tried them, I just usually use what is already in the grinder, and hardly ever mess with aluminum anyhow.

They work great in aluminum. They're designed to wear down extra fast, so I guess the aluminum doesn't get a chance to gum them up.

Of course I'm not the one buying them...

Look up "Alumacut" discs. They're impregnated with some type of oil that keeps them from getting loaded up and also works as a cutting lube. Probably very similar to the paste and sticks noted above.
 
these jacks ar the cats meow to through in the tool box on the trailer to fix junk back at camp. spread things open, lift shit, awesome little tools

same but with older scissor jacks. Like my Isuzu jacks from the early 80s, take a 3/4-19mm socket and are tough. Fit in tighter gaps if you need to spread stuff

According to the interwebs the above is an early 70 corvette jack, but looks very much like my Chevy LUV/Isuzu jacks that I have a 1/2 dozen of.

I hate scissor jacks, except for those times when you need the low clearance. :laughing: Maybe I've just never used a decent one, but they're always awkward and kind of jerky to turn the screw. Plus I don't think you get as much mechanical advantage as you do with a screw jack. .

All the modern scissor jacks I've ran across are garbage, so I agree, though early-mid aught caravan jacks are okay. Due to the geometry of a scissor jack you don't get as much force in the first 1/2 of the lift as you can get in the second half. Its not a linear progression. That said, I like how a scissor jack will go quickly from collapsed to up against what you're lifting, and in the case of vehicle lifting, as you get more of the suspension unloaded (read: more load) the jack's turn/lift ratio is slowing down and increases lift capacity.
I've probably butchered that explanation somewhat, but hopefully you get my drift.
 
I got tired of not having a brush to apply my Anti-Ox grease when working on electrical shit.
Thinking about those cool cutting oil bottles machinists make out of hydraulic caps and plugs got me thinking.
Off to the PVC box and I got these 1/2" cap, extension and pug. Drill hole to tightly fit the brush handle and its done.
Not earth shatteringly cool but it will be very useful.

adding to that
I know a guy personally that used a vacuum on a gas tank (I know that this guy put the exhaust in the tank)
But....ol Ronny decided to shop vac his tank out

I heard it a mile down the road, and they were finding tools 1/4 mile away

Ron is not smart :grinpimp:

While I was away at college, the neighbor of friends of mine from high school did something similar to that.

The neighbors were trading their car in at the dealer for a new car. The wife went out shopping earlier in the day and noticing the car was low on fuel, filled it up. The husband threw a fit. No way was he giving the dealer a full tank of gas! Mind you, this was when gas was about a dollar a gallon - or less. So probably $20~$25 for a tank full. He proceeds to pull the car into his garage, get out his wet/dry shopvac, and try to empty the tank...

Fortunately, he, his wife, and two kids escaped the resulting fire, but it burned the entire house to the ground. Mind you, my friends' father was the local fire chief.

that would make it the third firefighter that I am aware of that has burnt their own house down
probably deserves its own thread :grinpimp:

Make it 4. When I lived in Mammoth as a kid...we were in a mobile home park for the first winter. Hell of a snow year, second I believe only to this year. The Fire Marshall (or cheif) lived a few doors down from us, and was on the local news reminding people to dig out their gas meters so they could vent properly. I came home from school one day a few weeks later and his house had burned down....because of a propane issue because he didn't dig out his gas meter. lol.
 
Funny, my wife used to scold me for being so careless. I did shoot grinding sparks into a plastic bowl full of magnesium shavings from hummer run-flats. That was sitting next to my solvent tank. Fortunately the door out of the garage was right there and I only got some bright sparks.

And remember. Arson is a crime, being stupid is not

I was wearing my "I might be a mechanic but I can't fix stupid" shirt....out running the grinder. I looked down and my shirt was on fire. lol. Nice big hole in it. I'll not live that one down.

Slightly off topic, as I never burned my house down, but when did you live in Mammoth? I graduated high school there in 1984.
