I wish I grabbed a photo. Saw a guy who was working on the front driver's side of their cover. To do this, they drove the front of the car up two ramps (looking home built), then jacked up the corner with a hydraulic jack placed on angled part of the ramp itself. No jack stand, obviously.

Fun fact - you can actually do a DIY metal disintegration machine with a tombstone stick welder, cheapie hand engraver, and some plumbing fittings. It's the single scariest tool I own though.

We have a small hole EDM (a smaller CNC version of that machine) at work. We use it to put .020-.050 holes in hardened steel as start holes for our wire EDM machines... and also for burning out taps on occasion. Our EDM guy used to work at another shop where they had a small hole EDM machine and nobody used it for anything other than burning out taps until he came along and showed them how useful it was for making wire EDM start holes.

GnarlyCharlie4u posted:"125~150 amps..." The metal is a far better conductor than the rag or you. Still probably not the smartest thing. Wire EDM machines cut in a big tank of water for cooling and flushing the metal particles away. If you stick your hand in the tank while it's cutting you won't feel anything until you get close to the wire, then it starts to tingle more the closer you get. I was never stupid enough to get closer than where it started to tingle, but either way you're mostly safe if you don't actually touch the wire. The water is deionized and acts as an insulator.

yeah, those things only run at like 20-30 volts if they're like most welders and since he's got his hand on the giant grounded steel block and maybe barely touching the wet rag that's touching the electrode, it'll ignore him for the most part. Maybe a tingle if he sticks his finger across the electrode-work gap RIGHT where it goes into the hole, but then you're risking getting torched by slag spatter more than electrocution.

spog posted:Can you then use the hole as is, or do you need to retap it for a larger bolt? I think the point is to remove the broken tap without touching the sides at all. So ideally, you would just finish tapping with the same size tap, and you're good to go.

He said he picks the remains bits of the tap out, and disintegrates a hole slightly smaller than the tap.

It looks like there is slight thread damage (little dings and dents in the crests of the threads, he chases the already tapped part with a tap so there won't be interference, just a lower class thread fit) from knocking the tap remnants out with a chisel but I wouldn't hesistate to finish tapping the hole with a new tap of the same size and forget it ever happened.

I wasn't sure if the aim of the game was to remove the hard tap material, so the hole could be retapped; or just clean out the hole so the existing threads can be used.
|
# ? Jun 3, 2016 16:54 |

I'm sure the customer would appreciate if there was zero damage and the original threads could be used, but I imagine the reality is that's not often going to work out, especially if the meathead who hosed up the tap spent any effort digging at the broken bit trying to recover it on their own.

I'm going to guess the barriers need to be raised up some. I'm assuming the trucked rolled over the barrier from the other direction. Similar thing happened here in cincinnati recently. However, the person in the car was killed sadly. Basically, some pile up happened on the bridge that included a semi in the rear. This semi ended up plowing into a car, pushing it over the barrier and into the ohio river. And it doesn't seem they have any interest in raising the height on the barrier either. Just going "welp, that was a one in a million.."

cursedshitbox posted:You can't just post this without the story: It's better than just using the welded-together wheels as a jackstand... quote:Turner placed an improvised metal stand beneath the rear of the truck bed in order to lever the truck's rear wheels off the ground with the hydraulic hoist cylinder as the bed raised. When Turner had achieved enough clearance to facilitate the work, he crawled under the truck, positioned himself between the rear axle of the truck and metal stand and started to make adjustments to the right rear brake chamber. The truck either rolled or slipped off the stand pinching him between the stand and the rear truck axle, causing crushing injuries to his chest. Is this normal service procedure for dump trucks?

The trucking thread would probably know more, but usually the best way to handle "I'm a truck driver and I own my own truck" is to incorporate and have an accountant take care of the actual company, then get contracts as the company. For example one of my neighbors "owns" a trucking firm, except he and his daughter are the only employees and 100% of their business comes from a construction materials company that contracts him to deliver truckloads of plywood, roofing shingles, etc to large jobsites. As I understand it, it's a fairly common way to do owner/operator trucking businesses.

That's how it's done here too, often trucks will be painted in corporate colours but have 'John Smith Trucking Co' written on them somewhere.

It skirts having to pay income tax on buying stuff for her too (and just in general) - as an employee she can just be given a company chargecard (company buys things) rather than being paid a salary then having to use that to buy stuff, and her "salary" can be $1 less than what you'd have to pay income tax on - it's a fairly common thing to do for small businesses like this in at least. If nothing else it would let company profit be split between two peoples' tax returns which would result in a lower net tax rate than if one person was paid all of the profits. A number of my high school friends were technically employed by the family business from the moment it became legal (15yo give or take) and "paid" a "salary" of $1 less than the tax-free threshold per year so their parents could dodge income tax on that amount (appx $30k/year, which is a lot when you consider our peak marginal tax rate of 49%) until they got an actual job. Yay, tax fuckery!
