Using a impact driver to install spark plugs

No issue, he did a good job. When running down the impact was free spinning which shows the threads are fine. He stopped the tool once it impacted. The tool makes very little torque before the impacting starts. Following up he gave them a light snug with a ratchet. They shouldn't really turn much. To get from seated to spec is like a couple degree.
 
There's an automotive tech who was replacing spark plugs in a Ford Explorer. Instead of torqueing the spark plugs the spec, he drives them home with an impact driver so hard, he couldn't budge them with a ratchet. I want to know what's your opinion about him.
so a video from a guy with 25 followers and you clearly are seeing something that I am not.
is it best practice.. probably not but I don't see anything troubling.
 
To be fair, most successful independent shops are flat-rate. It is really the only way you can attract and compensate high producing technicians.
Never heard of a shop that wasn't flat rate. Is that a thing somewhere?
The shops I use recently, are 2-3 bay father and son operations, plus another fellow, or an apprentice. Small town shops with their names on building and the owner is turning wrenches. They aren't wrecking themselves, and cutting corners, trying to jam through as many cars as they can in a day and beat the clock, or charging the so much that they don't have a long waiting list. They are doing it because they like fixing stuff, and charge enough to have a few toys and nice vacation.
You can watch through the open shop door if you like, and they sure aren't slow, and they charge a fair price.
They do undercoating, and I listened to him tell a customer on the phone, to drop off the car this afternoon, they will pressure wash the underside, and then leave it in the shop to dry, so they can spray it in the morning. So they seem to want to do the right thing for to keep their long term customers.

I guess with little overhead, they can charge 8-10hr each a day, and go home with most of it, so its certainly working for them, and for me. No dealership fees, franchise, advertising, website, mortgage, etc.... No free coffee, but you can look at his collection of old interesting mechanical stuff for free!
4.9 of 5 google reviews too, so its not just me who like their operation!
 
I believe an experienced mechanic could modulate a power ratchet on low setting, etc. But I would not do such a thing.
I remember my brother using his air ratchet installing plugs in Toyota/Honda aluminum heads; he had the touch with that thing. His shop was well respected; comebacks were rare!

If it works for them. There are plenty of good shops that charge flat rate. I think thats the whole point of flat rate - no surprises, customer pays a fair price, shop charges a usual and customary amount. If something else comes up along the way its a change order.

Do you sign a work order - or the bill is a surprise every time?

I looked up the Milwaukee impact driver; it's rated for 125 ft lbs or 1500 in lbs.

The impact driver doesn't have low setting, just forwards and backwards.

You can hear in the video it is just running without actually impacting (free spin). To get 125 ft lbs you would have to let it impact for like 30 seconds. A couple ugga duggas is nothing.

Do you even wrench bro?! 😁

Just giving you a hard time, but do a couple jobs with a impact and it will be obvious the difference.

Unless they cater to a very specific audience, the type of shop you just described are non-existent around here. Or in a lot of major metropolitan areas. Those shops are definitely a dying breed. Most successful, all makes independents we have are similar to this: https://www.yelp.com/biz/orinda-motors-orinda-3

They mimic a dealership type experience because it attracts the same types of customers -- those are willing to invest into their cars. 10-15 bays, plus all of the amenities.
