Electric pit gun?

Explain why the largest tire retailers in the nation aren’t using electric lug guns.

One of the reasons, as I see it, is the fact that the superstructure of those corp tire shops, scattered all over the place, are set up with huge compressors with all work stations plumbed into the system, plus probably, don't know for sure, they buy pneumatic guns in bulk and have wholesale contracts to purchase in quantity with good repair and replacement service. You have a very efficient compressor that is pumping free air (so far) and multiple bullet proof guns and pneumatic equipment to utilize it.

IMHO, that is a no brainer for sure.

Just a little foot note: The process to make batteries is an environmental nightmare, do some research and you will see. Just the mining and separation of material to make these new hybrid batteries is awful. Then you have the , WTF we gonna do with the old used up bad batteries that are hazardous waste?
The reason for the push to electric everything is, "follow the Money". Has diddly to do with carbon BS.
 
I have to agree with batteries not being all to great for the environment no in nascar can say they really care all too much about the environment given the amount of fuel and tire they go through on a given weekend

For those that think single lug wheels are so great, ask Graham Rahal, or better yet, ask Conor Daly, who's race today was ruined by Rahal's errant wheel. When's the last time a Cup car had a wheel fall off (not torn off) anywhere but pit road? It's a not all that uncommon occurance in series that use single lug wheels.

In the garage area we put the wheels on with an battery operated impact, then lower the car and torque every lug nut. There's a reason for that.

I don't remember the exact details of that accident, but my guess is the team and likely Dale Jr KNEW that wheel was barely on and were just hoping it would make a GWC finish. I don't think Rahal had a clue anything was wrong.

Garage situation and pit road race situation are like night and day.

In NASCAR that is true. In Drag racing the garage situation is exactly like the pit situation at the track. We back the haulers inside the shop and work on the car right next to the hauler with the same tools we use at the track. The only difference is we don't have to put an awning up or do a complete rebuild in less then an hour...unless we are practicing. :)

I see’d the track ordeal at Pomona. It’s pretty cool.

The point was a battery operated impact doesnt create enough torque to properly tighten the wheel.

Wait what? I'll let you argue it's not fast enough all day long, but they provide more than enough torque.

I can't speak for what materials and diameters they're using for a wheel stud but recommend torque for a 3/4" grade 8 bolt is roughly 375 ft/lbs.

I have a few year old Milwaukee 1/2" impact that will max out tighting torque at 700 ft/lbs (and I know technology has improved since then). Now its pretty hard to find a 1/2" torque wrench that will exceed 250 ft/lbs without using a multiplier, so I find it hard to believe that teams are tightening lugs in excess of 750 ft/lbs. My guess is they're setting them to a specific torque setting on an electric gun and double checking them with a torque wrench. Same thing that any good mechanic does when installing a wheel on a passenger car using air or electric.

When a new crew member that has never worked on a race car is hired they are usually put on cleaning parts detail and then changing tires. If I train them to change tires I always emphasize how important it is to torque the wheels after installing them with any impact electric or air. Another thing I emphasize is that if they put a nut or bolt on they don't leave until they tighten it...and if for any reason they can't tighten it then label a piece of tape and put over the bolt or nut and let the car chief know.

They arent reliable and not trusted so we torque them and dont use them on pit road.
 
The Bowman/Ally commercial during this weeks race showed a crew member tightening lug nuts. A battery impact was being used.
 
When they build an electric drill motor strong enough to power the toys in the videos at a satisfactory rate you will know they have arrived.

Until then they will have to be pneumatically powered or driven by a hopped up two cycle engine.

The guys in the pits for SRX changed a flat in the race at Stafford with one. Wheel didn't fall off........

I wonder why the entire Cup garage doesnt want to use them? Or xfinity, or trucks? hmmmmmmm
 
How it would or could translate to pit crews i don't know but I've got a 3/4" high torque cordless Milwaukee like in the link below that I carry in my semi truck and use all the time. I haven't seen anything yet it couldn't bust loose. No problems torqing anything down either. Now this is just occasional use on my truck so not a fleet shop situation. I think it's great for my own tire work. Way better than lugging around that big 1" impact. I know other one truck guys that carry the 1/2" version in their sidebox and tell me it will bust loose anything on a semi truck no problem, including the lug nuts.

 
I love playing this game but im done. Here is your answer why we dont use battery powered guns...... SPEED!!!. Good night.
 
Speed was already thrown out the window when we went to a standard pit gun. If you make everything standard you could send guys over the wall with "standard" 4 way lug wrenches I guess. Now talk about painfully slow
