DIY O2 sensor tool with a question

I work at a sheet metal shop, and can fabricate a basic 22mm closed end wrench easily enoughaw, so no need to buy the $30-40 specialty sockets...

My question is, how much room is there to turn/swing a wrench? The longer I make it, the more leverage I get...but too long, and there's no room to turn it...

Anyone have a suggestion?

Can you just put some knurling or flats on it, so you could grip it with almost anything?

Maybe make it fatter (larger dia) instead of longer???

This one is appears to be 10" long and cost 10 bucks. I paid less than $10 at Harbor Freight for just a socket.


Here is a socket for $7 with free shipping.

Dead link, thanks tho...I know I can get them cheaper online...however, it's still more expensive than free, plus the vehicle is my daily driver/only transportation, so if I can make something to suit now, rather than wait a week for something to be shipped...well...the choice is obvious

I'll use the 10" handle length suggestion tho 😉

Just takes a couple seconds to load, very odd.

Could you do a variation of this tool?

This was cut with a water jet for me at work from 1/2” plate.
It’s used to remove the inner tie end from a rack and pinion steering gear while the rack remains in the vehicle.

I just replaced the two O2 sensors on my 97. I had purchased the tool before the project but sprayed both sensors with Kroil the weekend before, in the middle of the week and the night before the project. I took both sensors off with a standard wrench without much effort. I live in the rust belt and thought it’d be worse.

@k0m0d067 nice work on the wrench.

While we are on the 02 sensor subject, I’ve posted this old school tool before.

It’s a spark plug thread chaser. If you have a problem threading in the new sensor this tool will be a big help.

I will admit, many times in my career, if I knew I was installing a new 02 sensor, I would cut off the wiring pig tail and use a 1/2 drive deep socket or a box wrench to remove the old sensor. Maybe not recommended but quick and effective when the old sensor is toast.
