Crows Foot Spanner

Anyone got experience of these. They look good for access issues. But I just can’t get my turnip around how they actually turn a nut!

so you attach your wrench via your 3/8 bar, then I can only assume some odd feeling rotation happens to ensure the nut tightens?

so if you think your 3/8 bar is rotating, but this rotating axis fits into the bottom of the open ended crows foot - not how you’d normally rotate a nut. Mashing my melon

 

If you imagine it with a t bar instead of a ratchet it works the same as a normal spanner just with an extension in the middle

 

If you think that's difficult, you should try using one of these!

 

That’s nasty

 

But the only way to get kitchen sink taps to undo ,,, they are really simple and easy to use

 

That's why plumbers, sorry heating engineers, are paid such extortionate amounts of money!

 

They are a bit weird, as the Turning Thing is off-centre. Serve a purpose, tho’

 

I’m thinking the close up bolt on my starter. There is one side side I reckon will let access to one of these

 

I hardly ever use mine. You may find the jaw bit is too thick/chunky to do anything useful.

 

I have 13, 15 and 17mm sockets that I have ground down the outer circumference for tight spaces like this.

 

Its a heck of a lot easier with the engine out and just the gearbox hanging there.

And although it might seem inaccessible, if you are lying under the bus with your feet out the back, its quite easy to reach that bottom nut.

I was there today - put the starter motor back in, then the engine then realised I had put the wrong bolt in the gearbox hanger above the starter so I had to reach the gearbox hanger nut over the top of the starter .
All that time, the nut and stud was clearly visible in front of my face.

Then I put the heater concertina back in and it then got less visible .

 

Yeah they are great if its a monoblock but not taps lol

 

If you have to ask what they do you don't need one - FACT

I’ve got very limited access to a starter motor nut. I’d almost need a quarter length spanner. So this may do the job. This is only reason I’m asking

 

In general, the answer usually isn't "buy a gadget". You'll normally end up with piles of unusable carp and still have a loose nut with that approach. Far better to adapt something you already have IMO as you can hack something up until it fits - you'll be a proper fitter then too, it used to be a profession.

 

Especially with a small corner sink in a vanity unit where the copper pipes and waste pipe and pop up mechanism all conspire to obstruct every possible means of access to the nut which is encrusted in scale and tightened by Geoff Capes 20 years ago!

 

What are you trying to do up?
