Very Small Hook Spanners

[Brad93]

I need a pair of very small hook spanners for my Alexander grinder.

I have one that kind of does the job but it's actually a little too small.

Id say the slotted rings they need to work on are 12-15mm in diameter.
Here's a picture of the deckel ones.

Oh and the wrenches can be no thicker than 4-5mm as that's about the thickness of the two nuts

you need a plasma cutter

Someone with cnc plasma......and a bit of thin plate.....

Doubleboost???

Plasma won't have the definition

Cromwell tools list/sell hook/pin spanners

Zoro or rs?

Waterjet should have good clean edges at that size

 

[Munkul]

As if you can't finesse a bit of metal into the right shape with plasma/grinder

Plasma?
do you not have a file.....3-4mm thick, and 12mm diameter, wee bit of flatbar, probably about 10 minutes work there.... you'd have almost finished it, by the time you've read the replies here...

12mm hole drilled for the main radius then weld a drill bit for the pin

I couldn't find any either, though I didn't look very hard.

I used my Christmas cracker Knipex in the end.

I think they are DIN 1810.

See: https://www.drabbe.nl/static/uploads/pictures/original/datasheets/EN/DIN 1810.pdf

It looks like 16mm dia. is the minimum there.

Wixroyd sell the 12-14mm size:

Maybe look at ER collet nut spanners. If there is one the correct dia., file off three of the prongs.

The idea is good, but I am fresh out of rectangular drill bits.

Square ones work just as well

Gedore do some decent hook wrenches, smallest is 16mm, thickness is 3.8mm. Part no. is 40Z16-18. Prime Tools may be able to help.

Could try a local bearing supplier, may stock the SKF c hook spanners.

 

[Brad93]

Im going with the SKF spanners

I'm going with the SKF spanners

The SKF spanners, here: https://www.skf.com/uk/products/mai...smounting/bearing-fitting-tools/hook-spanners do not meet the specifications of the original post (i.e. 12-15mm diameter).

 

[Ubique]

They're also hook, I thought you wanted pin?

Always called them c-spanners.

Id plasma cut and file them.
