How to's / Re: Circlip groove
« Last post by BillTodd on March 19, 2024, 03:51:29 PM »
I found a used carbide grooving insert 0.75mm by my measurement.  Might have one good edge, or would sharpen on a diamond lap.

Pm your address and I'll pop in the post

Just wish the silver steel wasn’t so hard!

Sounds like a good approach to getting it sorted.

Steel is not hardened…

I’m thinking using a broken 1/8” centre drill suitably profiled to make the groove, sharpened on my t and c grinder..

Grinding bits of Eclipse hacksaw blade, just below the teeth, if you have something that can hold it like a parting blade.  Otherwise sacrifice a small HSS drill bit in some metal stock you can hold in a toolpost. Your dodgy Dremel can part profile it, do you have diamond stones for finishing ?  Keep stick out to a minimum unless you have a pile of small drills to use.


Oh !!!  Is your silver steel part unhardened ?

How to's / Circlip groove
« Last post by John Rudd on March 19, 2024, 10:47:38 AM »
I need to machine a circlip groove in a 3mm silver steel shaft for some circlips.

Circlips themselves are 0.6-0.7mm thick and are 2.3mm.

So to the collective, I put it to you, what’s the best way to tackle this?

I tried an abrasive disc ( my fav method.) in my Dremellookalike but the end brg is knackered so it wobbles like a jelly….I tried Stew Harts method using a slit saw….hmmmm some erroneous noises made me abandon that idea…

Silver steel doesn’t machine like EN1a sadly….so open to suggestions please….

What works for you?

Finally some real pictures, I have done the guide thing bit and I am sure that rigidity will not be an issue on this at least.

Well after a couple of weeks of nocturnal jungle drums from the A12.  I just spent a week possessed by a demon...

After four days standing on my neck, it got bored and chose to move to my ears and scream as loud as it could. And, just to make things fun , it kept moving the ground beneath my feet if I tried to stand , occasionally throwing me against walls .   

Luckily, it seems to have taken a shine to my neighbour, and has now left me alone... I hope.

A couple of pictures of your knurling tool in situe, showing alignment and one with a bit of stock between knurls before knurling.
