The Metalworking Thread

I forgot to take a picture of the milled hex.

I Googled annealing, it is a similar process.

I will settle with both of us being right!

I haven't tempered at a fixed temperature, but I have applied heat to draw back a quenched part, which is a form of tempering. Heating it relatively gently will draw it back to blue, and then to a straw color. It's still hard, but not as brittle.

To work on a hardened part, I'll heat it red, and then let it cool, which anneals the metal, making it soft enough to work. After that process it would need to be heated red and quenched again.

My understanding (which might be way off) is that for tempering, the temperature of the metal never gets hot enough to make it red, but for annealing, it has to.

The former is a problem for me, because my brain doesn't seem to register metal as too hot to touch unless it is glowing...

That is some pretty work!

That is some pretty work!

Thank You very much!

A fair amount of time, effort & $$$ went into making them.

I have made 5 different clutch removal tools, 3 for Husqvarna and 2 for Dolmar/Makita.

A much better result than the sockets that I have hacked up with my angle-grinder!

My version
Find an old socket with the right outside diameter weld on two or three rods of the right diameter

 

[Partner]

And after welding, harden it a bit by cooling it in liquid

Many ways to make a custom tool.

If it works, it's good!

I found one and ground out what was in the way. Maybe an IMPACT socket would work as well. That was for a 3 shoe. It hasn't broke 'cuz I bought one and use it now.

My custom made ones are challenging Solid-Carbide end mills, and clamping vices.



I had to swap out the broken mill bit and redo this one.

Wish I had the tools and skilz to do stuff like that.

It is fun to tinker up something of Your own.
And it feels very satisfying when it comes out the way You envisioned it.

Same here...

I agree I live my life doing that
These are made of metal and I salvaged them to build a shop out of them.

Footings are done next year they will be sitting on them and reroofed

Someone will probably ask what this metal is for

This wasn't funny.

Called it quits after the fourth 7.0mm end mill committed suicide.

It is a proven milling program, I used it over a dozen times with no issues regarding tooling choice, feeds & speeds.

Come to think of it, maybe I had a bad collet causing out of round.

P.S./Edit:
A 10.0mm end mill processed the top & ID, no issues.
