Re: Which end mill to use

What are the advantages of three flutes vs two or four? Polished TC fast helix 3 flutes are pretty much optimum for ally cutting if your machine has the speed, feed and rigidity to use them, more flutes than 2 allows faster feeds and they don't gum up like a 4 flute will if you run optimum speeds. ...

Re: Which end mill to use

3 flute, HSS, (not too common) or ZrN coated carbide.

Run it as fast as your spindle will allow.

Spritzing with a spray bottle of soluble coolant will do wonders.

Re: Modems and extortion

But, I've lived all over the country and found that regardless of the name on their letterhead, they all approach troubleshooting much the same way. I'm pretty sure they all have a support diagnostic flow chart for tech support that goes through a list of simple to check issues, which if not resolv...

Re: Threading

However, regarding chipping, that's not at all guaranteed with a slight mistake in timing. I'm not at all sure about other options as I haven't tried them. My first indexed threading tool happened to be a #3 Top Notch that I found left on a scrapped lathe (of all things). Got it for (IIRC) $0.15/lb...

Re: Gear Cutting

It's all about the grain in the phenolic laminate.

I had to make a batch of hydraulic pistons from phenolic and it would have been simple to part them off of phenolic rod, but I had to cut plugs from sheet using a hole saw to make then from to get the required strength due to the grain.

These pics have helped the investigation. I thought it looked to be dropped face first. It looks differently now.
It's now broken in two different directions. :?

I'm not familiar with these terms. What is this "rust" and "humidity" you guys are speaking of?

I copied this from another forum when I Googled "Keystone 122": I contacted Keystone Lubricants re the mysterious, unavailable Keystone 122 specified for Gorton mills. Keystone is now part of Total (the French oil and lubricants company) KEYSTONELUBRICANTS.COM The reply I got from Total USA reads "T...

Re: Bare Metal Protection

Any idea of the age of the one shown?
No idea, but I remember it being in a friends shop in the early '80's. It was then traded to another friend that traded it to me.
