Re: 1911 Project

I had an hour to tinker so I dug out the rotary table and set it up to where the spindle and table were coaxial. https://i.imgur.com/muUMn0nl.jpg Then zero'd the thumb safety hole in the frame to the spindle/table axis using a test indicator. https://i.imgur.com/WHucEydl.jpg Dialed in the offset and...

1911 Project

I decided to try building a 1911 lower receiver when I overheard someone say that Foster had them on sale for $125.00 form $250.00. First was to measure it a bit and find that the sides of the frame are basically parallel with the exception of a raised area on the right side where the roll mark and ...

Re: Vertical Band Saw: Useful?

Russ's vertical is the same as mine above. I've had mine since the late 1970's and it just runs and runs, although I did replace the motor earlier this year. One of the best things I've ever bought.

Re: Dorian

I've got Jim Cantore here where I am with his swim goggles on trying to make it look like something is happening when we've only had 35 mph gusts and light rain. I think someone must be spraying him with a big fan and a hose. He and these other local news reporters are pathetic...

Re: Which end mill to use

The coating on your end mill, (TiCN) isn't particularly desirable for aluminum. Aluminum tends to adhere to Titanium Nitride coatings. Zirconium Nitride (ZrN) would be a better choice if you need a coating, but even then, it works best at very high speeds.

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.
