Tried my hand at turning aluminum on the wood lathe. It was surprisingly easy to turn with an old carbide tip I had. I've honestly turned some woods that were harder lol. The biggest issue was drilling it out on the lathe, the bit kept packing full. Other than that it wasn't bad.

With aluminum you have to retract and clean the bit fairly often. . Otherwise the shards pack up.

Nice pen !!

Yeah, it's really odd. The first 1/2 inch will cut beautifully with long stands coming off, then the rest just bunches up after that. I even tried going from smaller bits to larger and still had the same problem.

The aluminum chips/ribbons are breaking as the bit goes deeper and are being pushed along the drill bit flutes. When you first start they peel off from the tip into the air in longer ribbons. Also, unlike wood they don't compress like saw dust when drilling requiring more frequent clearing. VERY NICE PEN by the way.

A good cutting fluid will also Help. WD40 works pretty well for aluminum. Also occasionally check the tip of your drill bit for stuck aluminum. Keep the cutting edge clean by knocking off the stuck bits of aluminum. The cutting fluid will reduce this somewhat.

Kyle do you know what Aluminum alloy you used? Anyone else have a better experience with turning one alloy over another?

I was using 6061 Aluminum, I bought the first rod which was like 3 feet long at Ace Hardware for around $10. That is what I used for the pen. I ordered a thicker piece from Amazon that is about 8 inches long. I've yet to turn it though.
