Todays Project - What did you do today?

Good job Mike. FYI, the original finish is not from a milling cutter, rather its from a vertical spindle rotary table segmented wheel surface grinder, often referred to as the most popular brand, a Blanchard grinder.

Interesting. Thanks for the info. Not a very nice finish.

Nice fix on the drill press table Mike.

One of the guys I work with got some solid aluminum 40mm practice grenades that we shoot from the MK19 belt fed grenade launcher (if you haven't witnessed this awesomeness, you need to!) and wanted to make shot glasses out of them. His original idea was to just use a drill bit. Well when you want a 1.25" hole for a shot it doesn't make much sense to use a drill bit. I told him my lathe was set up and he asked me if we could do it. My response, "the lathe is capable, I have no idea what I'm doing with it. Let's give it a shot!" So he brought them over and we started making some chips last night. I actually used the back gear to push the 15/32 drill bit into the piece. Probably not the best idea but it was fun. Teaching yourself how to use a boring bar is kind of interesting. Then I used some mild rolled steel to make specialty cutters with the HF grinder I bought last night after work. This is the final product and I hope you guys enjoy the pics! I will be making some more today so I will take additional pics!

I also told him that I don't recommend drinking out of them and that they should be sealed with something before he does if he is going to. Also plan on cleaning up the tooling marks with a Dremel tool.

Thanks for the flashback Ken.

I spent many hours running a pair of Blachard grinders, squaring up stock for a form tool company. It was probably the most boring job I ever had except when there was a power fluxuation and the electric rotary chuck released the hundreds of parts it was holding. That why those machines always have dents in the guards.

Nice job Paul.

I have one of those forgings sitting around waiting for some machine time. The company that makes them is a half hour drive from me, Brass Aluminum Forging Enterprises and I've heard that they will sell to individuals in small quantities for $16 a part. Of course I heard it on the internet so it must be true.

They also make the upper and handle forgings.

Good advice. No way would I drink out of, or cook in, an aluminum (aluminium) vessel. Instant Alzheimers.
