What did you make with your lathe/mill today?

Then the boring bar holder goes here.

This is how I do it. The bars have flat surfaces on top and bottom.

I think my holders are 250-301(?). Screws aren't long enough.

Looking for a Lathe/Mill project. While flying yesterday I decided to modify the gas cap on the Champ. When I made the cap didn't have a straight knurling tool so I used the diamond shaped tool.

. Found a few on the web from Harfington. Never bought from them before. Bought 1mm and 1 1/2mm pith with holder for $15.47 each. Will see how they work

I good flying friend of mine is also into trains, he likes old Lionel and Marx trains. He always comes up with a project for me. The last one was tapping 4-40 holes in an old engine. Took about 3 minutes but he was as happy as could be. When he was here last I showed him the prototype gear I made for Steven. So he calls early in the week and says can you make me a gear? I don't know sent me a picture. He sends me these photos. He brought the pump car over yesterday so that I could measure things up. Looks to be 16 teeth per inch left hand pitch. I ordered 6" piece of 3/4" SAE 360 brass from McMaster-Carr, should be here today.

After 3 prototypes finally have a possible workable gear. He coming over tomorrow with the pump car for a test fit.
