These arrived today. Not sure what I'm going to do with the diamond polishing compound but I had watched a video where a guy used it and thought it might come in handy.

I use the diamond paste on my home made lapping machine for putting a mirror finish on scraper blades. Even better, Tom Lipton made me a believer in the aluminum foil lapping method a few years ago. No joke, it works. Skip ahead to 24:47

Not a delivery but a purchase from Harbor Freight. I've seen this tap wrench in a number of YouTube videos and wondered what brand it was. Turns out to be a ratcheting tap wrench from Harbor Freight. I need another tap wrench like I need another hole in my head but I was curious so I bought one today while I was at HF. Very impressed with the quality. It's made in Taiwan. I can see it being useful on the mini-lathe so I don't have to constantly change the position of the handle in order to rotate the wrench. The only problem is that the end where a tap guide would fit in has a set screw so I'll need to fix that. For $19 I think it was worth it.

I actually went in the other direction.
I have several ratcheting tap handles. Had to manually tap several holes. Started with the ratchet handle and quickly discovered that I could not back up the tap to break the chips. Went back to the toolbox for the non-ratcheting style. The ratcheting style seems to work fine in the lathe, mill or drill press with a screw tap and lots of lube but for this occasion and a hand tap I had to go old-school.

Although you can switch the direction of the ratchet mechanism so I'm not sure I'm following you. I'm sure I'm overlooking something obvious.  Ed P.S. Never mind. I see what you're saying. I've never used a ratcheting type tap wrench before so I plead ignorance.

Yeah.
It was not "I couldn't switch the ratchet" but "turn tap 1/2 turn, switch ratchet, break chips, switch ratchet, turn tap ..." was a PITA. "Turn tap 1/2 turn, break chips, turn tap ..." was much less of a hassle. As mentioned, that was for a manual tap where breaking the chips by backing up the tap appears to be a "requirement" to not break the tap. When I do use the ratchet handle, or the Tapmatic, or even resort to a drill, I use screw taps which appear to be designed to clear chips while going in one direction. Thanks given by: EdK

I bought one of the HF wrenches about a year ago. The ratchet selector ring has a center position that locks the ratchet so you can also use it as a 'standard' tap wrench handle. What I like about it, is that it is a beefy tap wrench and with the handles extended out gives lots of leverage for larger taps. The only caveat is, it feels like the ratchet mechanism will break before a large tap would. Don't know if that is good or bad but at least it has a lifetime warranty.

Ed and Willie ... I hope you are proud of yourselves. Now I have to go get one to replace my General Tools handle. Thanks
