Very interesting. I could have done without some of the attempts at humor, but it was informative.

That's super!
FWIW, in the way back I ran a honing machine and I was situated between a traditional hydraulic broach and a hob machine center for mining machine parts. The broach guy and I were the same skill pay grade. The hob guy was about five levels above us.

Excellent videos. Very informative. I really like his low-key, light hearted approach to it as well. He makes it fun to watch.

That was very cool. Thanks for sharing.
I must not have watched close enough, because I still don’t understand how you can form a hex doing that. The stock was turning, but was the broach tool turning as well? Are they both turning and the tool kind of wallering it’s way in? |

Yes and Yes. The cutting broach tool was wallering around the same as on the mill, but while on the lathe was also rotating at the same speed of the material.

Go back and watch where he walks the hand chisel side to side to aid in cutting the wood. That's how the broach works it's way through the material.

One of Tony's older videos talking about Oxy Acetylene.
Once again he breaks it down so the average Joe can understand it. (I still have a full set minus the bottles but I haven't used it in over a decade.)

Another excellent video by Tony... It's interesting that Western Made tools now need reworking. That's one of the effects Chinese made tool has had. Everything comes down to cost. It wasn't always like this and older US manufactured Starrett tools are a great example. Since off shoring some of their manufacturing their standards have slipped a little.
Having said that would you bother reworking bore gauges? I'm not sure I would. ... But reworking cheap Chinese made tools can have mixed results at best. The really good stuff from China is comparable in cost & quality to anything made in The West but they can be difficult to find... So why even consider them? I don't have anything Chinese/Taiwanese made. All of my measuring tools are either US, UK or Australian made and most of them I bought second hand. (7 minute video)

I watched the bore gauge video. This is an example of exactly the kind of thing I do all the time - and I know I'm not alone.
• Start with a cheap tool or product that I fuss and fight with for a few years. • Make the decision to research and buy a better quality "thing" to make my life better. • Be disappointed in the quality of the thing • Fix it to try (or try and fix it*) to have what I was hoping to own by stepping up to quality. (*This last step can go one of two ways, use your imagination.) Tot used some cruddy bore gauges for years, decided to update, probably looked at Starrett and settled on "second best" B&S. Couldn't believe the crunchiness of the brand new precision tools. Used his considerable skill and talent to improve things. I'm glad he posted that video. B&S (and anybody else) need to be called out for selling crap that needs consumer R&D in order to function at the expected standards....

Have you ever wondered how clutch packs work?
I'm about to upgrage the clutch on my 78 SC and this magically appeared on YouTube. Serendipity or are they spying on me? I'm going with serendipity. ![]()
