What Did You Buy Today?

I got a set of expanding mandrels covering about a half inch to an inch. They are very well made. What I like about this style is that the area under the work being held all expands, rather than just pressing the workpiece onto a simple taper. Seems like this will keep the work aligned better, and make it easier to position on the mandrel. The cost seemed good, I recall maybe $80. Edit: I mean $100.

Are you talking the end that goes into your tailstock? I had a couple live centers that never auto ejected because the overall lengths of them were too short so I made some custom end plugs for them. Much nicer to use.

These look nice!

Part is made in Japan. Metric thread and cannot do Metric on our lathes.

Local distributor supplies everyone in hardware should have an assortment of right size bolts, will modify one to fit as a plug for the tailstock end.

Those are a nice item. I could have these recently when I converted my lathe compound graduated dial over to a large dial. The replacement part I got needed some fine passes to clean up the faces but it wasn't easy to hold. I cut a slight taper on some stock, press fit it and it worked but just barely. Some precision would have been very welcome because I didn't want to remove the graduations. It was delicate work, would have been easier with these.

HA! I haven't needed a metric thread.....yet! That is going to really bother me if I need one and can't do it on my lathe!
 
I bought myself some engraving fonts for the engraver kit in picking up this weekend. They are New Hermes 35-302.
