Do you see that rabbit-hole opening beneath your feet?

I thought the exact same thing, the year was 1970.

Harry taught us to use center drills. Fred reinforced that lesson. I never heard of a spotting drill before joining these internet fora. They were cheap, so I bought an assortment of sizes just to see what all the buzz was about. I guess I'm lazy, I still just use a stub drill...

I have several milling cutters that use the APKT1135 inserts, starting at 10mm and up to 30mm. They get used a lot, especially the 20 and 25 mm. I also have a 40mm that uses the APKT1604 inserts, but by the time I get to that size I prefer to use my 50mm facemill that uses the SEKT/SEHT inserts...

Yep. I really like my 2 in. facemill that uses the SEHT/SEKT inserts. It will really move some metal and leaves a very good finish. It will take .100 DOC, but if I'm looking for an excellent finish, I still use a fly-cutter.

I magnified the picture and it is a very fine tooth cold-saw blade. Smokin' deal if you have the need or desire. I made my bones on a Brobo 350 with dual air vises. Broke a few blades (3 to be exact) learning the ins and outs. I didn't tell Fred about the third one until I had the money to pay...

Quick and easy expanding collet stop I needed a second collet stop recently. A quick survey of my 5c collets revealed that very few of them were internally threaded. Expanding collet stops are expensive (and I'm cheap), so I just made one.
