swarf

Put shaft in freezer for 2 hours . Use heat gun to warm the bearing. Place the shaft into the bearing while the bearing is hot. I do...

Try setting your compound slide over 5.7 deg, this gives you a ratio of 10 to 1 so you can machine tenths. And if you polish your...

Most of us don't hold that against you. In fact, I believe that most of us admire your attitude. In ALL learning, it should be FUN...

Personally, I think it's not because of the surface If the surface is rough, when measuring, we will also measure those high points I...

Just for the record. I'm no machinist, nor do I wish to be one. I take perfectly good material and turn it to swarf. Im just a hack...

When I started seriously machining in about 2009, the thing that held me back initially was impatience. I expected to take a few cuts...

How and what are you using to accurately measure the bore? Having to go .003" -.004" under size on the shaft means something sure isn't...

So it's a bush, not a ball bearing as everyone assumes. 1.5 thou is a LOT of clearance (I'd say sloppy fit) for any ball bearing. Not...

Ah, the famous "tighten the screw till it strips then back it off ¼ turn" approach ☺️😉

It takes time to get a good bearing fit. I first time I was doing bearing fit For errors I use Loctite for ball bearing fit and made...

Then that's your issue, without an accurate measurement for bore size then it's pretty tough to come up with a shaft size that will fit...

Pete has the answer. Take heed. Surface finish is really like the cutting edge of a Hacksaw blade. For a bearing, you need to Linish the...

Yep calipers. I have telescoping gauges but have never used them. Might be a good time to start using.

It's a plain bearing block made from bronze. Drilled and bored to size. I machined a shaft for it (surface finish a little course) to...

As I have not really much professional experience in working to close tolerances my strategy is to cut the last about five steps to...
