You do not need to buy one, is just a tube you drop a steel ball, the higher the bounce the harder the piece.

It's not like such a mistake would destroy a Mars probe...

Never happened before.... they built the pyramids.

Are we sure we are not confusing Celsius with Fahrenheit?

I agree with Russ about 600C taking most of the hardness out. Small parts that need no soaking can be tempered by color. Polish to show bright metal + heat with torch on the side that you want less hard + look for the color to travel from the torch side to the tip + quench when the color you want re...

Banggood's search on their website is awful. Is not just Banggood, there are many companies that do not understand the issue. Parts that are mostly characterize by dimensions need to have a dimension selector. I do not want to look 97 pages of randomized ball bearings or gears to find the one I nee...

Locked Chuck, Tool on the tool post ... in and out advancing the cross slide a couple of thousand at the time. I...

John, I do not see any source where a double cost less than a single. A double cost usually less that TWO single.

I asked the same a while back and the "village" opinion was negative due to the fact that as the collet sucks up the tool it may ruin the other end. I use them because they cost less than two singles and by using 2 cents worth of care there is no problem. There is a substantial difference of attitud...
