>I use the rounded over corner or edge of a small anvil. My usual one is a hunk of 4" round shaft scrap (unhardened) - I just rounded over the edge a bit. Tool stores sell little sections of railroad rail modified to serve as a combination tapping anvil, (saw or whatever) straightening anvil, and saw setting anvil. Pretty handy! The key is to hit the soft steel not too close to the lamination line and not to do too much tapping in any one place. Go slow and check your progress frequently. I was taught to use the rounded edge/corner rather than the anvil top because it allows one to only contact the anvil right under where you are tapping. The toolmakers themselves seem to use the anvil top near a rolled over edge and use a bigger hammer. Use a hammer you can control very well - whatever size that works out to be.

God was I right to ask!

>I thought one was to tap out the hard steel edge... Didn't make much sense to me, but then I don't claim expert knowledge in this field...

I guess that the idea is to tap the soft steel so that it can push the hard steel layer down while providing support for it at the same time. Is this right? Failure is costly on an expensive chisel...

Thanks again,

>You've got it - the soft steel deforms and gently pushes the hard steel downward. That why tapping out is a one way operation. When I'm straightening a laminated knife, for instance if I overshoot the blade is probably ruined. Tapping out deforms the steel by putting it into compression. Trying to bend it the other way puts the steel layer in tension -stretching it like this will very often crack the hardened steel.

Agreed. Just wait (caution slippery slope) till you have to tap out a thousand dollar plane blade. Makes you feel like one of folks that split diamonds - if it works great, if not worthless dust. ;)

>Wiley, you are too kind. Thank you. I'm learning that's for sure, but there so much more to learn. Every time you figure one little thing out, a dozen more questions arise.

I enjoy the discussions here and in other forums because they often make us all think about something in a different way and I'll realize something I might not otherwise figure out. The the old addage "If you want to understand something really well, try teaching (or here explaining) it to several other people."

Which meant, watch a procedure, then do that procedure, then teach someone else how to do the procedure. That's how you really learn how to do something.

That's why I stay in academic medicine -- keeps me young, and on my toes.

OT: IE7 translate tool disappeared?

>What happened to the translate tool in IE7?

I used to be able to click on a page and "Translate into English" would be on the menu. Since I upgraded to IE7 this has disappeared.

>I figgered it out...the translate tool was part of the Google toolbar, which appears to not carry over during the IE upgrade.

Once I reinstalled the Google toolbar, my translate tool was back. I actually use it a lot at work but have been too busy at work to figure out where the translate tool went.

Of course, using the translate tool has it's own challenges. Below is the translated version of the above message after discombubulation into Tranditional Chinese then back into English :-)

My figgered it outside... the translation tool is a Google tool fence part, has a liking for does not change over to in IE promotion period. Once I install the Google tool fence again, my translation tool comes back. I use it very many but too to be busy in fact in the work in the work down to cannot extrapolate where translation tool is.
