A couple of weeks ago I started a post asking for advice on cutting a fine groove in steel. I got quite a few suggestions and all of them polite and helpful, I also received a PM from a well known member of the forum. He said that he had a few inserts that he would send to me, for free, he wouldn't even let me pay for postage.
I have just got in from a shift at work and laying on my floor a small envelope containing several high quality inserts which are very, very useful.
So a public THANK YOU VERY MUCH John Stevenson.
