Universal Toolholder by LC Mason
Here's the first toolholder I made for my new Hercus lathe, to replace the 4-way turret toolpost. I'm really impressed with the rigidity and ease of adjustment.
The article appeared in Model Engineer, vol 136 No 3384, 2-15 January 1970. As that issue is probably hard to get hold of now, I've scanned the article and put the jpegs here.
