There was a chip on the insert that I hadn’t noticed until it was done and I was going a little fast. I’m going for function so I lightly went over it with emory paper snd called it a day. Works well stopping the downfeed and I don’t need a tool to set the position any more.Good job.
looks like the thread finished is rough. I never threaded with carbide insert , is this common with carbide? I was thinking of buying a carbide insert holder before.
Nah, I like criticism (beginner here) and I didn’t take it as such.Ok good.
I'm sorry if I came off as being a critic, just wondering if that was normal for inserts. Now I know it’s not, I may invest in a threading insert. i have always used high speed ground by hand. Which at best is not perfect.
do you recommend a insert and tool holder.
Welcome to the forum!!!Just picked up one of these model 40’s at a local online auction (Kansas City area). It has the same z collet chuck on b&s #9 taper. I was finally able knock mine loose with the draw bar and a heavy brass hammer. I am glad I didn’t read your ordeal before hand or I might have been much more worried about getting it out. I also have a Rusnok model 80 and quickly came to the conclusion I needed a larger working envelope for some of the things I wanted to do. I had been looking at horizontal mills to put the Rusnok head on when I came access this Index mill. The 1250 pounds is about the biggest thing I can handle and get into my shop. Hope to see a lot more of your posts on the rebuild of this mill. I am new to machining but have been a metalsmith for over 40 years. Started down this road mainly to make tooling for my smithing machinery and quickly fell in love the processes.
