Great first lathe project, or
Great first lathe project, or experienced machinist project. A tool you will always be able to use. A 1.5” Boring Bar made from 4140 and designed to fit on your Quick Change Tool Post in one of your existing tool holders. Will hold any 5/16” Brazed Carbide or HSS Tool bit. The Design could also be easily modified to make a smaller boring bar like a 1” or ¾” bar to hold ¼” tool bits.
This was a very cost effective boring bar for me especially since it can be used for turning, threading, grooving or radius cutting in a bore. Most insert boring bars will only hold one type of insert and buying a boring bar this size for each of those operations would get very expensive.
I don’t see these around anymore. Very simple boring bar design for lathe boring. I used one like this 25 years ago, a round bar with a big chunk of key stock welded on the side, this seemed like a good upgrade to the design to integrate nicer with a Quick Change Tool Post tool holder.
I hope you enjoy the project and have a chance to make one of these boring bars of your own.
Lathe work completed on a Precision Matthews PM 1440TL and milling work completed on a Jet JMD-18PFN. Work holding on the mill with a Glacern Machine Tools vise and also use of the Glacern Machine Tools 3” Face Mill and 5/8” Indexible End Mill.
Thank you for watching!
