This is the thread starter for a Rotary Broach holder. For those of you that don't know what a Rotary Broach is, here's a video showing the capabiliies of a Rotary broach: [video=youtube;BuT6mrAMOxE]https://www.youtube.com/watch?v=BuT6mrAMOxE&feature=c4-overview-vl&list=PLC06981055019FA8B[/video]
There are quite a few home shop made rotary broaches out there on the net. I will be building mine loosely based on all of them and to my own liking. :whistle: I will be making , what I Believe to be, some improvements on some of the designs. It will take .500 diameter shank broaches, store bought or shop made. It will have a 3/4" straight shank so that I can mount it on my tailstock drill chuck or be able to use it in a Bridgeport R8 3/4" collet.
Here's a picture of the bearings That I just got in the mail today for it. From right to left. 2- 1 1/4" ID Sealed Ball bearings, 1/2" ID thrust bearing, 5/16" ID sealed roller bearing.
I already had the 5/16" ID bearing left over from another project.
That's all I got for now...Stay tuned
